Detecção De Anticorpos Para Leptospira Spp. Em Animais E Funcionários Do Zoológico Municipal De Uberaba, Mg

Abstract

RESUMO O presente estudo teve como objetivo detectar anticorpos contra Leptospira spp. pelo teste de soroaglutinação microscópica em animais e funcionários do Zoológico Municipal de Uberaba, MG. Foram colhidas amostras de sangue de 166 animais entre mamíferos, répteis, peixes e aves e dos 36 funcionários. Dos animais estudados, 17 (10,24%) foram reagentes para anticorpos contra Leptospira spp. Os sorovares encontrados nas diferentes espécies foram: Grippotyphosa em uma espécie Cerdocyon thous (Cachorro-do-mato); Canicola em uma espécie Chrysocyon brachiurus (Lobo-Guará); Andamana e Icterohaemorrhagiae em duas espécies Leopardus pardalis(Jaguatirica); Canicola e Icterohaemorrhagiae em duas espécies Puma concolor (Suçuarana); Icterohaemorrhagiae em duas espécies Tayassu tajacu (Cateto); Andamana em duas espécies Geochelone spp. (Jabuti); Patoc em uma espécie Trachemys scripta (Tigre d’água); Canicola em seis espécies Oreochromis niloticus (Tilápia); Icterohaemorrhagiae em uma espécie Rattus rattus (Rato de telhado). Os sorovares mais freqüentes foram Canicola 8 (47,05%); Icterohaemorrhagiae 5 (29,41%) e Andamana 2 (11,76%). O título 100 foi o mais prevalente com 35,3% entre as espécies reagentes. As aves os gatos domésticos errantes e os funcionários do zoológico foram negativos para os sorovares analisados. Dentre as espécies estudadas, os mamíferos e os peixes apresentaram maior sororeatividade. Destaca-se a importância de mais estudos em animais silvestres e em de cativeiro e sua relevância no contexto da epidemiologia da Leptospirose.

Incidence of leptospirosis in non-human primates at the santarém zoo, Pará, Brazil

“…A similar study was carried out in Aracaju-Sergipe where it found positive primates for Leptospira, of the 18 primates analyzed 2 (11.1%) were positive for leptospirosis, and reports that shows the serovar Icterohaemorragiae is found in synatropic rodents as maintenance hosts, as well demonstrating that other species may have participated in the epidemiological chain of this sip (Pimentel et al, 2009). The rodents end up spreading the serovar through the urine and thus affecting other species of animals (Esteves, Neto, Girio, Vergara, & Carvalho, 2005;Murillo et al, 2020;Piredda et al, 2023), but another study shows that these rodents, as they are not a common part of this environment, can circulate at night and thus contaminate animals, which may explain its occurrence in the studied primates (Chuma et al, 2020;Ferreira et al, 2011;Rajeev et al, 2020). Among the studies carried out with primates using SAM as a diagnostic method, there is a study in the state of Tocantins in 2002 where a search for antibodies against Leptospira was carried out with 286 blood samples Cebus apella (capuchin monkey).…”

“…In the primate order, the distribution and occurrence of anti-Leptospira antibodies have already been identified in some studies and these findings showed that primates are exposed to several Leptospira serovars, but research on the epidemiology of leptospirosis in free-living primates is still scarce, considering the diversity of primates existing in Brazil (dos Esteves et al, 2005;Gonçalves et al, 2021). From research related to the most relevant studies in the literature on the topic, it can be inferred that the low incidence of leptospirosis in nature is associated with the behavior and arboreal habits of neotropical primates (Oliveira et al, 2013;Reid, Herron, Hines, Orchard, & Altman, 1993;Wilson et al, 2021).…”

Rescue and rehabilitation of maned wolf (Chrysocyon brachyurus) in Paraguay: Case description

“…Lowering the cut‐off titre could result in false positives, and taking a higher cut‐off titre would result in a reduction of serovars detected (Grimm et al., 2020). Up to five serovars were detected in studies performed in Bolivia and Brazil (Correa et al., 2004; Deem et al., 2012; Deem & Emmons, 2005; Orozco et al., 2013; Silva Pinto, 2010; Esteves et al, 2022), and the pathogen has been associated to nephritis in captive maned wolves (Diniz et al., 1999); however, the real role of carnivores in the leptospirosis cycle, the significance of the findings of positive antibodies to a few serovars and its impact on free‐living populations are still unknown (Deem & Emmons, 2005; Silva Pinto et al., 2010).…”
