“…Bacillus cereus is a ubiquitous Gram-positive spore-forming bacteria, commonly found in raw or processed foods (Gracias and McKillip 2011;Berthold-Pluta et al 2015). Bacillus cereus may cause two different types of foodborne disease syndromes: emetic and diarrhoeal (Merzougui et al 2014).…”

The prevalence of Bacillus cereus in raw milk from dairy herds in Inner Mongolia and associated risk factors were determined. In total, 160 raw milk samples collected from 2014 to 2015 and examined by culture methods to isolate B. cereus. Fifty-five samples (34.38%) were positive. The prevalence of B. cereus in raw milk was significantly (P < 0.01) lower in winter (15%) than in summer (50%). The highest prevalence of B. cereus in raw milk was seen in samples collected from small-to medium-sized dairy herds in summer. The results of this study indicated that B. cereus could be a common pathogen in Inner Mongolia because of its high prevalence. It is essential for dairy farmers and producers to strengthen hygienic practices in summer to control B. cereus contamination in raw milk. These results will be useful in establishing proper management procedures to reduce the prevalence of B. cereus in raw milk.

“…Some strains of Bacillus cereus are considered nonpathogenic but others have been implicated in cases of human foodborne illness(Berthold-Pluta et al, 2015). For viruses, all pigs showed the presence of torque teno sus virus (TTSuV) and porcine endogenous retrovirus (PERV), which are ubiquitous and were also present in the virus inoculum used for challenge.…”

On a world-wide basis, co-infections involving porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are common and contribute to a range of polymicrobial disease syndromes in swine. Both viruses compromise host defenses, resulting in increased susceptibility to infections by primary and secondary pathogens that can affect growth performance as well as increased morbidity and mortality. An experimental population of 95 pigs was co-infected with PRRSV and PCV2. At 70days post-infection (dpi), 20 representative pigs were selected as having the best or worst clinical outcome based on average daily gain (ADG) and the presence of clinical disease. Worst clinical outcome pigs had prolonged and greater levels of viremia as measured by qPCR. Serum, lung and fecal samples collected at 70 dpi were analyzed using a comprehensive DNA microarray technology, the Lawrence Livermore Microbial Detection Array, to detect over 8000 microbes. Bacterial species, such as Bacillus cereus, were detected at a higher rate in the serum of worst performing pigs. At the level of the fecal microbiome, the overall microbial diversity was lower in the worst clinical outcome group. The results reinforce the importance of pathogen load in determining clinical outcome and suggest an important role of microbial diversity as a contributing factor in disease.

“…In vitro tests, under high concentrations of the toxin nhe, the target cells suffer quick cellular apoptosis, concomitant with a necrotic condition (Liu et al, 2017). The genes of the complex HBL are also associated with a strong degenerative effect on the cell membrane (Berthold-Pluta et al, 2015), which shows the degree of pathogenicity of the strains of B. cereus group.…”

Unsatisfactory microbiological aspects of UHT goat milk, soymilk and dairy beverage of goat milk and soy protein: A public health issue

et al. 2020

Spore forming bacteria can play an important role in food quality and safety as spoilage and pathogenic microorganisms due to resistance to heat-treatment. However, there are limited number of studies focused on evaluate the microbiological quality and the occurrence of these bacteria in UHT goat milk, soymilk and dairy beverage of goat milk and soy protein. On this context, 75 samples of these beverages were evaluated regarding heterotrophic mesophilic microorganisms by conventional plate count and selective methods to detect microorganisms from Bacillus cereus group and Clostridium perfringens. Population counts greater than 10 4 CFU.ml-1 of heterotrophic mesophilic microorganisms were observed in 80% of the lots of goat milk and 100% of the lots of soymilk and dairy beverage of goat milk and soy protein. The presence of bacteria belonging to B. cereus group was observed in 16%, 52% and 44% of goat milk, soymilk and dairy beverage of goat milk and soy protein, respectively. C. perfringens was isolated from 8% samples of UHT soymilk. The frequency of genes hblA, hblB, hblC, nheA, nheB, nheC in 29 isolates obtained from these products was 62%, 48.2%, 96.5%, 79.3%, 68.9% and 79.3%, respectively. The microbiological quality of the evaluated products was unsatisfactory.
