Trichuris Globulosa Von Linstow, 1901 from one-humped camel (Camelus dromedarius) in Egypt: prevalence, morphological and molecular study

Abstract

BackgroundTrichuris spp. (whipworms) are soil-transmitted helminths distributed worldwide, parasitizing several mammalian hosts such as ruminants, primates, and rodents. Trichuris spp. is one of the most common intestinal parasites affecting both humans and animals, and it can spread directly through the fecal-oral route, resulting in severe illness and financial loss. So, this work aims to detect the frequency of Trichuris spp. in camels in Beheira Governorate, Egypt, and to identify Trichuris spp. through morphometrical studies, molecular analysis, and phylogenetic analysis.ResultsA total of 35 dromedaries out of 127 investigated had Trichuris spp. infection, meaning that the overall prevalence was 27.56%. The age of the camel affected the infection rate, older animals (> 5 years) having a higher prevalence of infection (24%) than animals of ages (< 3 years) (20%) than animals of ages (3–5 years) (19.14%). According to season: Trichuris spp. showed a unique pattern in camels in different seasons: summer (31.25%) > autumn (28.13%) > spring (25.8%) > winter (25%) indicating year-round infection. T. globulosa was identified morphometrically from camels in Beheira Governorate, Egypt. The BLAST analysis revealed the presence of T. globulosa isolate from camels using the Genbank database depending on nuclear small subunit ribosomal RNA (18s) and cytochrome b (Cytb) genes.ConclusionA high prevalence of T. globulosa was found in camels in Beheira Governorate, Egypt. This is the first report to confirm the identification of T. globulosa from camel based on morphometrical studies and molecular and phylogenetic analysis in Egypt. More thorough studies on the incidence, molecular, and genetic analysis of Trichuris spp. in Egypt are required in addition to camel control programs.
