We described the aetiological agents of outbreaks of bovine ephemeral fever (BEF) that occurred in 1985 and 2012 in Turkey, and identify mutations in the viruses from both outbreaks. Outbreaks have emerged periodically every 4-5 years in the same regions in Turkey. Because these regions are located in a subtropical climatic zone, good conditions for vector populations exist. The results of this study show that the BEFVs from outbreaks in Turkey vary significantly. Effective prevention will require a vaccine that contains BEFVs from different genetic clusters.
Pseudocowpox virus (PCPV) infects cattle throughout the world and has zoonotic potential. However, it is not known to infect cattle in Turkey. In August 2013, we observed ulcerative nodular swelling and pustules on udder and teats of a cow in a small village nearly Lake of Bafa, Milas, Mugla locate in southwestern part of Turkey. Interestingly, the similar lesions were also observed on skin of milkier women's hand at the same time. A PCPV strain was characterized based on the major envelop gene sequence. The phylogenetic analysis showed that the isolated strain was closely related to the members of other parapoxvirus genus. This study provides the first description of PCPV infection in Turkey.
Human adenoviruses (HAdVs) are responsible for various clinical diseases. Molecular epidemiological studies of respiratory HAdVs are limited in Turkey. To determine the main genotypes and epidemiological characteristics of HAdVs in patients with respiratory symptoms. HAdV PCR-positive extracts of nasal/nasopharyngeal specimens sent to the Turkish Public Health Institution from various cities of Turkey in 2015-2016 were investigated by seminested PCR. Partial sequence analysis of the hexon gene of HAdVs was performed. SPSSv.24.0 was used. A total of 23/68 (33.82%) HAdV-positive samples were amplified. Mastadenovirus B, C, D, and F were detected and mastadenovirus B (10/23; 43.5%) and C (10/23; 43.5%) were predominant strains. Interestingly, HAdV-F known to have gastrointestinal system tropism was detected in two patients with respiratory symptoms. HAdV-B3 was the most prevalent genotype (9/23; 39.1%). Also, HAdV-B7 is defined as a reemerging pathogen. It is noteworthy that there is a cluster of four HAdV-C strains showing a close paraphyletic relationship with HAdV-2/6 intertypic recombination. To our knowledge, this is the first study showing that HAdV-B7 reemerging pathogen circulating in patients with respiratory infections in our country. It is also necessary to emphasize that HAdV-2/6 recombinant strains were detected in this study for the first time in Turkey.
Abortion outbreaks associated with congenital malformations in two distinct small-ruminant flocks were reported in Turkey in 2013-2014. This paper describes the first molecular characterization of Turkish Akabane virus strains in small-ruminant flocks using partial sequence analysis of the S segment and pathological findings.
Previous studies demonstrated elevated plasma leptin and angiotensinogen (PRA) levels in essential hypertension. However, a few studies investigated the relationship between leptin and angiotensinogen levels in both lean and overweight/ obese hypertensives. The aim of the present study was therefore to examine the relationship between blood pressure, leptin and plasma renin activity in normotensives and in both lean and overweight/obese patients with essential hypertension. Two groups of subjects who were carefully matched for age, gender, waist:hip ratio and body mass index (BMI) were studied: 28 normotensives (NT) (age: 40.1 years old, BMI: 28.1 male/female: 18/10) and 33 newly diagnosed mild to moderate essential hypertensives (EHT) (age: 38.9± 10 years old, BMI: 27.9±4.8kg/rn2, male/female: 22/11). No significant differences in age, gender, waist:hip ratio, fasting blood glucose and BMI were detected between EHT and NT groups. However, systolic and diastolic pressures, mean arterial blood pressures, plasma leptin levels and PRA were significantly higher in EHT group than in NT group (P = 0.001). Plasma leptin levels were strongly correlated with BMI in EHT (r=0.67, P=0.001) and NT groups (r=0.44, P=0.001). Plasma leptin levels were correlated with plasma PRA levels in both EHT and NT groups (r = 0.66 and r = 0.44; both P <0.05, respectively). There was no correlation between leptin or PRA and systolic, diastolic pressures, or mean arterial blood pressures. Furthermore, the patients were divided as lean (n = 16) and overweight/obese (n = 17) and compared with BMI-matched controls. In both subgroups, plasma leptin and PRA levels were also higher than those of controls. Our results showed that elevated plasma leptin and PRA are associated with hypertension in both lean and overweight/obese hypertensives. Moreover, plasma leptin was significantly correlated with plasma angiotensinogen levels. These findings suggest that adipose mass is an important determinant of blood pressure, although the mechanism is not clear.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
