Background: Bacillus cereus and Yersinia enterocolitica are implicated in foodborne diseases that have major effects on human health; therefore, it is considered universal public health disorders. Essential oils and essential oils nano emulsions have a sufficient antibacterial performance against a variety of bacteria, especially multi-drug resistant bacteria. Probiotics showed several health benefits via moderating the GIT microbiota and their metabolites.

Aim: The study was designed to evaluate the biocontrol ability of cinnamon essential oil (CEO) nano emulsion and probiotics as natural antibacterial additives and reveal their bactericidal mechanism.

Methods: 250 random samples (50 raw milk, 50 rice pudding, 50 kariesh cheese, 50 yogurt, and 50 ice cream) were purchased separately from different areas in Mansoura city, Egypt, and exposed to bacteriological analysis.

Results: Bacillus cereus was found with the highest mean value of 66 × 107 ± 1.3 × 108 CFU/g in raw milk and the lowest mean value of 28 × 107 ± 2.6 × 107 CFU/g in kariesh cheese while Y. enterocolitica was found in 64% of the total inspected samples with the highest incidence (84%) in yogurt. The toxinogenic potential of the tested pathogens has been evaluated by multiplex PCR pointing nhe A and ces genes for B. cereus isolates while targeting in Y. enterocolitica 16s rRNA, and YST gene. Different concentrations (0.17%, 0.25%, 0.5%, 0.8%, 1%, 1.5%, and 2%) of cinnamon oil nano emulsion were employed in this study. CEO nano emulsion had the highest reduction rate at a concentration of 1.5% in the case of B. cereus and 2% in the case of Y. enterocolitica. Among different types of probiotics, the best one which showed inhibitory potential against B. cereus and Y. enterocolitica was L. plantarum.

Conclusion: Lactobacillus plantarum and CEO nano emulsion at a concentration of 2% have the highest reduction rate against Y. enterocolitica, while L. plantarum and CEO nano emulsion at a concentration of 1.5% has the best antibacterial effect against B. cereus. In conclusion, more attention is required for both safety and quality in dairy products through the application of natural additives such as essential oils and probiotics.

Keywords: Essential oils, Cinnamon oil, Bacillus cereus, Y. enterocolitica, L. plantarum.


Bacillus cereus is considered one of the utmost common food-borne pathogens in foodstuffs (Rahnama et al., 2023). They were mentioned as “aerobic endospore-forming micro-organisms” which broadly blow out over the world (Zhou et al., 2023). The pathogenicity of this organism rests on frequent exogenic enzyme creation, the capability of forming biofilms, and the existence of toxin-encoding genes. It is related to a food poisoning syndrome characterized by diarrhea and gastrointestinal disturbances (Li et al., 2023). Bacillus cereus ranked as the fourth greatest reason for foodborne diseases by EFSA and ECDC in the European Union (Elafify et al., 2023).

Yersinia enterocolitica is involved in different human disorders such as gastro-enteritis, sepsis, appendicitis, and lymphadenitis (Ahmed et al., 2023). Yersiniosis as a gastrointestinal contagion comes afterward campylobacteriosis and salmonellosis (Zadernowska et al., 2014) demonstrated by lymphadenitis, diarrhoea, appendicitis, and arthritis (Tavassoli et al., 2019). Yersinia enterocolitica resists numerous antibacterial agents and is considered one of the pathogenic drug-resistant bacteria with a public health importance (Sadek et al., 2014; Bonardi et al., 2018).

Food additives that are used in the food industry to prolong shelf life may cause intoxication, and severe diseases as cancer. To avoid this problem, the application of natural extracts from herbs to limit the growth of micro-organisms might be a practical solution (El-Sayed and El-Sayed, 2021)

Lactic acid bacteria are commonly reflected as probiotics which have great health importance via moderating the metabolites and microbiota (Fang et al., 2023). Therefore, they were used as preservatives in the food chain (Hamad et al., 2022). Lactobacillus plantarum has an aggressive influence against food micro-organisms (Tian et al., 2022). Finally, efficient foods or probiotic-supplemented food received more attention because of the awareness of healthy and beneficial products targeting good wellbeing (Ali et al., 2023; Hussain et al., 2023). The number of cells per milliliter and its therapeutic doses determine the probiotic potential (Begum et al., 2017). A probiotic food should not exceed 1.0 × 106 cfu/g of alive microbes.

