Bu çalışma, gebeliğin farklı dönemlerindeki fare desidua bazalis dokusunda periyodik-asit Schiff (PAS)-pozitif granüllere sahip uterus doğal katil (uNK) hücrelerinin dağılımının belirlenmesi amacıyla yapıldı. Bu amaçla, 12-14 haftalık fareler, gebe olmayan-kontrol grubu ile gebeliğin birinci, ikinci ve üçüncü haftalarının ortasına karşılık gelecek şekilde erken, orta ve geç gebelik dönemi (sırasıyla gebeliğin 3, 10. ve 17. günleri) olmak üzere 4 gruba ayrıldılar (n= 6). Plasentasyonun ilerlemesiyle birlikte metriyal bölge (MLAp; mesometrial lymphoid aggregate of pregnancy), desidua bazalis, bağlantı bölgesi ve labirint bölgesi olmak . . . üzere dört farklı bölge ayırt edildi. Desidua bazalis ve bağlantı bölgesi arasında trofoblast dev hücreleri dikkati çekti. Endometriyum dokusunda kontrol grubunda 5 adet/10.000 μm2 olarak tespit edilen PAS-pozitif uNK hücre sayısının, gebeliğin erken döneminde desidua bazalis bölgesinde arttığı dikkati çekti (26,5 adet/10.000 μm2). En yüksek uNK hücre sayısı (56 adet/10.000 μm2) gebeliğin ikinci haftasında tespit edildi. uNK hücrelerine maternal kan damarlarının içinde de rastlanırken, mesometriyal bölgedeki maternal kan damarlarının genişlediği ve tunika mediya katmanlarının belirgin bir biçimde inceldiği dikkati çekti. Gebeliğin PAS-pozitif uNK hücrelerinin sayı ve dağılımlarını etkilediği sonucuna varıldı. - Anahtar sözcükler: Fare, Gebelik, PAS, uNK = This study was carried out to determine the distribution of uterine natural killer (uNK) cells having periodic-acid Schiff (PAS) positive granules in the decidua basalis in pregnant mice. For this purpose, mice at 12-14 weeks of age were divided into four groups as non-pregnant control, and at the middle of the first, second, and the third week of the pregnancy, corresponding to early, middle, and late (3rd, 10th, and 17th days of pregnancy) gestational stages respectively (n= 6 for each group). After placentation, it was identified four different regions as metrial region (MLAp; mesometrial lymphoid aggregate of pregnancy), decidua basalis, junctional zone and labyrinth zone in mice. It was observed trophoblast giant cells between decidua basalis and junctional zone. The number of PAS-positive uNK cells was found as 5 in 10.000 μm2 in endometrium of control animals while it was determined as 26.5 number/10.000 μm2 in decidua basalis at early gestational period. The highest PAS-positive uNK cell numbers (56 number/10.000 μm2) were detected at the mid-gestational period in decidua basalis. uNK cells were also observed in the lumen of the maternal blood vessels. In mesometrial region, the dilatation of maternal blood vessels and thinning of the media layer was distinct. It was concluded that the number and the distribution of the uNK cells having periodic-acid Schiff (PAS) positive granules was affected by pregnancy. - Keywords: Mice, PAS, Pregnancy, uN More less

The aim of this study was to evaluate a simple and rapid DNA extraction method combined with a multiplex polymerase chain reaction (mPCR) for the identification of the major mastitis pathogens (Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli and Mycoplasma bovis) from milk samples. Of the 200 California Mastitis Test (CMT) positive milk samples, 45 (22.5%), 21 (10.5%) and 11 (5.5%) were detected as positive for the presence of S. aureus, S. agalactiae and E. coli by culture, respectively. In mPCR by DNA isolation method optimised here, S. aureus, S. agalactiae and E. coli were detected in 26.5% (53/200), 12% (24/20 . . .0) and 6% (12/200) of the milk samples, respectively. The abovementioned agents were observed in similar proportions when the samples were analysed by a commercial DNA isolation kit. On the other hand, M. bovis was not detected in any of the milk samples by either culture or mPCR methods. A significant difference was determined between the results of culture and mPCRs (P< 0.001). Diagnostic sensitivity and specificity of the optimised mPCR were calculated as 100% and 89.2% respectively, when culture results were considered as reference. The results suggest that the mPCR assay employed in this study could be used as an alternative routine diagnostic method for rapid, sensitive, and specific simultaneous detection of major mastitis agents in bovine milk sample More less

