High prevalence of Rickettsia felis in patients with fever of unknown origin was revealed in the north-central Bangladesh from 2012 to 2013. Subsequently, in this study, prevalence of R. felis in cats and cat fleas (Ctenocephalides felis), together with febrile patients, was studied by PCR detection of 17 kDa antigen gene and DNA sequencing. R. felis was detected in 28% (28/100) and 21% (14/68) of cat blood and cat flea samples, respectively, whereas 42% (21/50) of patients were positive for R. felis. R. felis-positive cat fleas were detected at significantly higher rate on R. felis-positive cats. The results suggested a potential role of cats and cat fleas for transmission of R. felis to humans in Bangladesh.
From July 2015 to December 2016, the presence of rickettsial pathogens was investigated for 414 patients with unknown fever in eight places in all the divisions of Bangladesh. Rickettsia felis was identified in blood samples from all the regions (overall detection rate, 19.6%), suggesting nationwide prevalence of R. felis infections.
Background: The misuse and overuse of antibiotics can lead to antibiotic resistance. Thus, it is important to have adequate knowledge and attitude toward antibiotic use and resistance for all specially the medical students who are the future healthcare practitioners. The aim of this study was to assess the knowledge and attitude toward antibiotic use and resistance among 4th year students of Shaheed Monsur Ali medical college. Material Methods: This cross-sectional study was conducted in Shaheed Monsur Ali medical college, Dhaka, Bangladesh from October 2022 to December 2022. A structured questionnaire was administered to 126 randomly selected undergraduate medical students. Results: In our study, the percentage of male and female was same. Majority of the participants (55.56%) always get a prescription before starting antibiotics. Most of the participants (60.32%) never stop taking the prescribed antibiotics after their symptoms improved. Majority of the participants (54.76%) sometimes completed the course of the prescribed antibiotic treatment. In our study, majority of the participants (54.76%) sometimes take the correct dose of their antibiotics at the right time for the full duration. In this study, majority of the participants (47.62%) never save the remaining antibiotics for next time they get sick. Majority of the participants (73.02%) sometimes give leftover medication to friends or family if they get sick. For cough or sore throat, majority of the participants (48.41%) sometimes prefer taking an antibiotic. Most of the participants (69.05%) never buy the same antibiotics if they are sick that helped them get better when they had the same symptoms before. Most of the participants (96.03%) always check the expiry date of the antibiotic before using it. Knowledge level of antibiotic in majority of the participants (47.62%) was very good. Knowledge level of antibiotic resistance in majority of the participants (54.76%) was very good. Attitude level of antibiotic usage in majority of the participants (34.13%) was average, followed by 32.54% had bad, 32.54% good attitude level. Conclusion: From the findings of the study, it can be concluded though the knowledge level of the medical students is adequate, they are not careful about the usage of antibiotics and often misuse it. The students tend to not follow the rules of the usage guideline of antibiotics which ultimately results in antibiotic resistance. They should be more conscious to follow the guidelines of antibiotic usage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
