The food chain has been recognized as one of the key routes of transmission of antibiotic resistance from animal to human bacterial populations. The increasing numbers of reports on the presence of antibiotic resistance in food grade bacteria are indicative of an important public health problem globally. There is an urgent need to limit the spread of resistance genes within food grade bacteria,...

Pathogenic food-borne bacteria have been associated with severe morbidity and mortality in humans and animals. This study was aimed at determining the prevalence of Staphylococcus aureus, Salmonella spp., and Escherichia coli present in cattle and pigs slaughtered in selected abattoirs in Vhembe District and at determining the susceptibility of the isolates to antibiotics. A total of 176 swab s...

conclusions the results showed that p. americana is a possible reservoir and potential vector of some pathogenic agents. results one hundred percent of cockroaches had bacterial infections. culturing of the external parts wash homogenates resulted in the isolation of escherichia coli, proteus, serratia, klebsiella, enterobacter, pseudomonas, staphylococcus aureus, streptococcus, enterococcus, c...

Frequent monitoring of antimicrobial susceptibility in bacteria from any source (i.e. animal, food or human) is extremely valuable activity to ensure global public health. The acquired resistance among pathogenic bacteria may become evident clinically in events which fail to get the expected therapeutic response of an antimicrobial agent which had been successfully used for many years. In such ...

While the potential emergence of food spoilage and pathogenic bacteria with resistance to lantibiotics is a concern, the creation of derivatives of starter cultures and adjuncts that can grow in the presence of these antimicrobials may have applications in food fermentations. Here a bank of Lactococcus lactis IL1403 mutants was created and screened, and a number of novel genetic loci involved i...

The antibacterial effect of thyme, peppermint, sage, black pepper and garlic hydrosols, widely used in food products as drinks and food additives, were tested for their inhibitory effects against Bacillus subtilis and Salmonella enteritidis. Single and combined hydrosols of previous common herbs were used to evaluate in vitro the antibacterial activity against these pathogenic bacteria. The obt...

background food born pathogenic bacteria are the most important agents of infections in humans, and food spoilage also results in economic losses in food industry. objectives the aim of this study was the evaluation of chemical components, total phenolic content, antioxidant and antibacterial activities of artemisia dracunculus essential oil. materials and methods the essential oil of tarragon ...

OBJECTIVE To characterize mechanisms of hand contamination with faecal indicator bacteria and to assess the presence of selected pathogens on mothers' hands in Tanzania. METHODS A household observational study combined with repeated microbiological hand rinse sampling was conducted among 119 mothers in Dar es Salaam, Tanzania. All hand rinse samples were analysed for enterococci and Escherich...

Carbapenem antimicrobials are critically important to human health and they are often the only remaining effective antibiotics for treating serious infections. Resistance to these drugs mediated by acquired carbapenemase enzymes is increasingly encountered in gram-negative bacteria and is considered a public health emergency. Animal origin food products are recognized as a potential source of r...
