Summary: Long-term, multi-institutional assessments have shown that adult female western lowland gorillas are more vulnerable to wounds compared to males, and group size is associated with increased wounding. However, overall wound rates are low in frequency and severity.

Summary: Since the rise of microbiome research, there has been rapid development in techniques and subfields within the field. Researchers aim to understand microbiome composition and diversity in different hosts for diagnostic use, particularly in zoo settings. This study focused on characterizing individual-level microbiome variation in western lowland gorillas at three zoological institutions.

Summary: The study found a significant negative correlation between group duration and wounding rate in bachelor gorilla groups, indicating lower wounding rates in groups that have been together longer, especially when separated overnight. Additionally, mature silverbacks housed socially overnight sustained significantly more wounds than those housed separately overnight. It is recommended that groups with long social histories or primarily mature members be separated overnight for better care and management.

Summary: This study aims to describe the phylogroups, pathotypes and prevalence of antimicrobial resistance of Escherichia coli isolated from western lowland gorilla's faeces living in MDNP. The results show that these gorillas carry highly resistant E. coli, which may pose a potential risk to human health.

Summary: Spatial and temporal variability in food resources can influence a species' diet, space use, sociality, and life history characteristics. This study examines the diet and nutritional content of western lowland gorillas in different locations, revealing significant variability in their food preferences but similarities in the nutritional composition of major food items. The findings highlight the flexibility of diet in a geographically widespread species and its implications for understanding life history characteristics and conservation management plans.

Summary: The cooperation hypothesis suggests that inequity aversion is a mechanism to identify situations in which cooperation is not paying off, and species that are regularly observed cooperating are more likely to be averse to inequity. Gorillas were found to be more likely to refuse low-value food rewards, indicating a preference for higher rewards rather than a aversion to inequity. Additionally, gorillas were more likely to refuse later in the session, suggesting that testing species on more trials may be beneficial.

Summary: This study investigated the effect of protozoan carriage on psychological symptom severity, and found that there was no significant difference in symptom severity based on the presence of Blastocystis sp. or Dientamoeba fragilis. However, females reported more severe symptoms compared to males across all psychological domains.

Summary: The spatial parameters and design of overnight housing spaces have a significant impact on the behaviors of captive western lowland gorillas. A study conducted at the Detroit Zoo suggests that social overnight housing provides better welfare indicators for gorillas compared to solitary overnight housing. However, separate housing may be an ideal condition for this group at the present time.

Summary: Research on western lowland gorillas showed that habituated gorillas had higher levels of glucocorticoid hormones compared to unhabituated gorillas. These elevated hormones may affect their susceptibility to parasitic infections, particularly in terms of strongylid egg counts.

Summary: This study characterized colonic lesions in captive western lowland gorillas and applied the Nancy index for ulcerative colitis in humans. The colonic changes were comparable to the acute phase of ulcerative colitis in humans, with chronic changes including lymphoplasmacytic infiltrates and crypt dilation or distortion. The Nancy index proved to be a valuable tool for standardizing disease grading.

Summary: Allostatic load, the wear-and-tear organisms accumulate due to senescence and stress, is measured by combining biomarkers into ALIs. The study found a significant positive association between allostatic load and triglycerides, but weaker effect sizes and poorer relative goodness of fit compared to the original ALIs. Multiple methods, including forward stepwise regression and independent biomarker associations, were used to determine the best possible list of biomarkers to include in an index.

Summary: This case report describes a novel occurrence of acute abdominal compartment syndrome (ACS) in a western lowland gorilla during a colonoscopy, without colonic perforation. ACS is a severe condition that requires surgical intervention. While colonoscopy is generally considered safe, serious complications are rare.

Summary: In low-income countries, using lay animal vaccinators to fill the human resource gap in the veterinary sector helps provide animal healthcare services and play a role in the absence of professional veterinarians. The positive outcomes of these programs include increasing farmer knowledge and herd sizes, reducing disease transmission and mortality, and improving vaccination coverage. However, challenges such as opposition from professional veterinarians, stakeholders seeking financial gains, and programming issues are also reported.
