Acquired immunity in experimental murine aspergillosis is mediated by macrophages.

A number of studies have substantiated the pivotal role of innate defense mechanisms in protection against invasive aspergillosis. However, experiments demonstrating increased resistance to lethal intravenous (i.v.

Adherence of Streptococcus suis capsular type 2 to porcine lung sections.

The present study was undertaken to evaluate the ability of 33 Streptococcus suis capsular type 2 isolates to adhere to frozen sections of porcine lung. Twenty isolates originated from diseased pigs and 13 from the nasal cavities of clinically healthy pigs. All isolates from diseased animals adhered to lung sections; isolates from pneumonia adhered, in general, in greater numbers than isolates from meningitis.
