SUMMARY The aim of this study was to identify blood meals of female sandflies captured in the municipality of Governador Valadares, an endemic area of visceral and cutaneous leishmaniasis, in the State of Minas Gerais, Brazil. From May 2011 to January 2012, captures were performed using HP light traps in four districts. There were 2,614 specimens (2,090 males and 524 females) captured; 97 engorged females were identified belonging to the species Lutzomyia longipalpis (82.1%) and Lutzomyia cortelezzii (17.9%). Considering simple and mixed feeding, the enzyme-linked immunosorbent assay revealed a predominance of chicken blood (43.6%) in Lutzomyia longipalpis, showing the important role that chickens exert around the residential areas of Governador Valadares. This finding increases the chances of sandflies contact with other vertebrates and consequently the risk of leishmaniasis transmission.

Abstract Background The two most abundant sand flies species in Honduran Pacific coast are Lutzomyia (Lutzomyia) longipalpis and Pintomyia (Pintomyia) evansi. Both species are proved vectors of the agent of for visceral leishmaniasis in South America. Although, visceral and cutaneous non-ulcerated leishmaniasis are endemic of the Central American Pacific, being the Non-ulcerative cutaneous leishmaniasis the most frequent manifestation. In this study, we evaluate the circulation of Leishmania spp in sand flies species in the El Tigre Island, an endemic area of Visceral and Non -ulcerative cutaneous leishmaniasis in Honduras. Results Six sand flies species were identified, being Lu. longipalpis (81%) and Pi. evansi (16%) the more abundant species. Leishmania (Leishmania) infantum DNA was found in 9 of the 96 specimens analyzed, 7 of these specimens was identify as Lutzomyia (Lutzomyia) longipalpis and 2 as Pintomyia (Pifanomyia) evansi, with an infection rate of 9.4% and 2.7% respectively. Conclusion Our results present the first record of Leishmania (L.) infantum DNA in Pintomyia (Pintomyia) evansi in a Non-ulcerative cutaneous leishmaniasis endemic region from Central America. Considering the natural infection of Lu. longipalpis our results suggest that Pintomyia (Pifanomyia) evansi might be a secondary vector of Leishmania (L.) infantum and probably involved in the disease’s transmission cycle. Undoubtedly, the detection of natural infections of in this region contributes to the understanding of the L. (L.) infantum infection epidemiology in Honduras

Abstract Phlebotomines of the genus Lutzomyia are important vector for species of Leishmania, the etiological agent of leishmaniasis. The aim of this study was to assess the diversity of sandflies in an endemic area for Visceral Leishmaniasis (VL). Sampling was performed in four localities on the coast of the municipality of Goiana, state of Pernambuco, Northeastern Brazil. Specimens were collected monthly on three consecutive nights, from November 2017 to October 2018. CDC light traps were installed at a height of 1.5 m above the ground, in two ecotypes (i.e. tree and animal facility), both in peridomestic areas. A total of 5,205 sandflies were collected, among which the species Lutzomyia longipalpis (99.85%; 5,197/5,205) was the most common, followed by Lutzomyia evandroi (0.13%; 07/5,205) and Lutzomyia whitmani (0.02%; 01/5,205). Specimens of L. longipalpis were collected throughout the study period and most of them were found near to the animal facilities. The findings from this research indicate that vectors for Leishmania infantum are present in the study area throughout the year, along with occurrences of vectors relating to Cutaneous Leishmaniasis (CL). Preventive vector control measures need to be implemented in Goiana to reduce the risk of infection for the human and animal populations.

All adults (n = 334) living in Brejo do Mutambal, an endemic area for cutaneous leishmaniasis, were included in this study. Contrary to our initial hypothesis, it was observed that men (23.7 ± 3.2 vs. 22.1 ± 2.6 kg/m²) and women (24.1 ± 4.7 vs. 22.5 ± 3.4 kg/m²) with cutaneous leishmaniasis presented higher body mass index than the controls.

We reviewed the records of 151 patients diagnosed with American cutaneous leishmaniasis (ACL) from 1993 to 2009 in the municipality of Japura, Paraná, Brazil. Gender, age, occupation, place of residence, location of lesions, type and number of lesions were analyzed. The prevalence rate of ACL was 11.5/10,000 hab, of which 84.7% were male, 58.3% lived in rural area and 49.0% were farmers. The most frequent age group was between 30 to 39 years (26.6%). Skin lesions occurred in 92.7% of the patients with predominance in the lower limbs (23.9%) and 49.1% of the records did not include the number of lesions location due to incomplete filling. A single ulceration was present in 44.4%. Japurá is an endemic area for ACL, requiring public actions and preventive education.

Lutzomyia Migonei

The main vector for visceral leishmaniasis (VL) in Brazil is Lutzomyia longipalpis. However, the absence of L. longipalpis in a region of autochthonous VL demonstrates the participation of other species in the transmission of the parasite. Studies conducted in La Banda, Argentina, and São Vicente Férrer, Pernambuco State, Brazil, have correlated the absence of L. longipalpisand the presence of L. migonei with autochthonous cases of VL. In São Vicente Férrer, Pernambuco, there was evidence for the natural infection of L. migonei with Leishmania infantum chagasi. Thus, the objective of this work was to assess the ecology of the sand flies L. longipalpis and L. migonei in Fortaleza, an endemic area for VL. Insect capture was conducted at 22 sampling points distributed across four regions of Fortaleza. In total, 32,403 sand flies were captured; of these, 18,166 (56%) were identified as L. longipalpis and 14,237 (44%) as L. migonei. There were significant density differences found between the vectors at each sampling site (indoors and outdoors) (p <0.0001). These findings confirm that L. migonei and L. longipalpis are distributed throughout Fortaleza, where they have adapted to an indoor environment, and suggest that L. migonei may share the role as a vector with L. longipalpis in the transmission of VL in Fortaleza.
