Abstract
The study aimed to determine the prevalence of Ancylostoma spp. in dogs raised in Hue City and measure the efficacy of ivermectin. A total of 182 fecal samples from dogs were collected and tested by flotation technique. Univariate binary logistic regression was used to compute the odds ratio associated with potential risk factors. The result showed that the overall prevalence of Ancylostoma spp. in Hue City was 19.78%. No significant associations were observed among breed, age, sex and breeding method for Ancylostoma spp. (p>0.05). There was an association between Ancylostoma spp. infection and regular deworming in dogs (p<0.05). Regularly dewormed dogs had a lower infection rate (12.61%) than dogs that were not regularly dewormed (33.33%) (p<0.05). Ivermectin was highly effective in treating Ancylostoma spp., and 88% (22/25) of dogs were negative stool samples 10 days after treatment.
Tóm tắt
Nghiên cứu được thực hiện nhằm xác định tỷ lệ nhiễm Ancylostoma spp. ở chó tại thành phố Huế và sự mẫn cảm của mầm bệnh với thuốc ivermectin. Mẫu phân chó được thu thập với số lượng 182 mẫu và được xét nghiệm bằng phương pháp phù nổi. Phân tích hồi quy nhị phân đơn biến được thực hiện để xác định tỷ suất chênh OR của các yếu tố có thể liên quan đến ancylostomiasis. Kết quả cho thấy tỷ lệ nhiễm Ancylostoma spp. là 19,78%. Các yếu tố bao gồm giống, tuổi, tính biệt và phương thức nuôi không ảnh hưởng đến tỷ lệ nhiễm mầm bệnh. Trong khi đó, chó được tẩy giun thường xuyên có tỷ lệ nhiễm (12,61%) thấp hơn nhóm chó không được tẩy giun định kỳ (33,33%) (p<0,05). Thuốc ivermectin cho hiệu quả điều trị cao đối với giun móc, 88% (22/25) chó có mẫu phân âm tính sau 10 ngày kể từ thời điểm điều trị.
