The novel group of Borrelia was initially isolated from Hyalomma aegyptium ticks in Turkey and it was recently found in blood and multiple organs of tortoises exported from Jordan to Japan. However, the ecology of these spirochetes and their development in ticks or the vertebrate hosts were not investigated in detail; our aims were to isolate the pathogen and to evaluate the possibility of transstadial transmission of Borrelia turcica by H. aegyptium ticks. Ticks were collected from Testudo graeca tortoises during the summer of 2013 from southeastern Romania. Engorged nymphs were successfully molted to the adult stage. Alive B. turcica was isolated from molted ticks by using Barbour-Stoenner-Kelly (BSK) II medium. Four pure cultures of spirochetes were obtained and analyzed by PCR and sequencing. Sequence analysis of glpQ, gyrB and flaB re...

Thus, intestinal infective larvae are first exposed to the immune system of the host, and antigens from the worms may be the earliest marker in the diagnosis of trichinellosis and may contribute to vaccine development to prevent Trichinella infections in pigs.MethodsA cDNA library of intestinal infective larvae of T. spiralis at 6 hours post infection (p.i.) was constructed and immunoscreened using serum collected from pigs that were infected with T. spiralis at 26 days p.i. T. spiralis cystatin-like protein (Ts-CLP) gene encoding a 45.9 kDa protein was cloned and expressed in Escherichia coli. The rabbit antisera were generated and used to determine the location of Ts-CLP in the parasite. Transcription levels of Ts-CLP in different developmental stages of T. spiralis were...

Taking into consideration the big enough number of the slaughtered buffaloes and the evolution of some important parasitosis at this species, some of them being zoonosis, we consider very important the research regarding the incidence of endoparasitosis at this species and their correlation with different determinating factors. For this, were examinated 134 buffaloes providing from 3 dictricts from Central
