Fatal Herpesvirus Encephalitis in a Reticulated Giraffe (Giraffa camelopardalis reticulata)

Fatal meningoencephalitis caused by equine herpesvirus-1 (EHV-1) was diagnosed in a reticulated giraffe (Giraffa camelopardalis reticulate). The giraffe died following a history of stumbling, incoordination, and abdominal pain. Gross examination of the brain revealed asymmetric edema and red-brown discoloration, predominantly within the telencephalon. Microscopically, there was perivascular lymphohistiocytic cuffing, multifocal gliosis, and neuronal necrosis in the cerebrum. Necrotic neurons contained acidophilic intranuclear inclusions. EHV-1 was isolated from the brain of the giraffe, and polymerase chain reaction was positive on sections

A preliminary investigation into comparative foraging ecology of reticulated giraffe (Giraffa camelopardalis reticulata) and domestic camels (Camelus dromedarius) in Laikipia Kenya

Female camels actively browse over a wide range of heights, from ground level up to 3 meters. Traditionally, due to their being browsers, their dispersal ability and elevated foraging level, giraffes have been thought to be able to co-exist with traditional pastoralist livestock species. However, with the introduction of the larger and taller browsing camels, could this alter the status quo, and potentially affect giraffes’ ability to co-exist with livestock? Due to time and budget constraints, this study gathered baseline

Colonic obstruction in three captive reticulated giraffe (Giraffa camelopardalis reticulata)

Fatal colonic obstructions were diagnosed in three captive, adult, reticulated giraffe (Giraffa camelopardalis reticulata). Clinical presentations varied, but all cases displayed decreased activity, anorexia, and considerably decreased fecal production, consistent with intestinal obstruction. Case 1 was diagnosed at necropsy with a phytobezoar obstructing the spiral colon. Case 2 was diagnosed at necropsy with a fecal impaction of the colon. Case 3 was diagnosed during surgery with colonic ileus. Cases 2 and 3 underwent surgical intervention but were markedly compromised by

Arthroscopic surgery in a reticulated giraffe (Giraffa camelopardalis reticulata)

An 8-month-old captive male reticulated giraffe (Giraffa camelopardalis reticulata) developed an acute lameness (grade IV/V) of the right forelimb, with swelling of the metacarpophalangeal joint. A traumatic injury was suspected based on clinical, radiographic, and arthroscopic evaluation. Several abnormalities were identified arthroscopically, including synovitis, cartilage damage, and an osteochondral fragment. Medial collateral ligament damage was also suspected based on radiographic evaluation. Arthroscopy provided a means of diagnosis and treatment of the abnormalities identified. The lameness in this giraffe resolved within

Multilevel social organization and space use in reticulated giraffe (Giraffa camelopardalis)

It is increasingly recognized that association patterns of most gregarious animals are nonrandom. However, nonrandom patterns can emerge in any population that exhibits spatial structure, even if individuals associate randomly. In species that lack clearly differentiated social relationships characteristic of socially complex mammals, space use patterns must be considered alongside association patterns in order to establish whether nonrandom association patterns are determined by underlying social structure or are merely an artifact of spatial structure. In this study, we simultaneously consider

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 behaviour, to be developed. Once the model is created any data collected for neonates can be compared to the mean values in the model so

Necks and networks: a preliminary study of population structure in the reticulated giraffe (Giraffa camelopardalis reticulata de Winston)

This paper describes a method of scoring the neck pattern of reticulated giraffes as a simple code that can be searched for in an Excel spreadsheet. This enables several hundred individual giraffe to be recognized and repeatedly found within a database. Possible sources of error are described and quantified. Data on group size, dispersal within groups and social network patterns are described. The latter is facilitated using Ucinet 6.85 for Windows, a software package that helps to visualize and analyse

Foraging ecologies of giraffe (Giraffa camelopardalis reticulata) and camels (Camelus dromedarius) in northern Kenya: effects of habitat structure and possibilities for competition?

The foraging ecologies of reticulated giraffe (Giraffa camelopardalis reticulata) and domestic camels (Camelus dromedarius) were examined in the Laikipia District of Kenya, where these species have recently become sympatric. Camels increased popularity in the region has lead to concerns about their environmental impacts and possible competition with wild giraffe for resources. We gathered foraging data on both species using 2-min group scans that recorded feeding heights and plant food preferences. Transects sampled the vegetation in areas where foraging observations were

Foraging ecologies of giraffe and camels in Northern Kenya: Effects of habitat structure and possibilities for competition?

Domestic camels (Camelus dromedarius) have become increasingly popular livestock in arid regions of sub-Saharan Africa. However, little is known about the environmental impacts of these animals, and concern has been mounting about possible competition with wild native ungulates. Unlike the more traditional pastoralist livestock species, camels are large-bodied, long-necked browsers which increases the potential to overlap with wild giraffe foraging, especially as the space available for browsing decreases. Giraffe ecology and social dynamics are poorly understood; it is believed that
