Turkish Journal of Veterinary & Animal Sciences
Psittacine beak and feather disease virus (PBFDV) is a significant viral pathogen affecting the development of beak and feather cells, leading to feather abnormalities in avian species. This study aimed to investigate the molecular detection rate of PBFDV among Psittaciformes in Iran and to evaluate the influence of factors such as sex, species, season, and bird origin on PBFDV prevalence. Feather samples were collected from 1335 Psittaciformes, including Agapornis roseicollis, Pyrrhura molinae, Myiopsitta monachus, Aratinga solstitialis, Nymphicus hollandicus, Psittacula krameri, Psittacus erithacus, Poicephalus senegalus, Eos bornea, and Agapornis fischeri, and subjected to polymerase chain reaction (PCR) for PBFDV detection.

Prevalence Of Carriers Of Cholesterol Deficiency–Associated Apob Mutation In Some Native, Holstein And Simmental Cattle Breeds In Türkiye, Hasan Meydan, Kübra Bedi̇r Di̇bi̇ç, Onur Vural, Mehmet Ali̇ Yildiz, Jørgen S. Agerholm
Turkish Journal of Veterinary & Animal Sciences
Genetic diseases play an increasingly important role in cattle breeding as breeding technologies such as artificial insemination has an inborn risk of disseminating deleterious genes, especially from high merit breeding sires. Cholesterol deficiency (CD) is a metabolic disorder first recognized in Holstein cattle in 2015. The condition is characterized by chronic diarrhea and unthriftiness in calves being homozygous for the defective allele. The prevalence of carriers of CD in Turkish cattle is at present unknown and therefore 700 heifers and cows of different breeds, including 300 Holsteins were genotyped. Of the tested Holsteins, 2.0% turned out to be carriers of …

Evaluation Of Larval Culture And Conventional Pcr Methods For The Detection Ofstrongylus Vulgaris In Equines Of Iran, Alireza Alborzi, Sara Larki, Abbas Zeinali
Turkish Journal of Veterinary & Animal Sciences
Strongylus vulgaris (S. vulgaris) is known as the equin's most pathogenic nematode due to the extraintestinal migration in mesenteric arterial vessels. Since a few kinds of S. vulgaris can threat the animals' health and working efficiency, high precision and early detection of strongylid nematodes is essential. Traditionally, the larval coproculture method was used frequently for identification of strongylid species. The technique of larval culture is costly, time consuming, and does not have sufficient accuracy and reliability. Here, we critically evaluated the polymerase chain reaction (PCR) with larval culture methods for the detection of S. vulgaris eggs in fecal samples. To …

In Silico Design And In Vitro Development Of A Highly Accurate Test To Detect Brucella Species, Hosein Safari, Setareh Shahnazari, Maysam Mard-Soltani, Somayeh Tavakoli, Bahman Khalesi
Turkish Journal of Medical Sciences
Background: Conventionalmethods of detecting Brucella spp. suffer from technical and biological complications. Besides, newly characterized species of the genus Brucella could be neglected by previously designed polymerase chain reaction (PCR) tests. Therefore, a more accurate PCR-based test seems to be imminently needed. Materials and methods: Blood samples were collected from 39 patients diagnosed with brucellosis and 25 healthy controls. Multiple sequence alignments (MSA) were performed on 500 Omp2-related protein and gene sequences. Thereafter, specific primers were designed and synthesized for the regions with highest conservancy. The collected samples were assessed by PCR test. To overcome the cross-reactivity issue, PCR thermal …

Turkish Journal of Veterinary & Animal Sciences
Sarcocystis species are the most commonly encountered parasitic organisms in animals. Sarcocystis hominis (Sarcocystis bovihominis), the species found in beef cattle, is not visible macroscopically in muscle tissue. In recent years it has been established that, in addition to being a zoonotic parasite transmitted via the consumption of beef, the parasite produces toxins and causes food poisoning. Therefore, this study was undertaken in order to determine the extent to which Sarcocystis species are present in minced meat, meatballs, and fermented sausages produced from beef and marketed in Kars. A total of 150 samples, 50 of each product, were collected in …

Background/aim: Adenoid hypertrophy (AH) is chronic enlargement of the adenoid tissue. The pathophysiology of the disease is unclear. We analyzed SCGB1D4 gene polymorphisms in order to determine the effect of the variants or their genetic combinations on AH. Materials and methods: We genotyped the SCGB1D4 (IIS) gene in 167 participants (95 children with AH and 72 controls) by performing DNA sequencing in blood samples. Results: We genotyped three single nucleotide polymorphisms (SNPs). In the analysis, we found that in the presence of those SNPs and the minor alleles of individual SNPs four haplotypes were associated with an increased risk of …

Clostridium Botulinum In Honey: Prevalence And Antibiotic Susceptibility Of Isolated Strains, Ahmet Koluman, Berfi̇n Meli̇koğlu Gölcü, Okan Deri̇n, Si̇bel Özkök, Fabrizio Anniballi
Turkish Journal of Veterinary & Animal Sciences
Clostridium botulinum and rare strains of C. butyricum and C. baratii produce an extremely potent toxin, the botulinum neurotoxin (BoNT). Infant botulism is significant for both its high mortality rates and for the sophisticated treatment that it requires. Isolation and identification of C. botulinum according to standards depend on mouse bioassays to determine toxin-producing ability of strains. Polymerase chain reaction (PCR) is used to detect the types of toxins expressed by bacteria. Since honey is an important source of infant botulism, we determined the types of toxins secreted by C. botulinum strains and their antibiotic resistance. In this study, the …

Turkish Journal of Veterinary & Animal Sciences
Fasciolosis caused by Fasciola spp. (Platyhelminthes: Trematoda: Digenea) is considered the most important helminth infection of ruminants in tropical countries, causing considerable socioeconomic problems. Samples identified morphologically as Fasciola sp. in Equus caballus host species from the city of Tunis (north of Tunisia) were genetically characterized, for the first time, by sequences of the 1st (ITS-1), the 5.8S and 2nd (ITS-2) Internal Transcribed Spacers (ITS) of nuclear ribosomal DNA (rDNA). Comparison of the ITS of the Tunisian samples with sequences of Fasciola spp. from GenBank showed that the specimens examined had sequences identical to those of F. hepatica sequences selected …

Turkish Journal of Medical Sciences
The purpose of this study was comparison of the glutamate dehydrogenase (gdh) and triose phosphate isomerase (tpi) genes for detection and genetic characterization of Giardia lamblia (G. lamblia) in human stool by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP). Our assay was specific and distinguished between G. lamblia assemblages A and B. Materials and methods: Among the 325 stool samples obtained from patients with acute gastroenteritis hospitalized in the Pediatric Hospital and infected humans referred to the Tabriz Reference Laboratory (TRL), 34 Giardia-positive stool samples were identified by conventional techniques. Two assays-PCR and PCR-RFLP-targeting the tpi and …

A Maedi-Visna virus (MVV) infection was diagnosed in a 10-month-old lamb from a Turkish flock. The animal suddenly showed nervous signs and died within 2 days. At necropsy, different pulmonary and nervous lesions were observed. A Coenurus cerebralis cyst was also present in the right-brain hemisphere. Severe nonpurulent meningoencephalitis and lymphoproliferative pneumonia were detected by histopathology. MVV proviral DNA was demonstrated by polymerase chain reaction (PCR) in formalin-fixed and paraffin-embedded samples collected from the brain and the lungs. This unusual report in a young animal confirms that not only adult sheep but also lambs can develop MVV disease. The hypothesis …
