Suicide phenomenon in mesophilic aeromonads as a basis for species identification.
The acetic acid-mediated suicide phenomenon in mesophilic aeromonads in conjunction with tests for aerogenicity and esculin hydrolysis served as the basis for species identification. Of 210 Aeromonas isolates tested at 30 degrees C, 88 were identified as Aeromonas hydrophila (nonsuicidal, aerogenic, esculin positive), 52 were identified as A. sobria (suicide variable, aerogenic, esculin negativ...
متن کاملANTIBIOTIC RESISTANT MOTILE AEROMONADS INDUCED SEPTICEMIA IN PHILIPPINE CATFISH Clarias batrachus (Linnaeus, 1758) FINGERLINGS
Philippine catfish, Clarias batrachus farming is receiving much attention in recent years so also the diseases in catfish aquaculture. During the disease surveillance in catfish farms, mortalities were observed in C. batrachus fingerlings in a nursery and this report describes the bacteriological and histopathological observations made on the diseased catfish. The gross and clinical signs obser...
متن کاملCharacterization and antimicrobial susceptibility of motile aeromonads isolated from freshwater ornamental fish showing signs of septicaemia.
A total of 74 phenotypically identified presumptive motile Aeromonas isolates recovered from septicaemic freshwater ornamental fish in Sri Lanka were genetically characterized by sequencing of rpoD and gyrB genes. rpoD/gyrB phylogeny confirmed only 53 isolates as Aeromonas, among which A. veronii was the predominant species (79.2%), followed by A. hydrophila (7.5%), A. caviae (5.7%), A. jandaei...
متن کاملPhenotypic and genetic diversity of motile aeromonads isolated from diseased fish and fish farms
Samples from the kidney of 100 diseased fish with signs of haemorrhagic septicemia and 50 samples from outlet water of fish farms were taken aseptically and cultured. In the laboratory, 75 colonies of gram-negative bacteria were biochemically diagnosed as motile aeromonads in our Bacteriology Laboratory Unit using API 20E rapid identification system. The genotype identification using specific p...
متن کاملAntibiotic resistance pattern of motile aeromonads from farm raised fresh water fish.
Motile aeromonads isolated from the intestines of farm-raised freshwater fish such as Catla catla, Labeo rohita and Ctenopharyngodon idella have been characterized to species level. Morphological and physiological grouping revealed 61% Aeromonas hydrophila, 30% Aeromonas caviae, 7% Aeromonas sobria and 2% which remained unidentified. Hemolytic activity was detected mostly in A. hydrophila, whil...
