| molecular epidemiological survey on the vectors of thelazia gulosa, thelazia rhodesi and thelazia skrjabini (spirurida: thelaziidae). | a polymerase chain reaction (pcr)- based assay developed for the specific identification of thelazia gulosa, thelazia rhodesi and thelazia skrjabini (nematoda, spirurida), which cause bovine ocular thelaziosis, was evaluated for its usefulness in detecting the intermediate hosts and in estimating the infection prevalence of vectors in field conditions throughout 5 years (from 1997 to 2001). a total of 5190 flies were captured and identified as musca larvipara, musca osiris, musca autumnalis, mus ... | 2003 | 14636023 |
| [ecology of thelazia spp. in cattle and their vectors in italy]. | the genus thelazia (spirurida, thelaziidae) includes a cosmopolitan group of eyeworm spirurids responsible for ocular infections in domestic and wild animals and transmitted by different species of muscids. bovine thelaziosis is caused by thelazia rhodesi desmarest 1828, thelazia gulosa railliet & henry 1910, and thelazia skrjabini erschow 1928, which occur in many countries; t. gulosa and t. skrjabini have been reported mainly in the new world, while t. rhodesi is particularly common in the old ... | 2004 | 15305729 |
| molecular characterization of thelazia lacrymalis (nematoda, spirurida) affecting equids: a tool for vector identification. | equine thelaziosis caused by the eyeworm thelazia lacrymalis is a parasitic disease transmitted by muscid flies. although equine thelaziosis is known to have worldwide distribution, information on the epidemiology and presence of the intermediate hosts of t. lacrymalis is lacking. in the present work, a pcr-rflp based assay on the first and/or second internal transcribed spacer (its1 and its2) of ribosomal dna was developed for the detection of t. lacrymalis dna in its putative vector(s). the se ... | 2005 | 16038792 |
