11. Exploring the Epidemiology and Population Structure of Campylobacter jejuni in Humans, Broilers and Wild Birds
Sammanfattning : .... LÄS MER
12. Molecular detection and epidemiological studies of atypical bacteria causing respiratory tract infections
Sammanfattning : Respiratory infections are common causes of morbidity and mortality. Chlamydia pneumoniae, Mycoplasma pneumoniae and Bordetella pertussis cause respiratory infection, often with similar symptoms. Molecular diagnostic methods are preferred since these bacteria are difficult to culture. LÄS MER
13. Antimicrobial Resistance and Production of Extended Spectrum Beta-Lactamases in Enterobacteriaceae from Birds in Bangladesh
Sammanfattning : The dissemination of members of the Enterobacteriaceae family with extended spectrum beta-lactamases (ESBLs) and metallo-beta-lactamases (MBLs) has become a global concern. ESBLs and MBLs have been reported in humans, domestic animals, wildlife and the environment, and their isolation frequencies are increasing rapidly worldwide. LÄS MER
14. Human Pathogens and Antibiotic Resistant Bacteria in Polar Regions
Sammanfattning : Coincident with human activity in recent decades, human-associated microorganisms have arrived to the Antarctic region, possibly linked to increasing presence of scientific bases and ship-borne tourists. In the Arctic, humans have been present for a very long time, and the few parts of the Arctic without human activities is decreasing with time. LÄS MER
15. Dispersal of ticks and their microorganisms by African-Western Palaearctic migratory birds
Sammanfattning : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.
