“…The clinical signs like depression, watery diarrhea, dehydration, ruffled feather, trembling, gasping and emaciation were recorded in E coli infection (Gangane et al, 2006 and Shah et al, 2019) [10,23] . The hematological parameters like Hb, PCV, TEC and TLC in the affected broiler chickens were recorded alterednes as compared to normal values (Umar et al, 2016 and Christie et al, 1999) [27,6] . Myocarditis may be the reason of the increase in AST activity in birds infected with Escherichia coli (Benjamin et al 1998) [5] , whereas the release of this enzyme from the liver as a result of hepatitis is likely the origin of the increase in ALT.…”

The aim of the study was to examine the hematological, serological and Pathomorphological changes in the naturally occurring Colibacillosis in broiler chickens during the period of March to August, 2023 in commercial broiler farms at Ganderbal district of Kashmir. During this study, a total of 200 cases of Colibacillosis were identified at 10 different broiler farms and the dead birds were sent to the Division of Veterinary Pathology for a thorough postmortem investigation. Colibacillosis is a complex disease mainly occurring in the age group of 3-4 week age of age and is characterized by air sacculitis, pericarditis, peritonitis, salpingitis, synovitis, osteomyelitis or yolk sac infection. The pathological changes occurring in Escherichia coli infection were studied in natural cases of avian Colibacillosis. The samples were collected from different poultry farms of Ganderbal district of Kashmir. During postmortem examination, fibrin deposition on the liver and heart, as well as congestion in different organs were observed in the affected birds. The histopathological examination revealed necrosis and the depletion of lymphocytes in the spleen, interstitial pneumonia, fibrinous pericarditis, myocarditis, fibrinous perihepatitis, hepatitis and fatty degeneration in the hepatocytes. It is concluded that the pathogenic E. coli in poultry led to systemic lesions and immunosuppression in birds.

Fatty liver-hemorrhagic syndrome (FLHS) is a common nutritional disease in commercial layers and breeders. The most important clinical sign of FLHS is a sudden drop in egg production and increased mortality which causes significant economic loss in the poultry industry. However, the current diagnostic method for FLHS is based on the gross findings at necropsy which is not helpful to reduce the economic loss because of lateness of diagnosis. Therefore, we need early diagnosis and diagnostic methods before chickens were affected by FLHS. In this study we tried to evaluate the effectiveness of clinical pathology including blood chemistry as an early diagnostic method for FLHS in commercial chickens. Profiles of blood biochemistry were compared between two flocks selected in the same commercial layer farm based on the presence of FLHS clinical sings. A flock with clinical signs of FLHS was designated as FLHS and other flock without clinical signs of FLHS as Non-FLHS. Several parameters of blood biochemistry were selected and compared between FLHS and Non-FLHS to evaluate the possibility of early diagnosis. Average concentrations of serum cholesterol, serum calcium, aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and creatine kinase (CK) were 139.4 ± 87.2 (mg/dL), 24.5 ± 5.4 (mg/dL), 153.6 ± 23.1 (IU/L), 1238.3 ± 475.2 (IU/L) and 1107.3 ± 422.8 (IU/L) in Non-FLHS flock, respectively, and 210.2 ± 173.2 (mg/dL), 25.2 ± 4.1 (mg/dL), 174.3 ± 53.5 (IU/L), 1694.9 ± 691.3 (IU/L) and 1104.9 ± 472.9 (IU/L) in FLHS flock, respectively. The activities of serum cholesterol, AST and LDH except CK, were significantly higher in FLHS than those in Non-FLHS flock (p<0.05). Some birds of FLHS flock showed 2～17 times greater than in Non-FLHS flock. For the definitive diagnosis of FLHS in the flocks tested for blood chemistry, we analyzed fat content and histological lesion score in the liver sampled from both FLHS and Non-FLHS flock. Average liver fat contents based on dry weight were 16.1 ± 0.4 (%) in Non-FLHS flock and were 21.6 ± 16.0 (%) in FLHS flock. These result confirmed that FLHS flock was definitely affected by FLHS. The above results suggest that selected parameters of blood biochemistry, particularly AST, could be useful to diagnose FLHS before significant liver damage occurred in commercial layers.

“…Numerous serogroups of E. coli (1, 2, 3, 6, 8, 15, 18, 35, 71, 74, 78, 87, 88, 95, 103 and 109) have been reported to be pathogenic for poultry (GROSS, 1994) but only a few play an important role in causing disease and are universally distributed (BLANCO et al, 1993). Broiler colisepticaemia is perhaps the most important disease in which E. coli acts as a secondary agent associated with respiratory viruses and mycoplasmas (CHRISTIE and HALLIDAY, 1979).…”

We have carried out an aetiological and pathological study of an outbreak of septicaemia caused by the O165 serogroup of Escherichia coli in Japanese quail (Coturnix coturnix japonica) which resulted in high mortality (90%). After treatment with amoxicilin in drinking water (200 mg/l), morbility and mortality rates dropped markedly. Microbiological studies showed that the organism responsible was an atypical E. coli strain, on the basis of the non-fermentation of lactose (ONPG-), which belonged to the O165 serogroup and was highly virulent for 1-day-old chickens.
