Abstract Vectors of emerging infectious diseases have expanded their distributional ranges in recent decades due to increased global travel, trade connectivity and climate change. Transboundary range shifts, arising from the continuous movement of humans and livestock across borders, are of particular disease control concern.

Human Pathogens in Body and Head Lice
Using polymerase chain reaction and sequencing, we investigated the prevalence of Rickettsia prowazekii, Bartonella quintana, and Borrelia recurrentis in 841 body lice collected from various countries. We detected R.

DNA gyrase is an essential topoisomerase in bacteria that plays critical roles in the management of nucleoid structure, DNA replication, transcription and recombination. It is also a major drug target. The gyrA and gyrB genes that encode the two subunits of DNA gyrase are located at widely separated sites on the chromosome of Salmonella and other ...

Construction of Immune-Chromatographic Indicator Elements for Burnet Rickettsia Detection
mc/ml, and the elapsed time – 20 minutes. The IE is specific to other members of the family Ricketsiaceae, for instance to R. prowazekii , to antigen complexes of R. prowazekii and R. sibirika , as well as to vaccinia virus (L-IVP strain).

Potassium permeability of Rickettsia prowazekii [PDF]
The potassium permeability of Rickettsia prowazekii was characterized by chemical measurement of the intracellular sodium and potassium pools and isotopic flux measurements with 86Rb+ as a tracer. R. prowazekii, in contrast to Escherichia coli, did not maintain a high potassium-to-sodium ratio in their cytoplasm except when the potassium-to-sodium ...

Correlation property of length sequences based on global structure of complete genome [PDF]
This paper considers three kinds of length sequences of the complete genome. Detrended fluctuation analysis, spectral analysis, and the mean distance spanned within time $L$ are used to discuss the correlation property of these sequences.
