I am a Senior Research Scientist in Medical Entomology working with the National Institute for Medical Research (NIMR), Department of Innovations, Commercialization and Technology Transfer Headquarters, Dar es Salaam, Tanzania. I hold a PhD in Medical Entomology, a Master of Science (MSc) in Applied Zoology and Bachelor of Science (BSc) (Hons) in Zoology, Wildlife Science and Conservation. I have participated in a number of researches in areas of mosquito ecology, mosquito insecticide resistance, malaria entomological and parasitological surveys, and ethical issues in health research and innovation researches in food security. I have also participated in a multi-country study on the District Comprehensive Assessment; Global Fund Health Impact Evaluation on HIV/AIDS, Tuberculosis and Malaria. I am a member of Pan-African Mosquito Control Association (PAMCA), Tanzania Public Health Association (TPHA) and Wildlife Conservation Society of Tanzania (WCST). In my academic and research carriers, I have received a number of awards which include the “Ngorongoro Conservation Prize” for being the best student in Wildlife Field Course, the “First Young Women Scientist Award” and the “Mount Kilimanjaro Scientific Award”. I have published 11 scientific papers in peer-reviewed journals. My research interest is on human biting mosquito vectors. Mosquito-borne diseases are major obstacle to growth of many countries. I am interested on understanding the behavior patterns and insecticide resistance in of mosquito vectors of human diseases, how these affect diseases transmission and how research findings can be used to have timely and effective control strategies.

Background: Irrational and inappropriate antibiotic prescription is a worldwide phenomenon – increasing the threat of serious antibiotic resistance. A better understanding of health care providers’ knowledge, attitudes, and prescription practices related to antibiotics is essential for formulating effective antibiotics stewardship programmes. The aim of the present study was to assess knowledge, attitudes, and prescription practices toward antibiotics among health care providers. Methods: A descriptive cross-sectional study was conducted between March and June 2017 to assess knowledge, attitudes, and prescription practices toward antibiotics among health care providers in the Rombo district of northern Tanzania. A total of 217 health care providers were interviewed using a structured questionnaire. Results: Over half of health care providers (n=111, 51.2%) strongly agreed that the inappropriate prescription of antibiotics puts patients at risk. More than half (n=112, 51.6%) reported that their decision to start antibiotic therapy was influenced by a patient’s clinical condition, while 110 (50.7%) reported they were influenced by positive microbiological results in symptomatic patients. Almost two-thirds of the health care providers (n=136, 62.7%) reported that they had access to and used antibiotic therapy guidelines. Less than a quarter (n=52, 24.0%) received regular training and education in antibiotic prescription practice in their work place. Conclusion: Knowledge and prescription practice of antibiotics among health care providers was generally unsatisfactory. Training and education for health care providers is needed in the area of prescribing antibiotics.

Objective Malaria vectors control interventions are designed to cause immediate killing or shorten mosquito lives, therefore does not allow enough time for the development of the parasites to infective stage. The wall lining is new malaria vectors control intervention in Tanzania where its impact on age structure is not well known. Therefore this study aimed at determining the impact of non-pyrethroid durable wall lining on the age structure of malaria vectors. Results Higher proportions of An. gambiae sensu lato (57.1%, z = 2.66, P = 0.0077) and An. funestus (64.8%, z = 3.38, P = 0.001) were collected in the control clusters. Unexpectedly, significantly higher proportion of parous An. gambiae s. l. were collected in the intervention clusters (z = − 2.78, P = 0.0054). The wall lining intervention has demonstrated low impact on age structure of An. gambiae s. l., this call for further studies on the efficacy of the intervention.

Background: Culex quinquefasciatus is a vector of lymphatic filariasis and a biting nuisance in many developing countries with a warm and humid climate. In north eastern part of Tanzania, the burden of chronic lymphatic filariasis disease is still high. There is limited information on the factors that contribute to higher abundance of this mosquito species in rural areas. This study was therefore aimed at assessing the seasonal variation of Cx. quinquefasciatus abundance in pit latrines in rural areas in Muheza. Methods: A cross-sectional study was conducted in rural settings of Muheza district for the duration of 11 months consecutively in 24 villages which were randomly selected. Collection of adult Culex mosquitoes emerged from wet pit latrines was done by using emergence traps. In each village three houses were selected basing on the presence of pit latrines. Results: A total of 12,762 mosquitoes consisting of Culex quinquefasciatus (12%) and Culex cinereus (88%) species were collected from 24 villages. Majority of Cx. quinquefasciatus mosquitoes were collected during cool and dry season followed by long rains season with 48.52% (n=722) and 41.53% (n=618), respectively. Only one Cx. quinquefasciatus (0.07%) was collected during hot and dry season. Conclusion: The present study has revealed the variation in the densities of Cx. quinquefasciatus emerged from pit latrines across the seasons. Wet pit latrines were found to be potential breeding sites for Cx. quinquefasciatus. The present study has provided important information on mosquito seasonality density in rural setting for employing alternative vector control such as larviciding in wet pit latrines.
