The symptoms in anthrax depend on the type of infection and can take anywhere from 1 day to more than 2 months to appear. All types of anthrax have the potential, if untreated, to spread throughout the body and cause severe illness and even death. [24] Four forms of human anthrax disease are recognized based on their portal of entry.
Anthrax is a disease caused by Bacillus anthracis, a spore-forming, Gram positive, rod-shaped bacterium (Fig. 1).The lethality of the disease is caused by the bacterium's two principal virulence factors: (i) the polyglutamic acid capsule, which is anti-phagocytic, and (ii) the tripartite protein toxin, called anthrax toxin.
Damage caused by the anthrax spores and bacilli to the central chest cavity can cause chest pain and difficulty breathing. Once in the lymph nodes, the spores germinate into active bacilli that multiply and eventually burst the macrophages, releasing many more bacilli into the bloodstream to be transferred to the entire body.
DNA vaccine approaches for dental cavities have had a history of success in animal models. Dental cavity vaccines directed to key components of S. mutans colonization and enhanced by safe and effective adjuvants and optimal delivery vehicles, are likely to be forthcoming. Some believe that the rational target for developing an anti-caries ...
Dental cavity, also known as tooth decay, [a] is the breakdown of teeth due to acids produced by bacteria. [6] The resulting cavities may be a number of different colors, from yellow to black. [ 1 ] Symptoms may include pain and difficulty eating.
Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. [ 1 ] [ 2 ] The microbe was first described by James Kilian Clarke in 1924.
If a tooth is infected by dental caries there are two main treatment options. Teeth with dental caries get extracted in most veterinary clinics. A second option is specialized vets that can save teeth from an extraction. If there remains enough enamel the tooth can be repaired. In the case of decay to the tooth pulp, a root canal treatment is ...
All received treatment and officials reported the situation as under control by August 1998.
