Post-transfusion cytomegaloviremia and persistence of cytomegalovirus in blood.

Cytomegaloviremia was documented in seven patients. Three patients were renal transplant recipients and two were liver transplant recipients. One was a postcardiac surgery patient, and one had acute myelogenous leukemia. The transplant patients had received only banked blood or fresh frozen plasma and developed evidence of infection about 1 month after surgery. Illness varied from no apparent signs to fever alone, fever and a morbilliform rash, hepatitis and an infectious mononucleosis syndrome. The virus was isolated from the blood erythrocyte layer, the leukocyte layer, and the plasma and serum, in that order of frequency. In vitro studies demonstrated persistence of inoculated cytomegalovirus in the presence of erythrocytes (and tissue culture media) for up to 21 days. In whole blood under banking conditions, inoculated virus was recovered after 28 days and, in fresh frozen plasma, after 97 days.

Previously uncharacterized Mycoplasma isolates from an investigation of canine pneumonia.

Mycoplasmas recovered from the respiratory tract and genitourinary system of dogs, with and without respiratory infection, have been characterized by biological and immunological methods. Some of the isolates were indentified as being similar to the three species of canine mycoplasmas described earlier under the designation Mycoplasma spumans, M. canis, and M. maculosum. Other mycoplasmas placed in three groups (A, C, and D) were found to be clearly distinct from the three classified species. Group A strains fermented glucose but not mannose and were serologically distinct from other canine mycoplasmas recovered in this study. These strains were subsequently found to be biologically and serologically related to a previously reported, but unclassified, canine mycoplasma. Group D strains differed in some biological properties but were serologically related. These were found to be nonfermenting mycoplasmas representing isolations from the throat and bladder of dogs. They were serologically distinct from other canine mycoplasmas and were apparently unrelated to other known mycoplasma serotypes. Group C mycoplasmas were recovered only from the lungs of dogs. Within the group, they differ in some immunological properties but appear to be serologically distinct from other canine strains. They can also be separated from other dog strains in their ability to ferment glucose and mannose. Group B strains were found to have biological properties similar to M. canis strains but seemed to be only partially related to this serotype when examined in several serological techniques. It is suggested that these strains might represent antigenic variants of M. canis.
