Trichostrongylidae family is considered as a
group of gastrointestinal nematodes of ruminants with widespread distribution
in the world. The parasites are the major causes of productivity loss in many
countries including Iran. This study was carried out to determine the
distribution of abomasal Trichostrongylidae among livestock of Qazvin, Iran.
Totally, 160 abomasum samples including 83 from sheep, 72 from cattle and 5
from goats were collected from slaughterhouses throughout the Qazvin Province.
The ribosomal DNA internal
transcribed spacer 2 (ITS2) region was amplified using PCR
followed by sequencing 13 different isolates. Phylogenetic analysis of the
identified sequences was performed using MEGA 7 software. The prevalence rate
of the nematodes was 19.4% among the specimens. Also, two spices including Marshallagia
marshalli and Teladorsagia circumcincta were identified among the
isolates with M. marshalli at higher frequency. No Trichostrongylus
spp. was detected in the region. Since livestock plays a major role in
ecosystem balance and as some species of nematodes have a zoonotic nature, it
is necessary to proceed with more comprehensive epidemiologic studies to
clarify the infection rate among the human population living in the region.
