Salmonella enterica causes a range of diseases. Salmonellae are intracellular parasites of macrophages, and the control of bacteria within these cells is critical to surviving an infection. The dynamics of the bacteria invading, surviving, proliferating in and killing macrophages are central to disease pathogenesis. Fundamentally important parameters, however, such as the cellular infection rat...

Skinless precooked, uncured sausage links with and without potassium sorbate (0.1% wt/wt) were inoculated with salmonellae, Staphylococcus aureus, Clostridium perfringens, and Clostridium botulinum and held at 27 C to represent temperature abuse of the product. Total counts of uninoculated product showed that the normal spoilage flora was delayed 1 day when sorbate was present. Growth of salmon...

The current study was conducted to investigate the prevalence of Salmonella spp. in turkey and to determine the antimicrobial resistance pattern of the isolated Salmonellae. Two hundred and fifty turkeys were randomly selected for cloacal soab samples preparation, and the samples were investigated for Salmonella isolation. Identification of the isolated Salmonella was performed using standard b...

Salmonella Typhi is the cause of typhoid fever, a disease that has challenged humans throughout history and continues to be a major public health concern. Unlike infections with most other Salmonellae, which result in self-limiting gastroenteritis, typhoid fever is a life-threatening systemic disease. Furthermore, in contrast to most Salmonellae, which can infect a broad range of hosts, S. Typh...

Salmonella and Listeria spp. are frequently detected in poultry meats. Conventional isolation and identification methods to detect these microrganisms in food are laborious and time-consuming. In the present study the occurrence of Salmonellae and Listeriae on 362 samples of retail poultry in Caserta, South Italy was evaluated and standard microbiological and rapid methods were compared. Furthe...

Six hundred lactating dairy buffaloes from four districts (Lahore, Sialkot, Narowal and Okara) of Punjab, Pakistan were screened for subclinical mastitis using White Side Test and subsequent bacterial isolation. Overall prevalence of subclinical mastitis was 44% (264/600). It was the highest (58%) in animals kept as individual holding at backyards followed by small holdings in periurban area (4...

-This study was undertaken to determine the comparative incidence of drug-resistant coliforms and salmonellae in the water and bottom sediments of six coastal canal communities which are used heavily for recreational activities. Of a total of 423 coliforms, 300 fecal coliforms and 100 salmonella isolates examined, 74.950 coliforms, 61.3% fecal coliforms and 71.0°,/o salmonellae were resistant t...
