Cross-sectional Survey on Antibiotic Prescription Practices Among Health Care Providers in Rombo District, Northern Tanzania

East African Health Res J.

East African Health Research Journal

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.

Impact of non-pyrethroid insecticide treated durable wall lining on age structure of malaria vectors in Muheza, Tanzania

BMC Res. Notes

BMC Research Notes

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.

Insecticide susceptibility status of human biting mosquitoes in Muheza, Tanzania

Tanzania Journal of Health Research, 19(3), pp.1–10.

Tanzania Journal of Health Research

Background: There has been a rapid emergence in insecticide resistance among mosquito population to commonly used public health insecticides. This situation presents a challenge to chemicals that are currently used to control mosquitoes in sub-Saharan African. Furthermore, there is limited information on insecticide susceptibility status of human-biting mosquitoes in some areas of Tanzania. This study aimed to determine insecticide susceptibility status of human biting mosquitoes in a rural area of north-eastern Tanzania. Methods: The study was conducted in two villages in Muheza district, Tanzania. Insecticide susceptibility bioassays were performed according to the World Health Organization standard operating procedures on two to five-day old human biting mosquitoes. The mosquitoes of each species were exposed to four classes of insecticides commonly used for malaria vector control. Mosquito mortality rates (%) were determined after 24 hours post insecticide exposure. Results: Mosquito species tested were Anopheles gambiae s.l., An. funestus, Aedes aegypti, and Culex quinquefasciatus species. Real-time PCR have showed that the main sibling species of An. gambiae complex and An. funestus group were An. gambiae s. s. (58.2%) and An. funestus s. s. (91.1%), respectively. All mosquitoes, except Ae. aegypti formosus were susceptible to pirimiphos-methyl (0.25%). An. gambiae s. l. was found to be resistant to permethrin (0.75%) but showed possibility of resistance to DDT (4%) and bendiocarb (0.1%). Our findings have shown that, An. funestus was fully susceptible to all insecticide tested. Conclusion: The present study has revealed different levels of insecticide susceptibility status to four classes of commonly used insecticides in the most common mosquito vectors of human diseases in north-eastern Tanzania. The findings of the present study call for integrated vector control interventions.

Seasonal Variation of Culex quinquefasciatus Densities Emerged from Pit-Latrines in Rural Settings, Muheza, Tanzania

SM J Public Health Epidemiol. 2017; 3(1): 1040.

SM Journal of Public Health and Epidemiology

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.

Community knowledge and attitudes on antibiotic use in Moshi Urban, Northern Tanzania: Findings from a cross sectional study

African Journal of Microbiology Research

There is increasing and spread of antibacterial resistance to antibiotics worldwide. The level of knowledge and attitudes of the community regarding the use of antibiotics in Tanzania is unknown. The present study identified determinants of knowledge and attitudes regarding antibiotics use in Moshi Urban district, Northern Tanzania. A cross-sectional study was conducted from April to June 2016 among community members whereby information was collected by using questionnaires on a sample of 292 randomly selected respondents. Descriptive statistics and logistic regression analysis were used in data analysis to assess factors associated with knowledge and attitude towards antibiotic use. Out of 292 respondents, 183 (62.7%) had good knowledge regarding antibiotics use while those with adequate attitude were 255 (87.3%). Respondents with no formal education, primary and secondary education had lower odds of having good knowledge regarding antibiotics use as compared to those with higher education degree (OR=0.04, 95%CI: 0.002-0.79), (OR=0.38, 95% CI: 0.14-0.97), and (OR=0.42, 95% CI: 0.16-1.06), respectively. Respondents with good knowledge regarding antibiotics use had higher odds of having adequate attitude towards antibiotic use (OR=3.16, 95% CI: 1.49-6.70). It was concluded that knowledge and attitude regarding antibiotic use is fair. Therefore, these findings are important in strategizing targeted antibiotic awareness campaigns among population.

Insecticide resistance testing in malaria vectors in Tanzania: Challenges in mosquito sampling and rearing under field conditions

Rwanda Journal Series F: Medicine and Health Sciences Vol. 2 No. 1, 2015

Rwanda Journal Series F: Medicine and Health Sciences

Background: The National Institute for Medical Research, Amani centre, in collaboration with National Malaria Control Programme, has been conducting annual insecticide resistance surveillance since 1999, aimed at early detection of resistance to insecticides used for malaria control in Tanzania. The Standard WHO method for larvae collection and rearing were used but challenges and limitations were encountered. For example rearing the larvae and adult mosquitoes using the Standard WHO method experienced 100% mortality for larvae; and adults in three days. The researchers therefore made modifications to the Standard WHO method to create suitable tools for the field environment. Methods: A ladle was created from an empty water bottle in which an oval hole longitudinally cut halfway from the bottom. Instead of using TetraMin as mosquito larval food, green algae were collected from mosquito breeding sites and used as larval food. Improvised heater of charcoal stoves and humidifier of wet fabric such as “Kanga” and “Kitenge” were also used. Results and conclusion: There was 90% larval survival, adult mosquito survived much better and the scientists had a total of 467 mosquitoes to run the insecticide susceptibility tests. Innovative ways are necessary under field conditions for mosquito breeding in susceptibility studies.
