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]

• 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]

• Skin Eschar

  Rickettsial diseases are widely distributed throughout the world and are characterized by sudden onset of acute fever, skin eschars, headache, and, in cases of the fulminant disease, disseminated intravascular coagulation that leads to failure of the [jb.asm.org]

• 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]

• Gram-Positive Bacteria

  Pyruvate dehydrogenase (E1) consists of two subunits (α and β) in R. prowazekii, mitochondria and Gram-positive bacteria; the corresponding genes are clustered in the genome. [doi.org]

• 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]

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]

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]

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]

In fact, BZD presents with milder symptoms and is rarely fatal. [7][8] Pathophysiology The human body louse is only a vector and not a reservoir because infected lice die five to seven days after they become infected with R. prowazekii. [ncbi.nlm.nih.gov]
