Observations and perceptions of veterinarians and farmers on heartwater distribution, occurrence and associated factors in South Africa

Background: There is currently no scientific evidence regarding the current climatic or other epidemiological factors that could influence the occurrence of heartwater in South Africa. Objectives: The objective was to determine whether climatic changes or other epidemiological factors influence the occurrence of heartwater in South Africa. Method: A survey was conducted to scrutinise these factors using both veterinarians and farmers working in known areas in which heartwater had previously been confirmed to establish the value of each of these factors.

A survey of wildlife populations at Wassaniya forest reserve in Sokoto State, Nigeria

A survey of wildlife populations was conducted between May to September 2009, at Wassaniya forest reserve between Tangaza and Gudu Local Government Areas of Sokoto State, Nigeria. The study area was purposively divided into four main plots based on vegetation density and human interference. Three sample plots each measuring 0.5 ha were randomly selected and demarcated in each main plot for data collection and as replicates. Data was collected using both direct and indirect methods. The direct method was by

The impact of nutrition on the development of urolithiasis in captive giraffes and meat goats

Obstructive urolithiasis is a documented problem in domestic ruminants, such as the meat goat, and also in captive giraffe. A survey of the health history, feeding practices, and dietary contents in captive giraffes in North America was conducted to examine the possible connection between diet and the development of urolithiasis. Samples of urine, serum and feed were collected and analyzed for basic panels and mineral content. There appeared to be a positive correlation between diet and physiologic phosphorus levels in

Internal parasites of giraffes (Giraffa camelopardalis angolensis) from Etosha National Park, Namibia

During three seasonal periods, parasitological samples were collected from six giraffes (Giraffa camelopardalis angolensis) in the Etosha National Park, Namibia. The helminths recovered included Parabronema skrjabini, Skrjabinema spp., Haemonchus mitchelli and Echinococcus sp. larvae; Cytauxzoon sp. was the only hematozoan found. The low mean abundances of all helminths which ranged from 18 to 531 may be attributed to the low rainfall of this region or because the giraffe is not a preferred host for these species of helminths.

Abundance and distribution of mammals in Katavi National Park, Tanzania

Ground transects were used to determine densities of 24 larger mammals in Katavi National Park. The Park consists of miombo woodland habitat and two seasonal lakes. Mammalian biomass was extremely high due primarily to large numbers of buffalo. The highest mammal densities were found around Lake Chada to the southeast of the Park. Contrary to earlier reports, species’ densities did not differ significantly between dry, wet and intermediate seasons, suggesting that, aside from elephant and warthog, mammals did not enter
