Salmonella Derby Clonal Spread from Pork
The genetic diversity of the Derby serotype of Salmonella enterica in Spain was examined by pulsed-field gel electrophoresis (PFGE). Out of 24 identified PFGE profiles, a major clone was detected in 19% of strains from humans, 52% from food, and 62% from swine. This clone (clone 1) was isolated from pork products, suggesting swine as its source.
متن کاملRecovery of Salmonella from commercial shell eggs by shell rinse and shell crush methodologies.
Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush...
متن کاملSalmonella derby cross-protection study.
An avirulent live (AVL), Salmonella choleraesuis vaccine (Salmo Shield Live [Grand Laboratories, Inc.]) was administered to pigs at weaning or 3 weeks of age. Two weeks after vaccination the vaccinated pigs as well as unvaccinated control pigs were challenged intranasally with a commonly isolated environmental Salmonella serotype, S. derby. At 2, 4, and 6 weeks after challenge, pigs were euthan...
متن کاملDetection of Salmonella in Egg Shell and Egg Content from Different Housing Systems for Laying Hens
Polymerase chain reaction (PCR) assay and conventional microbiological methods were used to detect bacterial contamination of egg shells and egg content in different commercial housing systems, open house system and evaporative cooling system. A PCR assay was developed for direct detection using a set of primers specific for the invasion by A gene (invA) of Salmonella spp. PCR detected the pres...
متن کاملDetection and characterization of variant Salmonella genomic island 1s from Salmonella Derby isolates.
The purpose of this study is to investigate the distribution and structure of Salmonella genomic island 1 (SGI1) among Salmonella enterica serovar Derby isolates from swine and their rearing environment. Three variants of SGI1s, specifically SGI1-A, C, and I, were identified by PCR mapping. The results of macro-restriction analysis and DNA sequencing of SGI1 flanking regions revealed that there...
