The drinking water cycle consists of the stages untreated water, potable and sewage. Escherichia coli is considered an indicator fecal contamination since it a common bacterium intestinal flora humans warm-blooded animals carrier many antibiotic resistance genes. aim this investigation was to assess level drug coliforms E. isolates in samples submitted from various sites Central South Greece during period 2018–2022. highest rates among both coliform were observed against ampicillin. analysis...

Background/Objectives: Over the past decade, extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli have emerged as a significant public health concern due to their potential spread beyond clinical settings and healthy carriers, in various environments, including animal source foods. This study seeks investigate molecular characteristics of ESBL-producing E. strains isolated from food origin, with focus on chromosomal typing, plasmid description associated resistance genes’...

Background and Aim: Canine degenerative myelopathy (CDM) is an adult-onset fatal disorder associated with a point mutation of the superoxide dismutase 1 (SOD1) gene (SOD1:c.118G>A). This study aimed to determine allele genotype frequencies this in group Belgian Malinois dogs Greece. Materials Methods: Samples (n=72) whole blood were collected from 72 purebred Hellenic Armed Forces; these samples processed for DNA isolation, polymerase chain reaction, digestion restriction endonuclease...

Recently, we investigated the spread of antimicrobial drug-resistant (AMR) microorganisms in five dairy sheep farms Greece to identify indicators for improved field surveillance. The high percentage samples feeds and milk positive Escherichia coli Staphylococci, including AMR isolates, recorded this previous study generated interest further investigate parameters likely affect positivity these certain same farms. For reason, 76 were collected, comprising collected from raw tank (n = 5),...
