Sera from 19 wild caught vultures in northern Namibia and 15 (12 wild caught and three captive bred but with minimal histories) in North West Province, South Africa, were examined by an enzyme-linked immunosorbent assay (ELISA) for antibodies to the Bacillus anthracis toxin protective antigen (PA). As assessed from the baseline established with a control group of ten captive reared vultures with well-documented histories, elevated titres were found in 12 of the 19 (63%) wild caught Namibian… 
Serological evidence for human exposure to Bacillus cereus biovar anthracis in the villages around Taï National Park, Côte d’Ivoire
TLDR
A retrospective seroprevalence analysis with sera from 1,386 study volunteers confirmed antibodies against the protective antigen PA, which is synthesized by both Bcbva and classic B. anthracis, and against the recently described antigen pXO2-60, a 35-kDa protein only produced by BCBva.
Frequent and seasonally variable sublethal anthrax infections are accompanied by short-lived immunity in an endemic system.
TLDR
The results indicate that zebra in ENP often survive sublethal anthrax infections, encounter most B. anthracis in the wet season and can partially booster their immunity to B. anthracis, rather than being solely a lethal disease, anthrax often occurs as a sublethal infection in some susceptible hosts.
Naturally Acquired Anthrax Antibodies in a Cheetah (Acinonyx jubatus) in Botswana
TLDR
The finding of one antibody-positive animal amongst at least 16 potentially exposed individuals is consistent with existing reports that it is uncommon for cheetahs to develop natural immunity to anthrax.
Low antibody prevalence against Bacillus cereus biovar anthracis in Taï National Park, Côte d'Ivoire, indicates high rate of lethal infections in wildlife
TLDR
The results of a serological study of anthrax in five wildlife species known to succumb to Bcbva indicate high virulence of this disease across these different mammalian species.
ANTE- AND POSTMORTEM DIAGNOSTIC TECHNIQUES FOR ANTHRAX: RETHINKING PATHOGEN EXPOSURE AND THE GEOGRAPHIC EXTENT OF THE DISEASE IN WILDLIFE
TLDR
The current understanding of the serologic response to anthrax among wildlife hosts and serologic diagnostic assays used to augment traditional postmortem anthrax surveillance strategies are reviewed and recommendations for the use of serology and sentinel species surveillance approaches in anthrax research and management are provided.
Production and characterization of the monoclonal antibodies to Bacillus anthracis protective antigen
TLDR
This work obtained a representative panel of 20 monoclonal antibodies to the anthrax protective antigen, a key component of the pathogenic exotoxin, and a sandwich ELISA for quantification of the protective antigen using these antibodies was developed.
Epidemiology of anthrax outbreaks in wood bison (Bison bison athabascae) of the Mackenzie bison population
Wood bison (Bison bison athabascae) conservation in Northern Canada is negatively affected by diseases that kill these animals, such as anthrax caused by the bacterium Bacillus anthracis. Although
One Health approach for elimination of human anthrax in a tribal district of Odisha: Study protocol
TLDR
This protocol aims to describe the implementation and evaluation of the ‘One Health’ intervention model based on the principles of Theory of Change (ToC) to eliminate human anthrax from a tribal district in Odisha, India.
The ecology of Bacillus anthracis.
The global distribution of anthrax is largely determined by soils with high calcium levels and a pH above 6.1, which foster spore survival. It is speculated that the spore exosporium probably plays a
Expression and refolding of the protective antigen of Bacillus anthracis: A model for high-throughput screening of antigenic recombinant protein refolding.
TLDR
The high-throughput approach described in this study that enabled overproduction, purification and refolding of PA in a simple and straightforward manner, can be potentially useful for the rapid screening of adequate refolding conditions for other overexpressed antigenic proteins.

Serology and anthrax in humans, livestock and Etosha National Park wildlife.
TLDR
Results are presented from a number of epidemiological studies using enzyme immunoassays (EIA) based on the purified anthrax toxin antigens, protective antigen, lethal factor and oedema factor to show that EIA using protective antigen can be a useful diagnostic aid and will detect subclinical infections in appropriate circumstances.
Vaccine-induced protection against anthrax in cheetah (Acinonyx jubatus) and black rhinoceros (Diceros bicornis).
TLDR
The conclusions were that vaccination of cheetah with the standard animal anthrax vaccine causes no observable ill effect in the animals and does appear to confer protective immunity, and Vaccination of rhino also appears to be justified from the limited data obtained.
ANTIBODIES TO Clostridium botulinum TOXINS IN FREE-LIVING BIRDS AND MAMMALS
Naturally-occuring antibodies against Clostridium botulinum toxins were found in Cathartes aura (turkey vultures), Canis latrans (coyotes) and Corvus brachyrhynchos (crows) by the passive
Ecology and epidemiology of anthrax in the Etosha National Park, Namibia.
TLDR
Age and sex analyses indicate that, except for zebra, proportionally greater numbers of adult males die of anthrax among the species predominantly affected; however, zebra carcases are difficult to sex.
Anthrax and wildlife.
TLDR
Research is required into the genotypic grouping of anthrax isolates, improved field diagnostic techniques, and oral vaccines, as well as to provide a better understanding of spore survival in soil and the ecology of the disease under natural conditions.
Development of antibodies to protective antigen and lethal factor components of anthrax toxin in humans and guinea pigs and their relevance to protective immunity
TLDR
The ELISA system was shown to be capable of detecting anti-PA and anti-LF antibodies in the sera of individuals with histories of clinical anthrax, and was markedly superior in terms of reproducibility, reliability, specificity, and simplicity in performance and stability of the bound antigen.
Massive outbreak of anthrax in wildlife in the Malilangwe Wildlife Reserve, Zimbabwe
TLDR
A massive outbreak of anthrax in the wildlife of the Malilangwe Wildlife Reserve in Zimbabwe between August and November 2004 resulted in the death of almost all the reserve's estimated 500 kudu (Tragelaphus strepsiceros) and Buffalo (Syncerus caffer) were badly affected.
Further progress in understanding anthrax in the Etosha National Park
TLDR
Culture and serological results obtained during a 5-week field study on anthrax in the Etosha National Park are presented, finding vegetative forms of B. anthracis inoculated into water samples declined rapidly in number and spore forms showed no inclination to germinate.
DIVERSITY IN BODY SIZE AND FEEDING MORPHOLOGY WITHIN PAST AND PRESENT VULTURE ASSEMBLAGES
TLDR
Comparisons between the fossil and extant New World vultures indicate that more specialized species were prone to extinction and that there has been a reduction in body size since the Pleistocene.
