Pathogenicity of Antibiotic Resistant/Sensitive Bacteria Vibrio spp. and Aeromonas spp. | Chapter 2 | Theory and Applications of Microbiology and Biotechnology Vol. 3
Bacterial and viral diseases constitute a major factor limiting the successes of shrimp farming industry. In this context, Identification of drug resistant pathogens and determination of the pathogenic processes of shrimp are fundamental for further progress in the disease management. They could be valuable in the evaluation of their epidemiology and control measures. Water samples from the aquaculture environment were contaminated with Vibrio anguillarum, V. damsela, V. furnissii, Aeromonas hydrophila and A. sobria. Both Vibrio spp and Aeromonas spp were shown to be pathogenic and to cause mortality to the infected post larval P. monodon. Vibrio spp. were shown to grow in TCBS agar, zobell’s marine agar and blood agar while Aeromonas spp. additionally exhibited growth in blood agar with selective supplement ampicillin (10 µg/ml) and showed a zone of clearance in DNase agar. LD50 values of V. anguillarim, V. damsela, V. funrissii, A. hydrophila and A. sobria to post larval P. monodo...
