Viremia and virus measurements of rabbit pox in CV-1 cells.

Rabbit pox virus (RPV) produced cytopathic effect (CPE) in five types of cells grown in tissue cultures. The CPE on CV-1 cells was characterized by cell fusion and lysis. The CV-1 line is a useful and sensitive cell culture for measuring concentrations of RPV in blood and tissues of infected rabbits. Viremia was detected between the 2nd and 4th days after parenteral infection. By the 6th and 7th days, the concentration of RPV in various tissues ranged from 10(5-3) to 10(8-5) TCID(50)/g. Cross-reactivity was demonstrated by the fluorescent-antibody technique between rabbit pox, vaccinia, and monkey pox viruses.

Characteristic features of neonatal sepsis due to Haemophilus influenzae.

The number of cases of neonatal Haemophilus influenzae sepsis reported in the literature has increased. The predominant serotypes (80%) involved in neonates appear to be non-type b whereas in older infants type b is responsible for the great majority of cases. It appears that most cases of neonatal H. influenzae sepsis begin before or at the time of delivery, as the disease is strongly associated with early postnatal onset (83%), prematurity (83%), and a variety of maternal complications (44%). The mortality rate is 55.5% overall but 90% among babies born at less than or equal to 30 weeks of gestation.

Human herpesvirus 6 infection.

Human herpesvirus 6 (HHV-6) was identified in 1986 and roseola infantum was the first disease linked to HHV-6. To date, a large variety of clinical syndromes have been associated with HHV-6. Age of the patient is the most important factor when considering HHV-6 as a possible cause of infection. It is a major pathogen for children aged 6 to 24 months. In addition, HHV-6 is an important pathogen in the immunocompromised host and may cause ailments of the central nervous system. These later two conditions are most likely to be benefited from the application of anti-viral drug when it becomes available. HHV-6 is an example that virus hides within the immunologic cells and displays a complex interaction with the host cells. The discovery of HHV-6 offers a lesson for clinicians to anticipate new viruses deriving from unexpected sites within the human body; furthermore, HHV-6 provides a model for studying the clinical role of a new herpesvirus.
