“…The use of the Woo technique is justified, given the occurrence of Trypanosoma evansi in domestic animals at the Bodoquena Plateau, in the Pantanal of the Mato Grosso do Sul and in Bonito Municipality (STEVENS et al, 1989;NUNES et al, 1994;SAVANI et al, 2005), also present in a dog from the rural area of the São Paulo State (COELHO et al, 2013).…”

The study aimed to investigate Leishmania infection in a population of dogs (92 animals) in a fishing area of Bonito Municipality, and evaluate comparatively the serological methods used, immunoenzymatic assay (ELISA), indirect immunofluorescence antibody test (IFAT), and rapid Dual Path-Platform test (DPP®). Blood and aspirate of bone marrow samples were used and parasitological investigation was also performed, such as parasite isolation in Neal, Novy, Nicolle (NNN) medium culture, Woo technique, Giemsa stained smears and specific identification by polymerase chain reaction (PCR). IFAT revealed 56/92 seropositive, the ELISA 8/92 and the DPP®41/92. Regarding the agreement between the serological tests by the Kappa index, there was a slight agreement between ELISA/IFAT and ELISA/DPP®, and fair agreement in IFAT/DPP®. The NNN culture was positive in three out of 21 dogs, and identified by PCR as Leishmania infantum chagasi. No samples were positive by the Woo technique. Our results showed low agreements between the serological tests recommended by the Brazilian Ministry of Heath, and it is necessary to associate other diagnostic techniques, such as parasitological tests and PCR, to increase the sensitivity for canine visceral leishmaniosis diagnosis, mainly regarding asymptomatic dogs in endemic areas.

“…Although some studies have evaluated the dynamics of transmission of T. evansi in dogs from rural areas (Echeverria et al, 2019;Franke et al, 1994;Jaimes-Dueñez et al, 2017a), little is known about it in urban ones where sporadic cases are reported (Coelho et al, 2013;Filgueiras et al, 2019). In the last years an increase in canine trypanosomiasis cases has been recorded by parasitology methods in veterinary diagnostic centers of the Metropolitan Area of Bucaramanga Santander (2018, 0.059% (1/1689) of the diagnosis; 2019, 0.10% (2/1845) of the diagnosis; 2020 0.12% (2/1564) of the diagnosis); 2021, 0.0.21% (4/1875) of the diagnosis, ignoring the presence of T. evansi in these cases (Biovet, 2021).…”

Trypanosoma evansi is a protozoan parasite that is the causative agent of the animal disease known as "surra", which affects a wide variety of wild and domestic mammals including humans. This study aimed to evaluate the molecular point prevalence and clinic-epidemiological traits of T. evansi infection in dogs from municipalities of the Metropolitan Area of Bucaramanga (MAB), Santander, Colombia. From 2019 and 2020, a crosssectional study in four municipalities of MAB was carried out to evaluate the above features in 213 healthy dogs from these cities. Molecular analysis using the primer ESAG/6 and ESAG/7, showed a T. evansi frequency of 1.8% (CI 95% = 0.04-3.68%), while Woo test didn't detect positive animals. A high prevalence of infection was detected in Piedecuesta (10.53%) and Bucaramanga (1.65%), apparently negative animals were detected in Giron and Florida Blanca. Clinical characteristics revealed that all positive animals (4/4) showed low Mean Corpuscular Hemoglobin (MCH) and (3/4) low Mean Corpuscular Volume (MCV), and one animal had a moderate fever with prolonged capillary refill time. The epidemiological characteristics showed that all animals received mixed food, (3/4) came from low socioeconomic areas, and (2/4) from neighborhoods without weekly garbage collection. In conclusion, molecular methods detected a considerable prevalence of animals chronically infected by T. evansi in MAB, with more frequency in neighborhoods of a low socio-economic level where animals have more risk of oral transmission. These results should be considered during urban control programs of surra in MAB.
