Journal ArticleDOI
The Role of Cell-Mediated Immunity in Bacterial Infections
TL;DR: A study of Macrophage-Dependent Resistance in the Absence of Specific Immune Responses and the Role of Polymorphonuclear Leukocytes shows the importance of knowing the carrier and removal status of canine coronavirus.
Journal ArticleDOI
Involvement of M cells in the bacterial invasion of Peyer's patches: a common mechanism shared by Yersinia enterocolitica and other enteroinvasive bacteria.
TL;DR: In this article, transmission and scanning electron microscopy have shown that only a small fraction of bacteria present in the lumen adhere to the follicle-associated murine epithelium with no discernible preference for either M or absorptive cells.
Journal ArticleDOI
Immunohistochemical and electron microscopic study of interaction of Yersinia enterocolitica serotype O8 with intestinal mucosa during experimental enteritis.

TL;DR: The integrity of the basement membrane is likely to play a role in determining the route of entry and limit of spread of Y. enterocolitica infection.
Journal ArticleDOI
Comparison of Broth Microdilution, E Test, and Agar Dilution Methods for Antibiotic Susceptibility Testing of Campylobacter jejuni and Campylobacter coli
TL;DR: The broth microdilution method appears to be an easy and reliable method for determination of the MICs of antibiotics for C. jejuni and C. coli, and it may offer an interesting alternative to MIC determination by the agar dilution technique or the E test.
Journal ArticleDOI
T-cell subsets in delayed-type hypersensitivity, protection, and granuloma formation in primary and secondary Listeria infection in mice: superior role of Lyt-2+ cells in acquired immunity.
TL;DR: In murine listeriosis, DTH and acquired immunity to reinfection are dissociable phenomena, and the roles of the different T-cell subsets in granuloma formation warrant further investigation.
