Recently, during 2021 - 2022, a new focus of tick nuisance and associated fever has been reported in some villages of Pathanamthitta district.Methods: The study on the diversity of tick fauna in Southern Kerala is limited. Therefore, a preliminary survey was carried out for the first time in this focus for implementation of future tick borne pathogen detection and control measures. This research may provide a proper understanding of tick density and acarological risk by tick ecology through surveillance and identification. A cross sectional study was conducted during the summer season of 2021 and 2022 in the tick bite infected area - Naduvathumoozhy, Vayakkara, Malayalappuzha and Pallikuzhi.Results: Ticks were manually collected from ruminants and by dragging method from vegetation. A total of 727 ticks of 8 different species were collected from the genus Amblyomma, Haemaphysalis, Hyalomma, and Rhipicephalus. The most prevalent species were H. bispinosa and H.turturis, at 38.7% and 29.1%, respectively. Ticks were sampled from 197 animals with the proportion of infestation being 73.60%. It was highest in goats (85.9%), followed by buffalo (73.6%) and cow (65.4%).Interpretation conclusion: The study concludes that, despite the absence of any TBD outbreaks, the Pathanamthitta district has a high diversity of tick fauna and a high rate of tick infestation in domestic ruminants, especially in goats. Hence active tick surveillance is necessary in order to prevent TBD outbreaks in future; the study also emphasizes the importance of performing tick surveillance in both KFD endemic and non-endemic regions.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139491612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anopheles gambiae, a prominent mosquito species, serves as a primary vector for transmitting malaria to humans. To address this issue, researchers have identified the D1-like dopamine receptor (DAR), specifically DOP2, as a promising target for developing new insecticides.Methods: The three-dimensional structure of DOP2 from A. gambiae was unavailable in the PDB database, an in-silico approach was used to model and validate the DOP2 protein's structure. The Discovery Studio 2021 program was then used to identify potential binding sites on the DOP2 protein. A virtual screening of 235 anti-parasitic compounds was performed against DOP2 using PyRx 0.8.Results: The screening demonstrated strong binding and interactions with active site residues of the DOP2 protein for five compounds: Diclazuril, Kaempferol, Deracoxib, Clindamycin, and Diaveridine. These compounds exhibited higher binding affinity values compared to the control (Asenapine). In addition, the predicted physiochemical properties for these compounds were within acceptable ranges, and there were no violations in druglikeness properties.Interpretation conclusion: These compounds show promise as potential new insecticides targeting the A. gambiae mosquito by inhibiting the DOP2 protein. However, additional experimental validation is required to optimize their efficacy as DOP2 protein inhibitors.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139491615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a study was conducted to identify the contribution of bamboo stumps to these disease vectors that were used in the flower garden as pillars to hold the bamboo flex fence.Methods: Two sizes of whole bamboo were used to hold fences around gardens at Dhaka University, Bangladesh, and they were painted red and green. Mosquito larvae and pupae were collected from bamboo stumps between July and August, and vectors were identified up to the species level. The data were analyzed using the STATA/MP 14.2 version.Results: We found 83.5% and 0.2% were Ae. albopictus and Ae. aegypti, respectively, and the rest were Culex and Armigeres species. Ae. albopictus, Ae. aegypti, and both species-positive bamboo stumps were 46.9, 0.7, and 47.1 percent, respectively. 54.5% of bamboo stumps had at least one mosquito species. The average stump depth for Aedes positive stumps (mean =11.7 cm, SE = 0.5) was significantly (p <0.001) higher than the Aedes negative stumps (mean = 9.5 cm, SE = 0.4). 53.8% and 38.0% stumps were found Aedes positive on the ground and upper sides of fences, respectively, and found significant (p<0.01) differences between both sides. A zero-inflated negative binomial count model is significant at a 5% level of significance, χ2(4) = 11.8, p = 0.019 (<0.05) for Ae. albopictus.

This pressing issue gains prominence in light of a recent study conducted by Ronald et al. in Uganda, which illuminates the factors contributing to the elevated prevalence of malaria in economically disadvantaged areas. The study underscores the efficacy of interventions such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS) in curtailing malaria incidence. Additionally, the World Health Organization's endorsement of the RTS, S/AS01 (RTS, S) malaria vaccine presents a promising development in the battle against this devastating disease. This letter underscores the imperative nature of implementing comprehensive strategies in India, which encompass widespread ITN distribution, the expansion of IRS programs, and the integration of the RTS, S/AS01 vaccine into the national immunization regimen. These concerted efforts are pivotal in furnishing cost-effective preventive measures to counter the mounting wave of malaria cases in India. Confronting malaria through a multifaceted approach stands as an essential approach to mitigate the disease's burden and ultimately safeguard the lives of India's vulnerable populations.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139491620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, an investigation was carried out to find out both epidemiological and entomological reasons behind the outbreak.Methods: An Entomological survey was carried out in 24 wards of Port Blair Municipal Council (PBMC) area, epidemiological data of last six years (January to December of 2017-2021 & January to October of 2022) and patient details of the year 2022 were collected. Both the epidemiological and entomological data were analyzed concerning time and place.Results: During this outbreak period tyres (22.4%) came out as a major breeding habitat followed by small discarded materials (17.5%), metal drums (15.3%), and plastic drums (11.7%). In rainy season peri-domestic breeding (55%) was more than the domestic breeding (45%) habitat. Ae. aegypti had a high preference for indoor large containers (100-1000 L) like plastic tank, metal drum and cement tank whereas Ae. albopictus prefers to breed in medium sized plastic container (20-100 L) and outdoor water receptacles like tyres, flower pots, domestic discarded materials etc.Interpretation conclusion: By source reduction, indoor space spray and outdoor fogging vector density was controlled which curtailed the transmission and within 8 weeks decreasing trend of dengue cases were noticed. A regular entomological survey is very important to know the seasonality and key breeding habitats of the vector for proper planning of vector control.","PeriodicalId":17660,"journal":{"name":"Journal of Vector Borne Diseases","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139491569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
