“…These three Chinese raccoon dog chromosomes are well defined both according to the nomenclature of Pieńkowska et al (2002a) and Nie et al (2003). FISH conditions and detection of signals were identical to the ones for the human NOR probe and the blue fox Y chromosome painting probe with the only exception that the hybridization time was 72 h.…”

“…Moreover, there are great difficulties in repeatedly getting the blood or other tissues from the majority of canid species, even if the animals are kept in captivity. As a result, standardised karyotypes are available only for four species: the blue fox (Mäkinen et al, 1985a), the red fox (Mäkinen et al, 1985b), the domestic dog (Switonski et al, 1996;Breen et al, 1999) and the Chinese raccoon dog (Pieńkowska et al, 2002a). In addition, for the Japanese raccoon dog detailed data on its chromosomes have been generated through extensive G-banding and comparative chromosome painting experiments (e.g.…”

We have analysed the chromosomes of three wild and endangered canid species: the maned wolf (Chrysocyon brachyurus), the bat-eared fox (Otocyon megalotis) and the fennec fox (Fennecuszerda) using classical and molecular cytogenetic methods. For the first time detailed and encompassing descriptions of the chromosomes are presented including the chromosomal assignment of nucleolar organizer regions and the 5S rRNA gene cluster. We propose a karyotype nomenclature with ideograms including more than 300 bands per haploid set for each of these three species which will form the basis for further research. In addition, we propose four basic different patterns of karyotype organization in the family Canidae. A comparison of these patterns with the most recent molecular phylogeny of Canidae revealed that the karyotype evolution of a species is not always strongly connected with its phylogenetic position. Our findings underline the need and justification for basic cytogenetic work in rare and exotic species.

In the present report we show the chromosomal localization of two BAC clones, carrying the leptin (LEP) and insuline-like growth factor 1 (IGF1) genes, respectively, in four species belonging to the family Canidae: the dog, red fox, arctic fox and the Chinese raccoon dog. The assignments are in agreement with earlier data obtained from comparative chromosome painting for the dog, red fox and arctic fox.

“…But the karyotype of Chinese Raccoon dog (2n = 54 + B) reported to be composed of five pairs of bi-armed autosomes and 21 pairs of acrocentric autosomes, two bi-armed sex chromosomes and in addition, a variable (1 to 4) number of B chromosomes, with a total of 231 bands in A set of chromosomes (Ma¨kinen, 1986). The G banding of Chinese dog also revealed medium sized metacentric X chromosome and smallest subtelocentric Y chromosome and reported to have three types of B i.e., BI, BII and BIII chromosomes which resembles the Japanese Raccoon dogs (Pieñkowska, 2002). The banding pattern observed in the study enables for precise identification of (Table 2).…”

Rajapalayam, an important dog breed of southern India which are maintained for guarding of farm houses and protection from wild animals. The aim of the present investigation is to study the karyology of this important dog population for cytological profiling. Metaphase plates were prepared after culturing of lymphocytes isolated from heparinized blood collected from animals of both the sexes. Giemsa banding, centromeric index, arm ratio and relative length were estimated through standard protocol. The cytogenetic profile of Rajapalayam dog is different from that of Chinese Raccoon and Japanese Raccoon dogs which belongs to Canidae family with a basic chromosome number of 78 without B chromosome. The X chromosomes are longer in bitches than that of in dogs. Giemsa banding analysis revealed higher number of bands (272) distributed among the 38 chromosome in Indian dog breed as compared to that Chinese Raccoon dog. The results of the present study gave insight knowledge to the researchers, dog breeders and kennel clubs about the karyology of Indian dog breeds and to know about any chromosomal abnormalities which may leads to fertility, growth and phenotypic abnormality related problems in this dog breed.
