Grasslands are among the main important terrestrial ecosystems on the earth. Central Asia has the biggest grazing part in the world due to a favorable environmental condition for the development of livestock farming. Thus, the evaluation of the health and productivity of such an ecosystem is so pertinent. This study aims at analyzing the grassland capacity dynamics in Tajikistan (TJK) and Kyrgyzstan (KGZ) mountains using Geographic Information System (GIS) and Remote Sensing (RS) techniques. Initially, ...

Background . Malaria is one of the major public health problems in many tropical developing countries including Cameroon. Impregnated mosquito bed nets are one of the control measures put in place by the WHO and adopted by the Cameroon’s Ministry of Public Health to fight against malaria in pregnancy. This study was a population-based cross-sectional study that investigated the level of adherence, respondent’s knowledge, altitude, and practices toward malaria prevention and control. Methods . To investigate ...

Sulfate-reducing bacteria were enumerated in soils and water samples from Senegal ricefields using lactate and sulfate as substrates. When rice plants were severely injured by sulfides, maximum densities ranged from 107 to 109 bacteria g−1 of dry spermosphere or rhizosphere soil. Seven non-sporulating, mesophilic strains were isolated. The strains had motile curved cells and stained Gram-negative. Lactate, pyruvate, H2+ CO2, malate, fumarate, or ethanol could serve as electron donors. Organic acids ...

Abstract Understanding the influence of land use/land cover (LULC) on water quality is pertinent to sustainable water management. This study aimed at assessing the spatio-seasonal variation of water quality in relation to land use types in Lake Muhazi, Rwanda. The National Sanitation Foundation Water Quality Index (NSF-WQI) was used to evaluate the anthropogenically-induced water quality changes. In addition to Principal Components Analysis (PCA), a Cluster Analysis (CA) was applied on 12-clustered ...

There are about 13 parasitic infections that are responsible for significant morbidity and mortality but have not received the attention they deserve; thus, they are now known as "neglected tropical diseases" (NTDs). This study was aimed at evaluating the antihelminthic activities of Lophira lanceolata using an automated high-throughput method.The antihelminthic activity effect of the extracts against H. polygyrus was determined using an automated high-throughput method.

Large-scale implementation of Indoor Residual Spraying and Insecticide Treated Nets has been implemented in Plateau Department, Benin between 2011 and 2014. The purpose of this study was to monitor the frequency and mechanisms of pyrethroid resistance in malaria vectors following the implementation of vector control tools for malaria prevention. Anopheles larvae were collected in 13 villages twice a year from 2012 to 2014. WHO tube tests were used to assess the phenotypic resistance of each population ...
