Feline Herpesvirus Type-1 (FeHV-1) ınfection in shelter cats with and without respiratory disorders

Bu çalışmada, sokak kedilerinin toplandığı bir barınaktaki sağlıklı görünüşlü (asemptomatik, n:54) ve solunum sistemi ve/veya konjunktivitis bulgularına sahip (semptomatik, n:21) kedilerden örneklenen nazal ve konjunktival sürüntülerde polimeraz zincir reaksiyonu (PCR) tekniği ile Feline Herpesvirus tip 1 (FeHV-1) prevalansı araştırıldı. Bu amaç- la, 75 adet nazal ve 74 adet konjunktival sürüntü olmak üzere toplam 149 adet örnek toplandı. Örneklenen kedilerin % 25.3'ünde (19/75) FeHV-1 DNA'sı saptandı. Semptomatik kedilerin %47.6'sında (10/21) ve sağlıklı görünüşlü kedilerin %16.7'sinde (9/54) FeHV-1 enfeksiyonu saptandı. Sağlıklı görünüşlü ve klinik bulgulu kedilerde iki yaş grubu (>6 ay ve <6 ay yaşlı) arasındaki enfeksiyon oranları yönünden farklılıklar istatistiksel olarak değerlendirildiğinde, sağlıklı görü- nüşlü grupta farklılığın önemli olduğu belirlendi (P?0.05). Sonuç olarak, FeHV-1'in barınak kedilerinde yüksek prevalansa sahip olduğu tespit edildi.In this study, the prevalence of Feline Herpesvirus type 1 (FeHV-1) was investigated in nasal and conjunctival swabs sampled from the shelter cats that were healthy (asymptomatic n:54) but having respiratory disorder and/or conjunctivitis (symptomatic n:21) housed in an animal shelter using polymerase chain reaction (PCR) technique. Totally, 149 swab samples including 75 nasal and 74 conjunctival swabs were collected. The FeHV-1 DNA was positive in 25.3% (19/75) of all cats sampled. The presence of FeHV-1 infection was determined in 47.6% (10/21) of symptomatic and in 16.7% (9/54) of clinically healthy cats. Moreover, the differences in FeHV-1 infection rates were statistically significant between two age groups (&gt;6 months and &lt;6 months) in clinically healthy appeared cats (P&lt;0.05). In conclusion, FeHV-1 was found prevalent in the shelter cats

Synthesis and molecular docking studies of some novel antimicrobial benzamides

YALCIN, Gozde/0000-0002-9689-2239; yildiz, ilkay/0000-0001-9526-0232; Acar, Cemre/0000-0001-8965-3267WOS: 000505596300026PubMed: 31699395Common use of classical antibiotics has caused to the growing emergence of many resistant strains of pathogenic bacteria. Therefore, we aimed to synthesize a number of N-(2-hydroxy-(4 or 5)-nitrophenyl)benzamide derivatives as a new class of antimicrobial compounds. Moreover, our second goal is to predict the interaction between active structures and enzymes (DNA-gyrase and FtsA) in the binding mode. in this study, thirteen N-(2-hydroxy-(4 or 5-nitrophenyl)-substituted-benzamides were synthesized and determined for their antimicrobial activity using the microdilution method. According to this work, none of the compounds showed any activity against Candida albicans and its clinical isolate. Some of the benzamides (4N1, 5N1, 5N2) displayed very significant activity against Staphylococcus aureus and MSSA with < 4 mu g/ml MIC value, even they were found to be more potent than ceftazidime. 4N1 was also found to be more effective than gentamicin against Enterococcus faecalis clinical isolate. Molecular docking studies revealed that 4N1, 5N1, and 5N2 showed a good interactions with DNA-gyrase. Moreover, 5N1 has interacted with FtsA enzyme in the binding mode, as well. Only compound 5N4 displayed very good activity against Escherichia coli ATCC 25922. These findings showed us that 4N1, 5N1, 5N2, and 5N4 could be lead compounds to discover new antibacterial candidates against multidrug-resistant strains

Clinical and molecular evaluation of MEFV gene variants in the Turkish population: a study by the National Genetics Consortium

Familial Mediterranean fever (FMF) is a monogenic autoinflammatory disorder with recurrent fever, abdominal pain, serositis, articular manifestations, erysipelas-like erythema, and renal complications as its main features. Caused by the mutations in the MEditerranean FeVer (MEFV) gene, it mainly affects people of Mediterranean descent with a higher incidence in the Turkish, Jewish, Arabic, and Armenian populations. As our understanding of FMF improves, it becomes clearer that we are facing with a more complex picture of FMF with respect to its pathogenesis, penetrance, variant type (gain-of-function vs. loss-of-function), and inheritance. In this study, MEFV gene analysis results and clinical findings of 27,504 patients from 35 universities and institutions in Turkey and Northern Cyprus are combined in an effort to provide a better insight into the genotype-phenotype correlation and how a specific variant contributes to certain clinical findings in FMF patients. Our results may help better understand this complex disease and how the genotype may sometimes contribute to phenotype. Unlike many studies in the literature, our study investigated a broader symptomatic spectrum and the relationship between the genotype and phenotype data. In this sense, we aimed to guide all clinicians and academicians who work in this field to better establish a comprehensive data set for the patients. One of the biggest messages of our study is that lack of uniformity in some clinical and demographic data of participants may become an obstacle in approaching FMF patients and understanding this complex disease
