Spontaneous Vitiligo in a Captive Rhesus Monkey ().

Vitiligo affects a significant portion of human and animal populations. The disease causes irregular and multifocal progressive loss of fur, skin, and mucous membrane pigmentation due to the loss or absence of melanocytes. While etiopathogenesis is not completely understood, autoimmunity, environmental, and genetic factors are implicated We present a case report on a 16-y-old female rhesus macaque ( ) with depigmented areas that are progressively increasing on the skin and coat and are distributed on the head and back.

Congenital adactyly and oligodactyly with metatarsal hypoplasia in two rhesus monkeys.

Congenital digital defects, particularly adactyly and oligodactyly, have been reported frequently in humans, however, their occurrence in rhesus monkeys is rare, mainly in the hind limbs. We present here for the first time, two female rhesus monkeys with unilateral congenital toe defects with metatarsal involvement. One showing adactyly and the other oligodactyly.

Orofacial Deformities in 3 Related Rhesus Monkeys () Resembling Human Binder's Syndrome.

Binder's syndrome is a rare congenital deformity characterized by midface hypoplasia, particularly around the nasomaxillary area. Genetic etiology or developmental failure caused by prenatal exposure to teratological agents has been considered. In this article, we present 3 related rhesus monkeys born with orofacial deformities similar to those found in infants with the Binder phenotype.

COVID-19 Vaccine and Social Media in the U.S.: Exploring Emotions and Discussions on Twitter.

The understanding of the public response to COVID-19 vaccines is the key success factor to control the COVID-19 pandemic. To understand the public response, there is a need to explore public opinion. Traditional surveys are expensive and time-consuming, address limited health topics, and obtain small-scale data.

Congenital short tail in Macaca mulatta.

In a captive Macaca mulatta breeding colony, a single family group with 39 animals showed 19 individuals being born with dramatic tail shortening. Through clinical, genealogical, radiographic, and cytogenetic evaluation, it was related to a probable dominant autosomal inheritance of the reduction in the number of distal caudal vertebrae.