In accumulation to being a biopreservative, EOs mentioned as generally recognized as safe due to their effective antibacterial role in the food industry (Es et al., 2017). They can inhibit spoilage and pathogenic bacteria through their phenolic constituents and polypeptides (Bakhtiary et al., 2018) and improve nutritive value and organoleptic properties (Kholif and Olafadehan, 2021). Among them, cinnamon essential oil (CEO) has been used as an antifungal and antimicrobial agent (Paudel et al., 2019) due to the presence of cinnamic acid, eugenol, and cinnamaldehyde (Siripatrawan, 2016). It has broad-spectrum antimicrobial activities; in addition, it is characterized by its special aroma and medicinal properties (Nazzaro et al., 2013). Nano emulsions are biphasic dispersions of water and oil either water in oil microemulsions or oil in water microemulsions or (O/W), alleviated by an emulsifier. The exceptional features of these nanostructures diverge from their parent structures chemically, biologically, and physically. This potential request of nanotechnology is to prolong shelf-life, nutritional additives, coloring, flavoring, and food safety via using antimicrobial ingredients for food (Oladipo et al., 2020). Therefore, this study examined the preservative action of CEO nano emulsion and probiotics and how those could affect pathogenic bacteria.

Materials and Methods

Collection of samples

Two hundred and fifty samples of raw milk, yogurt, kariesh cheese, ice cream, and rice budding (50 each) were purchased randomly from different markets at localities in Dakahlia Governorate, Egypt, from September 2022 to March 2023. In sterile containers, samples were collected and transferred immediately to an ice box for isolation and examination.

Microbiological analysis

Preparation of samples

Samples collected were 25 ml of milk and 25 g of yogurt, kareish cheese, rice pudding, and ice cream then homogenized in a sterile jar containing 225 ml of tryptone soya broth. Kareish cheese was mixed with 2% sodium citrate to accelerate homogenization (Salfinger, 2015).

Isolation and quantification of B. cereus

It was done through duplicates of BcSAB plates with polymyxin B supplement first then add the egg yolk emulsion. Incubated at 35°C for 24–48 hours. Suspected colonies of B. cereus appeared crenate, about 5 mm in diameter, and had a unique turquoise to peacock blue color. Then the recovered colonies were counted and calculated as the total B. cereus count. Three to five typical colonies were purified on TSA slants and incubated at 35°C for 24 hours (Oxoid, 2002).

Identification of Y. enterocolitica

Pre-enrichment of the sample (1 ml) by 10 ml of PBS supplemented with cefsulodin and novobiocin is necessary. Tubes were incubated at room temperature for 5–7 days. Streaking on selective CIN agar plates. Then incubated at 37°C for 48 hours. Characteristic colonies appeared as bull's eyes (Drake et al., 2018).

Molecular confirmation of isolate

By following manufacturer instructions, the DNA of Bacillus and Yersinia isolates have been extracted by QIAamp DNA Mini Kit. Amplification of the specific bacterial targets was done by PCR using DreamTaq™ Green PCR Master Mix (2×), Emerald Amp GT PCR master mix (TaKaRa, Japan), respectively (Koua et al., 2014; Owusu-Kwarteng et al., 2017) (Table 1).

Table 1. Oligonucleotide sequences of the primers used in the present study.

