The leopard (Panthera pardus) as an adaptable felid widely distributed in varied ecosystems of Iran. The Golestan Natural Park is one of the main habitats of leopard in the country. It has divers diet and preying various types of preys such as wild ungulate and livestock. The prey remains’ samples of leopard were collected and preserved using ethanol 96% and whole genomic DNA was extracted. The...

The domestic dog varies remarkably in cranial morphology. In fact, the differences in size and proportion between some dog breeds are as great as those between many genera of wild canids. In this study, I compare patterns of intracranial allometry and morphologic diversity between the domestic dog and wild canid species. The results demonstrate that the domestic dog is morphologically distinct ...

A serosurvey of rabies antibodies among domestic dogs (Canis familiaris, n = 178), spotted hyaenas (Crocuta crocuta, n = 72) and African wild dogs (Lycaon pictus, n = 18) of the Masai Mara, Kenya, was carried out. Rabies antibodies were found in 9.6% of the domestic dog sera, but all wild dog and hyaena sera were negative. Rabies has been confirmed in this region among the above species as well...

Within some of these buildings it seems that time has taken a giant step backwards. The figures bent over their computer consoles are engaged in much the same quest as the frock-coated microscopists and Dodo-stuffers of bygone years; they are today's taxonomists, though their raw materials are of course sequences rather than morphological features, and statistical models and ingenious computer ...

The origin of the domestic dog from wolves has been established, but the number of founding events, as well as where and when these occurred, is not known. To address these questions, we examined the mitochondrial DNA (mtDNA) sequence variation among 654 domestic dogs representing all major dog populations worldwide. Although our data indicate several maternal origins from wolf, >95% of all seq...

Progressive rod-cone degeneration (PRCD) is an autosomal recessive disease caused by c.5G>A mutation of the PRCD exon 2. This mutation has been identified in various breeds, including Labrador Retriever. The present study aimed to examine the allelic frequency of PRCD in Labrador Retrievers in Japan. A domestic and a guide dog population were genotyped for PRCD using polymerase chain reaction-r...

To provide molecular and virologic evidence that domestic dog rabies is no longer enzootic to the United States and to identify putative relatives of dog-related rabies viruses (RVs) circulating in other carnivores, we studied RVs associated with recent and historic dog rabies enzootics worldwide. Molecular, phylogenetic, and epizootiologic evidence shows that domestic dog rabies is no longer e...

Rabies is an acute, fatal viral disease that infects domestic and wild animals and is transmissible to humans. Worldwide, rabies kills over 55,000 people every year. The domestic dog plays a pivotal role in rabies transmission. Domestic dogs are not only part of our daily lives but also of our immediate surroundings, and this is reflected in the rise in pet dog ownership in developed and develo...

The domestic dog was probably the first domesticated animal, and the only one to spread to all continents in ancient times. The dog is one of the most phenotypically diverse animals, a result of human selection throughout dog history. Studies of the genetic origins and early spread of domestic dogs is important to gather information about biological and cultural mechanisms behind domestication ...
