Simplified maps of each site, showing the cover of macrophytes, were obtained monthly between April 1974 and April/June 1976, and(More)
In the United States, murine typhus (Rickettsia typhi) is endemic in southern California and South Texas. Evidence indicates the natural host/vector system is the opossum and cat flea, the most common flea on both cats and dogs, and speculation suggests that pet contact may pose a risk for R typhi exposure.

AIMS Quality assessment of therapeutic procedures is essential to insure a cost-effective health care system. Pacemaker implantation is a common procedure with more than 500,000 implantations world-wide per year, but the general complication rate is not well described. We studied procedure related complications for all implantations performed in an entire(More)
Murine typhus (Rickettsia typhi), endemic in southern California and South Texas, is maintained within a host-vector system consisting of the opossum and cat flea. In the early 1990s, a second rickettsial species, Rickettsia felis, was also found to be maintained within the opossum-cat flea system and is, in fact, found more commonly than R. typhi in the(More)
