[Antigen detection for the diagnosis of bacterial meningitis using the latex agglutination test]. / Bakteriyel menenjit teshisinde latex aglütinasyon yöntemi ile antijen aranmasi.

In this study, etiologic agents were investigated by using routine and latex agglutination test (LA) methods, in the cerebrospinal fluid (CSF) samples taken from 31 patients who were admitted to various Clinics of Ankara Numune Hospital with suspected meningitis. In the culture tests of 31 purulent CSF samples, 6 positive (19.4%) and 25 negative results were obtained. In 13 cases (41.9%) etiologic agents were observed by means of the gram-stained smear of the CSF sediments. LA test was applied to 25 purulent CSF samples of which culture test results were negative. By this method, in 19 cases (76%) positive and in 5 cases (20%) negative results were obtained. Non-specific reaction was only observed in one case (4%).

[The prevalence of intestinal parasites in the students of two primary schools in Ankara]. / Ankara'daki iki ilkokulun ögrencilerinde barsak parazitleri dagilimi.

Four hundred stool samples obtained from two different primary school students were examined for intestinal parasite. Cellophane tape technique was also applied in order to detect the Enterobiasis incidence. It has been observed that the parasite incidence were 13.5% in TED College Students whereas 30.5% in the Incesu Primary School. It has been also concluded that the highest infection rate was connected with two parasites, namely Giardia intestinalis (11.5%) and Enterobius vermicularis (8%).

[Causative agents of urinary tract infections and sensitivity to antibiotics]. / Idrar yolu enfeksiyonlarinda etkenler ve antibiyotiklere duyarlilik.

Our study was done on the outpatients and inpatients of Ankara Numune Hospital who were diagnosed as having urinary tract infections. When 301 cultures with positive results were evaluated. Gram-negative bacteria were found most frequently (E. coli 45.2%, Klebsiella 23.2%, Enterobacter 16.6%, Proteus 11.5%, S. aureus 2.2%, Pseudomonas 1.3%). By using the disc diffusion method, the effectiveness of antibiotic discs of amikacin, tobramycin, netilmycin, cephoperazone, cephotoxime, cephtizoxime, cephradine, cephuroxime, carbenicillin, piperacillin, ofloxacin, nalidixic acid and sulbactam/ampicillin on the isolated strains were investigated. Ofloxacin (92.35%), cephotaxime (72.6%) and nalidixic acid (62.10%) were found to be the most effective while cephradine (7.96%), carbenicillin (11.8%) and piperacillin (14.96%) were found to be the least effective antibiotics.

[An evaluation of the antibacterial effectiveness of bisdequalinium acetate and sodium hypochlorite]. / Bis-deqalinium asetat ve sodyum hipoklorid solusyonlarinin antibakteriyel etkinliklerinin degerlendirilmesi.

The antimicrobial effectiveness of sodium hypochlorite and bis-dequalinium acetate was evaluated in vitro using three different microorganisms. The solutions were prepared in various concentrations and microorganisms were exposed to these solutions for 5, 10, 15 min. then placed into a culture medium, incubated and determined the presence or absence of growth. These results were compared with those obtained with phenol. The following conclusions were drawn from this study: 1. Of the solutions tested Bis-dequalinium acetate was the most effective antimicrobial agent. And 1.25/1000 Bis-dequalinium acetate is appropriate for the clinical use. 2. Sodium Hypochlorite is the least effective compared with Bis-dequalinium acetate and phenol. 2/100 NaOCl is agreeable for the clinical use. 3. Normal saline exhibits no antimicrobial properties.
