a total of 400 bovine diarrhoeic fecal specimens were obtained and conventional microbial culture, immunomagnetic separation and multiplex pcr were simultaneously carried out on samples. for detection of salmonella at genus level, inv-a universal primer was selected. in order to identifiing of salmonella typhimurium, specific primers of rfbj, fljb and flic related to gene sequence of o4, h2:1,2...

hiv-related immunosuppression significantly increases the risk of acquiring opportunistic infections. this report describes a 69-year-old man, referred to hospital with decreased consciousness and productive cough. this man was a known case of human immunodeficiency virus positive. the sputum of this patient was positive for salmonella typhimurium. pulmonary auscultation signaled brief and scat...

background : the aim of this study was to compare the antimicrobial activity of watermelon juice probioticated using differ­ent strains of lactobacilli against salmonella typhi murium. methods : probioticated watermelon juice was produced using four strains of lactobacilli (lactobacillus casei, l. acidophil­lus, l. fementum and l. plantarum ). the watermelon juice was pasteurized for 30 minutes...

Introduction: Zataria multiflora is a plant of the Lamias family. The most effective antimicrobial composition is its thymol and carvacrol. Salmonella typhimurium is a genus of Salmonella from the Enterobacteriaceae family. This gram-negative basil, optional aerobic or anaerobic, cause diseases such as inflammation of the intestine, systemic infection, and intestinal fever. Th...

Background Salmonella enterica serovar Typhimurium is one of the most important serovars of Salmonella enterica and is associated with human salmonellosis worldwide. Many epidemiological studies have focused on the characteristics of Salmonella Typhimurium in many countries as well as in Asia. This study was conducted to investigate the genetic characteristics of Salmonella Typhimurium using mu...

objectives: salmonella typhimurium is important food-borne pathogen responsible for gastroenteritis. in this work a polymerase chain reaction based enzyme linked immunosorbent assay (pcr-elisa) was developed to identify salmonella typhimurium. materials and methods: the rfb gene which is responsible for biosynthesis of the salmonella o-antigenic lipopolysaccharide was selected as the target s...

Salmonella enterica serovar Typhimurium and S.enterica serovar Enteritidis are the most frequently isolated serovars from food-borne diseases throughout the world. According to their antigenic profiles, salmonella shows different disease syndromes and host specificities. It is necessary and important to discriminate salmonella serovars from each other in order to ensure that each pathogen and i...

introduction: in iran, invasive nontyphoidal salmonella (ints) disease causes severe bacteremic illness among children <5 years old. the global yearly incidence of ints disease in children was reported to be in the 3.4 (range  2.1-6.5) million cases,  (overall incidence 49 cases (range 30-94) per 100,000 population), the ints case-fatality ratio (cfr) of 20% yielded 681,316  deaths annually. me...

The genus of Salmonella is very polymorphic and comprised of a number of genetically closely related serotypes. It is one of the emerging pathogen in food-borne disease which is often found in contaminated chicken eggs. Salmonella enterica is considered one of the major pathogens in public health worldwide. A total of 31 Salmonella isolates identified by specific antisera, which included Salmon...

OSITIVE results in attempts to hybridize Salmonella strains with Escherichia Ipcoli K-12 were first reported by BARON and his colleagues (BARON, SPILMAN and CAREY 1959; BARON, CAREY and SPILMAN 1959), and we have also observed this phenomenon with a Salmonella typhimurium wild-type strain LT-7 carrying the mutator gene mut (MIYAKE and DEMEREC 1959; MIYAKE 1959, 1960). This paper supplies more d...
