“…Echazú et al (2015) described inadequate sanitation and unsafe water supply as risk factors for parasitic human infection. In Brazil, this species is a natural host of Schistosoma mansoni, which causes schisostomiasis and affects approximately 6 million people (Martins et al 2015). Paraense (2005) recorded this species in Jujuy province and gave the city of San Salvador de Jujuy as a generalized locality without specifying an exact collection site.…”

The family Planorbidae comprises freshwater gastropods with planispiral, spiral and limpet-shaped shells. Subfamily Planorbinae sensu stricto, has a richness of almost 300 species, with some of the main genera being Biomphalaria Preston, 1910 and Drepanotrema Fischer & Crosse, 1880. Some Biomphalaria species are of concern to human health as they are intermediate hosts of blood flukes in Latin America. In Argentina, the family Planorbidae is represented by 15 species in four genera. In Northern Argentina (NOA region), records of the family are scarce, and most of them are a result of occasional collecting. We provide an updated checklist of Planorbinae in NOA resulting from fieldwork, material in malacological collections, and data in the literature. Nine species occur in the area: four species of Biomphalaria and five of Drepanotrema. Among Biomphalaria species, we recorded Biomphalaria straminea (Dunker, 1848), which is considered a natural host of the blood fluke Schistostoma mansoni Sambon, 1907, for first time in Salta province; the known geographic distribution of B. straminea is extended in the country.

“…The WHO list was chosen as a reference to this study because it is applicable worldwide and widely considered as the main reference about NTD. The identified diseases, classified as being possibly prevalent, were: Buruli ulcer [1,8], schistosomiasis [1,[9][10][11][12], trachoma [1,10,12,13], echinococcosis [1,10,14,15], rabies [1,10,16,17], and foodborne trematodiases [1,18]; and those classified as prevalent were: leprosy [1,10,12,15,16,19], Chagas' disease [1,9,10,15,16], leishmaniasis [1,10,15,16,19], taeniasis and cysticercosis [1,12,20,21], soil-transmitted helminthiases [1,9,12,21,22], and dengue [1,…”

Introduction: Implementation of prevention and control measures for communicable diseases in border regions can be challenging and lead to inefficient attempts to control them. We describe evidences on the strengths, weaknesses, opportunities and challenges regarding implementation of health interventions for control, prevention and treatment of selected neglected tropical diseases (NTD), a group of transmissible diseases typically prevalent in tropical countries and vulnerable populations, in the tri-border between Brazil, Argentina, and Paraguay. Methodology: A systematic literature review of observational and experimental studies was conducted, using PubMed and Bireme databases. Eligibility criteria were location (tri-border area) and subject (health interventions). Results: Of a total of 595 references identified, 34 studies were included (18 pertaining to leishmaniasis, 11 to dengue, 2 to leprosy, 2 to soil-transmitted helminthiases and 1 to Chagas’ disease), with an inclusion rate of 6.4%. The main strengths were the similarity of health interventions between countries and easiness of mobility and communication flows. The main weaknesses were access to rural areas and discrepancies in the number of studies between countries. As for opportunities, we identified increased tourism, economic development and recent increasing research in this field. The main challenges were the absence of studies regarding other prevalent NTD in the region and movement of goods, animals and people across borders. Conclusions: Although epidemiological studies are still needed to better understand and assess the prevalence of NTD in the area, mainly in Paraguay, these findings can inform decision-makers and health managers to plan a common strategy to address NTD.

“…É uma doença prevalente em áreas tropicais e subtropicais no qual, segundo o Ministério da Saúde (2014), dentre os países das Américas, o Brasil possui a maior área endêmica para a doença. No ano de 2017, 3.836 casos foram notificados e confirmados em todo o território brasileiro, fato esse que corrobora que a doença é um grave problema de saúde pública no país (BRASIL, 2018;MARTINS et al, 2015).…”

A esquistossomose é uma doença parasitária crônica causada pelo platelminto Schistosoma mansoni da classe trematoda. Sua disseminação ocorre por um ciclo heteroxeno: com presença de hospedeiro intermediário que é o molusco do gênero Biomphalaria, popularmente conhecido como caramujo e por um hospedeiro definitivo que é o homem. Segundo a Organização Mundial de Saúde, 6 milhões de indivíduos são portadores da forma intestinal da doença no Nordeste; principalmente em Alagoas, um estado endêmico, banhado por rios, lagos, açudes e com sistema de saneamento básico deficiente, o que justifica a alta incidência, prevalência e sua classificação em área de risco. Os índices epidemiológicos que foram avaliados em 70 dos 102 municípios trazem valores de 12.652 casos em 2013 com, 49 mortes notificadas no mesmo ano. Outros índices apresentados mostram que, em 2014, Alagoas ainda era a região do Nordeste e do Brasil com mais notificações de casos de esquistossomose. O estudo objetiva analisar a atuação do sistema imune humano durante a fase aguda de infecção por esquistossomose e compreender o processo da eosinofilia causada pela presença do Schistosoma mansoni no organismo infectado. Então, compreender o curso e fisiologia da infecção, assim como o mecanismo de resposta do sistema imune no combate a parasitemia é fundamental frente aos dados alarmantes de casos, a fim de auxiliar em novas descobertas contra a infecção, melhorar as formas de tratamento e qualidade de vida do portador.
