Quantification and risk factor analysis of elephant endotheliotropic herpesvirus-haemorrhagic disease fatalities in Asian elephants (Elephas maximus) in Europe (1985-2017) (Perrin et al., 2021)
The endotheliotropic herpesvirus-haemorrhagic disease (EEHV-HD) is a major cause of death in captive Asian elephants and increasingly recognised in their wild counterparts as well. A risk factor analysis of this disease in Europe (1985-2017) found the following:
✔EEHV-HD accounted for 57% of Asian elephant deaths;
✔Median age of EEHV-HD deaths: 2.6 years;
✔Similar risk for ♂ & ♀ ;
✔Only significant risk factor identified was a previous EEHV-HD death in the institution;
✔Exposure to new elephants was not a significant risk factor.
Monitoring great ape heart health through innovative electrocardiogram technology: Training methodologies and welfare implications (Cloutier Barbour et al., 2020)
Heart disease is a major cause of mortality in zoo-housed great apes. A study in Zoo Biology introduced a electrocardiogram technology that facilitates the monitoring of great ape heart health: ✔Kardiamobile allows for voluntary, instant, reliable & economic electrocardiogram readings; ✔Operant conditioning training guidelines provided; ✔System generates evidence to inform management regarding great ape heart health.
A Retrospective Study of Macropod Progressive Periodontal Disease (“Lumpy Jaw”) in Captive Macropods across Australia and Europe: Using Data from the Past to Inform Future Macropod Management (Rendle et al., 2020)
New research looked into "lumpy jaw" disease in captive macropods: ✔High mortality (62.5% for Australian & European institutions); ✔Risk of developing the disease increased with age; ✔Different incidence rates & risk of infection between institutions and geographic regions; ✔Recommendations to reduce disease risk were provided.
