This survey was conducted to determine prevalence of Toxocara spp. ova in public parks in Erzurum, Turkey. A total of 214 soil samples were collected from July 2007 to June 2008 in 36 public parks, of which 28 were unfenced and 8 were fenced. Prevalence of Toxocara spp. was 64.28% in unfenced public parks, while no contamination was observed fenced public parks (p<0.001). Average number of Toxocara spp. ova was 1.43 per 50 g sand ranging from 1 to 7. Moreover, soils from unfenced public parks were contaminated with Taeniid spp. ova (3.12%). In conclusion, public parks and/or playgrounds should be fenced to prevent fecal contamination, suggesting that a more frequent surveillance should be performed and preventive measures should be taken and enforced by local governments to reduce likelihood of zoonoses in children.

This survey was conducted to determine prevalence of Toxocara spp. eggs and seasonal variation of this prevalence in public parks in Ankara, Turkey. A total of 259 sand samples were collected from May 2005 to April 2006 in 40 public parks for determining prevalence. To attain seasonal variation, a total of 696 sand samples were collected from five public parks regularly throughout year. Prevalence of Toxocara spp. and combination of Toxascaris leonina and Taenia spp. was 15.05% and 0.38%. Overall, 45% of public parks were contaminated. There was a seasonal variation in prevalence. Prevalence of Toxocara spp., Toxascaris leonina, and Taenia spp. eggs during summer (4.21%) was lower than during spring (12.64%), autumn (13.21%), and winter (9.77%; p < 0.05). Average number of Toxocara spp. eggs was 2.57 per 50 g of sand, with average dimension of 70.1 mum. In conclusion, prevalence data are consistent with international data reported in other metropolitans. Our results indicate that the public parks in surveyed areas may be a source of toxocariasis. Effective preventive measures should be established.

This study was conducted to determine the control of helminth egg contamination of raw vegetables by washing. A total of 199 unwashed and 199 washed lettuce, parsley, carrots, dill, rocket, and green-peppers, provided by a catering service in Bursa, Turkey, between March and June 2009, were subjected to helminth egg count under light microscopy. Helminth eggs were detected in six (3.0%) unwashed samples and not in any washed samples (p<0.01). Ascaris lumbricoides and Toxocara spp. were detected in four (2.0%) and two (1.0%) unwashed vegetables, respectively, mostly among leafy vegetables such as lettuce and parsley. Our data confirm that washing procedures before consumption of raw vegetables regardless of the providers' sanitation should be performed to avoid transmission of helminths.

Equine piroplasmosis (EP) is a hemoprotozoan tick-borne disease with worldwide distribution that is caused by Theileria equi and Babesia caballi. There are studies reporting the presence of equine piroplasmosis in Turkey but the situation in Erzurum is unknown. The aim of the current study was to determine the situation of equine piroplasmosis in jeered horses in Erzurum. Between April and August 2015, a total of 125 Arabian horse were examined and blood samples were collected. At the time of sampling, animals were also examined for tick infestations and clinical signs. Besides microscopic examination of Giemsastained blood smears, multiplex PCR performed with species specific primers partially amplifying the 18S rRNA gene of B. caballi and T. equi. During the microscopic examination of blood smears, T. equi piroplasms were found in 6 (4.8%) samples. In total, 11 (8.8%) T. equi DNA were detected with multiplex PCR. B. caballi piroplasms or DNA were not obtained. BLAST analysis of the sequenced T. equi samples (GenBank: KU921661-KU921667) indicated 98.8-100% identity to each other, and 100% similarity to T. equi isolates in South Africa, Iran, China, Sudan, India, Mongolia, Trinidad, Kenya, Spain, Serbia, Bosnia and Herzegovina and Turkey (Bursa). The results of our study indicate that T. equi occurs more frequently than B. caballi in the study area. To the authors' knowledge, this is the first report of the molecular detection of equine piroplasmosis in jeered horses in Erzurum, Turkey.
