Typhus, murine
An acute infectious disease with fever, headache, and rash, all quite similar to, but milder than, epidemic typhus, caused by a related microorganism, Rickettsia typhi (mooseri), transmitted to humans by rat fleas (Xenopsylla cheopis). The animal reservoir includes rats, mice and other rodents. Murine typhus occurs sporadically worldwide but is more prevalent in congested rat-infested urban areas. Also known as endemic typhus, rat-flea typhus, and urban typhus of Malaya.

Also known as Rocky Mountain spotted fever, an acute febrile (feverish) disease initially recognized in the Rocky Mountain states, caused by Rickettsia rickettsii transmitted by hard-shelled (ixodid) ticks. Occurs only in the Western Hemisphere. In the USA it is most common in the southeastern and south-central states, not in the Rocky Mountains. Anyone frequenting tick-infested […]

- Tyrosinemia
A genetic disorder involving the metabolism of the amino acid tyrosine characterized by abnormally high levels of tyrosine in blood (hypertyrosinemia) and urine (tyrosinuria). There are several different forms of tyrosinemia. The classic form, tyrosinemia type I, is due to deficiency of an enzyme called fumarylacetoacetic hydrolase, the last enzyme in the tyrosine pathway. Although […]
- Tyrosinemia type I
A metabolic genetic disease characterized by abnormally high levels of amino acid tyrosine in blood (hypertyrosinemia) and urine (tyrosinuria) due to deficiency of an enzyme called fumarylacetoacetic hydrolase, the last enzyme in the tyrosine pathway. Tyrosinemia type I is inherited as an autosomal recessive disorder. The disease causes cirrhosis of the liver before 6 months […]
