The limited number and weak reactivity of linear peptide epitopes observed with human and rabbit sera, possibly due to a lack of the methylated amino acids which are present in rickettsia-derived SPA, suggest that the present approach will not provide [ncbi.nlm.nih.gov]

Hence, it must be presumed that people infected with the human body louse are present in Italy. [unboundmedicine.com]

Cough is frequent, and pneumonia may also be present. Mental status changes and clouding, from which the disease gets its name-typhus is the Greek word for cloud-portend a poor prognosis. [centerforhealthsecurity.org]

Genes involved in transcription elongation and termination, nusA, nusB, nusG, greA and rho, are also present. [nature.com]

• Disability

  R. prowazekii infection seldom disables the host machinery completely. The host mechanisms to contain Rickettsia prowazekii are like other rickettsial infections. [ncbi.nlm.nih.gov]

• Hyponatremia

  In response to hypovolemia, secretion of antidiuretic hormone causes hyponatremia. Increased vascular permeability in the pulmonary circulation causes noncardiogenic pulmonary edema. Thus, a picture of severe multi-organ system failure unfolds. [ncbi.nlm.nih.gov]

• Complement Fixing Antibody

  The titres of complement-fixing antibodies in the sera of patients with Brill's disease with the antigen of R. mooseri were lower than the titres with the homologous antigen within the range of 1-2 twofold dilutions of the serum. [ncbi.nlm.nih.gov]

Treatment / Management Primary treatment of epidemic typhus is doxycycline 100 mg by mouth twice daily until the patient improves and has been afebrile for 24 to 48 hours. The total duration of treatment is typically between seven and ten days. [ncbi.nlm.nih.gov]

Treatment with tetracycline antibiotics is usually successful.[citation needed] References[edit] ^ a b Kurland, Charles G.; Andersson, Siv G. E.; Zomorodipour, Alireza; Andersson, Jan O.; Sicheritz-Pontén, Thomas; Alsmark, U. [en.wikipedia.org]

Treatment Doxycycline or chloramphenicol [pathwaymedicine.org]

Prophylactic treatment with doxycycline can be used in exposed individuals. A vaccine is not currently available, though many have been tested in the past without much reduction in incidence of disease. [centerforhealthsecurity.org]

Your healthcare provider may start treatment before results are available. Treatment Epidemic typhus should be treated with the antibiotic doxycycline. Doxycycline can be used in persons of any age. [cdc.gov]

Abstract Rickettsia prowazekii, the etiologic agent for epidemic typhus, and Borrelia recurrentis, the etiologic agent of relapsing fever, both utilize the same vector, the human body louse (Pediculus humanus), to transmit human disease. [ncbi.nlm.nih.gov]

Abstract Rickettsia prowazekii, the etiologic agent of epidemic typhus, is a potential biological threat agent. Lysine methylation of OmpB (outer membrane protein) of Rickettsia correlates with the bacterial virulence. [fasebj.org]

History of epidemiological exposure is very important for diagnosis. The incubation period is one to two weeks, with most infections becoming evident after ten to fourteen days. [ncbi.nlm.nih.gov]

The importance for human epidemiology is expected to be limited. Late relapse of epidemic typhus (Brill–Zinsser disease) might be the source of a re-emerging outbreak. [ecdc.europa.eu]

Natural Modes of Infection The epidemiology of rickettsial infections reflects the prevalence of rickettsiae in the vector population and the interactions of arthropod vectors with humans. [ehs.unc.edu]

The infection is also thought to have thwarted Napoleon's invasion of Russia by creating a burden of disease among the troops so high as to prevent them from mounting a successful campaign. [centerforhealthsecurity.org]
