    Abstract

    In February 2000, white spot disease outbreaks occurred among cultured Penaeus monodon in extensive shrimp farms on the southwest coast of India. Bacteria were isolated from infected shrimp that showed reddish body coloration and white spots in the cuticle. The isolates were screened on thiosulfate citrate bile salt sucrose (TCBS) agar plates for the selection of Vibrio species. The primary isolate (QS7) was characterized as V alginolyticus based on morphological, biochemical and physiological characteristics. Antibiotic sensitivity tests of QS7 indicated that the isolate was highly sensitive to chloramphenicol, ciprofloxacin, nalidixic acid and streptomycin. Pathogenicity tests confirmed that the isolate was virulent for P. monodon. Based on the lethal dose (LD,,) value (5 x 10"fu per shrimp), it was inferred that shrimp weakened by white spot syndrome virus would succumb to secondary infection by QS7
