“…Reithinger and Davies (1999) suggested that more infected animals are found in rural habitats because of the proximity of non-domestic animals and dogs to disease vectors, given that transmission typically occurs in the wild. However, in a study of 429 dogs in endemic CL regions of Minas Gerais, Maywald et al (1993) reported that only 1% tested positive in rural areas, whereas 10.6% were found to be infected in urban environments. According to Falqueto et al (1986), the CL transmission cycle possesses unique features in each endemic region, and data cannot always be extrapolated from one area to another.…”

ABSTRACT. Leishmaniasis is a disease caused by protozoa of the genus Leishmania. Two distinct forms are recognized: visceral leishmaniasis (VL) and cutaneous leishmaniasis (CL). In the Americas, the causative agent of VL is L. infantum chagasi, whereas L. braziliensis is principally responsible for CL. Domestic dogs constitute the main source of VL in urban environments, and have also been implicated in CL epidemiology. We carried out molecular and serological surveys to detect Leishmania infection in dogs from the municipality of Ituberá in Bahia, Brazil. Furthermore, we identified risk factors associated with illness in dogs from this locality. Blood samples were collected from 399 dogs and tested using an indirect immunofluorescence assay (IFA) and polymerase chain reaction (PCR) to detect Leishmania spp antibodies and L. infantum chagasi and L. braziliensis DNA, respectively. Dogs were clinically evaluated and tissue samples from those exhibiting skin lesions were examined for parasites. In addition, the dog owners completed an epidemiological questionnaire to identify factors associated with infection. Skin lesions consistent with CL were found on 37 (9.3%) of the evaluated animals, but parasitological examination was negative for all samples. The IFA returned positive results for 60 (15%) dogs. PCR identified DNA from L. braziliensis in 86 (21.6%) animals, where as all samples proved negative for L. infantum chagasi. The 134 dogs (33.6%) testing positive using IFA and/ or PCR were considered infected, and of these, only 13 demonstrated skin lesions. Animals from rural areas were 3.39-times more likely to be infected compared to those in urban environments.

“…A soropositividade canina para leishmaniose tegumentar nas áreas estudadas indica que a transmissão é ativa. Maywald et al (1993), estudando regiões endêmicas de LTA em Minas Gerais, comparou os achados caninos de uma área rural estudada e de uma área urbana e constatou que, de 429 cães, apenas 1% mostrou-se reagente na RIFI na área rural, enquanto 10,6% foram reagentes na mesma técnica na área urbana. O número de casos de LTA humana, fornecidos pela Fundação Nacional de Saúde entre 1994 e 1996, foi de 51, estando assim distribuídos nas quatro áreas trabalhadas: nove casos em Taquari, 25 em Praia Grande, sete em Graúna e dez em Várzea do Machado.…”

“…Due to this microepidemia, the infection of dogs in rural and urban areas in the municipalities of Uberlândia and Coromandel was investigated and an active canine infection was observed in the region. Thus, it was considered that dogs, as important reservoirs of the disease, could form new endemic outbreaks in urban areas (MAYWALD et al, 1993;1996). (MAYWALD et al, 1993;1996).…”

Leishmaniasis is a disease that can affect visceral organs (visceral leishmaniasis; VL) or mucous membranes and skin, causing lesions of different forms and levels of severities (tegumentary leishmaniasis; TL). Like several others, leishmaniasis is a neglected disease, as the pharmaceutical industry seems to show little to no interest in developing new drugs targeting the disease. This study aims to trace the epidemiological profile of leishmaniasis in the Municipality of Patrocínio, State of Minas Gerais, over a period of time. Secondary data of reported cases from 2000 to 2017 were analyzed as provided by the Patrocinio Health Department. As no literature was found on the status of such a disease in Patrocinio, it is important to trace the epidemiological profile of leishmaniasis in the area. The findings pointed out that the disease affected predominantly male in the economically active population, mainly from the urban area, and that it had no relationship with professional activity. Twenty-two cases of leishmaniasis (15 of TL and 7 of VL) were reported, all of which were treated and cured. Five cases of TL and 1 case of VL were autochthonous, and confirmed cases of canine infection took place in 2011, 2016 and 2017.