Preparation of essential oils nano emulsion

Colloidal nano suspension from cinnamon seeds was prepared by ethanolic extract using solvent evaporation/micelles formation with some modification (Singh et al., 2023). CEO nano emulsions with concentrations of 0.17%, 0.25%, 0.5%, 0.8%, 1%, 1.5%, and 2% (v/v) for each were purchased from Nakaa Nanotechnology Network. Experiments and interpretation were done according to previous studies (NCCLS 2012; Kaskatep et al., 2016).

Antimicrobial activity analysis

Disc diffusion was done by using Mueller-Hinton agar following the guidelines of CLSI (2015, 2017). Then bacteria were spread on the plate with 1.5 × 107 CFU/ml density according to Lahtinen et al. (2007. Ampicillin (AM 10 µg), ciprofloxacin (Cip), amoxicillin-clavulanic acid (AMC 20/10 µg, and erythromycin (E15) discs were tested.

Antibacterial activity of different probiotic strain

Preparation of probiotic

Lactobacillus plantarum, L. rhamnosus, and L. acidophillus were evaluated via agar well diffusion method following previous studies (Hamad et al., 2023). Wells (6 mm) were bored on the plates and 100 µl free supernatant containing antibacterial activity was added, ampicillin was used as a positive control, while the nutrient broth was utilized as a negative control. Incubation was done for 24 hours at 37°C and the inhibition zone was measured and a clear zone was noted in mm referring to the antibacterial influence of different probiotic strains.

Antibacterial activity of CEO nano emulsion

Different concentrations of CEO nano emulsion were presented in wells that were swabbed before with overnight cultures of bacteria. The test was done on triplicates as probiotic inoculation (Hulankova, 2022).

Statistical analysis

Data were represented as Mean ± SD. ANOVA was done with SPSS and statistical significance was estimated at p < 0.05 (Feldman e t al., 2003).

Ethical approval

Not required for this study.


Occurrence of B. cereus in the examined samples

Bacillus cereus was found in milk, yogurt, ice cream, kareish cheese, and rice pudding samples by 72%, 70%, 32%, 30%, and 44%, respectively (Table 2). Although nheA and ces genes were detected at 100% of rice pudding, nheA gene were found only at 50% of yogurt and raw milk as mentioned in Tables 3–5 and Figure 1.

Table 2. Prevalence of B. cereus in the examined samples.

Table 3. Molecular identification of certain B. cereus among the examined samples.

Occurrence of Y. enterocolitica and virulence genes

Yersinia enterocolitica was found in 160 samples out of 250 (64%) with the highest incidence of 84% followed by 76%, 66%, 62%, and 32% in yogurt, kariesh chees, raw milk, rice pudding, and ice cream, respectively, as shown in Table 4. Both 16s rRNA and yst gene were detected in 100% of tested isolates as illustrated in Table 5 and Figures 2 and 3.

Antibacterial susceptibility against B. cereus and Y. enterocoltica isolates

Bacillus cereus isolates were highly sensitive to ampicillin, middle sensitive to Amoxicillin-clavulanic and ciprofloxacin with no effect of erythromycin, while, Y. enterocolitica was highly sensitive to ampicillin, intermediate to Amoxicillin-clavulanic, and resistant to ciprofloxacin and erythromycin as depicted in Table 6.

Antibacterial activity of probiotic

Bacillus cereus showed high sensitivity to L. plantarum, intermediate L. acidophillus then L. rhamnosus with 40.33 ± 5.48, while in Y. enterocoltica L. plantarum showed the strongest antibacterial activity with DIZs 38 mm, followed by L. acidophillus and L. rhamnosus (Table 7).

Antibaterial activity of CEO nano emulsion against B. cereus and Y. enterocoltica isolates

Bacillus cereus shows high sensitivity for 1.5% CEO nano emulsion reaching 38.00 ± 4.35, while Y. enterocoltica showed inhibition at 2% with 38.67 ± 2.4. p < 0.05 showed a significant decrease in values (Mean ± SE) in Table 7 which assumed that L. plantarum, 1.5% CEO, and 2% have a more powerful effect against the examined isolate.


