Bat-eared fox behavioural ecology and the incidence of rabies in the Serengeti National Park

This paper provides a brief introduction into some aspects of bat-eared fox biology and social organization that is important to understanding rabies transmission and disease management in susceptible wildlife species (Macdonald 1980; 1993). A detailed description of the effects of two rabies outbreaks on a population of known individuals in the Serengeti National Park is given. Inter- and intrasexual differences in adult mortality rates are reported and discussed.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Bait formulation and distribution for oral rabies vaccination of domestic dogs : an overview

Current efforts to develop oral rabies vaccine baits for domestic dogs are reviewed and new materials (bait matrices, additives, vaccine containers, vaccine modification) for improving bait acceptance and vaccine delivery are suggested. Methods that have been used to evaluate the food or bait preferences of confined and free-ranging animals are summarized, as are the guidelines for bait distribution compiled by the World Health Organization.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Monoclonal antibody studies on rabies-related viruses

Rabies and rabies-related viruses are divided into four serotypes, although it has been suggested that the inclusion of European bat lyssaviruses results in six genotypes. Sixty-four rabies-related viruses were tested against a panel of 36 anti-nucleocapsid monoclonal antibodies prepared from the immunization of Balb/ʗ mice with five prototypic rabies-related viruses. Reaction patterns obtained confirmed the original distinction between serotype 1-4 viruses and revealed multiple variants of Lagos bat and Mokola viruses. In addition, two biotypes of European bat lyssavirus were identified and a clear distinction was shown between these biotypes and Duvenhage virus of Africa. The origins and importance of the rabies-related viruses are discussed.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Canine rabies

Dog rabies is still epizootic in most countries of Africa, Asia and South America and in these countries dogs are responsible for most human deaths from the disease. The incubation period in dogs may vary from one week to several months and may be influenced by the site of infection and the virus dose and strain. Diagnosis by clinical signs alone is inadequate since many rabid dogs develop dumb rabies which can easily be overlooked and others die without showing signs of rabies. Rabies virus may be excreted in the saliva before clinical signs appear and may lead to infection of an unsuspecting and untreated bite victim. Dogs may recover from clinical rabies and may then intermittently excrete virus in the saliva. Prevention of human rabies depends on the control of canine rabies which can only be achieved by mass-immunization and control of stray dog populations.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

The bat-eared fox : a prime candidate for rabies vector?

Bat-eared foxes, Otocyon megalotis , are small (3-5 kg) , primarily insectivorous carnivores widespread in the more arid areas of southern and East Africa. For many months of the year they live in nuclear family groups, members of which frequently indulge in affiliative behaviour such as play, allogrooming, and huddling. Physical contact between individuals in any particular group is thus common. In addition, groups are non-territorial and intermingle freely at times when exploiting food-rich patches of clumped prey, e.g. individuals foraging for harvester termites, Hodotermes mossambicus.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Rabies and wildlife : a conservation problem?

Understanding the behavioural ecology of wild mammals in rabies epizootics is a prerequisite to scientifically sound management of the disease. The principal vectors of wildlife rabies in a region tend to be abundant representatives of the Carnivora. Although the population dynamics of these species may be radically affected by rabies, and by attempts to control it, they are generally not threatened with widespread extinction as a result. However, the cases of the Blanford's fox, Vulpes cana, the Ethiopian wolf, Canis simensis, and the African wild dog, Lycaon pictus, illustrate how rabies and its control can pose grave conservation problems for rare carnivores. Disease monitoring is therefore an important element of recovery plans for rare species which are potential victims of rabies and other epizootic pathogens, and the benefits and disbenefits of prophylactic vaccination merit serious evaluationThe articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Biology of the black-backed jackal Canis mesomelas with reference to rabies

The black-backed jackal is represented in rabies records from southern Africa and is suspected of playing an important role in the disease in this region. The basic biology of the species suggests that it does have certain characteristics that could make it an ideal rabies vector. However, the enigmatically low incidence of rabies in undisturbed jackal populations suggests that more subtle processes may be involved. It is suggested that jackal society is arranged in the form of cryptic packs and that disruption of the hierachy through persecution may increase agonistic encounters and thence the incidence of rabies. Suggestions are made for the incorporation of the jackal in rabies control programmes without resorting to extermination.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Social systems and behaviour of the African wild dog Lycaon pictus and the spotted hyaena Crocuta crocuta with special reference to rabies

Differences in the social systems and behaviour of two potentially important hosts of rabies, the African wild dog and the spotted hyaena, may lead to differences in the epizootiology of the disease in the two species. Wild dogs are highly social animals in which pack members are in constant physical contact with each other, but in which inter-pack interactions are rare. Spotted hyaenas are more flexible in their social systems and behaviour. Clan members interact less frequently than do wild dogs, but inter-clan contact rates may be high in high density populations. Rabies transmission within wild dog packs should be rapid, but rare between packs. In spotted hyaenas rabies transmission between clan members may partially depend on the social status of the animals involved and between packs on the density of hyaenas in the area.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.
