Description 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