Dairy foods contaminated by contagious microorganisms are considered the most critical matter of human-being health and safety worldwide. Spoilage of dairy foodstuffs is highly risky because of the ability of raw milk and its dairy products to accelerate progression. Bacillus cereus is recognized as a significant pathogenic microorganism that is characterized by diarrheal and emetic syndrome (Radmehr et al., 2020; Han et al., 2023).

Thus, B. cereus is a significant microbe that threatens human beings whether their toxins are present or not. In comparison with our findings, Hefny et al. (2020) and Osama et al. (2020) isolated B. cereus from 40% of tested Kareish cheese while (Heikal and Al-wakeel, 2014; Ibrahim et al., 2015) failed to isolate B. cereus in their examined cheese samples. In opposite to our result, Adam et al. (2021) and Fetouh et al. (2022) indicated that the occurrence of B. cereus in yogurt samples was at 8.0%, and 4.0%, respectively, while it could not be detected in yogurt samples by Tirloni et al. (2017). The absence of growth or even low incidence observed might be owing to the low pH < 5.

Lower results were reported by Owusu-Kwarteng et al. (2017) who found that B. cereus is isolated at 47.00% from raw cow milk in Ghana. Also, Mohamed et al. (2016) declared that B. cereus was found in 60.00% of raw cow milk samples. Abraha et al. (2017) reported that B. cereus rate exists at 8.80% in raw cow milk samples in Ethiopia.

Although B. cereus was detected at 32% in ice cream, a higher rate (62.7%) was defined by Messelhäusser et al. (2010). Consequently, variation in B. cereus rate is owing to different bacterial loads and poor hygiene standards during the preparation and production process. Bacillus cereus is recurrently isolated from raw milk because of pasteurization process resistance (Tirloni et al., 2017).

According to our result, B. cereus was isolated at 22 (44%) of the examined rice pudding and this disagreed with Morsy et al. (2022) who isolated B. cereus at 84% in rice pudding samples. The same findings were defined before (Mohamed et al., 2016; Amin, 2017; El-Sherif et al., 2021). While, higher results were also reported (Hussein et al., 2015; El-Karamani, 2017; El-Zmakan and Mubarak, 2017; El-Sherif et al., 2021).

Our study discussed the mechanism of food contamination with B. cereus. Certainly, the main source of contamination is poor sanitation and cross contamination. Overall, the raw ingredients and the post-pasteurization contamination might increase the prevalence of B. cereus. This concluded that firm cleaning administration must be approved to control B. cereus with the aim of assuring high quality and safety products.

According to our result, nheA gene was found in 50% of B. cereus isolated from each raw milk and yogurt. Higher occurrence rates were recorded by Eltokhy et al. (2021) who detected nheA in all isolates. Fetouh et al. (2022) stated that non-hemolytic (nheA) and cytotoxic K (cytK) genes were involved in food poisoning. Hefny et al. (2020) who failed to detect ces gene, detected cytk in 47% of all isolated B. cereus while, nhe and hbl were detected at 52% and 33%, respectively. Bianco et al. (2020) detected sich cytotoxic genes in 35%–100% of their isolated strains.

Bacillus cereus revealed high sensitivity to ampicillin followed by amoxicillin, clavulanic, and ciprofloxacin with high resistance toward erythromycin and this might be due to the misuse of antibiotics in dairy farms. This finding differs from Ahmed et al. (2023) who said that all examined isolates were 100% sensitive to erythromycin, 100% resistant to tetracycline, and intermediate sensitive to ciprofloxacin. EFAS stated that probiotics to be used in food stuff; it should not have antimicrobial resistance genes (EFSA, 2007).

