PYREXIA AFTER HEART SURGERY DUE TO VIRUS INFECTION TRANSMITTED BY BLOOD TRANSFUSION

Resistant pathogens, fungi, and viruses

Although originally described in Staphylococcus aureus, resistance among bacteria has now become a race to determine which classes of bacteria will become more resistant. Availability of antibacterial agents has allowed the development of entirely new diseases caused by nonbacterial pathogens, related largely to fungi that are inherently resistant to antibacterials. This article presents the growing body of knowledge of the herpes family of viruses, and their occurrence and consequences in patients with concomitant surgical disease or critical illness. The focus is on previously immunocompetent patients, as the impact of herpes viruses in immunosuppressed patients has received thorough coverage elsewhere.

Seronegative glandular fever

Seven sporadic cases of ;seronegative glandular fever' have been examined in detail; five of the patients were adults aged more than 30, two were children. None showed evidence of ;incomplete' or heat-labile sheep cell agglutinins, but in three very weak, though otherwise typical, glandular fever agglutinins were detected. Three of the other four showed evidence of certain infections, but these infections probably accounted for no more than a part of each illness. It is suggested that some, and possibly most, sporadic cases of seronegative glandular fever are of the same disease as seropositive cases, the patients' ages influencing the serological response. Certain conditions of known aetiology may, however, be clinically and haematologically indistinguishable from seronegative glandular fever.
