Assessment of Bacterial Contamination and Antimicrobial Resistance of Isolates from Slovak Dairy Farms.

The conditions in livestock housing are suitable for the survival of airborne microorganisms, mainly due to high temperatures, humidity, and the presence of organic material. The total count of airborne bacteria concentrations in cattle farms ranged from 3.01 log CFU/mL to 6.

Devitalization of Bacteria in Composted Cattle Manure with Natural Additives and Risk for Environment.

Nowadays, there is an effort to improve the effectiveness of the composting process, supported by the addition of various supplements to reduce soil nutrition losses and increase soil remediation. The aim of this study was to examine the devitalization effect of natural additives like zeolite-clinoptilolite and its combination with hydrated lime in composted cattle manure on indicator and pathogen bacteria. The composting process was running in three static piles of cattle manure mixed with wheat straw (control, zeolite-lime, and zeolite) for 126 days.

Effect of Wastewater Treatment on Bacterial Community, Antibiotic-Resistant Bacteria and Endoparasites.

Wastewater and wastewater treatment plants serve as urban reservoirs of pathogenic microorganisms. Wastewaters frequently contain bacteria, antibiotic-resistant bacteria, and developmental stages of parasites with significant zoonotic potential. Five wastewater treatment plants in the central part of Slovakia were investigated to determine the effect of treatment on bacterial community, antibiotic-resistant bacteria, and the occurrence of helminth eggs.

Antimicrobial Resistance of sp. Isolated from Cheeses.

and some species of coagulase-negative staphylococci, including , commonly cause intramammary infections. However, little attention was paid to the antimicrobial resistance of these species with respect to their occurrence in dairy products, for example, popular sheep and goat cheeses made from unpasteurized milk. The aim of this study was to investigate such sheep and goat cheeses for the occurrence and antimicrobial resistance of the relevant staphylococci species.

New Insight on Antibiotic Resistance and Virulence of from Municipal and Animal Wastewater.

Antibiotic resistance of the indicator microorganism was investigated in isolates from samples collected during the course of one year from two wastewater treatment plants treating municipal and animal wastes in Slovakia, respectively. The genes of antibiotic resistance and virulence factors in selected resistant isolates were described. A high percentage of the isolates from municipal and animal wastewater were resistant to ampicillin, streptomycin, tetracycline, ceftiofur, ceftriaxone, and enrofloxacin.

Detection of Antimicrobial Resistance of Bacteria Isolated from Sheep's Milk and Cheese.

Antimicrobial and multidrug resistance is detected in nonaureus staphylococci, including , which commonly causes intramammary infections. Recent clinical studies point to the presence of methicillin-resistant Therefore, this study aims to determine the prevalence of this species in samples of sheep's milk and cheeses made from them. Isolates were identified by polymerase chain reaction and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF).

Comparison of spp. and flock health indicators of broilers in Iceland.

Introduction: The safety of poultry meat products and contamination with microorganisms is based on appropriate reduction of the presence of pathogens during poultry rearing and is closely related to the level of rearing hygiene, including the type of housing, stocking density, microclimate, sanitation and ventilation.

Objective: The aim of the study is to evaluate the prevalence of -positive samples in Iceland during 2016-2018, and to compare the potential influence of individual parameters of welfare on the prevalence of spp.

Material And Methods: Positivity of excrement and caecum samples for spp.

Antibiotic resistance and virulence of Escherichia coli strains isolated from animal rendering plant.

Processing of animal carcasses and other animal wastes in rendering plants is a significant source of antibiotic resistant microorganisms. The main goal of this study was to investigate the resistance to 18 antibacterial agents including β-lactams, fluoroquinolones, colistin and virulence factors (iss, tsh, cvaC, iutA, papC, kps and ibeA genes) in 88 Escherichia coli strains isolated from a rendering plant over 1 year period. ESBL (Extended-spectrum beta-lactamases) and plasmid-mediated Amp were screened by interpretative reading of MIC.

Devitalisation of pathogens in stored pig slurry and potential risk related to its application to agricultural soil.

The study investigated the risks arising from application of pig slurry to soil in relation to viability of Salmonella typhimurium, Escherichia coli, total coliforms, faecal enterococci and eggs of Ascaris suum at different temperatures. Potential effect of changes in physico-chemical parameters, particularly dry matter (DM), pH and ammonia, were also investigated. Examination showed that S.

Extended spectrum beta-lactamases in Escherichia coli from municipal wastewater.

Introduction And Objective: Over the past decades, awareness of the environmental load of resistant organisms has increased. The presented paper focuses on antibiotic resistance and detection of resistance genes in environmental E. coli and on the evaluation of biofilm formation in ESBLs (extended spectrum beta-lactamase) producing E.

Antibiotic resistance of Escherichia coli isolated from a poultry slaughterhouse.

The aim of the study was to investigate the antibiotic resistant E. coli strains isolated from bioaerosols and surface swabs in a slaughterhouse as a possible source of poultry meat contamination. The highest air coliforms contamination was during shackling, killing and evisceration of poultry.
