Migratory birds along the Mediterranean – Black Sea Flyway as carriers of zoonotic pathogens
In this study, bird species migrating through Bulgaria were investigated as carriers of zoonotic pathogens. In total, 706 birds belonging to 46 species were checked for the presence of various bacterial pathogens (Campylobacter, Yersin ia, Salmonella, Listeria, Escherichia coli, Staphylococcus aureus, Francisella tularensis, Coxiella burnetii, Borrelia burgdorferi, and Brucella spp.). From 673 birds we investigated fecal samples, from the remaining 33, blood samples. We detected Campylobacter 16S rDNA gene in 1.3% of birds, but no ne were of pathogenic Campylobacter jejuni and Campylobacter coli species. Escherichia coli 16S rDNA gene was found in 8.8% of the birds. Out of 34 birds that transported Yersinia enterocolitica strains (5.05%), only 1 carried a pathogenic isolate. Three birds (0.4%) were carriers of nonpathogenic S almonella strains. Four avian samples (0.6%) were positive for Listeria monocytogenes and 1 (0.15%) was positive for Brucella spp. None of the birds tested carried the tick-borne pathogens C. burnetii or B. burgdorferi sensu lato. Antibiotic-resistant strains were detected, suggesting that migratory birds could be reservoirs and spreaders of bacterial pathogens as well as antibiotic resistance genes.

(Canadian Medical Association Journal) A new guideline from the Canadian Task Force on Preventive Health Care, based on a rigorous systematic review of the latest evidence, found no benefit of routine screening for esophageal adenocarcinoma (EAC) and precursor conditions (Barrett esophagus and dysplasia) in patients with chronic gastroesophageal reflux disease (GERD). The guideline, published in CMAJ (Canadian Medical Association Journal), recommends physicians in Canada continue current practice to not screen routinely http://www.cmaj.ca/lookup/doi/10.1503/cmaj.190814.

(Rutgers University) Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research&Technology, examined the microbe-laden " biofilms " that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
