Characterization of Strains Isolated from Various Poultry Species in Poland.

() is one of the common pathogens found in poultry flocks, resulting in serious economic losses for the poultry industry due to high mortality, reduced growth rate, poor feed conversion, increased condemnations, and high treatment costs. The aim of this study was to phenotypically characterize phylogenetic relationships and assess the presence of resistance gene strains of obtained from various poultry species in Poland. A total of 57 isolates of were included in this study.

Determination of Anti-phage Antibodies in Calf Sera Following Application of and -specific Bacteriophages.

Introduction: The widespread occurrence of drug-resistant bacteria has increased interest in alternatives to antibiotics for combatting bacterial infections, among which bacteriophages play an important role. The ability of phage proteins to induce an anti-phage immune response can significantly limit the effectiveness of treatment, which was the basis for the study described in this article. The aim of the study was to assess the effects of bacteriophages on the induction of an anti-phage humoral response in calves.

Antibiotic Resistance and Virulence Profiles of Strains Isolated from Wild Birds in Poland.

Wild animals are increasingly reported as carriers of antibiotic-resistant and pathogenic bacteria including . However, the role of free-living birds as reservoirs for potentially dangerous microbes is not yet thoroughly understood. In our work, we examined strains from wild birds in Poland in relation to their antimicrobial agents susceptibility, virulence and phylogenetic affiliation.

Therapeutic and Prophylactic Effect of the Experimental Bacteriophage Treatment to Control Diarrhea Caused by in Newborn Calves.

The prevalence of antibiotic-resistant bacteria causing neonatal diarrhea in calves has become a serious problem in the control of infection. Due to increasing antibiotic resistance, bacteriophages with probiotics are considered the best alternative. The aim of the study was to evaluate the use of a suppository containing probiotic strains of spp.

Biofilm-Formation Ability and the Presence of Adhesion Genes in Coagulase-Negative Staphylococci Isolates from Chicken Broilers.

The aim of the study was to analyze the biofilm-production capacity of 87 coagulase-negative strains (CoNS) isolated from broiler chickens and to determine the occurrence of biofilm-associated genes. The biofilm production capacity of staphylococci was assessed using the microtiter plate method (MTP), and the frequency of genes was determined by PCR. The ability to form a biofilm in vitro was shown in 79.

The in vitro efficacy of eye drops containing a bacteriophage solution specific for Staphylococcus spp. isolated from dogs with bacterial conjunctivitis.

Background: The purpose of the study was to evaluate the in vitro antibacterial effect of experimental eye drops with bacteriophages in elimination of Staphylococcus spp. isolated from dogs with bacterial conjunctivitis..

Phenotypic and genotypic antimicrobial resistance profiles of fecal lactobacilli from domesticated pigeons in Poland.

Lactobacillus species play an important role in the host and although they are non-pathogenic, they could act as reservoirs for antibiotic resistance genes, with the potential risk of transfer to other bacteria inhabiting the gastrointestinal tract. The aim of this study was to identify Lactobacillus species derived from feces of domesticated pigeons and to characterize their phenotypic and genotypic antimicrobial resistance (AMR) profiles. A total of 57 Lactobacillus isolates were classified into six species using the MALDI-TOF technique and 16S rDNA restriction analysis.

Campylobacter spp. and bacteriophages from broiler chickens: Characterization of antibiotic susceptibility profiles and lytic bacteriophages.

Bacteria of the genus Campylobacter are the most common pathogens causing zoonotic diseases in humans. Therefore, the aim of the study was to isolate Campylobacter bacteria from broiler chickens and evaluate their susceptibility to selected antibiotics by determining minimum inhibitory concentrations (MIC), followed by isolation and characterization of bacteriophages specific for Campylobacter spp. The material for the study consisted of field isolates of Campylobacter spp.

Identification and antibiotic susceptibility of lactobacilli isolated from turkeys.

Background: The aim of this study was to identify Lactobacillus isolates derived from turkeys from six Polish farms and to characterize their phenotypic and genotypic antibiotic resistance profiles.

Results: Among 62 isolates identified by MALDI-TOF mass spectrometry and restriction analysis of 16S rDNA, the dominant species was L. salivarius (35%), followed by L.

Protein profiles of bacteriophages of the family Myoviridae-like induced on M. haemolytica.

The aim of study was to isolate, characterize and analyse the protein profiles of Myoviridae-like bacteriophages obtained from M. haemolytica using MALDI TOF mass spectrometry. The material consisted of the M.

Probiotic potential of Lactobacillus isolates of chicken origin with anti-Campylobacter activity.

Campylobacteriosis is currently the most frequent zoonosis in humans and the main source of infection is contaminated poultry meat. As chickens are a natural host for Campylobacter species, one strategy to prevent infection in humans is to eliminate these bacteria on poultry farms. A study was conducted to evaluate the probiotic potential of 46 Lactobacillus isolates from chickens faeces or cloacae.

WILD BIRDS AS A POTENTIAL SOURCE OF KNOWN AND NOVEL MULTILOCUS SEQUENCE TYPES OF ANTIBIOTIC-RESISTANT ENTEROCOCCUS FAECALIS.

We assessed the antibiotic resistance and genetic diversity of 27 Enterococcus faecalis isolates from 25 wild bird species in Poland. Resistance to lincomycin (100%) was most common followed by tetracycline (48%), erythromycin (44%), and ciprofloxacin (22%). High-level resistance to streptomycin and kanamycin was observed in 19% and 15% of isolates, respectively.

Bacteriophage therapy to combat bacterial infections in poultry.

Infections in poultry are an economic and health problem in Europe and worldwide. The most common infections are associated with salmonellosis, colibacillosis, campylobacteriosis, and others. The prevalence of Campylobacter-positive poultry flocks in European countries varies from 18% to 90%.

Antimicrobial activity of Lactobacillus strains of chicken origin against bacterial pathogenss.

This study was conducted to identify and evaluate the antimicrobial activity of some Lactobacillus isolates of chicken origin. Among 90 isolates 14 Lactobacillus species were distinguished using MALDI-TOF mass spectrometry and 16S-ARDRA. The dominant species was L.
