Abstract

A cross-sectional study was carried out to determine the prevalence, the intensity, infection, clinical sign, to identify species and to investigate associated risk factors of thelaziosis in cattle in Kupang district, Nusa Tenggara Timur Province. A total of 385 head of cattle were randomly selected from 96 farms in three subdistricts of Kupang District and observed for thelaziosis. The nematode present in the eye of cattle were collected with a forcep after administering local anesthesia (10% Xylocaine). The potential risk factors related to age of cattle, human resources and farm management were obtained by interviewing the farmers. Logistic regression was applied to analyze related risk factor of thelaziosis. The result showed that of the total 385 cattle observed, 23 (5.96%) were infected by Thelazia spp., of which 22 cattle showed apparent clinical signs namely excessive lacrimation and conjunctivitis that led to keratoconjunctivitis, while one cattle showed ulceration. A total of 357 worms (157 males and 210 female) were collected from 23 infected cattle with the mean number of worms in infected cattle being 32.92 ± 21.03. Observations on morphological characteristics using Scanning Electron Microscope (SEM) helped to ide...Continue Reading
