Carbapenem-Resistant KPC- And TEM-Producing Escherichia coli ST131 Isolated from a Hospitalized Patient with Urinary Tract Infection: First Isolation in Molise Region, Central Italy, July 2018

In July 2018, a Klebsiella pneumoniae carbapenemase (KPC)-producing Escherichia coli ST131 was isolated from a patient admitted to the Vascular Surgery Unit of the main hospital of Molise region, Central Italy. Sequencing and alignment with the available sequences revealed that the isolate harbored the KPC-2 variant and TEM-1 beta-lactamase. This observation raises great concerns about the spread of carbapenem resistance in national and local settings with high endemicity level of KPC in K. pneumoniae, and underlines the importance of strengthening a proactive surveillance

Prevalence of Salmonellae, Listeriae, and Yersiniae in the Slaughterhouse Environment and on Work Surfaces, Equipment, and Workers

In 1995 and 1996 a nine-month study was carried out in 11 pig abattoirs located in the Molise region (Italy) to evaluate the degree of contamination of- the slaughterhouse environment, work surfaces, equipment, and personnel by Salmonella spp., Listeria spp., and Yersinia spp. A total of 219 samples were taken over three replications including slaughtering floor and wall, hooks, work-tables, chopping blocks, knives, cleavers, dehairing devices, hands of personnel, clothing, hand-wash basins, and cold room handles, floor, wall, and hooks. Overall, six abattoirs (54.5%) had one or more positive sites, while only 14 of the 219 sites (6.4%) tested were positive for any of considered microorganisms. Salmonella spp. were isolated from 1 of 9 cleavers (11.1 %), 1 of 16 worktables (6.25%), and 1 of 18 slaughtering floors (5.6%). Yersinia enterocolitica was found on 3 slaughtering floors (16.7%) and on 2 worktables (12.5%). Yersinia kristensenii was detected on 2 slaughtering floor swabs (11.1 %). Listeria monocytogenes was isolated from 2 of 20 cold room floor swabs (13.3%) and from 1 of 14 hand-wash basins (7.1%). Other species of Listeria were detected on slaughtering wall and floor swabs and on chopping blocks. Our study indicates that slaughtering floors, cold room floors, and worktables are important sites in abattoirs that may possibly harbor pathogens like Salmonella spp., Yersinia enterocolitica , and Listeria monocytogenes , and that cleaning and sanitizing of the slaughterhouse environment and equipment need a greater emphasis

Prevalence and biomolecular characterization of Campylobacter spp. isolated from retail meat.

We estimated the prevalence of Campylobacter spp. in retail meat (n = 352 samples; 104 chicken, 106 pork, and 142 beef) collected in Campobasso, Italy, comparing two microbiological methods. All the isolates were characterized by biomolecular techniques for epidemiological purposes. Campylobacter isolation was performed by selective culture and membrane filtration methods. Phenotypic and genotypic methods for genus and species identification were evaluated together with antimicrobial resistance and plasmid profiling. Sixty-nine (86.2%) samples were positive by selective culture, 49 (61.2%) by membrane filtration, and 38 (47.5%) by both methods. Only 74 of 80 strains were confirmed as Campylobacter spp. by PCR, and two Campylobacter coli were identified as Campylobacter jejuni . Chicken meat was more frequently contaminated than other meats. Selective culture was more sensitive than membrane filtration (85 versus 66%), and specificity of the methods was 98 and 100%, respectively. Among Campylobacter isolates from chicken meat, 86.5% were multidrug resistant. Resistance to ciprofloxacin (51.3%) and enrofloxacin (52.7%) was lower than to nalidixic acid (71.6%). C. coli strains showed the highest cross-resistance for quinolones (82.6%) and fluoroquinolones (60.9%) as well as a high resistance to tetracycline. Plasmids were isolated from six C. coli and two C. jejuni isolates, but no association was detected between antimicrobial resistance and plasmid DNA carriage. Selective culture is considered as the optimal method for Campylobacter isolation, although it was unable to detect all contaminated samples. Membrane filtration provided more specific results but with low sensitivity. A combination of both techniques may offer better results
