Cultivation of on new cheap monoxenic media without peptone.

The study of species biodiversity within the genus of nematodes would be facilitated by the isolation of as many species as possible. So far, over 50 species have been found, usually associated with decaying vegetation or soil samples, with many from Africa, South America and Southeast Asia. Scientists based in these regions can contribute to sampling and their proximity would allow intensive sampling, which would be useful for understanding the natural history of these species.

Type III Secretion Effector VopQ of Vibrio parahaemolyticus Modulates Central Carbon Metabolism in Epithelial Cells.

is a Gram-negative halophilic pathogen that frequently causes acute gastroenteritis and occasional wound infection. contains several virulence factors, including type III secretion systems (T3SSs) and thermostable direct hemolysin (TDH). In particular, T3SS1 is a potent cytotoxic inducer, and T3SS2 is essential for causing acute gastroenteritis.

Potential transmission opportunity of CTX-M-producing Escherichia coli on a large-scale chicken farm in Vietnam.

Objectives: Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli have disseminated worldwide. This study investigated bla-positive E. coli on a large-scale Vietnamese chicken farm and analysed whether there was any difference in prevalence and molecular characteristics of bla-positive E.

Carriage of Escherichia coli Producing CTX-M-Type Extended-Spectrum β-Lactamase in Healthy Vietnamese Individuals.

Healthy carriage of CTX-M-type extended-spectrum β-lactamase (ESBL)-producing Escherichia coli was examined by thrice collecting fecal samples from the same 199 healthy Vietnamese subjects every 6 months. Using pulsed-field gel electrophoresis (PFGE), identical PFGE patterns throughout the three samplings were not observed, although prevalence of E. coli in the subjects was around 50% in the three samplings.
