Study on the prevalence of roundworm infection in the gastrointestinal tract in cats and dogs in Viet Yen district, Bac Giang province
To advise farmers to see the risk of humans being infected with parasitic roundworms in dogs and cats. Thereby raising awareness for breeders about effective diagnosis, prevention, and treatment of diseases in dogs and cats, contributing to protecting public health. We investigated and determined some characteristics of the infection rate of roundworm species in domesticated dogs and cats in Viet Yen district, Bac Giang province from August 2021 to May 2022. Random sampling and multi-level cluster sampling were used in this study to collect dogs' and cats’ feces samples. Next, Wisconsin sugar centrifugal floatation technique and McMaster egg counting method were applied to examine and identify roundworm eggs in the feces. Research results on 423 samples of dog and cat feces collected in 6 communes of Viet Yen district (Viet Tien, Huong Mai, Tu Lan, Minh Duc, Quang Minh, and Bich Dong town), Bac Giang province showed that the overall prevalence of gastrointestinal roundworm infection in dogs is 43.56%. That rate in cats is 39.90%, with diagnostic results by the sugar floatation technique. Based on the morphology and size of roundworm eggs, 3 species of roundworms parasitic in the intestinal tract of dogs and 2 species in the intestinal tract of cats were detected. Under 2-month-old dogs and cats have the highest gastrointestinal roundworm infections. Domestic cats and dogs have a higher rate of roundworm infection than other breeds. Dogs and cats raised by free-range farming have the highest rate of gastrointestinal roundworm infection.
