Characterization of viable but nonculturable state of .

is an opportunistic bacterial pathogen linked with a range of human diseases. The objective of this study was to investigate the viable but nonculturable (VBNC) state of the bacterium. To induce the VBNC state, cells were maintained in sterilized phosphate-buffered saline at 4°C for three weeks.

Biofilm Formation in : The Role of the Gene.

is a bacterium that inhabits human oral cavities and is an emerging intestinal tract pathogen known to be a biofilm producer and one of the bacterial species found in dental plaque. In this study, biofilms of oral and intestinal isolates were phenotypically characterized. The role of the gene, which is linked to the regulation of biofilm formation in other pathogens, was assessed in relation to the pathogenic potential of this bacterium.

Structural and functional characterization of the cytidine 5'-monophosphate-pseudaminic acid synthase PseF: molecular insight into substrate recognition and catalysis mechanism.

The bacterium is a human gastric pathogen that can cause a wide range of diseases, including chronic gastritis, peptic ulcer and gastric carcinoma. It is classified as a definitive (class I) human carcinogen by the International Agency for Research on Cancer. Flagella-mediated motility is essential for to initiate colonization and for the development of infection in human beings.

Emergence of bla TEM Type Extended-Spectrum β -Lactamase Producing Salmonella spp. in the Urban Area of Bangladesh.

Salmonellosis, an acute invasive enteric infection, is endemic in Bangladesh. We analyzed 128,312 stool samples of diarrheal patients to identify Salmonella spp. during 2005-2013.

Changing trends in the prevalence of Shigella species: emergence of multi-drug resistant Shigella sonnei biotype g in Bangladesh.

Shigellosis, caused by Shigella species, is a major public health problem in Bangladesh. To determine the prevalence and distribution of different Shigella species, we analyzed 10,827 Shigella isolates from patients between 2001 and 2011. S.
