Albinism, Partial Albinism, and Vitiligo
Albinism, partial albinism, and vitiligo are three clinically distinct conditions having in common a deficiency of melanin pigment. As such they present the physician with the same basic problems-cosmetically disfiguring lesions and extreme sensitivity to sunlight of the involved areas. None of the diseases is itself an immediate threat to life, but the social disabilities, especially among dar...
متن کاملOculocutaneous albinism
Oculocutaneous albinism (OCA) is a group of inherited disorders of melanin biosynthesis characterized by a generalized reduction in pigmentation of hair, skin and eyes. The prevalence of all forms of albinism varies considerably worldwide and has been estimated at approximately 1/17,000, suggesting that about 1 in 70 people carry a gene for OCA. The clinical spectrum of OCA ranges, with OCA1A b...
متن کاملAlbinism: modern molecular diagnosis.
Albinism is no longer a clinical diagnosis. The past classification of albinism was predicated on phenotypic expression, but now molecular biology has defined the condition more accurately. With recent advances in molecular research, it is possible to diagnose many of the various albinism conditions on the basis of genetic causation. This article seeks to review the current state of knowledge o...
متن کاملBiliary cryptosporidiosis in two corn snakes (Elaphe guttata).
Cryptosporidia are 5-7-mm apicomplexid coccidian parasites that infect humans and many other species of mammals, birds, reptiles, and fish. In humans and cattle, infection by Cryptosporidium parvum usually affects the intestinal tract, resulting in self-limiting diarrhea.4 Respiratory and intestinal cryptosporidiosis occur in birds infected with C. bayleyi and C. meleagridis.5 Sneezing, coughin...
متن کاملGenetic evidence for sexual selection in black ratsnakes, Elaphe obsoleta
We investigated benefits of polyandry and phenotypic correlates of male mating success in black ratsnakes. We used 10 microsatellite loci to identify the sires of 375 hatchlings from 34 clutches with known mothers. Multiple paternity occurred in 88% of clutches, despite the fact that ratsnakes mate when dispersed. The incidence of multiple paternity did not vary with female size or with clutch ...
