1. E. coli is an opportunist pathogen of animals, including food-producing ones and humans. Chickens may be a notable source pathogenic antimicrobial resistant for transmission to
Salmonellosis caused by Salmonella agents is the second most common zoonotic infection in humans. In recent years, Salmonella's increasing antimicrobial resistance (AMR) has been a concern. The major transmission route of consumption contaminated poultry products. Therefore, monitoring chicken-originated critically important. This study investigated AMR four commonly isolated serovars from chickens, namely Enteritidis (S. Enteritidis), Infantis Infantis), Kentucky Kentucky), and Typhimurium...
To assess the antibiotic resistance, transposon profiles, serotype distribution and vaccine coverage rates in 110 erythromycin-resistant S. pneumoniae clinical isolates.Erythromycin, clindamycin, tetracycline, chloramphenicol kanamycin susceptibilities were assessed using E-test/disc diffusion method. Inducible macrolide resistance was tested erythromycin-clindamycin double disc test. Serogrouping serotyping performed latex particle agglutination Quellung reaction, respectively. Drug genes...
Burkholderia spp. emerged as important pathogens in the airways of immunocompromised humans, especially those with cystic fibrosis (CF). Failure identification conventional techniques, high intrinsic resistance to most antibiotics and biofilm formation can cause difficulties treatment these infections. The aim this study was identify strains isolated from CF non-CF patients routine microbiological methods, matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF...
Foodborne infections due to Salmonella are still a major concern worldwide. Particularly contaminated egg and related products the primary sources for human salmonellosis. It is necessary determine risk factors associated with contamination of eggs within scope farm table environment. The objective this study was develop "National Control Program in Laying Hens" report prevalence serotype distribution findings laying hens Turkey. A total 2122 samples were collected analysed according ISO...
Abstract Proteus mirabilis is a common enteric bacterium in livestock and humans. The increase spread of the antimicrobial resistant P. considered alarming worldwide. Transmission mainly occurs through consumption contaminated poultry products. We investigated resistance (AMR) virulence markers broiler chicken-originated isolates from 380 fecal samples. Phenotypic AMR test was performed against seventeen different antimicrobials. Genotypic to detect sixteen genes. samples were also tested...
Fowl aviadenoviruses (FAdVs) are widely distributed among poultry populations, leading to various diseases, immunosuppression, and economic losses. Molecular characterization phylogenetic analysis of circulating FAdV isolates play a critical role in epidemiologic studies, contributing the control, monitoring, prevention related outbreaks. This study aimed determine serotypes reveal molecular epidemiology broiler chicken flocks. Samples were taken based on epidemiologically important...
Bu çalışmada broyler tavuk kümeslerinin altlık, toz, çevresel, kemirici kapanları, yem ve su örneklerinden izole edilen 20 adet Salmonella Infantis suşunun multilokus dizi tiplendirme (MLST) ile tiplendirilmesi amaçlandı. Sekans tipleri (ST) serotipler arasındaki evrimsel ilişkiyi göstermek amacıyla yapılan filogenetik analizde, 6 farklı serotip çalışmaya dahil edildi. Her bir suşa ait 7 housekeeping gen üzerinden gerçekleştirilen MLST analizi sonucunda tüm S. suşları ST32 bulundu Türkiye'de...
In this study, 61 Staphylococcus pseudintermedius strains were isolated from 77 dogs with skin infections. Antimicrobial resistance to commonly used antibiotics was evaluated by disc diffusion method. The presence of the blaZ and mecA genes responsible respectively for penicillin methicillin investigated PCR. S. isolates highly resistant tetracycline (47.5%) (40.9%) while all susceptible amikacin (100%). All 18 methicillin-resistant (MRSP) positive gene 25 strain also phenotypically. Of MRSP...
In this study, it was aimed to determine the effects of using UV light instead formaldehyde in disinfection hatching eggs on microbial load, shell and yolk compositions, embryo development, results chick characteristics. 552 were divided into fumigation with groups. After disinfection, bacteriological growth not observed While difference between groups terms insignificant, determined that incubation period group shorter than group. On day, relative weight bursa Fabricus found be higher . can...
