Malignant adipocytic neoplasia is rare among nonhuman primates. We report the gross and microscopic features of a retroperitoneal liposarcoma with myxofibrosarcoma-like dedifferentiation in a free-ranging juvenile golden-headed lion tamarin (Leontopithecus chrysomelas). To our knowledge, this is the first report of such tumor subtype in New World primates.

We report a Microsporum audouinii infection in a female juvenile chimpanzee (Pan troglodytes) presenting generalized dermatitis compatible with dermatophytosis. Dermatophyte was identified by macro- and microscopic characterization of skin and scales cultures in Mycosel Agar. The topical treatment applied was effective, having the potential for dermatophytosis treatment in immunocompetent primates.

INTRODUCTION: Gut microbial communities are critical players in the pathogenesis of obesity. Pregnancy is associated with increased bacterial load and changes in gut bacterial diversity. Sparse data exist regarding composition of gut microbial communities in obesity combined with pregnancy. MATERIAL AND METHODS: Banked tissues were collected under sterile conditions during necropsy, from three non-obese (nOb) and four obese (Ob) near-term pregnant baboons. Sequences were assigned taxonomy using the Ribosomal Database Project classifier...

BACKGROUND: Macaques are outstanding animal models for the development of new contraceptives. In women, progestin-only contraceptives often fail to block ovulation and are believed to act by altering cervix physiology. Herein, we assessed oviductal glycoprotein 1 (OVGP1) in the macaque cervix as a marker for progestogen action. MATERIALS: Rhesus macaques were treated with estradiol (E2 ), E2 plus progesterone (P), and E2 plus levonorgestrel (LNG), a contraceptive progestin...

We investigated menstrual cycles in intrauterine growth restricted (IUGR, 7-10 years, n = 8) and age-matched control (n = 10) baboons. Cycle duration and plasma anti-Mullerian hormone were similar. IUGR spent more days per cycle swollen and had elevated early morning fasted serum cortisol, suggesting normal fertility in the presence of increased psychosocial stress.

The gross anatomy of the palmaris longus muscle in 12 specimens of Saguinus leucopus was studied by dissection. This muscle was constant and unipennate, originated in the medial epicondyle of the humerus; inserted onto flexor retinaculum and palmar aponeurosis; and innerved by the median nerve, and in one case, together with the ulnar nerve. This is the first report of double innervation for this muscle in primates.

BACKGROUND: Retrospective analysis of post-operative vomiting (POV) in non-human primates at our institution was 11%. Based on this additional risk factor for post-operative complications, we aimed to eliminate or decrease POV by adding an antiemetic, maropitant citrate, to the pre-medication protocol. METHODS: Retrospective and prospective data were collected over a 5-year period from 46 macaques of two species during 155 procedures. Additionally, blood was collected from five Macaca mulatta to perform a pharmacokinetic analysis...

Cutaneous neoplasia is common in non-human primates. We describe the gross and microscopic features of multicentric cutaneous keratoacanthomas in a free-living marmoset (Callithrix sp.). Immunohistochemistry for human papillomavirus and herpes simplex virus type I and simplex virus type II was negative. Keratoacanthomas should be included in the differential diagnosis for cutaneous masses in non-human primates.

BACKGROUND: Butyrylcholinesterase (BChE), an enzyme essential for drug metabolism, has been investigated as antidotes against organophosphorus nerve agents, and the efficacy and safety have been studied in cynomolgus macaques. BChE polymorphisms partly account for variable BChE activities among individuals in humans, but have not been investigated in cynomolgus macaques. METHODS: Molecular characterization was carried out by analyzing primary sequence, gene, tissue expression, and genetic variants...
