The aim of study was to describe clinico histopathological manifestations of cutaneous and gastric habronemiasis in horse. The adult worms live on the wall of the stomach and cutaneous of the host without internal migration. A 5 year old 700 kg warm-blood, cross gelding was referred to the Tehran School of Veterinary Medicine, Veterinary Teaching Hospital. The horse presented skin lesions around. In our survey, several raised granulomatous nodules with a cystic space and parasites within the cysts were observed. Also gastric rupture at greater curvature due to abscess and perforation through the serosa causing diffused peritonitis and subsequent death. Eosinophils and other inflammatory cells were present in large numbers. Furthermore, cutaneous lesions were characterized by single or multiple ulcerated timorous masses with eosinophil epithelioid cell infiltration and scattered necrotic debris. Granulation tissue and neutrophils were observed along the ulcerated area. In this report a case of cutaneous and gastric habronemiasis in a horse in Iran is described with special attention to confirmation of the clinical diagnosis.

A survey was carried out to investigate the prevalence of hard tick species (Acari: Ixodidae) on cattle and sheep north of Iran. The aim of study was to determine the prevalence of hard ticks on cattle and sheep in the mountainous areas of Golestan province and their geographical distribution. A total of 26 ticks were collected from 22 infested cattle and 26 ticks were collected from 12 infested sheep during activating seasons of ticks in 2013-2014. The species collected from cattle and sheep were Hyalomma marginatum, Hyalomma anatolicum, Hyalomma asiaticum, Rhipicephalus bursa and Rhipicephalus sanguineus. The results show that these are dominant tick species in the surveyed area.
