Outbreak of Parasitic Dinoflagellate sp. Infection in an Endangered Fish from India: Arulius Barb ().

Freshwater velvet disease is caused by the dinoflagellate parasite, sp. This parasite has been reported in tropical and subtropical fishes, and it can cause devastating losses. Moreover, sp.

Bioactives of microbes isolated from Western Ghat belt of Kerala show β-lactamase inhibition along with wide spectrum antimicrobial activity.

The present study describes the exploitation of microbial biodiversity from Western Ghats of Kerala for screening of bioactives having β-lactamase inhibitory activities. A total of 700 pure cultures were isolated and were screened for antibacterial activity against a β-lactam resistant Bacillus cereus strain (PL 10) isolated from the same niche. Bioactive extracts made from 45 isolates showed inhibitory activities against PL 10, of which two strains showed inhibition of extended spectrum β-lactamase (ESBL) producing Klebsiella ESBL1101 and three strains inhibited methicillin-resistant Staphylococcus aureus (MRSA) strain MRSA831.
