Abstract
This study analyzed the molecular and phylogenetic profiles of Theileria annulata, the causative agent of tropical theileriosis in cattle, and its tick vector Hyalomma scupense in Algeria. Forty H. scupense ticks were collected in Medea, with 5 testing positive for Theileria spp. based on partial COXIII gene sequences. Positive ticks were further analyzed using COX1 and 12S rRNA genes. Two novel H. scupense 12S rRNA haplotypes and one novel COX1 haplotype were identified. One T. annulata haplotype previously reported in Algerian cattle was detected. This represents the first molecular characterization of T. annulata from H. scupense ticks in Algeria, providing insights into the genetic diversity of the parasite vector in this region. Overall, the study reveals new haplotypes for both the tick vector and parasite, furthering our understanding of their molecular profiles and phylogenetics in Algeria.
期刊介绍:
Comparative Immunology, Microbiology & Infectious Diseases aims to respond to the concept of "One Medicine" and to provide a venue for scientific exchange. Based on the concept of "Comparative Medicine" interdisciplinary cooperation between specialists in human and animal medicine is of mutual interest and benefit. Therefore, there is need to combine the respective interest of physicians, veterinarians and other health professionals for comparative studies relevant to either human or animal medicine .
The journal is open to subjects of common interest related to the immunology, immunopathology, microbiology, parasitology and epidemiology of human and animal infectious diseases, especially zoonotic infections, and animal models of human infectious diseases. The role of environmental factors in disease emergence is emphasized. CIMID is mainly focusing on applied veterinary and human medicine rather than on fundamental experimental research.
