Clostridium perfringens type A isolates producing enterotoxin (CPE) are an
important cause of both food poisoning (FP) and non food borne gastrointestinal
diseases (NFBGID) in both humans and animals. C. perfringens type A food
poisoning is caused by isolates carrying the CPE encoding gene (cpe) on the
chromosome while the...
Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...
Francisella tularensis is a gram-negative facultative intracellular
coccobacillus that primarily infects macrophages. The causative agent of tularemia,
this bacterium is considered among the most infectious organisms known, requiring
fewer than ten organisms to cause disease. Although ubiquitous in nature,
transmission to humans is rare but can occur via insect bites,...
