“…Cattle act as maintenance hosts for the Hardjo serovar (Ellis et al, 1981), while the Canicola serovar is associated with domestic dogs (Schuller et al, 2015), acting as sources of infection in farms (Barcellos et al, 2003). The Butembo serovar has been described in cattle and fallow deer ( Ozotocerus bezoarticus ) in Santa Catarina and Mato Grosso do Sul States, respectively (Saldanha et al, 2007; Vieira et al, 2011), in addition to being potential sources of infection for NHPs. What is more, numerous serogroups/sorovars traditionally recognized in domestic hosts have been isolated from wild hosts, including canids, cetaceans, cingulata, afrosoricidal, chiropterans, primates, in addition to reptiles and amphibians (Bertelloni et al, 2019; Cilia et al, 2021; Silva, Loffler, Brihuega, et al, 2016, Silva, Loffler, Santos, et al, 2016).…”

The environments in which neotropical primates live have been undergoing an intense fragmentation process, constituting a major threat to the species' survival and causing resource scarcity, social isolation, and difficulty in dispersal, leaving populations increasingly vulnerable. Moreover, the proximity of wild environments to anthropized landscapes can change the dynamics of pathogens and the parasitehost-environment relationship, creating conditions that favor exposure to different pathogens. To investigate the previous exposure of free-living primates in Rio Grande do Sul State (RS), southern Brazil, to the bacterial agents Leptospira spp. and Brucella abortus, we investigated agglutinating antibodies against 23 serovars of Leptospira spp. using the microscopic agglutination test and B. abortus acidified antigen test in primate serum samples; 101 samples from primates captured between 2002 and 2016 in different forest fragments were used: 63 Alouatta caraya, 36 Alouatta guariba clamitans, and 02 Sapajus nigritus cucullatus. In addition, the forest remnants where the primates were sampled were characterized in a multiscale approach in radii ranging from 200 to 1400 m to investigate the potential

“…Streptomycin was one of the first antibiotics to be used for leptospirosis therapy and is considered today one of the best treatment options since it easily penetrates the kidneys and destroys the leptospires in renal tubules (60,61). In bovines, a study conducted by Saldanha et al (62) found that the effectiveness of streptomycin sulfate in controlling leptospirosis restored reproductive function in 92% of animals.…”

Leptospirosis is a zoonosis distributed worldwide, endemic mainly in humid subtropical and tropical countries, with epidemic potential. It affects a range of both wild and domestic animals, including sheep, which transport leptospires in their urine and, therefore, can infect other animals and humans who deal with them. Therefore, leptospirosis is characterized as an occupational zoonosis. In individual herds leptospirosis can cause severe economic loss due to miscarriages and outbreaks of mastitis with a significant reduction of milk production. The disease is caused by Leptospira interrogans, which was reclassified into 13 pathogenic species, and distributed into more than 260 serovars classified into 23 serogroups. The clinical signs of infection may vary depending on the serovar and host. In maintenance hosts, antibody production is generally low; there are relatively mild signs of the disease, and a prolonged carrier state with organisms in the kidneys. In incidental hosts, the disease may be more severe, with high titers of circulating antibodies and a very short or nonexistent renal carrier state. In general, young animals with renal and hepatic failure have more serious infections than adults. Several diseases may produce symptoms similar to those of leptospirosis, so that laboratory confirmation, through microscopic agglutination test, for example, is required. The effectiveness of treatment depends on early diagnosis and appropriate therapy, depending on clinical features, since leptospirosis can develop into chronic liver disease and nephropathy, progressing towards death. Improvements in habitation and sanitary conditions, rodent control, vaccination, isolation and treatment of affected animals are the main measures for the control of leptospirosis.

“…Foi observada a eficácia do sulfato de estreptomicina no controle de leptospirose, com retorno à vida reprodutiva normal de 92% dos animais (SALDANHA et al, 2007). No Reino Unido, a vacinação anual por um período de cinco anos, associada ao tratamento dos animais infectados com diidroestreptomicina, foi suficiente para controlar e erradicar a doença (LITTLE et al, 1992).…”
