We have recently shown that Salmonella Gallinarum type 1 fimbriae with endogenous mannose-resistant (MR) variant of the FimH protein increase systemic dissemination of S. Gallinarum and colonization of internal organs in comparison to the S. Gallinarum fimH knockout strain or the mutant expressing mannose-sensitive (MS) FimH variant from S. Enteritidis. Elaborating from these studies, we propos...

This experiment was conducted to evaluate anti-Salmonella enteritidis (anti-SE) bacteriophage as feed additives to prevent Salmonella enteritidis in broilers. The experimental diets were formulated for 2 phases feeding trial, and 3 different levels (0.05, 0.1 and 0.2%) of anti-SE bacteriophage were supplemented in basal diet. The basal diet was regarded as the control treatment. A total of 320 ...

Short-chain fatty acids have been widely used as feed additives to control Salmonella in poultry. Data on the use of butyric acid in poultry are lacking. In this study, powder form and coated butyric acid were compared in their ability to reduce Salmonella colonization of ceca and internal organs shortly after infection of young chickens with Salmonella enteritidis. In the first trial, 4 groups...

Green fluorescent protein-labeled Escherichia coli O157:H7 and Salmonella enterica serovar Enteritidis were inoculated at 10(7) CFU/g into cow, hog, or chicken manure. Ten- or 11-day-old soldier fly larvae (Hermetia illucens L.) (7 to 10 g) were added to the manure and held at 23, 27, or 32 degrees C for 3 to 6 days. Soldier fly larvae accelerated inactivation of E. coli O157:H7 in chicken manu...

BACKGROUND Non-typhoidal Salmonella (NTS) is a public health problem worldwide and particularly in Africa with high disease burden. This study characterized Salmonella isolates from humans in Ghana to determine serovar distribution, phage types, and antimicrobial resistance. Further, the clonal relatedness among isolates was determined. METHODS One hundred and thirty-seven Salmonella isolates...

More than 2,500 serovars of Salmonella species have been reported to date. A multiplex-PCR method was developed and evaluated for discriminating the four Salmonella enterica subsp enterica serovars, namely, S. Enteritidis, S. Typhimurium, S. Thompson and S. Infantis, most commonly isolated in Japan. Twenty-two serovars of 84 Salmonella strains and 7 species of non-Salmonella strains were evalua...

Strain subtyping is an important tool for detection of outbreaks caused by Salmonella enterica serotype Enteritidis. Current subtyping methods, however, yield less than optimal subtype discrimination. In this study, we describe the development and evaluation of a multiple-locus variable-number tandem repeat analysis (MLVA) method for subtyping Salmonella serotype Enteritidis. The discrimination...

In the 1990s, Salmonella enterica subsp. enterica serovar Enteritidis has caused 15 outbreaks in Finland; 12 of them were caused by phage type 1 (PT1) and PT4. Thus far, there has been no clear evidence as to the source of these Salmonella Enteritidis PT1 and PT4 strains, so it was necessary to try to characterize them further. Salmonella Enteritidis PT1 (n = 57) and PT4 (n = 43) isolates from ...

background: salmonella is one of the causes of food-borne illnesses worldwide resulting in a wide range of human diseases. the aim of this research was to study molecular epidemiology and antimicrobial resistance of salmonella spp. isolated from resident patients in mazandaran province, northern iran. methods: totally, 51 stool samples were collected from patients in 20 outbreaks recorded in he...

Problem statement: Salmonella infection is a serious medical and veterinary problem worldwide and causes great concern in the human health and food safety. Salmonella enteritidis outer membrane proteins and lipopolysaccharide play important role in the virulence and immunological properties of bacteria. Prophylaxis of enterobacterial infection has proven difficult to achieve. Vaccination is an ...
