The jump-yip display of black-tailed prairie dogs (Cynomys ludovicianus) is contagious, spreading through a prairie dog town as 'the wave' through a stadium. Because contagious communication in primates serves to assess conspecific social awareness, we investigated whether instigators of jump-yip bouts adjusted their behaviour relative to the response of conspecifics recruited to display bouts....

It seems I am fighting a two-front war, besieged by three superb scholars. Professors Robert Delahunty and John Yoo,1 and Professor Michael Ramsey2 have authored bracing and challenging responses to Unleashing the Dogs of War (Unleashing).3 Though I have learned from these essays, their authors might say that I have not learned enough because I continue to adhere to the categorical theory’s cla...

Resistant uropathogenic Escherichia coli is the most common cause of urinary tract infections in dogs. The present research was done to study the prevalence rate and antimicrobial resistance properties of UPEC strains isolated from healthy dogs and those which suffered from UTIs. Four-hundred and fifty urine samples were collected and cultured. E. coli-positive strains were subjected to disk di...

A Pseudomonas aeruginosa strain (UCBPP-PA14) is infectious both in an Arabidopsis thaliana leaf infiltration model and in a mouse full-thickness skin burn model. UCBPP-PA14 exhibits ecotype specificity for Arabidopsis, causing a range of symptoms from none to severe in four different ecotypes. In the mouse model, UCBPP-PA14 is as lethal as other well-studied P. aeruginosa strains. Mutations in ...

In order to assess the prevalence of skin diseases in dogs encountered in a first opinion university small animal clinic, 1299 Iranian domestic dogs presented from September 2007 through March 2011 to the Ferdowsi University of Mashhad Veterinary Teaching Hospital, were examined. Dermatological disorders were noted in 17.00% (221/1299) of all the dogs examined. Pruritus was the most common pres...

BACKGROUND Articular cartilage injuries of the knee are among the most debilitating injuries leading to osteoarthritis due to limited regenerative capability of cartilaginous tissue. The use of platelet concentrates containing necessary growth factors for cartilage healing has recently emerged as a new treatment method. OBJECTIVES The efficacy of two types of different platelet concentrates w...

Despite the widespread prevalence of canine parvovirus disease (CPV) in Iranian dog population,molecular diagnosis of CPV variants, and investigation of the trends of its genetic changes is a new effort. Inthis study 50 samples from dogs suspicious of infection with clinical signs of diarrhea and vomiting, and 25samples from dogs suspected of infection with general symptoms su...
