In March 2002, typhus fever was diagnosed in two patients residing in West Virginia and Georgia. Both patients were hospitalized with severe febrile illnesses, and both had been recently exposed to or had physical contact with flying squirrels or flying squirrel nests. Laboratory results indicated Rickettsia prowazekii infection. T yphus fever from(More)
Bordetella bronchiseptica is a pleomorphic gram-negative coccobacillus that commonly causes respiratory tract infections in dogs. We identified nine human immunodeficiency virus (HIV)-infected persons with culture-confirmed B. bronchiseptica infections (eight respiratory tract and one disseminated infection). The respiratory illnesses ranged in severity(More)
A communitywide outbreak of gastrointestinal illness due to Giardia lamblia infection occurred in the city of Berlin, New Hampshire, during April and May 1977. The clinical, epidemiologic, and laboratory aspects of this outbreak are described here. In 213 predominantly symptomatic cases of G. lamblia infection diagnosed at a local hospital laboratory in a(More)
We present the third installment of the Yale/San Juan Southern Proper Motion Catalog, SPM3. Absolute proper motions, positions, and photographic B,V photometry are given for roughly 10.7 million objects, primarily stars, down to a magnitude of V=17.5. The Catalog covers an irregular area of 3700 square degrees, between the declinations of-20 • and-45 • ,(More)
In the period 1960 to 1979, 177 cases of tularemia occurred in residents of Georgia. A tick bite was the implicated source of exposure in eight cases (4.5%), whereas 91 cases (51.4%) were associated with direct contact with infected rabbits. In Georgia and other southeastern states, the epidemiology of human tularemia infection primarily involves rabbits.(More)
Experimental measurements of laminar fl ame speed for premixed methane-air fl ames were carried out for different equivalence ratios at subatmospheric conditions, 852 mbar and 298 K. The fl ames were obtained using a rectangular port burner with a water cooler system necessary to maintain the temperature of the mixture constant. An ICCD camera was used to(More)
A high incidence of diarrhea was reported in a group of approximately 1,400 Americans who traveled to the Portuguese island of Madeira in October 1976. A mail questionnaire survey revealed that 39% of the responding 859 travelers experienced diarrhea; in 42% of these diarrhea lasted for longer than 1 week. The most frequent accompanying symptoms were(More)
Minimum inhibitory concentrations (MIC) of pirbenicillin against 135 clinical isolates of Pseudomonas aeruginosa were one-fourth of those required for carbenicillin but two times higher than those for BL-P1654. Increasing the inoculum size produced an adverse effect on the bactericidal activity for all three antibiotics. This was more apparent for(More)