Yersinia spp., is capable of growing in both anaerobic and aerobic situations. Nguyen et al. (2019) concluded that Y. pseudotuberculosis, Y. enterocolitica, and Y. pestis are pathogenic and transferred through contaminated milk. Yersiniosis is stated as a zoonotic syndrome with a public health importance. EFSA (2009) revealed that Y. enterocolitica in the whole European Union is considered one of the most informed zoonoses. Yersinia enterocolitica proliferated in the lower small intestine and upper large intestine, pusjing the organism establishment (Chlebicz and Śliżewska, 2018). Consequently, Yersiniosis causes gastric infection because of the improper handling and cooking of animal-origin foods during preparation (Tavassoli et al., 2018).

Yersinia was detected in 64% (160 out of 250) of the examined products. This result was classified as following: 33(66%) raw milk, 42(84%) yogurt samples, 16(32%) ice cream samples, 38 (76%) kariesh cheese samples, and 31(62%) from rice pudding. However, Gṻven et al. (2010) isolated Y. enterocolitica from raw milk at 1.33%, while Darwish et al. (2015) isolated it at 38.5%. Hassan and Afify (2007) secluded the lowest incidence at 2% in Kareish cheese, while Basyoni and Elsheikh (2005) isolated it by 16.67%, and Basha et al. (2008) isolated it at 14%. A higher incidence of Y. enterocolitica was reported in kariesh cheese and yogurt at 60% and 84%, respectively. This might be due to poor hygiene during manufacture. Basha et al. (2008) confirmed that gathering Kareish cheese samples from shops and street retailers could clarify the poor quality.

In small-scale ice cream, Gṻven et al. (2010) recorded the lowest incidence of Y. enterocolitica at 2.67% and Khalifa et al. (2007) could isolate it at 12.5%. Nearly similar results have been recorded by AlShammary and Madi (2016) who isolated it with a percentage of 30%. Being psychrotrophic bacteria elevates their prevalence in ice cream which affect badly on cold food chain.

Similar results were recorded by Harakeh et al. (2012), and Ali and Al-Samarai (2020) who isolated Y. enterocolitica at 12%, and 9.75%; respectively. Yersinia enterocolitica was isolated at 5.78%, 5.3%, and 3.3%, respectively (Ali et al., 2015; Ozdemir and Arslan, 2015). While, higher incidence was recorded by Darwish et al. (2015) and Ahmed et al. (2019) at 46%, and 22%, respectively, whereas Zeinhom and Abdel-Latef (2014) could not isolate it.

PCR was able to identify pathogenic strain genes in the isolates. We focused on virulence-associated genes of 10 isolates of Y. enterocolitica. These genes were 16S rRNA for detection and yst for virulence. PCR results declared that genes were found in all isolates. Younis et al. (2019) detected tetA and blaTEM genes in all eight isolates. On the other hand, it is remarkable that the YST gene cannot be detected (Peruzy et al., 2017).

Yersinia enterocolitica revealed high resistance to ciprofloxacin, and erythromycin. Meanwhile, they were intermediate sensitive to AMC. Moreover, they were highly sensitive to ampicillin. While Abdelwahab et al. (2021) reported that Y. enterocolitica was highly sensitive to norfloxacin and meropenem (79.0% for each). Then, gentamycin was recovered at 68.4% and middle sensitive to doxycycline by 63.2%. These results demonstrated that Y. enterocolitica had multiple antibiotic resistances. Thus, we tried to demonstrate other alternatives as natural probiotics and essential oils.

The misapplication of the antibacterial agents could raise the bacterial resistance. As B. cereus and Y. enterocolitica were examined against several antibiotics. All tested isolates showed high resistance levels. Probiotics that are applied in some foodstuffs and pharmaceutics are regarded to be safe, and they should not have transportable antibiotic-resistance genes (EFSA, 2007). Montassier et al. (2021) stated that antibacterial potential is a critical feature to assess the use of probiotics in the food industry (Aditya et al., 2020). According to the current study, L. plantarum is characterized by powerful activity against B. cereus and Y. enterocolitica strains.

