    A breeding pair of fleas can lay more than eggs in a month. Their offspring can remain dormant for two years before they become mature fleas. Fleas carry and transmit diseases such as tapeworm, rickettsiae, human plague (rare) and can cause allergic reactions from antigens in their saliva. In large numbers, they can suck enough blood to.

Aug 31,  · Rickettsioses are diseases caused by members of the typhus group and spotted fever group of Rickettsia. Pathogenic Rickettsia are typically transmitted to humans by arthropods (insects and ticks). This project seeks to examine the interplay between Rickettsia felis and the vector flea, to better understand the ecology of flea-borne spotted fever.

Changing patterns in man’s ecosystems caused by man have led among other things to a spreading of arthropod-related zoonoses in impoverished as well as in industrial countries.

For the flea, its biology makes it a very efficacious vector of many pathogens. The reasons that the cat flea is such an extremely successful and ubiquitous parasite are the wide range of possible hosts and its status. Scott and Duncan's Use of the Reed–Frost Model in Historical Plague Research.

3 Therefore, it is timely to provide a concise review of flea biology, synanthropic fleas, and flea-borne diseases, presenting updated Cited by: This article addresses the recent use of mathematical epidemiological SIR or SEIR models in plague research.

This use of S(E)IR models is highly problematic, but the problems are not presented and considered. Serious problems show in that such models are used to “prove” that historical plague was a (1) Filoviridae disease and (2) a bacterial disease caused by Yersinia pestis which Author: Ole J.
