Background A strategy to combat infectious diseases, including neglected tropical diseases (NTDs), will depend on the development of reliable epidemiological surveillance methods. To establish a simple and practical seroprevalence detection system, we developed microsphere-based multiplex immunoassay system evaluated utility using samples obtained in Kenya. Methods We immuno-assay simultaneously measure individual levels plasma antibody (IgG) against 8 antigens derived from 6 pathogens:...
In Japan, Japanese spotted fever, Lyme disease and severe fever with thrombocytopenia syndrome caused by Ixodidae species are endemic. To prevent control the diseases, fundamental understandings in tick ecology crucial. Hence, this study aimed to analyse richness abundance across Nagasaki prefecture including its remote islands from a wide range of environments. A total 74 sampling points screening during winter 2021–2022, using dragging method resulted 14,883 samples (279 adults, 7148...
Understanding the impacts of weather fluctuations, and environmental gradients, on abundance vectors is fundamental to grasp dynamic nature entomological risk for disease transmission. The mosquito Armigeres subalbatus (Coquillet) a common vector filariasis. Nevertheless, its population dynamics have been relatively poorly studied. Here, we present results from season long study where studied spatio-temporal patterns Ar. across altitudinal gradient Mt. Konpira in Nagasaki, Japan. Spatially,...
Okinawa is the largest, most urbanized, and densely populated island in Ryukyus Archipelago, where mosquito species diversity has been thoroughly studied. However, south-central fauna relatively poorly Here, we present results from a faunal survey urban environments of Nishihara city, Okinawa. Mosquitoes were sampled biweekly, April 2007 to March 2008, at 3 different environments: forest preserve, an animal farm, water reservoir. We employed 4 collection methods: 1) oviposition traps; 2)...
Abstract Larvae of the mosquito Uranotaenia novobscura ryukyuana Tanaka et al., have been reported in tree-holes, bamboo stumps, and artificial water containers. So far, no study has addressed role that density dependence weather fluctuations could played abundance this nonvector mosquito. A year-long was conducted on population dynamics using oviposition traps Okinawa, Japan. Time series analysis Ricker model were used to analyze association between growth relative humidity, temperature,...
Plasmodium knowlesi (Pk) is a malaria parasite that naturally infects macaque monkeys in Southeast Asia. Pk malaria, the zoonosis transmitted from infected to humans by Anopheles mosquito vectors, now serious health problem Malaysian Borneo. To create strategic plan control it important estimate occurrence of disease correctly. The rise has been explained as being due ecological changes, especially deforestation. In this research, we analysed time-series satellite images MODIS...
HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported African fishing villages, local distribution patterns of infection the communities surrounding these villages not thoroughly analyzed. The objective this study was to investigate geographical villages. In 2011, we applied age- and sex-stratified random sampling collect 1,957 blood samples from 42,617 individuals registered Health Demographic Surveillance System Mbita,...
Abstract The bamboo mosquito, Tripteroides bambusa (Yamada) (Diptera: Culicidae), is a mosquito species ubiquitous across forested landscapes in Japan. During 2014 we sampled adult mosquitoes from May to November using sweep net Nagasaki, We recorded and managed our field data Open Data Kit, which eased the overall process of management before performing their statistical analysis. Here, analyse resulting biweekly time series abundance time-series techniques. Specifically, test for density...
Abstract Mosquito surveillance is a fundamental component of planning and evaluating vector control programmes. However, logistical cost barriers can hinder the implementation surveillance, particularly in vector-borne disease-endemic areas outbreak scenarios remote where need often most urgent. The increasing availability reduced 3D printing technology offers an innovative approach to overcoming these challenges. In this study, we assessed field performance novel, lightweight 3D-printed...
Malaria remains a severe health problem in Sub-Saharan Africa, with approximately one million deaths and 365 cases each year. In terms of malaria control, insecticide-treated bednets are an effective tool, many organizations have distributed free or highly subsidized endemic areas. Nevertheless, some recipients do not use because social, environmental cultural factors. Making vulnerable populations aware the presence mosquitoes may improve bednet among people owning but using bednet. We...
Leukotriene (LT) D4 receptor in the granulation tissue formed air pouch-type allergic inflammation model rats was analyzed. Membrane preparation of obtained 3–9 days after antigen challenge has specific binding sites [3H]LTD4. Scatchard analysis showed that affinity (Kd) and density (Bmax) were not changed among 3-9 challenge. The Kd value (0.90 ± 0.12 nM) close to rat lung (1.00 0.24 guinea pig (0.86 nM). On other hand, Bmax (62 8 fmol/mg protein) higher than (21 4 but far less (405...
