“…Roberts et al (1989) carried out a survey of the ulcerative disease in Bangladesh where A. hydrophila and A. sobria were found to be the dominant bacteria in the EUS lesions and ulcers. Pal and Pradhan (1990) carried out a study on the bacterial involvement in ulcerative condition of air-breathing catfish in India and isolated four types of bacteria, two of which were fluorescent pseudomonads, one aeromonad (A. hydrophila) and one coccus (Micrococcus varians) from skin lesions of the fish. Chowdhury et al (2002) observed the severity of the ulcerative disease in different fishes with concurrent infection of Aphanomyces invadans and Aeromonas bacteria.…”

Aeromonas hydrophila bacteria was isolated from the suspected EUS-affected shing fish, Heteropneustes fossilis (Bloch). The disease investigations were primarily based on clinical signs and subsequently confirmed by the isolation of bacterial pathogen Aeromonas hydrophila from lesion of liver and kidney. The A. hydrophila isolates were identified by a series of morphological, physiological and biochemical tests. The total bacterial load in liver, intestine and kidney were 1.67 × 10 4 to 6.46 × 10 8 CFU/g, 1.71 × 10 3 to 1.18 × 10 9 CFU/g and 1.47 × 10 4 to 3.70 × 10 8 CFU/g respectively.

“…And also the present investigation deals with the comparison of blood parameters with special reference to the microbial flora of fresh water fish of Channa punctatus infected and control fish. In the EUS affected murrels captured from the wild, different pathogenic organisms including Fungi, A. invadans, (Chinabut 1995), bacteria A. hydrophila, Vibrio sp., (Pal and Pradhan 1990) and Virus (Frerichs 1995) have been detected. Among the fish potential pathogens were identified, Aeromonas and pseudomonas species pose the most significant threats to murrel fishes.…”

“…Aeromonas hydrophila is also found with this fungi (Karunasagar et al 1995). These pathogens seize the blood circulation and resulting edema of the abdominal cavity (Pal and Pradhan 1990). The epithelial layer of the skin, gills and alimentary tract, confer potential sites for these pathogens (Gobinath and Ravichandran 2011).…”

The mixed infection in fishes is a common feature and in this Pathogens like Bacteria, Fungi and Protozoan's are found together to cause ill health to the fishes known as Epizootic Ulcerative Syndrome (EUS). In this syndrome the low temperature and aquatic pollution aggravates the infection in fishes. In the present study the fresh water edible fish, (Murrel) was found infected with the bacteria namely,, and The fungi, was also found. The major objective of this study is to understand the microbial intensity in various organs of fish and hematological variations in both control and EUS infected fish. The highest microbial load of 8.2 ± 0.12 × 10 cfu gwas observed in the skin where as the lowest load of 3.2 ± 0.8 × 10 cfu g was found in the pancreas. From the microbial diagnosis, has been isolated from different organs indicating its predominant presence. In comparison with the control the haemotological indices like WBC, MCV, Lymophocytes, Eosinophils and Basophils were found increased in the infected by (17 %), (16 %), (5 %), (58 %) and (27 %) respectively. The variations in microbial load found in fish in the study can be attributed to feeding habits, behavior, fish adaptations among the different fish species. These conditions are being caused by the presence of environmental pollution and are high in heavy native fishes. Thus the results showed that low of Haemoglobin value Packed Cell Volume and Red Blood Corpuscles indicated the presence of anemic conditions in the EUS infected fish found in Warangal.
