Abstract:
Background: Shigella species are the leading cause of human shigellosis. In Zambia, more than 30% of children experiencing diarrhea are infected with Shigella species. The increasing resistance of Shigella species to the recommended therapy is of great concern. Therefore, this study investigated the antibiotic resistance profiles and phenotypic and genotypic characteristics of Shigella isolates at the largest referral hospital in Zambia. Methodology: Of the forty-eight archived presumptive Shigella isolates, thirty-two were serologically confirmed and subjected to antimicrobial susceptibility

Abstract:
Shigella causes moderate to severe diarrhea or dysentery after invading the colon mucosa. Long Pentraxin 3 (PTX3) is recognized as the humoral component of the innate immune response to bacterial pathogens. We examined the interplay between levels of PTX3 and levels of anti-Shigella lipopolysaccharide (LPS) and anti-Shigella type 3 secretion system protein-IpaB antibodies in children during acute shigellosis and after recovery. PTX3 concentrations in serum and stool extracts were determined by sandwich ELISA using commercial anti-PTX3 antibodies. Serum IgG, IgM, and IgA anti-S. sonnei LPS or a

Abstract Here, we report a novel virulent P2-like bacteriophage, R18C, isolated from rabbit faeces, which, in addition to Escherichia coli K-12 strains, was able to be propagated on Citrobacter rodentium strain ICC169 and a range of Shigella sonnei strains with high efficiency of plating (EOP). It represents the first lytic bacteriophage originating from rabbit and the first infectious P2-like phage of animal origin. In the three characteristic moron-containing regions of P2-like phages, R18C contains genes with unknown function that have so far only been found in cryptic P2-like prophages.

SUMMARYIn Greece the public health surveillance for most infectious diseases, including shigellosis, is not well developed. However, four waterborne outbreaks of shigellosis have been recorded in Greece in the last three decades, in different areas of the country, under different environmental and socioeconomic conditions. This study presents the epidemiological characteristics of these four outbreaks in order to examine common points and differences and to investigate their possible association with environmental and socioeconomic conditions.
