A multivariate analysis of 3334 Escherichia coli strains originating from different clinical materials revealed that 50.2% of isolates belonged to the most common 12 (O1, O2, O4, O6, O7, O8, O15, O18, O45, O75, O78, O83) out of 133 serogroups. Haemolysin (Hly) production, mannose resistant haemagglutinating activity for human erythrocytes (MRHA) and colicinogenicity (Col) were recorded in 30, 30 and 36%, respectively. Antigens K1 and K5 were present in 11% and 6.6%, respectively. Association were found among certain serotypes and virulence markers (O1, H-, H7, K1, MRHA, Col; O2, H-, Kl, Col; O4, H-, H5, MRHA, Hly; O6, H-, H1, MRHA, Hly; O6, K5, MRHA, Col; O7, H-, H4, K1, MRHA, Col; O18ac, H7, K1, Col; O18ac, H-, K5, MRHA, Hly; O78, H-, Col (V-type); O83, H-, K1, Col). There were associations among clinical specimens, age of patients, nosocomial group of diseases, serogroups and virulence markers, too (cerebrospinal fluid-CSF-O7, O18ac, O45, O83-K1-newborn meningitis; O78-ColV-meningitis, sepsis, inflammations diseases of premature babies; CFS-O6, MRHA, Hly-adult-meningitis, sepsis, urinary tract infection-UTI-, pneumonia, other inflammatory diseases; blood-O2, O4, O6, O18ac, ONT, K5, MRHA, Hly-sepsis, UTI, hepatic diseases; urine-O1, O2, O4, O6, O18ac, O75, virulence markers fall to differ among upper and lower UTI; faeces-O1, O4, O6, O18ac, O78, virulence markers rare). Associations were also found among animal pathogenicity tests, specimens, serogroups and virulence factors: highly virulent group strains (i.e. LD50 below 10(6)) belonged to serogroups O2, O6, O18ac, possessed antigen K1 (less frequently the presence of MRHA, Hly, K5) and originated mainly from CSF. With mouse lung toxicity test correlations of serogroups (O4, O6, O18ac), antigen K5, MRHA, Hly and specimens (blood) were also shown. However, association was found between the lack of virulence factors and phage insensitivity and also between K5 positivity and sensitivity to phages 16, 17, there were no correlations between serogroups and phage patterns. On the basis of the above-described associations one can find correlations among virulence markers, serotype, and nosological group of diseases. Animal pathogenicity tests give additional data in understanding the pathomechanism of diseases. Correlations between phage patterns and serogroups reveal certain epidemiological relatedness and also virulence of strains.

Febrile episodes occurring in 29 elderly patients (mean age 75 years) with leukemia, from 1988 to 1993, were reviewed. A febrile episode was defined as a temperature of 38 degrees C or greater for at least 6 hours. The number of febrile episodes was 64. The average was 2.2 febrile episodes per patient. Seventy-two percent of febrile episodes occurred when the patients had neutropenia below 100/microliters, while 16% occurred with neutropenia of 101/microliters to 500/microliters. Causative microorganisms were identified in 48% of total febrile episodes. The most common infectious site was the urinary tract which accounted for 25% of total episodes. Pneumonia and septicemia accounted for 22% of total episodes, respectively. Gram-positive cocci were responsible for 66% of microbiologically documented febrile episodes, while 21% were caused by gram-negative bacilli. Gram-positive cocci, particularly staphylococcus aureus, coagulae-negative staphylococcus and enterococci increased compared with a decade ago in our department. Granulocyte colony-stimulating factor (G-CSF) was used 12 times for infection. No significant difference in fever amelioration was seen between G-CSF and non-G-CFS cases.

Meningococcal infections may develop as episodic or endemic cases particularly among children attending day-care centers, boarding schools or among military personnel. Bivalent (A/C) meningococcal vaccine is applied to all new military stuff since 1993 in Turkey. In this report two cases of meningococcemia and meningitis, developed in two soldiers vaccinated with meningococcal vaccine, were presented. The first case was a 21 years old male patient who was admitted to the emergency service with the complaints of high fever, headache, fatigue and vomiting. He was conscious, cooperative and oriented with normal neurological findings. Maculopapular exanthems were detected at the lower extremities. The patient was hospitalized with the initial diagnosis of sepsis or meningococcemia and empirical treatment was initiated with ceftriaxone and dexamethasone. Cerebrospinal fluid (CSF) examination yielded 10 cells/mm3 (lymphocytes) with normal CSF biochemical parameters. A few hours later skin rashes spread over the body rapidly, the symptoms got worse, confusion, disorientation and disorientation developed, and the patient died due to cardiac and respiratory arrest at the seventh hour of his admission. The second case was also a 21 years old male patient who was admitted to the hospital with the complaints of fever, headache, painful urination, confusion and agitation. He was initially diagnosed as acute bacterial meningitis due to clinical (stiff neck, positive Kernig and Brudzinsky signs) and CSF (8000 cells/mm3; 80% polymorphonuclear leukocytes, increased protein and decreased glucose levels) findings. Empirical antibiotic therapy with ceftriaxone was initiated and continued for 14 days. The patient was discharged with complete cure and no complication was detected in his follow-up visit after two months. The first case had an history of vaccination with bivalent (A/C) meningococcal vaccine three months ago and the second case had been vaccinated one month ago. The bacteria isolated from the blood culture of the first case and the CFS culture of the second case, were identified as Neisseria meningitidis by conventional and API NH system (BioMerieux, France). The isolates were serogrouped as W135 by slide agglutination method (Difco, USA), and both were found to be susceptible to penicillin and ceftriaxone. As far as the last decade's literature and these two cases were considered, it might be concluded that N.meningitidis W135 strains which were not included in the current bivalent meningococcal vaccine, gained endemic potential in Turkey. Since N.meningitidis W135 strains may lead to serious diseases, vaccination of the risk population with the conjugate tetravalent meningococcal vaccine (A/C/Y/W135) should be taken into consideration in Turkey.
