“…When animals are infected with Salmonellosis, high economic loss occurrs due to increased mortality and morbidity, and this diseased animals may act as the source of infections for humans through direct or indirect contacts with animals (Libby et al, 2004). Contamination of the environment and food with Salmonella mainly happens by the fecal wastes of the infected animals and humans (Ponce et al, 2008) as Salmonella colonizes mainly in the gastrointestinal tract (Abulreesh 2012). …”

Objective: This study was conducted to determine the prevalence of Salmonella in milk (farm bulk milk, raw market milk) and cheese (kareish, white soft cheese) samples that were collected randomly from farms, supermarkets, small vendors and shops in different districts of Mansoura city, Egypt. Materials and methods: A total of 100 farm bulk milk, raw market milk, kareish cheese and white soft cheese samples (25 of each) were screened for the prevalence of Salmonella spp. The Salmonella isolates were isolated and identified by conventional bacteriological techniques, which were further confirmed genetically by polymerase chain reaction (PCR) based on the presence of invA gene. Finally, the isolates were serotyped. Results: Salmonella could be detected in 15%(n=15/100) samples with a prevalence of 12%(n=3/25), 24%(n=6/25), 20%(n=5/25) and 4%(n=1/25) in raw market milk, raw farm bulk milk, kareish cheese and white soft cheese, respectively. The Salmonella isolates were serotyped into S. enteritidis 33.3%(n=9/27) which was the most frequent, followed by S. typhimurium 25.9%(n=7/27), S. heidelberg 14.8%(n=4/27), S. infantis 11.11%(n=3/27), S. tsevie 11.11%(n=3/27) and S. haifa 3.7%(n=1/27). Conclusion:The present study confirms the presence of Salmonella in milk and cheese samples in Mansoura, Egypt, indicating that the dairy products can act as potential sources of Salmonella infection. Thus, appropriate hygienic measures are suggestive for combating Salmonellosis in Egypt.

“…[18][19][20][21][22][23][24][25][26][27][28] There are several previous microbiological surveys of food animals on farms, fresh meat samples from slaughterhouses and retail stores, exported fresh meat samples and vegetables, and stool samples from both healthy individuals and hospital patients from Thailand and several other countries. [29][30][31][32][33][34][35][36][37][38][39][40][41] Almost all of these reports emphasized the ability of foodborne bacteria in causing gastrointestinal infections, especially Salmonella, Campylobacter, and Arcobacter species, though only a few studies described antibiotic-resistant E. coli. Many Salmonella species were isolated from these samples, most of which were resistant to antibiotics.…”

Objectives: The aim of this study was to determine the prevalence of antibiotic-resistant bacteria, especially extended-spectrum beta-lactamase (ESBL) producing Escherichia coli, in samples from healthy adults, foods, food animals, and the environment in selected areas of Thailand. Methods: Samples were collected from stool specimens from adult food factory and food animal farm workers, fresh and cooked foods sold at markets, rectal swabs of healthy pigs and chickens, fresh pork meat from slaughterhouses, water samples from canals as well as fish and shrimp farm ponds, and stagnant water sources on pig farms. Antibiotic susceptibility was determined using the disk diffusion or agar dilution methods. Extended-spectrum beta-lactamase production was assayed using a double disk diffusion method. Results: Among 544 healthy adult food factory workers, 75.5% were positive for ESBL producing E. coli, while 77.3% of E. coli isolated from 30 healthy animal farm workers were positive. Amongst healthy food animals, ESBL producing status among E. coli isolates were more commonly detected in pigs (76.7%) than broilers (40%). Extended-spectrum beta-lactamase producing E. coli seemed to be more prevalent in fresh meat samples than in fresh vegetables, in fresh foods than in cooked foods, and in water samples collected from the animal farms than those from canals and fish and shrimp ponds. Conclusions: Extended-spectrum beta-lactamase producing E. coli isolates are prevalent amongst healthy individuals, foods along the food production chain from farms to consumers, and in the environment in selected areas in Thailand.

“…In addition, molecular biology techniques may be used for rapid detection of Salmonella in foods: TaqMan PCR (Kimura et al, 1999), PCR amplification of a 152-bp segment of the gene hns , real-time PCR (Malorny et al, 2004), PCR, dot blot hybridization, RAPD and ERIC-PCR (Shabarinath et al, 2007), PCR amplification of the gene invA (Upadhyay et al, 2010) and uniplex and multiplex PCR (Raj et al, 2011).…”

“…When testing salmonellas from aquaculture environments, the selection of antibiotics depends on the origin of the isolates, but usually covers a range of families, including the tetracyclines, sulfonamides, quinolones, macrolides and aminoglycosides (Ponce et al, 2008;Carvalho et al, 2009). The classification of bacteria according to susceptibility or resistance to antibiotics is based on the criteria of the Clinical and Laboratory Standards Institute (CLSI, 2009).…”
