Seroprevalencia de fiebre Q y factores de riesgo asociados a la infección en porcinos del cantón Macará, provincia de Loja

Q Fever is a global zoonotic disease caused by the bacterium Coxiella burnetii, ruminants are considered the main reservoir, however the presence of the bacteria has also been found in other farm animals and pets. This study was performed in the Macará canton, province of Loja, because it is a border transit zone and commercial exchange, particularly in pig production areas. The objectives were to determine the seroprevalence of Q Fever and the factors associated with the disease. Data was collected through an epidemiological survey and blood samples from 150 pigs from Macará, Eloy Alfaro, and Larama, towns. The serological analysis was conducted using the commercial enzyme-linked immunosorbent assay (ELISA). The results showed a 0% seroprevalence of Q Fever infection in pigs, indicating a negative health status for this disease. Epidemiological data were processed, and the sanitary management carried out by the producers was characterized. The majority of animals were female (65.33%), and 77.33% were fattening pigs. Of the farms, 80% were privately owned; 96.67% practiced natural breeding. Other animals such as goats, cattle, poultry, and pets were present on 70% and 66.67% of the farms, respectively. The farms had technical support; however, none of them implemented biosecurity measures. Moreover, 96.67% of the farms disposed of solid waste in the pastures, while 100% disposed of liquid waste into rivers and streams. It was concluded that there is no seroprevalence of Q Fever due to the presence of Coxiella burnetii in pigs in the canton of Macará, province of Loja, and that the sanitary and management conditions are insufficient to prevent the presence of diseases.
