The captures were undertaken by the teams from the Vigilância Ambiental and from the Laboratório de Biologia Parasitária of the Universidade Federal de Lavras (BIOPAR/UFLA), in October 2013. The entomological survey was performed during three consecutive nights for 12h per night (6:00pm to 6:00am). Eight HP light traps were installed being four in a small property equipped with a chicken

American visceral leishmaniasis (VL) is a vector-borne disease transmitted by some species of phlebotomine sandflies from the genus Lutzomyia. This neglected tropical zoonosis shows increasing urbanization process, since the end of the 1980s. After the emergence of foci of the disease in urban areas, VL has assumed an important role in public health. Although VL is widely prevalent in several parts of the world, diagnosing the illness is still difficult. We present a case of a 12-year-old girl with a history of recurrent fever, anorexia, cachexia, chronic fatigue, weight loss, left palpebral unilateral edema, persistent cough and pancytopenia. A diagnosis of VL was performed using a reference immunochromatographic rapid test. Identification of the infecting protozoan was directly obtained by PCR of bone marrow. The patient responded favorably to treatment using liposomal amphotericin B. This is the first report of human visceral leishmaniasis in the city of Lavras in the South of Minas Gerais State. This first report of VL highlighted the need of maintenance of permanent surveillance and control programs in the city of Lavras, including the active search of sandflies, human and canine cases. The current situation of Lavras should also be taken as an alert to other near cities where favorable eco-epidemiological conditions may exist.

Cutaneous Larva Migrans (CLM), also known as creeping eruption or ground itch, is a parasitic infection caused by larvae of the Ancylostoma braziliense and A. caninum species, which usually infect dogs and cats. CLM is considered a neglected disease that affects populations in developing countries located in tropical regions such as Brazil, India, and the Caribbean. Although the infection is more prevalent in areas with low economic and social development, sports activities on sand courts or beaches have led to infections among an economically privileged audience, including international travelers. Considering the current importance of CLM, this work describes an outbreak of the disease among residents of a high-end residential condominium located in the municipality of Lavras, Minas Gerais, Brazil. During the epidemiological investigation, five individuals with CLM were identified, and environmental risk factors for sand contamination were discovered. Preventive measures and controls for new cases were advised, as well as health education initiatives aimed at guiding the residents. The findings highlight the importance of CLM as a public health issue, even among populations with high socioeconomic status, and the need for increased awareness and control measures to prevent further outbreaks. This study adds to the growing body of evidence on the epidemiology of CLM and underscores the need for continued research to develop effective prevention and control strategies for neglected parasitic diseases.

A determinant factor in the pathology of canine angiostrongylosis seems to be related to the location of the parasite in the definitive host. Their presence inside the arteries and its branches, promoting mechanical and metabolic action on the wall of the vessels, may alter its homeostasis. Bronchoalveolar lavage (BAL) is a procedure that retrieves cells and other elements from de lungs for evaluation, and helps in the diagnosis of many pulmonary diseases. The aim of this study was to evaluate CD4+/CD8+ lymphocyte profile during the infection by Angiostrongylus vasorum, using cells retrieved using BAL. The identification of subpopulations of T lymphocytes by evaluating the co-expression of CD4 and CD8 receptor proteins has shown that despite the increase in both populations, there was a predominance of CD4+ T-cells, instead of CD8+ T-cells. These increases of CD4+ T-cells associated with the increase of the ratio between CD4+/CD8+ suggest polarization of a Th2 response. However, the immune cells, signaling factors, and cytokines that mediate such immunity and how and where they act within the body remain largely undefined during angiostrongylosis.

Visceral Leishmaniasis is a vector-borne disease that represents one of the most important public health problems in the world. This neglected tropical zoonosis shows an increasing urbanization process, since the end of the 1980s. The increase in ecotourism practices, mainly in regions nearby urban areas facilitates the interaction between companion animals, humans, and wildlife. Known as the land of the waterfalls, Carrancas is a 728 km² Brazilian municipality located at 1052m, in the southeast of Brazil. The region is surrounded by urban areas with autochthonous cases of Canine Visceral Leishmaniasis and lacking studies on the presence of vectors of Leishmania spp. The municipality is part of the most important ecotourism area, a renowned tourist destination in Brazil and abroad called Royal Road or “Estrada Real – ER. Due to the increasing number of travelers involved in ecotourism and exposing them to risk factors for diseases, we propose to investigate the presence of phlebotomine sandflies in a protected area in the southern state of Minas Gerais, which is constantly visited by tourists over the world. Six specimens of Lutzomyia longipalpis were captured in Carrancas. This is the first report of L. longipalpis in an ecotourism area south of Minas Gerais State. This record contributes to our knowledge of the geographical distribution of the main vector of American Visceral Leishmaniasis in Carrancas and alerts us to the need for permanent surveillance and health education at this location.
