the aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. a 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. the dog was bitten by a snake nearly 4 months ago. a 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. in the left eye, posterior synechia was detected in the ...

Extensive genetic resources and a high-quality genome sequence position the dog as an important model species for understanding genome evolution, population genetics and genes underlying complex phenotypic traits. Newly developed genomic resources have expanded our understanding of canine evolutionary history and dog origins. Domestication involved genetic contributions from multiple population...

Dogs naturally suffer the same complex diseases as humans, including mental illness. The dog is uniquely suited as a model organism to explore the genetics of neuropsychiatric disorders. Historical breed demographics have enriched purebred populations for founder effect mutations with tractable architectures, making genotypic analyses advantageous. Over a pet’s lifetime, owners observe the anim...

in this study 74 stray dogs including 39 females and 35 males with cooperation of dog killing team of municipality were killed, examined macroscopically and microscopically in kerman city from 1992 to 1993. taenia hydatigena was the most prevalent helminth observed in 57 dogs (77%), dipylidium caninum in 13 dogs (17.6%), echinococcus granulosus in 5 dogs (6.8%) and toxocara canis in one dog (1....

introduction and goal: today, the researchers have found that many recent diseases are due to cellular oxidative stress which is caused by the imbalance of the formation and neutralization of free radicals. including weak immune system, cancers, inflectional diseases, aging body and diabetes. diabetes is the most common endocrine disease in the world that is referred to as the mother of the dis...

tramadol is a synthetic, centrally acting opioid analgesic that has the best analgesic efficacy without excessive sedation and significant side effects in the postoperative pain relief in dogs. objectives: in this study, hematological and biochemical changes due to short usage of tramadol were assessed in clinically healthy dogs. methods: for this purpose, eighteen male mongrel dogs aged 14 to ...

a 3-month-old short haired pointer with crusty local alopecia around the eyes was presented to smallanimal hospital of tehran university. scraping and biopsy were obtained from lesions of affected area.notoedres sp. was diagnosed in skin scraping by parasitologic examination. furthermore, histopathology oflesions demonstrated moderate hyperplastic epidermis, parakeratosis and acanthosis.

in the present study, we describe a subcutaneous mass between the left flank and hip in a 2-year-old male great dane dog. histopathologically, cells appeared to be spindle shaped around a central capillary together with a fingerprint pattern. immunohistochemical analysis presented that the neoplastic cells expressed vimentin, but did not stain for s-100 protein. on the basis of histopathology a...

Human rabies in developing countries can be prevented through interventions directed at dogs. Potential cost-savings for the public health sector of interventions aimed at animal-host reservoirs should be assessed. Available deterministic models of rabies transmission between dogs were extended to include dog-to-human rabies transmission. Model parameters were fitted to routine weekly rabid-dog...
