Resistance of selected strains of Pseudomonas aeruginosa to low-intensity ultraviolet radiation.

The resistances of 10 strains of Pseudomonas aeruginosa and other microorganisms to an ultraviolet (UV) intensity of 100 muW/cm2 were determined. Organisms were exposed in 2- or 15-ml saline suspensions contained in uncapped polyethylene bottles for increasing periods of time, and the surviving fractions were enumerated. Decimal reduction times were calculated by regression analysis, using the least-squares method.

Age-related humoral antibody responses of AKR/J mice to T-cell dependent and independent antigens.

Humoral responses of groups of 2–3 and 6–7-month-old preleukaemic AKR/J and SWR/J mice were determined following immunization with T-cell dependent (SRBC) and independent ( or ) antigens. Young AKR/J mice responded well to whole SRBC but were less consistent in their responses to lysed SRBC. A greater proportion of the anti-SRBC response in this strain was also due to ME-sensitive antibodies than in the SWR/J strain.

Case reports the treatment of a child foot fetishist.

The history of a childhood foot fetishist is discussed from a developmental, psychodynamic, and therapeutic point of view. Therapy revealed that the symptom, while initially created in response to parental pathology, later led to specific defense mechanisms which were utilized to avoid developmental tasks, resolve ambivalence, and maintain body integrity.
