R. A.  aFactors associated with the seroprevalence of caseous lymphadenitis in sheep from Northeastern Brazil.h[electronic resource]  c2020  aAbstract: Caseous lymphadenitis (CL) is one of the main infectious diseases in sheep, responsible for great economic losses, mainly in Northeast region of Brazil, which has the largest sheep flock in the country. Thus, the aim of this survey was to determine the factors associated with the seroprevalence of this disease in sheep from Northeastern Brazil using a planned sample of flocks and animals. Samples were collected from 2312 adult and young sheep of both sex from 196 farms, located in 51 municipalities in five Northeastern Brazilian states (Ceará, Paraíba, Piauí, Rio Grande do Norte, and Sergipe). Serological diagnosis was performed using the indirect ELISA technique. Factors associated with seropositivity were identified by variables extracted from epidemiological questionnaires administered to breeders, using univariable and multivariable analyses. Factors associated with prevalence were purebred sheep (Prevalence ratio - PR = 1.189; P = 0.017), ram acquisition from animal expositions (PR = 1.192; P = 0.020), offspring is separated from ewes (PR = 1.132; P = 0.048), water supplied to sheep from ponds (PR = 1.365; P = 0.002), and delayed disposal of infected animals (PR = 1.263; P = 0.027). Flock-level and animal-level prevalences were 93.88 % (95 % CI = 89.60?96.46%) and 37.46 % (95 % CI = 35.51?39.45%), respectively. In view of the high prevalence found here and based on the associated factors, the implementation of an efficient CL control programme in Northeastern Brazil is recommended.  aBacterial infections  aEpidemiology  aMycobacterial diseases  aSheep diseases  aBactéria  aCorynebacterium Pseudotuberculosis  aDoença Animal  aLinfadenite Caseosa  aOvino  aBacterial pathogens  aHigh prevalence  aIndirect ELISA  aNortheastern Brazil  aSoroprevalência1 aFARIAS, A.
