“…However, these findings are not validated in roan antelope, and the effects of pathogenic theileriosis on platelets have not been investigated in other wild antelope species. Although hematologic reference values exist for a variety of wild artiodactyl species in captivity and in the wild, 39,[149][150][151][152] testing methods need to be standardized to allow for accurate inference over diverse species. 165…”

The Pathology of Pathogenic Theileriosis in African Wild Artiodactyls

The published literature on schizont-“transforming,” or pathogenic theileriosis, in African wild artiodactyls is dated and based on limited information. Here the authors review the taxonomy, diagnosis, epidemiology, hematology, pathology, and aspects of control in various species. Molecular studies based on 18S and 16S rRNA gene sequences have shown that African wild artiodactyls are commonly infected with diverse Theileria spp., as well as nontheilerial hemoprotozoa and rickettsia-like bacteria, and coinfections with pathogenic and nonpathogenic Theileria species are often recorded. Although theileriosis is still confusingly referred to as cytauxzoonosis in many species, the validity of a separate Cytauxzoon genus in artiodactyls is debated. The epidemiology of theileriosis is complex; the likelihood of fatal disease depends on the interplay of parasite, vertebrate host, tick vector, and environmental factors. Roan calves ( Hippotragus equinus) and stressed animals of all host species are more susceptible to fatal theileriosis. Even though regenerative anemia is common, peripheral blood piroplasm parasitemia does not correlate with disease severity. Other than anemia, common macroscopic lesions include icterus, hemorrhages (mucosal, serosal, and tissue), fluid effusions into body cavities, lung edema, and variably sized raised cream-colored foci of leukocyte infiltration in multiple organs. Histopathologic findings include vasocentric hyperproliferation and lysis of atypical leukocytes with associated intracellular schizonts, parenchymal necrosis, hemorrhage, thromboembolism, and edema. Immunophenotyping is required to establish the identity of the schizont-transformed leukocytes in wild ungulates. Throughout the review, we propose avenues for future research by comparing existing knowledge on selected aspects of theileriosis in domestic livestock with that in African wild artiodactyls.

“…Haematological and biochemical analyses were found to be within normal limits for antelopes with a haematocrit of 49.4% (Pospísil et al 1984 ; Vahala & Kase 1993 ). Pre-operative medication included amoxicillin clavulanic acid (10.5 mg/kg bodyweight [bwt]: Augmentin, Glaxo Smith Kline, Johannesburg, South Africa), meloxicam (2 mg/kg bwt: Metacam, Boehringer Ingelheim, Randburg, South Africa), hyoscine butyl bromide (4 mg/kg bwt: Buscopan, Boehringer Ingelheim, Randburg, South Africa) and butorphanol tartrate (0.05 mg/kg bwt: Torbugesic, Zoetis, Sandton, South Africa).…”

“…Significant blood loss and hypothermia were evident during the surgical procedure, which lasted 2 h. The following day a peripheral venous blood sample was obtained for haematological analysis, which indicated a haematocrit of 23%. There are no published reference ranges for haematocrit values in the steenbok, although the normal haematocrit of the springbok ( Antidorcas marsupialis ), a larger antelope, has been recorded as 48% (Pospísil et al 1984 ; Vahala & Kase 1993 ). This antelope was therefore anaemic.…”

The steenbok (Raphicerus campestris) is a small antelope of the family Bovidae native to the African continent. Urolithiasis, the formation of urinary calculi in the urinary tract, can be caused by a variety of factors such as diet, dehydration, infection and anatomical predisposition. Urolithiasis, with uroliths identified as magnesium calcium phosphate carbonate in composition, was diagnosed in a hand-reared 5-month-old steenbok. Perineal urethrostomy was performed as a component of the broad treatment regime that included fluid therapy, antibiotic and anti-inflammatory treatment. However, the animal died 4 days later as a result of systemic hypoxia and energy depletion because of stress and cachexia. The challenges of post-surgical treatment, the importance of positive energy balance in small ruminants under stressful circumstances, as well as the role of diet of hand-reared antelope in predisposition to urolith formation are highlighted.

“…Depending on their exposure to handling, they might still get stressed while handling for health inspection, management, and research purposes. Moreover, few published studies have focused on the blood biochemical of common eland in the wild and captivity thus far, with few reference values available (Pospisil et al 1984 ; Vahala et al 1989 ). In addition, these studies utilised different immobilisation methods, leading to discrepancies.…”

Large herbivores are subject to handling and social stress in captivity. These may affect blood biochemical values, which motivated this research. Twelve healthy common eland (Taurotragus oryx) were monitored for 12 months. The animals were handled monthly, and blood samples were collected. Samples from every second month were analysed for 14 blood biochemical parameters. Temperament throughout the handling, as the summation of various behavioural responses, was calculated as a proxy of the stress generated during handling. Social behaviour was recorded each month, and the agonistic interactions were used to calculate the social rank, which was considered a proxy of social stress. Generalised Linear Mixed Models were designed to test the effects of temperament and social rank on the blood biochemical parameters while keeping sex, age, body condition, and body weight as covariates. The results show that the temperament during handling influences blood levels of albumin, alkaline phosphate, blood urea nitrogen, glucose, total bilirubin, and total protein; however, social rank has little influence, affecting just albumin. The ranges observed in the values of these biochemical parameters were still within their reference intervals, implying the absence of pathology or physiological problems during the study. The results suggest that blood biochemical values of physically restrained common eland should be carefully interpreted, even in animals already habituated to routine handling. On the contrary, social rank has low effects on the blood biochemical parameters.
