Molecular characterization of Irish Salmonella enterica serotype Typhimurium: detection of class I integrons and assessment of genetic relationships by DNA amplification fingerprinting

Article Abstract:

Results show that Salmonella enterica serotype Typhimurium DT104 are resistant to antimicrobials and integrons play a role in the dissemination of antimicrobial resistance genes. Data indicate that DT104 isolates exhibit a high degree of homogeneity at a molecular level.

Clonal expansion may account for high levels of quinolone resistance in Salmonella enterica serovar enteritidis

Article Abstract:

A group of nalidixic acid-resistant and nalidixic acid-susceptible isolates of serovar Enteritidis from multiple sites in Ireland were observed. Isolates were typed by pulsed-field gel electrophoresis (PFGE) with XbaI, and the MICs for nalidixic acid and ciprofloxacin were determined.

Molecular analysis of Pseudomonas aeruginosa: epidemiological investigation of mastitis outbreaks in Irish dairy herds

Article Abstract:

The existence of Pseudomonas aeruginosa in teat wipes was found to be the predominant cause of the mastitis outbreak that plagued 11 dairy herds in Ireland. Clinical isolate results gathered by Cork University Hospital researchers revealed that 35 among 36 strains manifested genetic patterns similar to the Cla1 and PvuII bacteria, which is a potent cause of mastitis both in humans and animals. These strains were further found to possess low-molecular weight polymorphisms.
