    3D Printing in Veterinary Medicine
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Huri, Pınar Yılgör; Veteriner; Veteriner Fakültesi
    The use of 3D printing technology in the field of medicine, which started with the millennium, continues to increase today. Depending on the technological developments in this field, the use of rapid prototyping technology in the field of veterinary medicine is becoming widespread with the development of 3D printers, increasing material variety, cheaper printing costs and being more accessible. Additive manufacturing is used in veterinary education and training, experimental research and clinical studies, and its area of use is expanding day by day. In this review, both the current usage potential will be evaluated and the expected developments in the near future will be revealed.

    Lenfomalı Bir Kedide Pulmoner Veno-Oklüzif Hastalık
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Tenekeci, Gözde Yücel; Veteriner; Veteriner Fakültesi
    Pulmoner Veno-Oklüzif Hastalık (PVOH) pulmoner hipertansiyonun neden olduğu, insanlarda ve hayvanlarda nadir görülen bir hastalıktır. Bu olgu ile bir kedide gözlenen Pulmoner Veno-Oklüzif Hastalık’ın patomorfolojik yönden incelenmesi amaçlanmıştır. 11 yaşlı erkek kedinin ekokardiyografisinde sağ atriumda kitle gözlendi. Tedavilerin ardından solunum güçlüğüne bağlı ölen kedinin nekropsisi yapıldı. Makroskobik olarak, mezenteriyal ve mediastinal lenf yumrularında ve kalpte kitleler ile karşılaşıldı. Akciğer muayenesinde ödem ve konjesyon ile konsolide alanlar görüldü. Histopatolojik olarak bağırsak, lenf yumruları ve kalpte neoplastik lenfoid hücreler gözlendi. Akciğerde şiddetli intimal fibrozise bağlı venlerin lümenlerinde daralma ve tıkanmalar dikkati çekti. Etkilenen çoğu damarların çevresinde kapillarizasyon gözlendi. Masson trikrom boyamasıyla intimal fibrozis tespit edilirken, tıkalı damarlar Verhoeff-van Gieson boyamasıyla gösterildi. Yapılan klinikopatolojik incelemeler sonrasında PVOD ve kardiyak metastazlı intestinal lenfoma tanıları konuldu. Bu olguda bir kedide Pulmoner Veno-Oklüzif Hastalık patomorfolojik yönden değerlendirilmiş ve PVOD ile lenfoma ile ilişkisi tartışılmıştır. Klinikopatolojik incelemeler sonucunda erkek bir kedide PVOH, intestinal lenfoma ve kardiyak metastazı tanımlanmıştır.

    Prevalence and rapid identification of Salmonella Infantis in broiler production in Turkey
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Sareyyüpoğlu, Barış; Veteriner; Veteriner Fakültesi
    In the present study, the prevalence of Salmonella enterica subsp. enterica serovar Infantis (S. Infantis) and other serovars were investigated in samples collected from commercial broiler chicken flocks in Turkey according to the ISO 6579:2002/Amd 1:2007, Annex D, standard method. Furthermore, previously developed S. Infantis-specific polymerase chain reaction (PCR)-based methods with primers targeting fljB, fliC, IMP1-IMP2-IMP3 and sinI were conducted in different media (BPW, MRSV, MKTTN, XLD, and XLT4 agars) and during four incubation stages (6, 12, 18, and 24 h) of the ISO 6579 procedure to develop rapid and reliable diagnosis method. One-hundred thirty-three (15.6%) Salmonella strains were isolated from a total of 848 samples (240 cecal swabs, 200 cloacal swabs, 190 intestinal contents, 59 feed, 39 dust, and 120 litter). The serovar distribution of isolated strains was as follows: S. Infantis, 88.70%; S. Agona, 2.3%; S. Kentucky 1.50, S. Hadar 1.50, and S. Tennessee 1.50; S. Mbandaka 0.75 %, S. Montevideo 0.75 %, S. Enteritidis 0.75 %, S. Adelaide 0.75 %, S. Liverpool 0.75 %, and S. Derby 0.75 %. Primers targeting fljB, fliC, and IMP1-IMP2-IMP3 were not able to detect all S. Infantis isolates, therefore, a novel PCR technique was developed and validated in the study. It was concluded that it is a fast, reproducible and low-cost alternative to the gold standard method by detecting the S. Infantis isolates on the 3rd day at the earliest by PCR (sinI PCR). using primers specific to S. Infantis species.

    Some inherited disorders in pacing horses in Turkey
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Özbeyaz, Ceyhan; Veteriner; Veteriner Fakültesi
    This study was carried out to detect the presence of mutant alleles of polysaccharide storage myopathy (PSSM) and severe combined immunodeficiency (SCID) disorders in pacing horses raised in different regions of Turkey. Blood/hair samples from 264 (182 Indigenous, 31 Iranian, 24 Afghan, and 27 Bulgarian) pacing horses aged 4 and over were used. As a result of the study, a mutation-heterozygosis (GA) in the GYS1 gene related to PSSM disease was detected in one of the pacing horses (Bulgarian horse). No deletions were observed in the DNA-PKcs gene region in the pacing horses for SCID disease. This study has been carried out to identify the status of two inherited disorders in pacing horses in Turkey. It was determined that there are no mutant genes in indigenous pacing horses, in terms of PSSM and SCID disorders, which are the major hereditary disorders in horses.
