Retrospective Epidemiological Study And Clinico Serological Observations On Haemorrhagic Septicaemia In Cattle And Buffaloes In District Dera Ghazi Khan During 1996 - 1998

An active surveillance was conducted to understand the incidence and economic losses due to Haemorrhagic septicaemia in randomly selected 10 villages of tehsil/district Dera Ghazi Khan. The informations about the morbidity, mortality and case fatality rates
related to HS were collected on a prescribed questionnaire during the previous year.

The data of 4248 animals from the affected villages was cllected which included 2963 buffaloes (1042 young and 1921 adult) and 1285 cattle (417 young and 868 adults). The morbidity, mortality and case fatality rates were 22.3%, 19.64% and 88.04% in buffaloes (with 57.58%, 52.30% and 90.83% in young and 3.17%, 1.92% and 60.65% in adult animals) and 6.07%, 3.19% and 52.56% in cattle (with 8.63%, 5.27% and 61.11% in young and 4.83%, 2.18% and 45.23% in adult animals) respectively.

The clinical signs observed were body temperature 104-107°F (17.39%), respiratory distress (14.61%), salivation (14.54%), nasal discharge (9.67%) and edema around throat (9.34%).

The average total serum protein, serum albumin and serum globulin of diseased buffalo were 4.99g/dl, 2.60g/dl and 2.42g/dl while in diseased cattle the values were 5.78g/dl, 2.47g/dl and 2.35g/dl.

Indirect haemagglutination test (IHA) used for the antibody detection against H.S. revealed that the GMT of diseased buffaloes and cattle was lower than that of healthy animals. No carrier buffalo and cattle could be detected by nasopharyngeal swabs.

Economic losses due to haemorrhagic septicaemia have been estimated to be Rs. 2.615 million per annum.
