Background: The main objective of this study is to review publications on the presence of Demodex spp. in patients diagnosed with blepharitis worldwide and to analyse the trends and groups in this field. Methods: This bibliometric study was conducted to detect the presence of Demodex spp. in patients diagnosed with blepharitis worldwide between 1984 and 2023. For this purpose, 288 studies were examined as a result of searches using the keywords "Blepharitis and Demodex" in Web of Science (WOS) databases. All text data was analysed using VOSviewer software to ensure accuracy and reliability. In this study, analysis using text mining and data visualization techniques (bubble maps and graphs) helped to make the results more understandable. Results: This study provided information on 288 articles from WOS databases. The average total number of citations is 1305 and the H-index is 41. The majority of articles (63%) were published in the field of ophthalmology. The countries that published the most articles on this topic were the USA (24%), China (13%), and Turkey (11%). Conclusion: This study is the first bibliometric study of patients diagnosed with blepharitis due to Demodex spp. The most used keyword in blepharitis is Demodex. The most studied field of research is ophthalmology and the most studied country is the United States of America. The results of this bibliometric analysis conducted by us reveal global trends in the presence of Demodex spp. in patients diagnosed with blepharitis and provide important information for future directions of research.

Background: We aimed to determine the common Echinococcus granulosus genotypes in Ağrı, Türkiye and to obtain information on the transmission of this parasite. Methods: Cystic echinococcosis samples from 100 slaughtered cattle and 100 slaughtered sheep and faecal samples from 200 stray dogs were included in 2021. Collected cyst fluid samples and faces were examined microscopically. DNA was isolated from the germinal membrane of the cysts and from the parasite eggs in the stool samples. The mitochondrial cytb gene region of the parasite was amplified by PCR. Genotypes were determined using the Basic Local Alignment Search Tool (BLAST) after sequence analysis of PCR amplicons. Results: The highest percentage of cysts was found in the lungs of sheep and the liver of cattle. In addition, 75% of sheep cysts and 25.6% of cattle cysts were fertile. Taenia spp./Echinococcus spp. eggs were found in 6% of the faeces of 200 dogs examined microscopically. E. granulosus eggs were detected in 4 out of 50 stool samples analysed by PCR. All samples analysed by sequence analysis were identified as E. granulosus s.s. G1 genotype. Sequence comparison revealed revealed one or more-point mutations in different regions of the five samples. Conclusion: E. granulosus s.s. G1 genotype, known as sheep strain, is common in the Ağrı, Türkiye. The controlled slaughter of livestock, especially sheep, and the avoidance of feeding hydatid cyst organs to dogs, together with public education, were necessary to prevent the spread of the disease.
