Testosterone plays a crucial role in regulating sexual behavior among non-human primates, working primarily by increasing copulatory behavior and sexual motivation. In this study, we analyzed fecal testosterone levels in five adult male Tibetan macaques (Macaca thibetana) living freely in the Huangshan National Reserve in Anhui Province. The aim was to investigate the relationships between fecal testosterone levels and sexually motivated behaviors.
Methods
We collected a total of 426 fecal samples and observed approximately 453 h of focal sampling behavioral data. Sexually motivated behaviors were categorized as sexual chase, grimace, and sexual-inspection.
Results
The results showed a positive correlation between sexually motivated behaviors and copulatory behavior. Furthermore, all the three sexually motivated behaviors, including sexual chase, grimace, and sexual-inspection, were positively correlated with fecal testosterone levels.
Conclusion
Our results demonstrated positive correlations between sexually motivated behaviors and fecal testosterone in free-ranging Tibetan macaques.

Background
Oral cavity squamous cell carcinomas (OCSCCs) are relatively common in multiple non-human primate species but are poorly documented in Goeldi's monkeys.
Methods
Four Goeldi's monkeys with OCSCC, from three zoological collections, underwent necropsy with cytology, histopathology, immunohistochemistry, and pan-herpesvirus PCR analysis.
Results
All animals were euthanised and exhibited poor-to-emaciated body condition. Three OCSCCs arose from the maxillary oral mucosa and a single OCSCC was primarily mandibular, with bone invasion evident in three cases. Histologically, one OCSCC in situ was diagnosed, whilst the rest were typically invasive OCSCCs. Neoplastic cells were immunopositive for pancytokeratin and E-cadherin. All examined cases were negative for regional lymph node (RLN) and/or distant metastases, cyclooxygenase-2 (COX-2) immunoexpression, and panherpesvirus PCR expression.
Conclusions
OCSCCs in Goeldi's monkeys may be deeply invasive, but not readily metastatic. No herpesvirus-association or COX-2 expression was evident; the latter suggesting that NSAIDs are unlikely to be a viable chemotherapeutic treatment.

Background
Platynosomiasis in non-human primates kept under human care causes chronic disease of the bile ducts and liver, which initially presents with nonspecific signs and can culminate in the death of the animal. Diagnosing this disease is a challenge, and an ultrasound examination can be an excellent tool when it is suspected.
Methods
This study describes the ultrasound findings from 57 marmosets with suspected infection by Platynosomum sp., the correlated hepatobiliary changes, and the anatomopathological findings that confirmed the occurrence of platynosomiasis.
Results
In six marmosets (one C. aurita, two C. jacchus, and three Callithrix sp.), Platynosomum infection was confirmed macroscopically (presence of adult trematodes in the gallbladder) and microscopically (adults, larvae, and eggs in histological examinations and eggs in bile and feces). These findings were compatible with the hepatobiliary changes and with images suggestive of parasitic structures in ante-mortem assessments.
Conclusion
Ultrasound examination demonstrated its usefulness within the clinical routine for investigating this parasitosis.
背景：在人类看护下饲养的非人灵长类动物患上板吸虫病会导致胆管和肝脏慢性疾病，最初表现为非特异性症状，最终可能导致动物死亡。诊断这种疾病是一项挑战，而超声波检查则是怀疑这种疾病时的极佳工具：本研究描述了 57 只疑似感染板吸虫的狨猴的超声波检查结果、相关的肝胆变化以及证实发生板吸虫病的解剖病理结果：结果：在六只狨猴（一只 C. aurita、两只 C. jacchus 和三只 Callithrix sp.）中，经宏观（胆囊中存在成虫）和微观（组织学检查中的成虫、幼虫和虫卵以及胆汁和粪便中的虫卵）证实感染了板吸虫。这些发现与肝胆变化以及死前评估中提示寄生虫结构的图像相符：结论：超声波检查证明了其在临床常规检查中的实用性。

A critical turning point was reached in research with the recent success in cloning rhesus monkeys (Macaca mulatta), a major advancement in primatology. This breakthrough marks the beginning of a new age in biomedical research, ushered by improved somatic cell nuclear transfer techniques and creative trophoblast replacement strategies. The successful cloning of rhesus monkeys presents the possibility of producing genetically homogeneous models that are highly advantageous for studying complex biological processes, testing drugs, and researching diseases. However, this achievement raises important ethical questions, particularly regarding animal welfare and the broader ramifications of primate cloning. Approaching the future of primate research with balance is critical, as the scientific world stands on the brink of these revolutionary breakthroughs. This paper aims to summarise the consequences, ethical challenges and possible paths forward in primatology arising from rhesus monkey cloning.

A senile male black capuchin monkey (Sapajus nigritus) kept under human care in a Zoo was found dead after 2 weeks presenting signals of weight loss and hyporexia. Histopathological revealed a necrotizing encephalitis. Although it was not observed microscopically, Sarcocystis sp infection was detected in brain tissue from molecular assays. These infections have been rarely described in neotropical primates, particularly associated with tissue lesions.

Background
This study used infrared thermography (IRT) for mapping the facial and ocular temperatures of howler monkeys, to determine parameters for the diagnosis of febrile processes. There are no published IRT study in this species.
Methods
Were evaluated images of a group of monkeys kept under human care at Sorocaba Zoo (São Paulo, Brazil). The images were recorded during 1 year, in all seasons. Face and eye temperatures were evaluated.
Results
There are statistically significant differences in face and eye temperatures. Mean values and standard deviations for facial and ocular temperature were respectively: 33.0°C (2.1) and 36.5°C (1.9) in the summer; 31.5°C (4.5) and 35.3°C (3.6) in the autumn; 30.0°C (4.3) and 35.6°C (3.9) in the winter; 30.8°C (2.9) and 35.5°C (2.1) in the spring.
Conclusions
The IRT was effective to establish a parameter for facial and ocular temperatures of black-and-gold howler monkeys kept under human care.

Although critical to the overall condition of animals under human care, there is still limited information about oral health in neotropical primates.
Methods
We analyzed the main oral conditions and microbiota using mass spectrometry from 13 capuchin monkeys (Sapajus apella) under human care. The findings were registered on odontograms following the Triadan system.
Results
The most prevalent conditions were dental fractures (n = 9), mainly enamel fractures, and periodontal disease (n = 8), mainly grade 1 calculi. When exanimating teeth, alterations were identified in 90 out of the 416 evaluated pieces, being periodontal disease the most common (n = 60), followed by enamel fracture (n = 15) and missing teeth (n = 10). In the oral microbiota analyses, Staphylococcus and Streptococcus species were the most prevalent, although no obvious association was observed between isolated organisms and oral conditions.
Conclusions
These findings hold the potential to prevent oral disorders, including fractures and periodontal diseases, contribute to molecular identification of oral microbiota, and to improve the well-being of primates under human care.

In the oral microbiota analyses, <i>Staphylococcus</i> and <i>Streptococcus</i> species were the most prevalent, although no obvious association was observed between isolated organisms and oral conditions.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>These findings hold the potential to prevent oral disorders, including fractures and periodontal diseases, contribute to molecular identification of oral microbiota, and to improve the well-being of primates under human care.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16439,"journal":{"name":"Journal of Medical Primatology","volume":"53 3","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141081544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
