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.
鱼类的混合感染是一个常见特征，在这种情况下，细菌、真菌和原生动物等病原体共同存在，导致鱼类健康状况不佳，即所谓的流行性溃疡综合征（EUS）。在这种综合征中，低温和水污染会加重鱼类的感染。在本研究中，发现淡水食用鱼（鳢）感染了名为[具体细菌名称未给出]、[具体细菌名称未给出]和[具体细菌名称未给出]的细菌，还发现了真菌[具体真菌名称未给出]。本研究的主要目的是了解鱼类各个器官中的微生物强度以及对照鱼和感染EUS的鱼的血液学变化。在皮肤中观察到最高微生物载量为8.2±0.12×10⁶ cfu/g，而在胰腺中发现最低载量为3.2±0.8×10⁵ cfu/g。从微生物诊断来看，[具体细菌名称未给出]已从不同器官中分离出来，表明其占主导地位。与对照组相比，感染后的白细胞、平均红细胞体积、淋巴细胞、嗜酸性粒细胞和嗜碱性粒细胞等血液学指标分别增加了17%、16%、5%、58%和27%。研究中鱼类微生物载量的变化可归因于不同鱼类物种之间的摄食习惯、行为和鱼类适应性。这些情况是由环境污染导致的，在本地重污染鱼类中较为严重。因此，结果表明，血红蛋白值、红细胞压积和红细胞数量降低表明在瓦朗加尔发现的感染EUS的鱼存在贫血状况。
