High antibody titers in ruminants infected with Mycobacterium avium subsp. paratuberculosis correlates with disease progression. Effects of humoral responses during mycobacterial infection are not completely understood. This study suggests that activation status may be an important factor in determining macrophage ability to limit proliferation of opsonized(More)
tory effects of experimental hypercorticalism.3 The visual effects of ionizing radiation on the blood flow, small blood vessels, and endothelium of capillaries and venules in the hamster cheek pouch have been studied.4 As a basis for the correlation and interpretation of these observations with respect to changes in the usual hematologic values, we have(More)
The small venules of the hamster cheek pouch were rendered susceptible to hemorrhage by total body x-irradiation, cheek pouch x-irradiation and beta emanations from strontium-90 glass beads imbedded in the cheek pouch, as determined by negative pressure and moccasin venom tests. Petechiae were formed without vessel rupture and ceased without formation of(More)
Lysis and filtration of blood culture specimens were combined with impedance detection of bacterial growth to facilitate the diagnosis of bacteremia. A blood lysis-filtration technique (Zierdt et al., 1976) was coupled to a simple, inexpensive automated detection system. The practical and technical aspects of the impedance detection system are discussed.(More)

Tissue culture media used by skin and tissue banks to store tissue were tested, with and without antimicrobial mixtures, for their ability to inhibit the growth of bacteria during incubation at refrigerator temperatures. Reductions in bacterial load were found after incubation at 4 degrees C in both the basal tissue culture media with and without the(More)
A free-ranging Mexican gray wolf (Canis lupus baileyi) suffered intestinal rupture following ingestion of an insecticidal cattle ear tag. Subsequent organophosphate toxicosis as a cause of the rupture was speculated. Insecticidal ear tags could represent a poisoning risk in canids and other wildlife scavengers.
We report a search for the flavor-changing neutral current decay B → Xsl +l− using a 29.5 fb−1 data sample accumulated at the Υ(4S) resonance with Belle detector at the KEKB e+e− storage ring. We observe evidence for B → Kμ+μ− and report the preliminary branching fraction of B(B → Kμ+μ−) = (0.99 −0.32 +0.13 −0.15)× 10−6. We also set the following 90%(More)
