1. Anthrax
Anthrax is an infection by the gram-positive spore-forming aerobic rod-shaped bacterium, Bacillus anthracis. It usually affects sheep, cattle, horses, goats, and swine. It may infect humans, causing meningitis and pneumonia with a high rate of death.

2. Kernig's sign
Kernig's sign is a clinical sign which is present in meningitis . The subject lies down on his or her back and a thigh is flexed to form a right angle with the trunk (i.e. perpendicular to the plane the subject is lying). The examiner then attempts to extend the leg. A positive Kernig's sign is present if complete extension of the leg is not possible because of limitation by pain.

3. Leptospirosis (spirochetal jaundice, Weil's disease, canicola fever)
Any disease caused by a member of the bacterial genus Leptospira , which chiefly afflicts a number of livestock and other domestic animals but can also affect humans. The disease is spread by the urine of infected people and animals. When found in humans, the disease is also called canicola fever, mud fever, swamp fever, hemorrhagic jaundice, infectious jaundice, spirochetal jaundice, swineherd's disease, and Weil's disease, and tends to infect people who handle animals or who come into contact with animal urine (either directly or through contaminated soil and water) or infected animal tissue. Symptoms often include fever, headache, chills, and muscle pain, but can also include jaundice , bleeding and/or hemorrhaging in or below the skin, rash, meningitis , and renal insufficiency (kidney failure).

4. Meningitis
A general term for any illness that involves inflammation of the meninges . It is frequently caused by the bacterium Neisseria meningitidis. Such meningococcal meningitis is an acute, infectious disease that causes symptoms such as skin rash, headache, congestion, neck muscle rigidity, light sensitivity, nausea and convulsions. The bacterium Listeria monocytogenes, which is found in human feces, can also cause the disease. A much less common cause of meningitis is advanced-stage syphilis. The term can also refer to the symptom of having inflamed meninges.

5. Mumps
Mumps is an infection of the paramyxovirus. Clinically, it is characterized by inflammation of the salivary glands, orchitis , and sometimes aseptic meningitis , pancreatitis , and oophoritis .

6. Neurosyphilis
This is the infection of the central nervous system by the bacteria Treponema pallidum. Four clinical types are often identified: * asymptomatic neurosyphilis: no clinical signs or symptoms, but cerebrospinal fluid examination is positive for the infection. * interstitial neurosyphilis: syphilitic leptomeningitis, vascular neurosyphilis, cerebrospinal fluid tests positive for the infection, symptomatic for meningitis, or CVA. * tabes dorsalis: chronic progressive degeneration of the posterior columns of the spinal cord. * general paresis: infection of the cerebral cortex: personality changes, memory loss, and loss of concentration are common.

7. Syphilis (Treponema pallidum, T. pallidum)
Syphilis is a sexually-transmitted disease caused by the spirochete (elongated, spiral-shaped bacterium) Treponema pallidum. This serious disease can lead to insanity or death. The symptoms can resemble those of other diseases, which can make diagnosis difficult. Syphilis is characterized by four stages: Primary Stage * occurs 10-100 days after infection. * is characterized by the appearance of one or more chancres (a red, bloodless, painless ulcer less than 1 cm in diameter). These appear on the genitalia (and can be inside the vagina in women and can go unnoticed). A chancre may appear elsewhere on the body; if so, it can become inflamed and/or produce pus. A chancre lasts 3-6 weeks and heals without treament, leaving a small scar. * causes swollen lymph nodes near the site of a chancre. * is contagious. Secondary Stage * characterized by rashlike skin lesions that can cover part or all of the body. The lesions are painless (unless they get a secondary infection) and appears 1-6 months after the appearance of the chancre. They can resemble warts, pustules, or ulcers. Left untreated, they heal in 2-12 weeks without scarring. * also causes fever, sore throat, weakness, weight loss, swelling of the lymph nodes, and loss of the eyelashes and/or part of the eyebrows. * can turn into meningovascular syphilis, a secondary form characterized by inflammation of the covering of the brain and spinal cord (aseptic meningitis) and/or changes in the vascular structure of the brain. * is contagious. Latent Syphilis ("Hidden Stage") * the infected person appears to have recovered and is usually symptom-free. * lasts from 1-46 years (2-20 years is most common) * can be interrupted by relapses to secondary stage syphilis; 25% of infectees have relapses, usually in the 1st year of latency (but relapses can occur up to 4 years after latency starts). * is not contact infectious, except during a relapse; however, children born to latent infectees may still be congenitally infected. Tertiary Syphilis ("Late Stage") * may occur as early as one year after infection or anytime thereafter * eventually appears in 33% of untreated sufferers * causes widespread lesions of the skin, bones, and internal organs. * causes severe neurologic and cardiovascular problems, leading to possible insanity, blindness, and death. A person who has been infected with syphilis does not acquire immunity to it. If a woman with syphilis gets pregnant, her child may be born with congenital syphilis. 40% of infected fetuses die before birth; newborns suffer from secondary-stage syphilis and enter the latent stage if they survive their first year. Syphilis can be cured with antibiotics; using a condom during sex can reduce the risk of transmission.
