      A survey on the resistance patterns to selected antibiotics of bacterial pathogens of fish and shrimps in Panay Island, Philippines was conducted. One hundred and sixteen (116) bacterial isolates were collected from fish (Chanos chanos, Epinephelus sp. and Lates calcarifer) and shrimp (Penaeus monodon and P. indicus) tissues and rearing water. Among these isolates, only seven were identified as Aeromonas spp., the rest (109 isolates) were Vibrio spp., 42% of which were luminous Vibrio. Results of the sensitivity tests showed that all Aeromonas spp. isolates were resistant to streptomycin, oxytetracycline, and trimethoprim/sulphamethoxazole. Most of the Vibrio spp. isolates (94.5%) were resistant to streptomycin. Multiple resistance to two or more antibiotics was observed in 17 isolates of Vibrio spp. and all isolates of Aeromonas spp.
