Leishmania chagasi in Opossums (Didelphis albiventris) in an Urban Area Endemic for Visceral Leishmaniasis, Campo Grande, Mato Grosso do Sul, Brazil

The main purpose of this study was to investigate natural infection by Leishmania in phlebotomine females in a visceral-leishmaniasis focus in Antonio João county in Mato Grosso do Sul State, Brazil. Between June and October 2003, the digestive tracts of 81 females captured in Aldeia Campestre, Aldeia Marangatu and Povoado Campestre were dissected. The females were separated by species, location, area and date of capture into 13 groups and kept in ethanol 70%. To identify the Leishmania species using the PCR technique, amplifications of the ribosomal-DNA (rDNA) and mini-exon genes were analyzed. Of the 81 specimens, 77 (95%) were Lutzomyia longipalpis, making this the most common species; only one specimen of each of the species Brumptomyia avellari, Evandromyia cortelezzii, Evandromyia lenti and Nyssomyia whitmani was found. Trypanosomatids were identified in eight of the nine groups of Lutzomyia longipalpis (10.39%) one group from Aldeia Campestre, one from Aldeia Marangatu and six from Povoado Campestre; of the eight groups, one from Aldeia Marangatu and another, with promastigotes forms also confirmed by dissection (1.23%) from Povoado Campestre, were identified by PCR as Leishmania chagasi (2.6%). The other groups gave negative results. These findings indicate that there is a high risk of leishmaniasis transmission in this area.

Forty-one naturally infected dogs with visceral leishmaniasis from an urban area of Corumbá (Mato Grosso do Sul-BRAZIL) were studied and three types of lung involvement due to visceral leishmaniasis were characterized; a cellular, a cellular-fibrotic and a fibrotic type. These types seem to represent a sequential evolutive proce'as. Visceral leishmaniasis frequently causes an interstitial pneu monitis in naturally infected dogs (80.5%) as well as in man and experimentally infected hamsters.

The Brazilian city of Três Lagoas, Mato Grosso do Sul State, has experienced an urban outbreak of visceral leishmaniasis since 2000. In 2002, due to the increase in the number of cases, 46 families with cases of visceral leishmaniasis were studied to verify the prevalence of asymptomatic infection in household contacts. Indirect immunofluorescence and ELISA showed a 36.4% positive infection rate. There were no cases of symptomatic disease among these contacts. There was no statistically significant difference in gender or age. Median age was 21 years, and the 10-19-year age bracket was the most heavily affected (23%). As for family characteristics, no differences were observed in schooling or family income; most families (58.7%) owned their homes, which were built of masonry (97.8%) and had adequate infrastructure. All the families reported what were probably phlebotomine sand flies in the peridomicile. In conclusion, asymptomatic visceral leishmaniasis infection is frequent and occurs in both males and females, regardless of age.

Objectives: To verify the number of visceral leishmaniasis (VL) cases in Brazil and its states and twin cities, with a focus on the state and twin city with the highest number of cases. We investigated social, demographic, laboratory and clinical aspects of these cases. Methodological design: We performed a descriptive study using a quantitative approach and data from 2010 to 2019 that were obtained through a public domain website, the Informatics Department of the Unified Health System. The incidence rate of VL cases was calculated per 100,000 inhabitants. software. Results: In Brazil, 35,886 VL cases were reported, with 2,834 cases in international border states and 148 cases in twin cities. The state and twin city with the highest number of cases were Mato Grosso do Sul (1,834 cases) and Corumbá (94 cases), respectively, with annual mean incidence rates of 6.4 and 8.3 cases per 100,000 inhabitants. In Mato Grosso do Sul and Corumbá, the disease was more frequent in male and brown-skinned individuals who had up to 8 years of education (age range: 1 to > 80 years old). Most of the cases occurred in urban areas, was diagnosed by laboratory tests and evolved to cure (p < 0.05). Conclusions: A high number of VL cases in Brazil was found during the period of study. The cases were distributed in 10 states with international borders and eight twin cities. These findings draw attention to the greater need for management programs to control and prevent VL.
