AIMS To speciate Campylobacter strains from the caeca of chickens in Grenada using PCR and to evaluate DNA-based typing methods for the characterization of these isolates. METHODS AND RESULTS Isolates were speciated with two multiplex PCR assays and were typed with flaA-RFLP, pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST).(More)
AIMS Thirty Campylobacter jejuni strains isolated from fecal samples (n = 94; 32%) from 13 positive farms (n = 17; 76%) from commercial broiler chickens in Puerto Rico were analysed by molecular methods. METHODS AND RESULTS Isolates were identified with multiplex polymerase chain reaction assays, tested for their antimicrobial susceptibility and(More)
AIMS A Portable Multi-use Automated Concentration System (PMACS) concentrates micro-organisms from large volumes of water through automated dead-end ultrafiltration and backflushing. The ability to detect microbial targets from ground, surface and cooling tower waters collected using standard methods was compared with samples from the PMACS in this study.(More)
Accurate identification and optimal culturing procedures for Campylobacter spp. from live broilers are needed for epidemiological studies. Because there is no standardized protocol, we designed and conducted studies to evaluate different selective media for the culturing and isolation of Campylobacter spp. from cecal and fecal samples obtained from(More)
(-)-Epigallocatechin 3-O-gallate (EGCG) a molecule found in green tea and known for a plethora of bioactive properties is an inhibitor of heat shock protein 90 (HSP90), a protein of interest as a target for cancer and neuroprotection. Determination of the spectral properties of EGCG fluorescence in environments similar to those of binding sites found in(More)
Clostridium colinum is the causative agent of ulcerative enteritis, a serious disease of the bobwhite quail (Colinus virginianus) and sporadically of young chickens. The aim of the present study was to develop a polymerase chain reaction (PCR) assay specific for C. colinum identification. The 16S rDNA sequence of C. colinum was analysed and two(More)
