Giardiasis in dogs and cats in the Belgrade area

Giardia infection is an ongoing problem in Serbia, since 8.0% of the children in the Belgrade area are infected. In the light of the zoonotic potential of Giardia infection, a total of 248 companion animals (167 dogs and 81 cats) were examined for giardiasis in the same urban area. The overall rates of infection in dogs and cats were 14.4% (24/167) and 22.2 % (18/81), respectively. Significantly (p lt 0.05, p lt 0.01) higher infection rates were found in stray (18.7%) and farm (36.4%.) dogs than in household pets (7.4%.). Furthermore, the rate of infection was significantly (p lt 0.01) higher in domestic cats than in household dogs (22.2% vs. 7.4%). The owners and all 16 of their family members of five out of the six household pet dogs excreting Giardia were Giardia-negative, while both the owner of one dog and the only other family member were Giardia-positive. The data demonstrate that potential animal reservoirs (dogs and cats) exist in urban Serbia and underline the possibility of transmission between dog and man in close contact, thus having important implications for the epidemiology of giardiasis in urban areas

Comprehensive qualitative evaluation of the first ever full-time online course for medical students in one middle-income country

ABSTRACTThe measures to control the COVID-19 pandemic in the academic 2020/2021 included full-time online courses for medical students in Serbia for the first time since the faculty was founded in 1920. The purpose of this study was to examine the attitudes and opinions about the full-time online course among medical students and their teachers. A qualitative study was carried out in the autumn of 2021. In-depth interviews were conducted with 38 participants (27 students in the 4th study year and 11 teachers who teach in the 3rd study year) about their experiences in the past academic year. To select study participants, purposive sampling was employed. The interviews were audio-recorded and transcribed verbatim. Qualitative content analysis was applied. Five topics emerged: 1) Theoretical online learning, 2) Practical online learning, 3) Motivation, 4) Technical aspects of online learning and 5) Evaluation of knowledge. Overall, students’ attitudes toward theoretical classes were mostly negative, but the attitudes of teachers were mostly positive. However, the attitudes of both students and teachers toward practical online classes were mostly negative. Students were, in general, less motivated to follow online classes compared to conventional courses, even though the teachers felt that they had to put more effort into making a suitable online course. Most participants considered that the online classes had a negative impact on their knowledge and practical skills, but their academic achievement was not inferior compared to previous years. The full-time online course should include conventional on-site teaching. The relevance of acquiring practical skills is strongly emphasized