Bu derlemede; filogenetik bilimi ve esasları, temel terminolojisi, ağaç gösterim şekilleri hakkında bilgi verilip, bir analizde izlenmesi gereken adımlar anlatıldı. Analizde kullanılacak verinin taşıması başlıca kriterler, veri tabanlarından referans birimlerin elde edilmesi genlerin analiz süreci ele alındı. Filogenetik oluşturmada kullanılan bilgisayar tabanlı metotların özellikleri üstünlükleri belirtildi. Analiz sonucu edilen ağacın güvenilirliği bu değerin yorumlanması üzerinde duruldu....
The aim of this study was to compare gold standard conventional culture method and internal transcribed spacer (ITS) sequence-based analysis in the identification fungi isolated from domestic animals.A total 35 animals (15 cats, 11 dogs, 4 horses 5 chickens) suspected for fungal infection were examined.Of samples, 20 found be positive culture.Among samples 8 (40%) predominantly dermatophyte species by methods.The ITS regions (ITS1, ITS2 complete ITS) isolates also amplified, sequenced...
Salmonellosis caused by nontyphoidal Salmonella is the second most common zoonotic infection worldwide. The major foodborne route of this consumption contaminated poultry meat and egg. Therefore, monitoring control agents in populations critical to reduce risks for public health. In industry, serotypes infections are enterica subsp. serotype Enteritidis Typhimurium. recent years, other frequently isolated have also increased Turkey because programs regulated many countries. Hence, (except...
Mastitis is one of the most common infections worldwide.This infection poses risks to animal and public health.Therefore, determination mastitis pathogens important for prevention infection.Generally, combination antimicrobials an effective, reliable treatment approach.In this study, it was aimed determine bacterial in goat's milk antimicrobial resistance profiles these pathogens.A total 190 goat samples were examined with standard microbiological analysis period 2018-2019.Bacterial obtained...
Salmonella Enteritidis and Typhimurium are the most common serovars observed in human salmonellosis while contaminated poultry products major source of transmission to humans. Therefore, high pathogenicity originated S. strains poses a serious risk health. In this study, we investigated virulence genes isolated from litter environmental samples broiler chicken flocks. SipA, sipD, sopB, sopD, sopE, sopE2, sitC, sifA, ssaR, spvC, pefA were total 137 consisting 105 32 Typhimurium. Nine (6.6%)...
It is important for public health to monitor infectious agents in domestic animals. This study aimed detect of bacterial and fungal the skin various A total 263 samples were collected during 2021-2023 from 147 cats, 102 dogs, 10 cows, 3 rabbits, 1 iguana. Bacteriological examination indicated that 37.6% positive. S. pseudintermedius (35.4%) was dominant bacteria all isolates, followed by P. aeruginosa (23.2%). aureus isolated one rabbit sample iguana sample. These findings add limited number...
This study investigated five strains of each serotype Salmonella Agona, Heidelberg, Hindmarsh, Kouka, Muenchen, Ottmarchen, Saintpaul and II, isolated during the 2014-2017 period.

Kouka resistant serotypes were Agona Heidelberg. MDR frequently in strains, followed Saintpaul, Hindmarsch, Ottmarchen. samples susceptible...
Background: Burkholderia spp. are problematic infectious agents for cystic fibrosis (CF) or chronic granulomatous disease patients. Due to the failure of identification with conventional techniques and high intrinsic resistance most antibiotics, these infections very difficult treat can cause a marked reduction in life expectancy. The aim this study was identify strains isolated from CF non-CF patients multilocus sequence analysis (MLSA). Also, antibiotic synergies antibiotics were...
Abstract In this study, Salmonella Enteritidis strains isolated from dust and environmental materials different flocks located in Turkey’s Western Black Sea region were examined by pulsed field gel electrophoresis (PFGE) multilocus sequence typing (MLST). A total of 59 S . broiler breeder hatchery flocks, one strain a stool sample farm worker examined. PFGE analysis revealed two major groups nine macro restriction profiles. It was determined that 85% (51/60) the close to each other comprised...
