The ongoing coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a large global outbreak. The reports of domestic animals' infection with SARS-CoV-2 raise concerns about the virus's longer-lasting spread, the establishment of a new host reservoir, or even the evolution of a new virus, as seen with COVID-19. In this review, we focus on the susceptibility of domestic animals, especially companion animals, towards SARS-CoV-2 in light of existing studies of natural infection, experimental infection, and serological surveys.

Exposure to environmental toxicants that affect the immune system and overall health of many mammals is mostly unavoidable. One of the more common substances is the mycotoxins, especially carcinogenic aflatoxin (AF)B which also causes immune suppression/dysregulation in exposed hosts. The present study analyzed the effects of naturally occurring levels of AFB on apoptosis of healthy bovine and camelid neonatal neutrophils (PMN) that were isolated both before and after host consumption of colostrum.

Background: The aim of this study was to investigate the role of oxidative stress in the pathology of ovine dicrocoeliasis.

Methods: During Dec 2013 - Oct 2014, seventy-two sheep (1-3 years) with liver dicrocoeliasis along with 47 healthy sheep were selected from animals admitted for slaughtering at slaughterhouse located in Neyshabour, Razavi Khorasan Province, Iran.

Results: In comparison to healthy control, the malondialdehyde (MDA) level and serum total antioxidant capacity were significantly higher in the parasitized group (<0.

Background: We investigated the variations of heamathologic and biochemical parameters with different parasitic burdens and the correlation between fecal egg counts and fluke number in livers of sheep naturally infected with .

Methods: In order to detect excretion of eggs, fecal samples from 120 sheep of different age groups were collected individually at slaughterhouse in Neyshabur County in Razavi Khorasan Province during December 2013 - October 2014. Hematologic and blood biochemical values in 120 sheep naturally infected with were compared with equivalent values in 120 parasite-free sheep from an organically farmed flock.

Background: This comprehensive study was conducted on multi-purpose one-humped camel (Camelus dromedarius) sera and ticks to assess the epidemiological aspects of the Crimean-Congo hemorrhagic fever virus (CCHFV) in northeast Iran.

Methods: From May 2012 to January 2013, eleven cities were randomly selected in the Khorasan Provinces of Iran as "clusters," and at least 14 one-humped camels were sampled from each area. Reverse transcriptase polymerase chain reaction was used for the detection of the CCHFV genome in ticks.

Article Synopsis
  • The study aimed to find the prevalence of bovine leukemia virus (BLV) in dairy cattle across Khorasan Razavi and Khorasan Shomali provinces in northeastern Iran, examining 429 blood samples.
  • Out of these samples, 25.4% were found to be BLV seropositive, with a notable difference in prevalence between the two provinces: 29.8% in Khorasan Razavi and only 1.5% in Khorasan Shomali.
  • The research indicated that BLV prevalence increased with age, calving frequency, and herd size, suggesting that older animals, those with more calvings, and larger herds are at a higher risk of infection.

Background: All-trans-retinoyl beta-D-glucuronide, a water-soluble glucuronic acid conjugate of all-trans-retinoic acid, has demonstrated high biological activity and low toxicity in most in vitro and in vivo models. Since the reparative effects of retinoids on epithelium are well-known, our aim was to study the effect(s) of intravenously-administered all-trans-retinoyl beta-D-glucuronide in lambs with chronic bacterial bronchopneumonia.

Material/methods: Two groups of lambs were inoculated intrabronchially with either pyrogen-free saline or Mannheimia haemolytica.
