[Prevalence of canine Leishmania infections in Xin'an County, Luoyang City in 2020].
Objective: To investigate the prevalence of canine Leishmania infections in villages endemic for visceral leishmaniasis in Xin'an County, Luoyang City, so as to provide insights into visceral leishmaniasis prevention and control.
Methods: All dogs were captured from Huzhanggou Village, Xin'an County, Luoyang City in August 2020, where local cases with visceral leishmaniasis lived. The basic characteristics of dogs were collected, and venous blood was collected via the ear or neck veins of dogs. The serum anti-Leishmania antibody was detected using the rk39 immunochromatographic test and Leishmania nucleic acid was detected using PCR assay, and the prevalence of Leishmania infection was estimated in dogs.
Results: A total of 133 domestic dogs were captured from Huzhanggou Village, with a median age of 18.0 (28.5) months. The sero-prevalence of anti-Leishmania antibody was 24.81% (33/133) and the prevalence of a positive PCR assay was 14.29% (19/133) in dogs. The median ages of Leishmania-infected and uninfected dogs were 24.0 (36.0) months and 12.0 (18.0) months, respectively (U = 872.000, P = 0.000), and the prevalence of Leishmania infection was 55.56% (5/9) in "mangy dogs" and 24.19% (30/124) in asymptomatic dogs (χ2 = 2.793, P = 0.095).
Conclusions: There are a large number of asymptomatic dogs with Leishmania infections in Xin'an County, Luoyang City, with a high transmission risk of visceral leishmaniasis. Timely prevention and control measures are required to control the spread of visceral leishmaniasis.
