ABSTRACT
Objective: Cystic echinococcosis (CE) is prevalent, especially in animals in Turkey and stands as a significant zoonose. In this study, we aimed to retrospectively evaluate the indirect hemagglutination (IHA) tests results performed on samples of CE suspected patients in microbiology laboratory of our hospital. Methods: One thousand six hundred-seven files of patients admitted to hospital between January 2013 and December 2020 were examined for the presence of anti-E. granulosus immunoglobulin G antibodies. The patient's socio-demographic characteristics and radiological data were obtained from the hospital automatization system. Results: A total of 1.607 file records; 644 (40.1%) males and 963 (59.9%) females, aged between 1-96 years (average 45.26±19.91) were examined. It was found that 244 (15.18%) of the patients were positive, 78 (4.86%) were determined at an intermediary value and 1.285 (79.96%) were negative. According to the IHA method a titer of 1/320 and above were evaluated as positive. Compared to anti-E. granulosus IgG antibody titers 164 radiological data; while 28.6% of 21 patients who are evaluated as negative (1/80) and 46.2% of 78 patients who were evaluated as intermediary titer (1/160) had cystic lesion in the radiological findings. Conclusion: Based on the data, it is suggested that while interpreting the patient's serum antibody titers, patient's clinical and radiological findings should also be taken into account. If possible, it should be used along with another serological method like ELISA to assist CE patient's diagnosis and treatment.

Background: In this study, it was aimed to investigate Mycobacterium bovis strains isolated from lungs and lymph nodes of slaughtered animals on clonal level by using different methods such as spoligotyping, enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR), randomly amplified polymorphic DNAs (RAPD-PCR) and OUT-PCR. Comparative evaluation of these methods was further conducted. Methods: A total of 38 M. bovis isolates were evaluated in the study. DNA isolation of all M. bovis strains isolated from pruvat free Löwenstein Jensen medium was done by boiling method for ERIC-PCR, RAPD-PCR, and OUT PCR. Mickle device was used for DNA isolation for spoligotyping method. Results: In 38 M. bovis isolates examined in our study, 4 different groups were determined by spoligotyping and RAPD-PCR test methods, and 5 different groups were detected in ERIC-PCR tests. In the OUT-PCR tests, the band which provides sufficient type separation was not observed. Conclusion: ERIC-PCR, RAPD-PCR, and OUT-PCR methods are easily applicable, simple, and relatively inexpensive methods for evaluating the differences between origins in the typing of M. bovis. The tests need to be evaluated in more detail with extensive studies.
