Publication Evaluation of serum indirect haemagglutination test results of suspected cystic echinococcosis cases from 2009-2017(Pakistan Medical Assoc, 2022-06-01) Tuzemen, Nazmiye Ulku; Alver, Oktay; Ozakin, Cuneyt; Ener, Beyza; Tuzemen, Nazmiye Ulku; TÜZEMEN, NAZMİYE ÜLKÜ; Alver, Oktay; ALVER, OKTAY; Ozakin, Cuneyt; ÖZAKIN, CÜNEYT; Ener, Beyza; ENER, BEYZA; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Mikrobiyoloji Anabilim Dalı.; A-4290-2018Objective: This study aims to evaluate the serological, radiological and epidemiological analysis of suspected cystic echinococcosis patients, and to assess the positivity rate in the region. Method: The retrospective study was conducted at Bursa Uludag University Hospital, Turkey and comprised data from January 2009 to December 2017 related to patients of either gender with suspected cystic echinococcosis who underwent indirect haemagglutination testing. Demographic and clinical data of patients who tested positive were analysed. Statistical analysis was done using SPSS 23. Results: Of the 3910 patients with a mean age of 41.6 +/- 19.35 years (range: 0-93 years) who underwent indirect haemagglutination testing, 692(17.7%) tested positive; 390(56.4%) females, and 302(43.6%) males. The highest seropositivity rate 107(15.5%) was observed in 2011, followed by 104(15%) in 2016. Seropositive cases were predominantly seen in those aged 40-49 years 131 (18.9%), followed by those aged 50-59 years 124 (17.9%). Conclusion: Cystic echinococcosis was found to be a public health problem in South Marmara region of Turkey.Publication Acanthamoeba keratitis and acanthamoeba conjunctivitis: A case report(Iranian Scientific Society Medical Entomology, 2020-04-01) Alver, Oktay; Baykara, Mehmet; Yuruk, Merve; Ülkü Tüzemen, Nazmiye; ALVER, OKTAY; BAYKARA, MEHMET; TÜZEMEN, NAZMİYE ÜLKÜ; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Mikrobiyoloji Anabilim Dalı; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı; 0000-0002-5555-1649; AAA-5241-2021; ABI-7051-2020; CGE-2103-2022Acanthamoeba species are vision-threatening agents by causing cornea infections known as Acanthamoeba keratitis. A 5 year-old kid with the complaints of erythema, eyelid edema, inflammation, limitation of eye movements in the right eye, and having no history of wearing contact lenses or trauma, was diagnosed of Acanthamoeba conjunctivitis through laboratory examinations in the Ophthalmology clinic. The visual sharpness of the patient improved after the treatment. A 44 year-old female patient suffering from pain, stinging, irritation, and inability to see in the left eye with the history of wearing contact lenses or trauma was diagnosed of Acanthamoeba keratitis through laboratory examinations. The agent was isolated and identified as "A. castellam" in the Genotype "T2". Examination of the left eye on the 15th day of treatment indicated that all complaints disappeared except for the cataract originated visual loss. However, the first diagnosis of Acanthamoeba keratitis appeared in the literature on a case with no history of wearing contact lenses and trauma it is found to be attention grabbing. We think that Acanthamoeba should not be ignored among microbial agents that cause eye infection with or without trauma and contact lens usage history.Publication Determination of diagnostic value of cELISA for the diagnosis of anaplasmosis in clinically suspected ruminants(Kafkas Üniversitesi, 2015-09-01) Selçuk, Özgür; Alver, Oktay; Çatık, Serkan; Aydın, Levent; Şenlik, Bayram; Selçuk, Özgür; ALVER, OKTAY; Çatık, Serkan; AYDIN, LEVENT; ŞENLİK, BAYRAM; Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Mikrobiyoloji Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.; 0000-0003-2964-2245; AAA-5241-2021; JLA-7878-2023; JLJ-9087-2023; HLG-4450-2023; GBN-0139-2022The aim of this study was to determine diagnostic value of cELISA in anaplasmosis in clinically suspected animals and to compare the cELISA results with the clinical examination results. For this purpose a total of 720 ruminants (457 cattle, 146 sheep, 117 goat) were examined in terms of clinical signs. Eighty-eight ruminants consisting of 61 cattle, 11 sheep and 16 goat which had the symptoms of anemia, fever, icterus, weakness, depression and lack of appetite were selected for the study. Blood samples were collected from the jugular vein of all clinically suspected animals and serum samples were separated. A commercially available competitive enzyme-linked immunosorbent assay (C-ELISA) kit was used for determine antibodies to Anaplasma species. cELISA based diagnosis revealed that 47 of 88 serum samples (53.4%) were positive for anaplasmosis. In serological examination Anaplasma specific antibodies were determined in 45.9% of cattle, 63.6% of sheep and 56.2% of goats. Seropositivity rate was statistically differ among the age groups of cattle and the highest seropositvity rate was found in <12 month age (P < 0.005). However no difference was found in the seropositivity rate of Anaplasma in sheep and goat in relation to age group. From the data obtained in this study it can be concluded that clinical findings are not sufficient criteria for the diagnosis of anaplasmosis and must be supported by serological examination.
