Article Synopsis
  • Brucellosis is a sickness caused by bacteria that affects both people and animals, causing health problems and money loss in farming in Türkiye and other countries.
  • Researchers studied the genes of 106 samples from animals and humans in Türkiye to understand how they differ from each other and from samples in other countries.
  • The study found different types of the bacteria in Türkiye, showing they are also related to bacteria from neighboring countries and some European countries, which means travel might help spread the disease, so better controls are needed to keep it from spreading.

The aim of this study was to develop a multiplex PCR assay capable of rapidly differentiating two major (APV) species, (FWPV) and (PGPV), which cause disease in bird species. Despite the importance of a rapid differentiation assay, no such assay exists that can differentiate the APV species without sequencing. To achieve this, species-specific target DNA fragments were selected from the fpv122 gene of FWPV and the HM89_gp120 gene of PGPV, which are unique to each genome.

Rhodococcus equi is a common cause of pneumonia in foals and has extensive clinical, economic and possibly zoonotic consequences. This bacterium survives well in the environment and may be considered as normal flora of adult horses. Certain strains of this bacterium are extremely virulent in foals, and early identification and intervention is crucial for prognosis.

In this study, Staphylococcus aureus strains (n = 110) isolated from seven ewe flocks in Sanliurfa, Turkey were screened for antibiotic resistance and biofilmforming ability as well as for genes associated with antibiotic resistance and biofilm-forming ability. All isolates were found to be susceptible to oxacillin, gentamicin, clindamycin, cefoxitin, tetracycline, vancomycin, amoxicillin-clavulanic acid, ciprofloxacin and sulphamethoxazole-trimethoprim. The percent proportions of strains resistant to penicillin G, ampicillin and erythromycin were 27.
