a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...

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, malo2-F/malo2-Ra primers from invasion gene, Parat-s/Parat-as as well as tyv-s/tyv-as primers from O-antigen gene cluster of the genus Salmonella. This method differentiated Salmonella spp., based on size ...

acute infectious gastroenteritis is one of the most common infectious diseases of humans in the world. diarrheal disease still ranks very high as a major cause of illness and death especially in developing nations. this study has been carried out to investigate enteropathogenic bacteria isolated from 2517 specimens of patients with diarrhea. the results obtained are as follow: salmonella typhim...

A total of 267 fecal and serum samples collected from individual pigs reared on a Salmonella-positive farm were subjected to bacteriological and serological examinations of Salmonella. Salmonella was isolated from 47 pigs (17.6%) and prevalence of antibody to lipopolysaccharide (LPS) of S. Typhimurium, which was partly common to S. O4, 12: d: -, was observed in 90 pigs (33.7%). Salmonella was i...

acute infectious gastroenteritis is one of the most common infectious diseases of humans in the world. diarrhea is a significant cause of death in infants. it has been estimated that up to 15% of children in developing nations die of diarrhea before 3 years of age. this study has been carried out to investigate entheropathogenic bacteria from 558 specimens of children less than 5 years of age. ...

The development of antimicrobial resistance in foodborne pathogens is a growing public health concern. This study was undertaken to determine the susceptibility Salmonella enterica subspecies isolated from Australian commercial egg layer industry. S. (n=307) flock environments (2015–2018) were obtained reference, research and State Government laboratories six states. All isolates serotyped. Ant...
