Bovine trypanosomiasis is a significant health concern for livestock intensification in Côte d'Ivoire. This study aimed to determine the prevalence and distribution of pathogenic trypanosomes and identify the most infected cattle breed in northern Côte d'Ivoire. We examined 700 cattle and found that polymerase chain reaction (PCR) was more sensitive (12.3%) than microscopic observation (5.6%). Among the trypanosome species detected in naturally infected cattle, Trypanosoma vivax was 7.3%, Trypanosoma simiae tsavo was 6.7%, and Trypanosoma congolense was 0.4%. The overall prevalence of trypanosome infection in all cattle breeds was 12.3%, while the prevalence in individual breeds was 14.8%, 7.3%, 10.6%, and 12.3% for N'Dama, Baoule, Zebu, and Mere breed, respectively. The infected animals had low packed cell volume, influencing the prevalence. Our findings indicate that bovine trypanosomes are prevalent in Côte d'Ivoire, and their prevalence varies by region and breed. These pathogens include T. vivax, T. simiae tsavo, and T. congolense.

Vector control is an important component of the interventions aimed at mosquito‐borne disease control. Current and future mosquito control strategies are likely to rely largely on the understanding of the behavior of the vector, by exploiting mosquito biology and behavior, while using cost‐effective, carefully timed larvicidal and high‐impact, low‐volume adulticidal applications. Here we review the knowledge on the ecology of mosquito oviposition behavior with emphasis on the potential role of infochemicals in surveillance and control of mosquito‐borne diseases. A search of PubMed, Embase, Web of Science, Global Health Archive, and Google Scholar databases was conducted using the keywords mosquito, infochemical, pheromone, kairomone, allomone, synomone, apneumone, attractant, host‐seeking, and oviposition. Articles in English from 1974 to 2019 were reviewed to gain comprehensive understanding of current knowledge on infochemicals in mosquito resource‐searching behavior. Oviposition of many mosquito species is mediated by infochemicals that comprise pheromones, kairomones, synomones, allomones, and apneumones. The novel putative infochemicals that mediate oviposition in the mosquito subfamilies Anophelinae and Culicinae were identified. The role of infochemicals in surveillance and control of these and other mosquito tribes is discussed with respect to origin of the chemical cues and how these affect gravid mosquitoes. Oviposition attractants and deterrents can potentially be used for manipulation of mosquito behavior by making protected resources unsuitable for mosquitoes (push) while luring them towards attractive sources (pull). In this review, strategies of targeting breeding sites with environmentally friendly larvicides with the aim to develop appropriate trap‐and‐kill techniques are discussed. [ABSTRACT FROM AUTHOR]

Background: Malaria is a complex health problem related to socio-economic and environmental factors that cut across a number of sectors. Establishing intersectoral linkages is important to facilitate joint efforts to address the problem at all levels. The objectives of this study were to explore key sectoral engagements in malaria control policy formulation and implementation, and to determine decision and policy makers' opinions about different sectoral activities that contribute to malaria transmission and control in Tanzania. Methods: This study included documentary review, self-administered interviews and group discussion. Interviews and group discussions involved key informants at district and national levels. The sectors involved were health, agriculture, environment, livestock, fisheries, education, works, irrigation, water resources, land development, forestry, and community development. Results: Institutions and organizations that were involved in the development of the previous and current National Malaria Strategic Plan (2007-2013 and 2013-2020) were the Ministries of Health and Social Welfare, Prime Minister's Office of Regional Administration and Local Government, Public universities and non-governmental organizations. All the individuals involved in the development of the plans were either medical or health professionals. According to key informants, sectoral activities identified to contribute to malaria transmission included farming systems, deforestation, fishing, nomadic pastoralism, household water storage, water resource development projects, road and house construction and mining. The lack of intersectoral approaches in malaria control programme included the facts that the Health Sector does not involve other sectors during planning and development of policy guidelines, differences in sectoral mandates and management culture, lack of a national coordinating framework and lack of budget for intersectoral activities. Conclusion: The current strategies for malaria control in Tanzania need to address socio-economic and development activities across sectors and emphasise the need for intersectoral collaboration. It is recommended that the future of malaria control strategies should, therefore, be broad based and intersectoral in planning and implementation. [ABSTRACT FROM AUTHOR]
