Solitary patent ductus arteriosus in a Japanese macaque (Macaca fuscata)
( Young-jin Jang ),( Byung-yong Park ),( Hyun-jin Tae ),( Jeoungha Sim ),( Dongchoon Ahn ) 한국동물위생학회 2023 韓國家畜衛生學會誌 Vol.46 No.4
Patent ductus arteriosus (PDA) in monkeys is very rare. A 9-year-old male Japanese macaque (Macaca fuscata) had an hourglass-shaped PDA with a large luminal diameter. Morphological analysis of the vessel cast and heart revealed cardiovascular pathological changes including pulmonary artery hypertension and right ventricular hypertrophy. However, left ventricle hypertrophy or left atrial enlargement were not observed. This macaque had showed no clinical signs of PDA during its lifetime. We present the first documented case of solitary PDA in a male macaque.

Natural habitat fragmentation and reducing habitat quality have resulted in an increased appearance of Japanese macaques, Macaca fuscata (Gray, 1870), in suburban areas in Japan. To investigate the risk of zoonotic infections, a coprological survey of helminth eggs passed by wild Japanese macaques was carried out in 2009 and 2010 in Shiga Prefecture, Japan. Microscopic examination found helminth eggs in high prevalence, and nucleotide sequencing of DNA extracted from the eggs identified Oesophagostomum cf. aculeatum and Trichuris trichiura. A fecal culture also detected infective larvae of Strongyloides fuelleborni. These zoonotic nematodes pose a potential health issue to local people in areas frequented by Japanese macaques.

Hematological and serum biochemical values were assessed from 20 clinically healthy Japanese Macaques raised in Everland Zoological Gardens and compared to the International Species Information System (ISIS) reference range that is used internationally as standard for wildlife animals. Taking our standard on sexual maturation at age 4, tRBC values in Macaques under age 4 were significantly lower than those over age 4, but the Hb and PCV values were significantly higher. Compared to the ISIS standard, the tRBC values in Macaques under age 4 were significantly lower whereas the Hb and MCHC values were significantly higher. Moreover, in the samples of Macaques over age 4, the PCV and MCV values were significantly lower than the ISIS standard. On serum biochemistry values the creatinine and amylase values in the Macaques under age 4 were significantly lower than those over age 4. In comparison with the ISIS standard, the values of ALT, ALP, BUN, IP, Ca2+ and K+ in the Macaques under age 4 did have no significant difference. The values of TP, GGT, tBil, amylase, TG and UA were significantly higher than the ISIS standard, but the values of albumin, AST, glucose, creatinine, cholesterol, CPK, LDH, Na+ and Clwere significantly lower. In contrast, the values of TP, albumin, ALT, ALP, creatinine, cholesterol, amylase, TG, IP and Na+ in the Macaques over age 4 did have no significant difference, but the values of GGT, BUN, tBil, UA and Ca2+ were significantly higher, while the values of AST, glucose, CPK, LDH, K+ and Cl- were significantly lower. On the other hand, there was no significant difference in hematological and serum biochemical values between the groups of male and female.

To evaluate the effects of Zoletil (tiletamine- zolazepam) that have been widely used for the chemical restraint and anesthesia of primates, on physiologic alteration, blood gas analysis and anesthetic duration in the Japanese macaque(Macaca fuscata), this study was carried out. Zoletil was administered by intramuscular injection. Evaluation of temperature, heart rate, respiration rate and blood gas analysis were performed before administration and at 1, 10, 20, 30, 40, 50 and 60 min after administration, and induction and maintenance time was recorded. There was no significant difference in heart rate, $PCO_2$, $PO_2$ after Zoletil administration rut temperature, respiraticn rate, pH were significant difference compared with these of Mere administration. The induction time was $2.5{\pm}1.0min$ and maintenance time was $86{\pm}23.2min$. It was considered that Zoletil could be usefully used for the sedation and immobilization of Japanese macaque reared in zoological garden.

There was a mass outbreak of death caused by transport stress and malnutrition in Japanese macaques imported from Japan at a farm stock in Korea, which were diagnosed on the ground of history taking, clinical finding, hematological examination and necropsy. Twenty eight Japanese macaques imported from Japan died suddenly from the 4th day after arrival in a farm. These animals were confined very small cages individually and lose the appetite for 10 days from shipping. Main clinical findings observed from alive Japanese macaques consisted of hypothermia and dehydration. On hematological observation for typical 4 cases showed increased erythrocytes and packed cell volume. On serum biochemical examination for 3 cases showed hypoglycemia, whereas blood urea nitrogen, aspartate aminotransferase and alanine aminotransferase were increased. On necropsy for 3 cases, hemorrhage and congestion were observed on the lung and the walls of stomach and intestine were thinned. Histologically, hemorrhagic pneumonia and enteritis with loss of villi were seen. The death of these animal was caused by poor management during transport, which was resulted in transport stress and malnutrition.
