Distribution of coagulase-negative staphylococci, including the newly described species Staphylococcus schleiferi, in nosocomial and community acquired urinary tract infections.

Four hundred and four coagulase-negative staphylococci were isolated from 4905 urine specimens obtained from 4192 inpatients and outpatients. The distribution of the strains was as follows: 193 Staphylococcus epidermidis (47.8%), 171 Staphylococcus saprophyticus (42.

[Antibody levels against coxsackie B viruses in patients with type 1 diabetes mellitus].

In order to detect if the presence of interrelationship between Coxsackie B Viruses (CBV) and etiology of type 1 diabetes mellitus, antibodies to CBV by microneutralization test serotypes 1, 2, 3, 4, 5 and 6 were investigated in 37 sera obtained from patients with type 1 diabetes mellitus and 100 sera from healthy individuals as control group. No significant difference could found that neutralizing antibody levels to CBV serotypes between in sera obtained from patient with type 1 diabetes mellitus and sera obtained from control group. As a result, interrelationship was not detected between CBV infection and having type 1 diabetes mellitus.

[Detection of influenza B virus antibodies in different age groups using hemagglutination inhibition tests].

Antibody levels against influenza B virus were investigated by using hemagglutination-inhibition (HA-I) tests in 402 sera obtained from different age groups. Hemagglutination antigens were obtained by production of influenza B virus (B/Singapur/LLC 6201) in trypsinized Madin Darby Bovine Kidney (MDBK) cell cultured and they were used in tests. In 355 out of 402 sera (88.

[Use of various cell culture antigens in the indirect fluorescent antibody test for the detection of antinuclear antibodies].

Cell culture antigens were prepared from Vero, BHK-21 and Hep-2 cells which were propagated on slide, for detection antinuclear antibody (ANA) in sera with indirect fluorescent antibody test (IFAT). ANA were investigated in 55 sera which were positive at 1/20 titer with KB IFAT ANA test kits (Virgo), by using these cell culture antigens. 50 sera (91%) with Vero antigens, 46 sera (83%) with BHK-21 antigens and 44 sera (80%) with Hep-2 antigens were found positive at 1/20 titer.
