“…The Icterohaemorrhagiae serogroup was identified as the most frequent serogroup in other studies on equids (BEZERRA et al, 2010;DIAS et al, 2015;ESQUIVEL et al, 2018); it is considered the most prevalent serogroup in the species and responsible for most infections in humans (BARBOSA NETA et al, 2016). Infection by this serogroup is associated with the presence of rodents and exposure to contaminated urine from these animals (HAMOND, 2012), facilitated by the extensive breeding of donkeys in this study.…”

“…The positivity rate for leptospirosis obtained in studies on animals destined for traction in large urban centers is higher than that found in our study with animals kept in rural areas. Bezerra et al (2010) found an 85% seropositivity rate in donkeys from São Luís, Maranhão, and Dias et al (2015) found a 75% seropositivity rate in equids from Belém, Pará. The high rate found in these studies can be explained by the intense and disordered urbanization associated with the rapid growth of the capitals, lack of basic sanitation, and inadequate management of refuse that provides favorable environmental conditions for the reproduction of rodents, the main reservoirs of the agent (GUIMARÃES et al, 2014).…”

Brazil is the eighth largest exporter of equidae meat in the world. Most donkey meat is obtained from discarded animals, raising concerns about their health status, particularly regarding zoonotic infections such as leptospirosis. Thus, this study aimed to determine the frequency of anti-Leptospira sp. antibodies in Northeastern donkeys at two properties specializing in producing donkeys for slaughter and export to the Chinese market, in the municipalities of Parnamirim (A) and Araripina (B), both located in the mesoregion of the Sertão of Pernambuco, Northeastern Brazil. The serum of 349 donkeys was collected, including 147 males and 202 females, aged 3 to 12 years. All animals were subjected to the Microscopic Agglutination Test (MAT) using a cut-off point of 1:50. A total of 19.8% seropositive animals were obtained. The Icterohaemorrhagiae serogroup was the most found in this study (40.6%), followed by Australis (27.5%), Autumnalis (8.7%), Sejroe (8.7%), Pomona (8.7%), Celledoni (2.9%), and Tarassovi (2.9%). A higher overall rate of seropositivity was found in donkeys from property B (2.2.4%) in the municipality of Araripina. In the association analysis, it was observed that animals less than 9 years of age were more likely to be seropositive, this may be due to the acquisition of resistance to Leptospira sp. as age advances. A significant number of donkeys seropositive for Leptospira sp. was found, thus, breeding these animals for slaughter and export requires implementing prophylactic measures.

“…The Icterohaemorrhagiae serogroup, the second most frequent in this study (29.3%), has been widely reported in horses in tropical areas (Lasta et al, 2013;Teixeira et al, 2014;Dias et al, 2015) and is one of the main groups responsible for infections in humans (Oliveira et al, 2017;Polo et al, 2019). The serogroup stands out because of its high prevalence in equines in Brazil, especially in studies conducted in high density demographic regions and/or coastal areas (Teixeira et al, 2014;Dias et al, 2015).…”

Considering the importance of leptospirosis in both equine husbandry and public health, as well as the relevance of knowledge of current serogroup and the small number of studies addressing this disease in equines in Northeastern Brazil, the present study performed a serological survey of Leptospira spp. in a serum bank of 1,267 equines originating from 177 municipalities, located in four states in Northeastern Brazil: Ceará, Rio Grande do Norte, Paraíba and Pernambuco. The microscopic agglutination test (MAT) was used for diagnosis of leptospirosis using 24 serovars as antigens. The frequency of reagent equines was 29.7% (376/1,267), and 68.9% (122/177) of municipalities had at least one positive reaction. The serogroups reagent were Australis (37.2%), Icterohaemorrhagiae (29.3%), Tarassovi (9.6%), Sejroe (5.8%), Pomona (5.3%), Grippotyphosa (4.5%), Pyrogenes (2.4%), Bataviae (1.9%), Ballum and Hebdomadis (1.3%), Mini (0.5%), Celledoni, Shermani, and Javanica (0.3% each). There were significant statistical differences regarding sex and age, with a higher frequency in females (P= 0.014), and in animals ≥ 6 years (P=0.001). We concluded that seropositivity to Leptospira spp. is high in equines in Northeastern Brazil, with a predominance of serologic reactions to the Australis serogroup in the border areas between the states, and the Icterohaemorrhagiae serogroup in coastal areas or their vicinity. The high degree of seropositivity found points to the need to implement prophylactic strategies, both intraspecies infection prophylaxis and rodent control. We also recommended avoiding animal crowding and separating animals according to sex and age group during handling.

“…Em relação à pesquisa de anticorpos anti-Leptospira spp., a reatividade encontrada no presente estudo está dentro da faixa de frequência encontrada por outros autores, que variaram entre 23,07 e 100% de equinos soro-reagentes para os mais diversificados sorovares (Moraes et al, 2010;Finger et al, 2014;Dias et al, 2015;Pinho et al, 2014;Alves et al, 2016).…”

Pesquisa de anticorpos contra Leptospira spp. e Brucella lisa foi realizada em equinos da raça Marajoara e Puruca provenientes da Ilha do Marajó. Utilizaram-se 57 amostras de soro de equinos de ambos os sexos, diferentes idades e sem sintomatologia clínica de doença causada pelos agentes pesquisados. As amostras forma submetidas ao teste de aglutinação microscópica (MAT) para pesquisa de Leptospira spp. e teste de soroaglutinação rápida em placa com antígeno acidificado tamponado (AAT) para pesquisa de Brucella spp. Dos 57 soros avaliados, 49,1% (28/57) foram reagentes para um ou mais sorovares, apresentando-se quatro coaglutinações. Os sorogrupos mais frequen-temente encontrados no presente estudo foram Grippotyphosa, Djasiman, Serjoe, Icterohaemorrhagiae, Shermani e Cynopteri, com títulos entre 100 e 3200. Nenhum animal foi reagente na pesquisa de aglutininas contra brucelose. Conclui-se que os animais alvos do estudo estiveram expostos à Leptospira spp., mas não demonstraram sorologicamente ter infectado-se por Brucella.
