Gastric Hypomotility in Chronic Upper Gastrointestinal Disease of Japanese Macaques (Macaca fuscata)

Gastric hypomotility in chronic upper gastrointestinal disease of Japanese macaques (Macaca fuscata).

Japanese macaques bred indoor for laboratory use often show chronic anorexia and intermittent vomiting. In some of our macaques gastric air was observed on physical examination, and we suspected abnormality of gastric motility. We therefore performed contrast radiographic examinations of the gastrointestinal tract without anesthesia of 8 macaques with gastrointestinal symptoms and 9 asymptomati...

Japanese Macaques (Macaca fuscata) as Natural Reservoir of Bartonella quintana

Bartonella quintana bacteremia was detected in 6 (13.3%) of 45 wild-caught Japanese macaques (Macaca fuscata). Multilocus sequence typing of the isolates revealed that Japanese macaques were infected with a new and specific B. quintana sequence type. Free-ranging Japanese macaques thus represent another natural reservoir of B. quintana.

Energetic consequences of seasonal breeding in female Japanese macaques (Macaca fuscata).

Japanese macaques inhabit a relatively cold environment and females of this species could have developed strategies of energy economy to face the sometimes-harsh seasonal conditions of temperate climates, as well as reproductive costs, and thus regulate their energy balance. Here, we explore the relationship between nutritional status, body composition, seasonality, and reproductive status usin...
