Assessing transmission of antimicrobial-resistant Escherichia coli in wild giraffe contact networks
There is growing evidence that anthropogenic sources of antibiotics and antimicrobial-resistant bacteria can spill over into natural ecosystems, raising questions about the role wild animals play in the emergence, maintenance, and dispersal of antibiotic resistance genes. In particular, we lack an understanding of how resistance genes circulate within wild animal populations, including whether specific host […]
Fiber type composition of the plantarflexors of giraffes (giraffa camelopardalis) at different postnatal stages of development
A sample of fibers from deep (close to the bone) and superficial (away from the bone) regions of the plantaris (PLT) and medial (MG) and lateral (LG) gastrocnemius muscles of a neonatal, a 17-day-old and an adult giraffe were typed qualitatively as dark or light based on alkaline preincubation myosin ATPase staining properties and then […]
Note on sleep in captive giraffes (Giraffa camelopardalis reticulata)
The relatively small amount of time spent sleeping by giraffes, can be attributed most directly to the need for constant rumination. This is consonant with the more general ecological notion that sleep patterns in prey species are usually characterized by brief, intermittent periods of sleep.
Complete genomic sequence analyses of the first group A giraffe rotavirus reveals close evolutionary relationship with rotaviruses infecting other members of the Artiodactyla.
Group A Rotaviruses (RVA) have been established as significant contributory agents of acute gastroenteritis in young children and many animal species. In 2008, we described the first RVA strain detected in a giraffe calf (RVA/Giraffe-wt/IRL/GirRV/2008/G10P[11]), presenting with acute diarrhoea. Molecular characterisation of the VP7 and VP4 genes revealed the bovine-like genotypes G10 and P[11], respectively. […]
Developing models for mother–infant behaviour in Black rhinoceros and Reticulated giraffe (Diceros bicornis michaeli and Giraffa camelopardalis reticulata) at Brookfield Zoo, Illinois
For over a decade the behaviours of mothers and newborn calves of Black rhinoceros Diceros bicornis michaeli and Reticulated giraffe Giraffa camelopardalis reticulata have been observed at Brookfield Zoo during the critical first few weeks post-partum. Consistent patterns were seen for individuals within species, allowing models of time budgets, including ranges of variability surrounding each […]
Giraffe Cow-Calf Relationships and Social Development of the Calf in the Serengeti
Activity patterns of giraffe calves and calf-mother distances have been studied as functions of age and sex of the calf in the Serengeti National Park, Tanzania. Particular attention was paid to the nature of the cow-calf bond, suckling behavior, the social development of the calf, relationships between calves and between mother-calf pairs in calf groups, […]
Giraffe mothers in East Africa linger for days near the remains of their dead calves
Repeated investigation of dead young or carrying of corpses has been observed in several mammalian taxa, notably primates [e.g. yellow baboons (Papio cynocephalus): Altmann, 1980; chimpanzees (Pan troglodytes): Goodall, 1986; Matsuzawa, 1997; Biro et al., 2010; ring-tailed lemurs (Lemur catta): Nakamichi, Koyama & Jolly, 1996; Yunnan snub-nosed monkeys (Rhinopithecus bieti): Li et al., 2012), dolphins […]
Ovarian Ultrasonography Correlated with Fecal Progestins and Estradiol During the Estrous Cycle and Early Pregnancy in Giraffes (Giraffa camelopardalis rothschildi)
Fecal and urinary progestin analyses have shown that giraffes express a short reproductive cycle, averaging 15 days, compared with other large ruminants. However, actual ovarian events have not been correlated with the hormonal pattern. In this study, mature cycling female Rothschild giraffes (Giraffa camelopardalis rothschildi) were repeatedly examined by transrectal ultrasonography to correlate ovarian function […]
‘Billy’ bounces back! Nasal tube gives newborn giraffe a second chance AND Live giraffe offspring by AI
A giraffe calf born at Perth Zoo became weak after birth and an indwelling nasogastric tube was placed to allow supplemental feedings. Initial studies for the development of artificial insemination in the giraffe (Giraffa camelopardalis) led to the successful production of a live offspring.
Giraffe Plasma Bank: Protocol 2018
The goal is to reduce neonate mortalities in giraffe under human care by making fresh frozen plasma more widely available to calves with failure of passive transfer. Plasma collection via operant conditioning is ideal due to no anaesthetic agents within the plasma being collected, and highlights the importance of trained blood collection behaviors.
