A newly uncovered parvovirus, Chaphamaparvovirus, continues to be reported across various species. This study investigated the detection and genetic characterization of Chaphamaparvovirus galliform (GaChpV) in poultry, specifically broilers turkeys, from regions Türkiye. To address this, comprehensive sampling analysis were conducted better understand virus's distribution impact these avian populations. In 2023, a total 1060 fecal samples collected 76 broiler flocks (10 healthy 66 with...

A case of aspergillosis in a broiler breeder flock having respiratory and nervous system problems caused by Aspergillus fumigatus niger is documented. Dyspnea, hyperpnea, blindness, torticollis, lack equilibrium, stunting were observed clinically. On postmortem examination the affected birds, white to yellow caseous nodules on lungs, thoracic air sacs, eyes, cerebellum. Histopathologic lungs cerebellum revealed classic granulomatous inflammation cerebellar lesions, necrotic...

Aims: The objectives of this study were to determine the presence thermophilic Campylobacter spp. in free range domestic geese, and characterize isolated strains using phenotyping criteria SDS-PAGE whole-cell proteins. Methods Results: Forty cloacal swabs from two different flocks geese examined. All Camp. jejuni biotyped Lior biotyping scheme. Twelve isolates also tested for their susceptibility 17 antibacterial agents by a disc diffusion method. Fourteen subjected SDS-PAGE. examined found...

1. In this study, the effect of chlorogenic acid extract from Lonicera japonica Thunb. on Mycoplasma gallisepticum infections and performance broiler flocks was investigated. 2. A total 360 Ross-308 chicks taken M. seropositive were divided equally into three groups designated as control (nothing administered), antibiotic (Tylosin tartrate given for first 3 d 20-22) test group (chlorogenic twice a day 16 22). 3. Broiler analysis, serological tests (slide agglutination), molecular...

The in vitro susceptibilities of Pasteurella haemolytica biotypes A and T P multocida from pneumonic ovine lungs to penicillin, ampicillin, oxytetracycline, chloramphenicol, erythromycin, kanamycin, neomycin, gentamicin, streptomycin lincomycin were determined by the disk diffusion method. All isolates sensitive chloramphenicol resistant lincomycin. biotype consistently more erythromycin than those T.

To assess whether Candida species can penetrate intact fetal membranes under in vitro conditions, albicans, tropicalis, guil-liermondii, pseudotropicalis and glabrata were inoculated onto the surface of maternal side obtained from 4 pregnant women undergoing repeat cesarean section. After incubation culture evaluated by histological examination. C. albicans penetrated passed to caused some degeneration structure membrane epithelium. The other four grew heavily on but did not invade...

The relationship of 50 Campylobacter strains isolated from aborted ovine foetuses, and the faeces sheep, cattle chickens were determined by numerical analysis electrophoretic (SDS-PAGE) protein profiles. Comparison patterns methods revealed differences between C. fetus ssp. fetus, jejuni, coli as well heterogeneity among isolates different outbreaks. Isolates each farm produced a distinct cluster flocks locations found to be infected with relatively strains. In most cases, foetal very...

The purpose of the present study was to investigate presence pathogenic mycoplasma species in turkey population Turkey. Tracheal samples randomly collected from a total 624 apparently healthy meat-type turkeys at commercial abattoir located north country were examined by culture and genus- species-specific polymerase chain reaction (PCR) assays for mycoplasma. In direct plating onto solid specific media, growth observed 1.4% (9/624) samples, which confirmed belong Mycoplasma genus...

Infectious laryngotracheitis (ILT) is a very serious respiratory disease of poultry all over the world. For last decade, many countries have reported ILT disease. However, there no report about in broiler breeders Turkey. In this study, we investigated on farm purpose, five samples were from twenty-eight week old farm, which consists 5 flocks with 34.500 breeders. The presence virus was determined by PCR targeting ICP4 gene (infected-cell polypeptide 4) and characterized sequencing. This first Turkey
