First Investigation on Vectorial Potential of Blattella Germanica in Turkey
(Chartered Inst. of Building Services Engineers, 2017) Oğuz, B.; Özdal, N.; Orunç Kilinç, Ö.; Değer, M.S.
Cockroaches are claimed to be mechanical vectors of microorganisms such as intestinal parasites, bacteria, fungi, and viruses. This study was conducted to determine the potential role of cockroaches as carriers of parasites having medical importance in Van province, Turkey. One hundred and thirty-eight cockroaches were collected from different parts of apartments and houses between March and April 2014. All of the collected cockroaches were identified as Blatella germanica. They were examined for isolation and identification of intestinal parasites from external surface. The results showed that 66 (48%) of the cockroaches harbored parasitic organisms. Of these, 96.6% were protozoon and the remaining 3.4% were helminthes. Isolated helminth, species were Toxocara sp. (3%), Ascaris lumbricoides (3%), Trichostrongylus sp. (1.5%), Trichuris trichiura (1.5%) and unidentified nematode egg samples (3%). The protozoon identified during the study were Endolimax nana (7.6%), Blastocystis hominis (41%), Entamoeba histolytica/E. dispar (16.7%), unsporulated coccidial oocyst (7.6%), Chilomastix mesnilli (4.5%), Entamoeba coli (35%), Giardia sp. (13.6%) and Iodamoeba butschlii (7.6%). In conclusion, Blattella germanica was found to harbor intestinal parasites of public health importance. Hence, awareness on the potential role of cockroaches in the mechanical transmission of intestinal parasites needs to be further investigated. Control of cockroaches will substantially minimize the spread of diseases caused by helminths and protozoons in our environment. © 2017, Chartered Inst. of Building Services Engineers.

Molecular Investigation and Genotyping of Theileria Equi and Babesia Caballi in Horses in Mus Province, Turkey
(Hellenic Veterinary Medical Society, 2020) Oguz, B.; Özdal, N.; Deger, M.S.; Bicek, K.
Equine Piroplasmosis (EP) is a tick-borne disease caused by Theileria equi and Babesia caballi of the phylum Apicomplexa. In this study, 102 blood samples were randomly collected from the horses in Mus province of Turkey. PCR analysis, gene sequences, and phylogenetic analyses were carried out for detecting the presence and genotypic characteristics of species that cause piroplasmosis. Four (3.9%) of the 102 horses that were examined were found to be positive for T. equi, while B. caballi was not detected. Theileria equi isolates that were detected in the sequence analyses were found to be 100% identical to the isolates that were isolated from the horses in Turkey, the United States, and South Africa as well. In the phylogenetic analysis, all of the isolates were found to cluster with T. equi sequences in the genotype A. This study, in which we revealed intraspecies sequence heterogeneity of the parasite using the 18S rRNA gene region, provides important epidemiological data for equine piroplasmosis. However, we think that determining the characterization of genotypes that are common in different parts of our country is extremely important in terms of developing new diagnostic tools and vaccines. © 2020.

Prevalence of Elisa-Detected Specific Antibodies Against Besnoitia Besnoiti in Cattle of the Eastern and Southeastern Anatolian Regions, Turkey
(Shiraz University, 2019) Özdal, N.; Oğuz, B.; Orunç Kılınç, Ö.; Karakuş, A.; Değer, S.
Background: Besnoitiosis caused by Besnoitia besnoiti is regarded as a re-emerging disease in cattle because of the increased number of cases and geographical distribution in many European countries. Aims: The present study was conducted to determine the presence of B. besnoiti in cattle in the Eastern and Southeastern Anatolia of Turkey. Methods: Blood samples were collected from 450 cattle in the provinces of Mus, Van, Siirt, and Diyarbakir. PrioCHECK®Besnoitia Ab 2.0 enzyme-linked immunosorbent assay (ELISA) kit was used to detect specific anti-B. besnoiti antibodies in the serum samples. Results: Twelve (2.7%) of the 450 asymptomatic cattle were seropositive against B. besnoiti. In cattle, the prevalence rates were 0%, 3.7%, 3.4%, and 1.1% in Mus, Siirt, Diyarbakir, and Van provinces (P>0.05), respectively. This study is the first to investigate the presence of B. besnoiti in cattle raised in the Eastern and Southeastern Anatolia of Turkey. Conclusion: Although the ELISA test revealed some positive cases, concrete evidence for the establishment of clinical B. besnoiti infection could not be verified. More comprehensive analysis would be necessary to determine the significance of the present observations. © 2019 Shiraz University. All rights reserved.