Lactobacillus plantarum (MK850930) showed inhibition zones of 40 mm in B. cereus and 38 mm in Y. enterocolitica. Ahmed et al. (2023) said that L. plantarum has an antimicrobial effect toward B. cereus EMCC1006. These studies disagreed with Yusra and Likaa (2013) who reported that in the case of B. cereus, L. plantarum MIC was 0.07 ml. Approaches of probiotics might successfully inhibit pathogens such as L. monocytogenes (Wu et al., 2022), other studies stated that L. casei IMAU60214 was effective against Escherichia coli (Rocha-Ramírez et al., 2023). Similarly, L. fermentum LBF433 and L. casei LBC 237 have sufficient action against Salmonella (Lando et al., 2023).

Our study disclosed that L. plantarum had a significant inhibitory action on foodborne pathogens such as Y. enterocolitica and B. cereus. The main effect of the essential oils was attributed to their antimicrobial properties, and the ability to dissolve the cytoplasmic membrane of the bacterial cells (Kaskatep et al., 2016; Ferrari et al., 2012). One of the approaches to deal with these hydrophobic compounds is by dispersing them in nano emulsion delivery system (Singh et al., 2023). Dávila-Rodríguezet et al. (2019) reported that one of Eos disadvantages on food is its flavor effect in food products. To solve these issues, CEO can be encapsulated in nano emulsions to increase the stability, solubility, and potential activity of CEO (Akhavan et al., 2018).

Paudel et al. (2019) stated that CEO has a proper source of antifungal and antimicrobial compounds. This activity is basically linked to eugenol, cinnamaldehyde, and cinnamic acid (Siripatrawan, 2016). In comparison with Eos nonencapsulation, nanoemulsions were extra active against bacteria, needing less than 50% EOs to decrease 5-log bacterial count. Numerous studies discussed the effectiveness of CEO against food-borne pathogens (Cava-Roda et al., 2010; Aliakbarlu et al., 2013).

CEO nano emulsion has effective power on food-borne diseases. In our study, B. cereus was found to be delicate to CEO nano emulsion 0.5% with IZD 34 mm, Y. enterocolitica sensitive to CEO nano emulsion 2%. Gupta et al. (2008) reported that cinnamon oil is very supportive against Bacillus spp. with MIC 1.25%. Azadi et al. (2023) concluded that CEO nano emulsion have a notifiable activity toward Staphylococcus aureus and B. cereus more than S. typhimurium and E. coli (O157:H7).

Sharma et al. (2022) stated that the CEO was the most operative as an antimicrobial agent. It is recognized by the presence of cinnamaldehyde. Cinnamaldehyde is an effective natural antioxidant that prevents stomach ulcers, preventing both strains of Helicobacter pylori, also it can be inhibited through the growth of yeast, molds, and bacteria (Basak et al., 2021). Oregano, basil, rosemary, and thyme were branded as the most favorable active antimicrobial EOs against Y. enterocolitica recently which deserve further studies (Durofil et al., 2022). It was found that Y. enterocolitica was sensitive to CEO nano emulsion 2% in our study. Hulankova (2022) concluded that Y. enterocolitica and Y. pseudotuberculosis are multi resistant bacteria against cinnamon oil by MICs (median 414 and 207 μg /ml, respectively). Koua et al. (2014) referred to the importance of micro-organisms not to acquire resistance toward essential oils. CEO contains cinnamaldehyde (68.79%) which was proven to have high antibacterial activity against G + ve bacteria (Es et al., 2017). Yersinia enterocolitica was the most sensitive bacteria to Cinnamomum cassia EOs with a zone of inhibition (16.67 mm). Klūga et al. (2021) examined 14 types of Eos against Y. enterocolitica and found extreme action against pathogenic microbes.


Entero-pathogenic Yersinia and B. cereus showed a great resistance level toward some antibiotics. Other approaches were used effectively against Y. enterocolitica and B. cereus such as L. plantarum which have a functional inhibition potential. CEO was effective against both Yersinia and Bacillus spp. Therefore, EOs and probiotics can be hopeful alternate inhibitors for these multiresistance strains.
