Seroprevalence of Neospora caninum in dairy cattle herds in Central Anatolia, Turkey

A total of 3287 sera collected from cows in thirty-two herds in the eight provinces of Central Anatolia of Turkey were tested for presence of Neospora caninum antibodies by using commercial ELISA kit. The overall seroprevalence of Neospora caninum was 13.96% (95% CI 13.78 to 16.22). On a provincial basis, N. caninum infection was present in all provinces while cows sampled in Kirikkale had the highest rate (P<0.05). Antibodies to N. caninum were found in 34 (23.61%) of 144 aborted cows. The prevalence of N. caninum was significantly higher in the aborted cows than in non-aborted cows (P<0.001). However, the odds ratio was 1.97, suggesting an association between abortion and seropositivity. This is the first report on serological prevalence of Neospora caninum in cows in Central Anatolia, and neosporosis in dairy cattle seems to be widespread in some provinces of this region

Segment 10 based molecular epidemiology of bluetongue virus (BTV) isolates from Turkey: 1999-2001

Bluetongue is a significant arbovirus infection that has a negative impact on ruminant productivity in Turkey. Twenty-one Turkish BTV isolates were analyzed phylogenetically, based on genome segment 10 (Seg-10) nucleotide sequences. These analyses were used to explore the epidemiological background of individual isolates from both a regional and global perspective. In the regional analysis, the different BTV strains fell into two groups (Group I and Group 2). The Turkish virus isolates were localized in Group 1 which contains two sub-groups. The neighbor-joining analysis revealed that Seg-10 of majority of the Turkish viruses was closely related to certain other virus strains allocated in the eastern lineage. The Seg-10's of two viruses (TR25 and TR26) were more closely related to strains isolated in the Asia-Australia region. These strains belong to the 'eastern' topotype identified by [Maan, S., Maan, N.S., Ross-Smith, N., Batten, C.A., Shaw, A.E., Anthony, S.J., Samuel, A.R., Darpel, K.E., Veronesi, E., Oura, C.A.L, Singh,K.P., Nomikou, K., Potgieter, A.C., Attoui, H., van Rooij, E., van Rijn, P., De Clercq, K., Vandenbussche, F., Zientara, S., Breard, E., Sailleau, C., Beer, M., Hoffman, B., Mellor, P.S., Mertens, P.P.C., 2008. Sequence analysis of bluetongue virus serotype 8 from the Netherlands 2006 and comparison to other European strains. Virology 377, 308-318]. Comparisons of amino acid sequences deduced from the Seg-10 genes showed a high level of conservation in the NS3/3A proteins from the Turkish viruses. The more frequent amino acid substitutions were identified by multiple alignment analysis, and one of the isolates (TR23) was remarkably found to be genetically quite distinct from the other isolates.

Causative pathogens and antibiotic resistance in diabetic foot infections: A prospective multi-center study

WOS: 000378759700027PubMed ID: 26965794Aim: Clinical practice guidelines for the management of diabetic foot infections developed by the Infectious Diseases Society of America (IDSA) are commonly used worldwide. The issue of whether or not these guidelines need to be adjusted for local circumstances, however, has seldom been assessed in large prospective trials. Methods: The Turk-DAY trial was a prospective, multi-center study in which infectious disease specialists from centers across Turkey were invited to participate (NCT02026830). Results: A total of 35 centers throughout Turkey enrolled patients in the trial. Overall, investigators collected a total of 522 specimens from infected diabetic foot wounds for culture from 447 individual patients. Among all isolates, 36.4% were gram-positive organisms, with Staphylococcus aureus the most common among these (11.4%). Gram-negative organisms constituted 60.2% of all the isolates, and the most commonly isolated gram-negative was Escherichia coli (15%). The sensitivity rates of the isolated species were remarkably low for several antimicrobials used in the mild infection group. Conclusions: Based on our findings, several of the antimicrobials frequently used for empirical treatment, including some also recommended in the IDSA guidelines, would not be optimal for treating diabetic foot infections in Turkey. Although the IDSA guideline recommendations may be helpful to guide empiric antimicrobial therapy of DFIs, they should be adjusted to local conditions. (C) 2016 Elsevier Inc. All rights reserved
