Impairment of erythrocyte viscoelasticity is correlated with levels of glycosylated haemoglobin in diabetic patients.

Erythrocytes from diabetic patients exhibit impaired viscoelastic properties when estimated by various methods. We determined erythrocyte filterability through 5-microm pores, in 51 patients with non-insulin-dependent diabetes mellitus, 18 healthy controls, 15 patients with homozygous beta-thalassemia and 15 with beta-thalassemia traits. The filtration measurements were made with a Hemorheometer, which uses the "initial flow rate" principle.

Experimentally induced septic arthritis in chimpanzees infected with Mycoplasma hominis, Mycoplasma pneumoniae, and Ureaplasma urealyticum.

Mycoplasma hominis was isolated in pure culture from septic synovial aspirates from an individual (patient A) during 16 different bouts of exacerbation over a 70-month period of observation. Two isolates, 10(7) and also 10(6) color-changing units (CCU) of the 1620 isolate and 5 x 10(4) CCU of the 1628 isolate, caused inflammation in chimpanzees inoculated intraarticularly. Inflammation was also induced with 10(7) CCU of the 2010B isolate, serovar VII of Ureaplasma urealyticum, recovered from an agammaglobulinemic individual (patient B) with septic polyarthritis and with 3 x 10(6) CCU of the PI-1428 isolate of Mycoplasma pneumoniae.

Experimentally induced Mycoplasma pneumoniae pneumonia in chimpanzees.

Eight chimpanzees were examined. Two served as negative control and six inoculated with Mycoplasma pneumoniae became colonized. Colonization persisted for 28-68, 16-50 and 21 days with an average duration of 47, 32.

Ureaplasma urealyticum colonization of full term infants: perinatal acquisition and persistence during early infancy.

In a prospective study 225 (35%) of 640 pregnant women who delivered at term had vaginal colonization with Ureaplasma urealyticum at the time of delivery. One hundred ninety-three full term infants born to U. urealyticum-colonized mother were cultured from the throat, eyes and vagina within the first 3 days of life.

Lincomycin resistance in methicillin-resistant Staphylococcus aureus strains of hospital origin.

A total of 170 Staphylococcus aureus strains isolated during a one-year period at the University Hospital of Patras Medical School were examined for resistance to a battery of antimicrobial agents by disk diffusion and minimum inhibitory concentration (MIC) determination. Fifty-five isolates were lincomycin- and methicillin-resistant (LMRSA). In the group of 55 LMRSA isolates 13 were also resistant to vancomycin.
