Validity and reliability of enzyme immunoassays using Leishmania major or L. infantum antigens for the diagnosis of canine visceral leishmaniasis in Brazil.

Background: American visceral leishmaniasis is caused by the protozoan Leishmania infantum. Dogs are the main reservoirs in the domestic transmission cycle. The limited accuracy of diagnostic tests for canine leishmaniasis may contribute to the lack of impact of control measures recommended by the Brazilian Ministry of Health.

Profile and geographic distribution of reported cases of visceral leishmaniasis in Campo Grande, State of Mato Grosso do Sul, Brazil, from 2002 to 2009.

Introduction: This study sought to describe the profile and geographic distribution of reported cases of visceral leishmaniasis (VL) in the City of Campo Grande, State of Mato Grosso do Sul (MS), Brazil, from 2002 to 2009.

Methods: Human data were collected from the Brazilian National Information System for Notifiable Diseases. Canine cases and entomological data were obtained from the Information Service for Canine Visceral Leishmaniasis Control/Campo Grande, MS.

An assessment of the genetic diversity of Leishmania infantum isolates from infected dogs in Brazil.

Correlations between the genetic diversity of Leishmania infantum (syn. L. chagasi) isolates and their respective geographic origins support the theoretic assumption that visceral leishmaniasis probably originated in the Old World.

Detection of Leishmania DNA in phlebotomines captured in Campo Grande, Mato Grosso do Sul, Brazil.

Over the past years, leishmaniases have become a public health issue in the Brazilian state of Mato Grosso do Sul, particularly in Campo Grande, the state capital. The purpose of this study was to detect the presence of Leishmania DNA in the population of phlebotomine sandflies using DNA amplification by PCR. Insect captures were carried out from 4 pm.

An epidemiological description of human-hazardous incidents caused by nonhematophagous bats in Brazil, 2002-2003.

The interaction of bats with humans and pets increases the risk for rabies transmission. The purpose of the present study was to describe and analyze the epidemiological picture of injuries and related incidents caused by bats, to characterize the profile of these incidents, and to define recommendations for improving the health care delivered to patients. Fifty-three records of human anti-rabies treatment of injuries or related incidents caused by bats in Campo Grande, MS, Brazil, in 2002 and 2003 were investigated.
