A multiplex PCR-based assay was developed for detection of Salmonella typhi and identification of other salmonella serotypes. Three primer-sets were selected from different genomic sequences, malo2F/malo2-Ra primers from invasion gene, Parat-s/Parat-as as well as tyv-s/tyv-as primers from Oantigen gene cluster of the genus Salmonella. This method differentiated Salmonella spp., based on size an...

A transplantable melanoma of Golden hamsters has been carried by the chunk method from the 15th through the 52nd generation and examined for growth characteristics and for light and electron microscopic appearance as well as for light microscopy histochemistry. Grossly, tumors were heavily pigmented and inva sive, and grew rapidly to kill the animals in 4 to 6 weeks. The growth rate remained st...

, in this study 77 and 86 bacterial strains were isolated from faeces of healthy and diarrhoeic dogs respectively. all salmonella isolates were confirmed by per method using specific inva genes. antibacterial activity of 8 routine antibiotics including tylosin, gentamycin, kanamycin, neomycin, tetracycline, oxytetracycline, chloramphenicol and sulfadiazine on the isolated bacteria was evaluated...

Background: Food safety has emerged as an important global issue with expanded international trade and various public health implications. Milk dairy products are rich in many nutrients hence offer favourable environments for the growth of food borne pathogens. Of which past decades Salmonellosis is a frequently reported zoonotic foodborne disease world. Although India leading contributor World...

AIM This study aimed to detect Salmonella species found as contaminants in chicken carcass (thigh, breast, wings, liver, and gizzard). MATERIALS AND METHODS A total of 75 chicken samples including thigh, breast, wings, liver, and gizzard (15 of each) were collected from different markets in Sohag city for detection of Salmonella species by culture methods, biochemical tests, serology, and pol...