The discovery of antibiotics saved many lives. Infections were not as deadly a problem for clinicians as they once were. However, due to inappropriate and excessive use of antibiotics, antibiotic resistance has increased dramatically worldwide. Infectious diseases are becoming more challenging to control, and they cause increased morbidity and mortality. Also, a significant risk to human health is posed by infections associated with biofilms. To combat these drug-resistant microorganisms, several novel and alternative strategies have been identified. Bee products such as honey, bee pollen, propolis, royal jelly, bee venom, bee wax, . . .and bee bread have the potential of being used as antimicrobial or antibiofilm agents in various industrial and medical applications. Although these products have some restrictions such as their varying and complex composition, they possess significant potential in the field of medical practices as viable alternatives to antibiotics. They offer a potential solution to the issue of antibiotic resistance. The objective of this review was to offer a comprehensive analysis and evaluation of strategies based on bee products that are currently employed or have been suggested against antimicrobial resistance.

Canine hepatozoonosis is a tick-borne protozoan disease and widespread in Europe, Africa, Asia and America. There is not any available data about the presence of Hepatozoon infections in dogs in Kyrgyzstan. In the study we aimed that investigate the presence of Hepatozoon canis and the prevalance of Hepatozoon infections in dogs from Kyrgyzstan using polymerase chain reaction (PCR) and sequence analysis. To determine the prevelance of hepatozoonosis in dogs, a total of 170 blood samples were applied to PCR to amplify a fragment of 666 bp found in 185 SSU rRNA gene of Hepatozoon spp. The PCR results shown that Hepatozoon infection ra . . .te was 28.8% (49/170) in dogs. Eleven representative positive samples were sequenced to classification of the species. The nucleotide sequences were compared to the H. canis sequences which registered in GenBank using the basic local alignment search tool. Results of sequence analyse of 11 amplicons indicated that 8 were 100% identical and the other 3 sequences shared 99% similarity with H. canis. The sequences were deposited in Genbank with accession numbers from MG917709 to MG917719. It was the first record of H. canis in dogs in Kyrgyzstan More less

Although the clinical and pathological findings are important in the diagnosis of listeriosis, to isolation or to be shown the presence of the bacterium must be required for the definitive diagnosis. This study aims to investigate the availability of imprint cytological (IC) and immunocytochemical (ICC) methods in comparison with histopathological and immunohistochemical (IHC) methods for the rapid diagnosis of encephalitic listeriosis. In the study, the touching and smear preparations taken from the pons and medulla oblongata of 25 ruminants suspected with listeriosis by neurological symptoms were stained with modified giemsa and a . . .lso with ICC technic for revealing antigens, as a new method. Same tissue sections were stained with Hematoxylin&Eosin and IHC methods too, and examined under light microscope by scoring. In IC examinations, there were intensive neutrophils in 14 cases and few neutrophils in 4 cases, and no neutrophils were observed in 7 cases. In histopathological examinations, 13 of these 14 cases revealed typical microabscesses and listeria positivity in IHC staining. ICC positivity was detected in 12 (92.3%) of the listeria positive 13 cases. A highly positive correlation was observed among cytology (14), ICC (12), histopathology and IHC (13) scores (r2> 0.8; More less

In this study, it was aimed to investigate polymorphisms in seven genes (GH, PRL, STAT5A, OPN, PIT-1, LEP and FGF2) related to reproductive traits in dairy heifers. Frequency distributions of the genotypes between fertile and repeat breeder heifers groups were investigated. Allele effects on fertility were also analyzed. Blood samples were taken from a total of 160 Holstein-Friesian heifers and they were divided into two groups according to their artificial insemination numbers (AI). The heifers becoming pregnant after the first AI were used as the fertile heifers (FH, n= 80) and the heifers with 3 or more equal AIs were accepted as . . . the repeat breeder heifers (RBH, n= 80). All the animals were genotyped by the PCR-RFLP method for seven genes and the association works were performed for 145 animals (RBH, n= 79; FH n= 66). For all loci investigated, two alleles and three genotypes were found for overall population with the exception that PRL locus had two alleles and two genotypes. The chi-square test (.2) revealed that the whole population and the two groups separately were at Hardy-Weinberg equilibrium. The genotype distributions of PIT-1 and STAT5A conspicuously differed between the FH and the RBH groups; however, these differences were not found significant. Association of GH-AB genotype was found significant on AI number for the first pregnancy. Mixed effect logistic regression model was used to investigate the allele effects on fertility. No linkage disequilibrium was detected between the investigated loci More less
