Sequence variation in the thermostable direct hemolysin-related hemolysin (trh) gene of Vibrio parahaemolyticus
Article Abstract:
The nucleotide sequence manifesting very weak hybridization signals to the trh probe in some strains of Vibrio parahaemolyticus was sequenced and its product analyzed. A new gene, named trh2 was noted, and its product was found to be a hemolytic protein whose specificities were different from the hemolysin coded for by the trh, now called trh1, gene. Hybridization analysis showed significant strain-to-strain variations for both genes. The trh2 gene was detected in a significant number of clinical strains, hence strains with this gene are to be considered potentially virulent.

Novel Bacillus thuringiensis insecticidal crystal protein with a silent activity against coleopteran larvae
Article Abstract:
A protein called CryIIIC produced by Bacillus thuringiensis was found to have silent activity against Colorado potato beetle larvae. The protein is contained in bipyramidal crystals and is made up of a single chain with a trypsin-resistant toxic core moiety of 72 kDa. Insecticidal activity is expressed only after in vitro solubilization and proteolytic activation. The native crystals are nontoxic. The gene coding for CryIIIC was also sequenced. Relatively low homology was found between CryIIIC and the other Cry proteins.

Shigella dysentriae type 1- specific bacteriophage from environmental waters in Bangladesh
Article Abstract:
A bacteriophage from surface water samples from Bangladesh that specifically lyses strains of S. dysenteriae type 1 was isolated. The results of the study suggest that phage SF-9 may have epidemiological applications in tracing the presence of S. dysenteriae type 1 in environmental waters.
