“…(Nys. )albimanus had the highest biting activity between 17:00 and 19:00 hours, reaching a PHBC of 38.4 bites/night [52]. In general, our results indicated a lower PHBC rate compared to other reports conducted in other Neotropical countries.…”

BackgroundMore than 85% of the malaria cases in Panama occur in characteristically poor, rural and indigenous regions like Darien Province. Vector diversity, vector infection rate and spatial distribution are important entomological parameters of malaria transmission dynamics. Their understanding is crucial for the development of effective disease control strategies. The objective of this study was to determine the composition of Anopheles species, their natural infection rate and their geographic distribution to better understand the malaria transmission dynamics in Darién, Panama.MethodsAnopheline mosquitoes were captured during the rainy and dry season of 2016. We selected five communities where adult anophelines were collected using CDC light-traps, and through protective human-baited traps. Detection of natural infection and Plasmodium genotype in collected mosquitoes were detected via nested PCR through the amplification of Plasmodium 18s rRNA and the circumsporozoite protein gene, respectively.ResultsA total of 1,063 mosquitoes were collected, and nine Anopheline species were identified, with the predominant species being: An. (Nys.) darlingi (45.0%) and An. (Nys.) albimanus (42.6%). Among these mosquitoes, An. (Nys.) albimanus has historically presented an elevated frequency and abundance in all Panamanian regions. Natural infection with P. vivax was detected in a mosquito pool from the community Pueblo Tortuga (0.6%), three mosquito pools from Marraganti (1.7%), two pools from Bajo Chiquito (1.1%) and three pools from Alto Playona (1.7%). For An. (Nys.) darlingi mosquitoes, we detected seven positive pools from the community Bajo Chiquito (4.0%), two pools from Marraganti (1.1%) and two pools from Alto Playona (1.1%). This study was able to detect the P. vivax allelic variant VK210 in infected mosquitoes.ConclusionThe results from this study provide new information on the transmission dynamics associated with anopheline vectors in the Darién region. This is the first report of natural P. vivax infection in An. (Nys.) darlingi and its incrimination as a potential malaria vector in Panama. Additional studies are necessary to expand our knowledge and determine crucial parameters in malaria transmission in Darién, which in turn will aid the National Malaria Program in attaining an adequate malaria control strategy towards malaria elimination.

“…Of the references to physical health, 19% referred to infectious and parasitic diseases in the fishery. A large number of those focusing on infectious diseases related to HIV/AIDs (Entz, Prachuabmoh, Griensven, Soskolne, & Gan, ) and sexually transmitted diseases (STDs) more generally, while parasitic diseases commonly included malaria (Escovar, González, & Quiñones, ) and schistosomiasis (Chimbari, Dhlomo, Mwadiwa, & Mubila, ). General physical health (14%) brought together studies on generic chronic disease (Grimsmo‐Powney et al., ) and a small number of studies on very specific issues which were not categorized elsewhere (e.g., changes in chromosomal structure; Rodríguez‐Trigo et al., ).…”

Health in fishing communities: A global perspective

et al. 2018

In resource‐dependent communities such as fishing communities, human health underpins the ability of individuals and families to maintain viable livelihoods. Fishing is a dangerous occupation, in which fishers are exposed to health risks both on and offshore. Many of these risks and associated health concerns also extend to fishing families and wider communities. Despite the importance of health, there is a lack of understanding of the breadth of health issues affecting people associated with fishing. This study presents the findings of a scoping review of peer‐reviewed literature that identifies the range of health issues and health determinants studied in fishing communities around the world. The findings reveal a wide variety of documented health issues, but with greater emphasis on physical health and occupational and behavioral factors, with limited attention paid to mental health. The majority of studies focused on fishers themselves, as opposed to other subgroups within fishing communities. Geographic differences in the health topics investigated highlight prevalent concerns and offer potential to share insights and solutions across contexts. The breadth of findings illustrates the complexity of health for people dependent on fishing, and the relevance of the many health determinants in maintaining viable fishing communities. We propose that a social well‐being approach offers an integrative lens through which a better understanding of human health in fisheries can be achieved and used to inform fisheries management that is ecologically and socially sustainable.

“…albimanus was reported infected with P. falciparum [ 52 ] and with P. vivax VK210 [ 52 , 53 ]. Additionally, in this region another two Anopheles species have been reported infected with Plasmodium: Anopheles neivai infected with P. vivax VK210, P. vivax VK 247 and P. falciparum [ 52 , 53 ], and An. calderoni infected with P. vivax VK210 and P. falciparum [ 14 , 44 ].…”

BackgroundA proper identification of malaria vectors is essential for any attempt to control this disease. Between 40 and 47 Anopheles species have been recorded in Colombia, and eight species complexes have been identified in the last decade. An update of Anopheles species distribution and its relationship with malaria is required, particularly for newly identified members of species complexes.MethodsA cross-sectional entomological study was conducted at 70 localities in the highest malaria transmission areas in Colombia. In each locality, immature and adult mosquitoes were collected. All specimens were determined using morphological characters and confirmed used restriction profiles of Internal Transcribed Spacer 2 (PCR–RFLP-ITS2), and Cytochrome c Oxidase I (COI) sequence gene. To detect natural Plasmodium infections, enzyme-linked immunosorbent assay and nested PCR analysis were used. Distribution of Anopheles species was spatially associated with malaria incidence.ResultsA total of 1736 larvae and 12,052 adult mosquitoes were determined in the 70 localities. Thirteen Anopheles species were identified. COI sequence analysis suggested 4 new lineages for Colombia: for Anopheles albimanus (An. albimanus B), Anopheles pseudopunctipennis s.l., Anopheles neivai (An. neivai nr. neivai 4), and Anopheles apicimacula. Two members of species complexes were identified, as: Anopheles nuneztovari C, and Anopheles albitarsis I. Another seven species were confirmed. Four mosquitoes were infected with Plasmodium species, An. albimanus B and An. nuneztovari C. In Northwest of Colombia, An. nuneztovari C, An. albimanus, and Anopheles darlingi were present in the municipalities with highest annual parasitic index (API) (>35 cases/1000 inhabitants). In the north of South Pacific coast, with a similar API, An. nuneztovari C were widely distributed inland, and the main species in coastal regions were An. albimanus B and An. neivai s.l. In the South Pacific coast bordering with Ecuador, 3 Anopheles species were found in municipalities with high API (15–88 cases/1000 inhabitants): An. albimanus B, Anopheles calderoni and An. neivai s.l.ConclusionsIn the highest malaria areas of Colombia, 13 Anopheles species and four new lineages were found, which highlights the need for updating the species distribution. A DNA barcode analysis allowed the taxonomic identification to be refined, particularly for species complexes, and to improve the further understanding of their relation with malaria transmission.Electronic supplementary materialThe online version of this article (doi:10.1186/s12936-016-1421-4) contains supplementary material, which is available to authorized users.
