Concurrent Infection of Gastro-Intestinal Parasites and Bacteria Associated with Diarrhea in Bengal Goats in Bangladesh

Hundred diarrhoeic kids' faecal samples were examined of which 64% and 98% kids are affected with parasites and bacteria respectively. Around 59.7% and 61.22% had single, 31.34% and 37.76% had dual and only 4.48% and 1.02% had triple concurrent infection respectively in parasite and bacteria associated diarrhoeic kids. Analysis of the results of bacterio-parasitic enteropathogens revealed that highest percentage (64%) kids were infected with concurrent parasitic and bacterial infection but the faecal samples of four diarrhoeic kids showed negative for both bacteria and parasitic infections. Highest of gastro-intestinal nematodes (GIN) infection (48%) was recorded in kids followed by Eimeria sp. (27%), Toxocara vitulorum (14%) and lowest (1%) with each of the Strongyloides sp., Paramphistomum sp. and Moniezia sp. The clinical Toxocara vitulorum infection first recorded at the first of 15 days, GIN at 30 days, Strongyloides sp. at 45 days, Paramphistomum sp. at 150 days and Eimeria sp. infection at 25 days. Similarly, the rate of Bacillus infection (87%), was found highest followed by Escherichia coli (37%), Staphylococcus (9%), and lowest of Salmonella (5%) infection. Although Bacillus and E. coli recorded first time at 10 days and Staphylococcus at 30 days of age but Salmonella was recorded at the age of 60. A characteristic age specific prevalence of both parasitic and bacterial enteropathogens was observed and it was found that the severity of infection was increasing with age for both parasitic and bacterial infection and the ratio of all the infections were almost similar.
