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.

[The antigenic relationship between Brucella abortus, Brucella melitensis and Yersinia enterocolitica serotype 0:3 and 0:9].

Antigenic interrelationship between B. abortus, B. melitensis, Y.

[Determination of antibody levels against coxsackie B virus type 2 and type 3 in sera from blood donors using the microneutralization test].

The presence of antibodies and their titers against Coxsackie B virus type 2 and type 3 (CBV-2 and CBV-3) have been investigated in 208 blood donor's sera obtained from blood Bank of Gülhane Military Medical Academy. The seropositivity against Coxsackie B virus type 2 and type 3 have been determined 59.1% (123/208) and 7.

[Respiratory syncytial virus antibody levels in the 13-25 age group of healthy people using a microneutralization test].

In this study antibody levels to Respiratory Syncytial virus were investigated in 181 serum samples obtained from healthy individuals by using microneutralization test. 25 out of 181 sera (13.8%) were found positive at 1/5 dilution.

[Herpes simplex virus type 2 antibody levels in sera from various age groups using ELISA and IFAT].

We have investigated HSV-2, IgG antibody levels in 180 sera which were obtained from 60 girl students between 18-20 years old, 60 pregnant women between 19-39 years old and 60 young men between 20-22 years old, by using ELISA (Enzyme Linked Immunosorbent Assay) and IFAT (Indirect Fluorescent Antibody Technique). All of the sera obtained from girl students and pregnant women were found negative for HSV-2, IgG antibody by ELISA. However 2 of 60 young men's sera were positive.

[Rubella virus IgG and IgM antibody levels in 17-20 year old female students using ELISA and fluorescent antibody tests].

In this study Rubella virus antibody levels were investigated by using ELISA and IFAT in 94 sera obtained from girl students in Gülhane Military Medical Academy nursing college. We have propagated Rubella virus in BHK-21 cell line for production Rubella virus antigen in order to use IFAT. 81 sera IgG (86.

[Identification of pathogenic Escherichia coli strains in various clinical material and their antibiotic susceptibility].
