        באדם, מכלול המיקרואורגניזמים המורכב המאכלס את הגוף וחי אתו בסימביוזה נקרא 'מיקרוביום'.

        למורכבות הפילוגנטית והגנטית של המיקרוביום השלכות משמעותיות על תפקוד הגוף בבריאות ובחולי.

        טכנולוגיות חדשות לחקר המיקרוביום עשויות לסייע בהבנת שימור הבריאות, האבחון והטיפול במחלות.

        כלל המיקרואורגניזמים המאכלסים את גוף האדם נקראים 'מיקרוביום'. המיקרוביום באדם כולל כ-1014 תאים – פי 10 ממספר תאי האדם. הגנום המשותף של המיקרוביוטה עשוי להכיל פי מאה לערך ממספר הגנים באדם. שילוב הגנומים של האדם ושל המיקרואורגניזמים המאכלסים אותו נקרא מטגנום. שיתוף פעולה בינלאומי ממוקד כעת בחקר מיקרוביום האדם ומתרכז בחמישה אתרים נפרדים: העור, הפה, חללי האף והלוע, מערכת העיכול, ומערכת המין והשתן באישה. אפיון מורכבותו של מיקרוביום האדם במצבי בריאות וחולי, יקדם את הבנת המנגנונים של מצבי תחלואה, ויאיץ את פיתוחם של כלים אבחוניים וטיפולים חדשניים.

        7 cases of listeriosis were diagnosed here between 1988-1997 (6 in last 3 years), or 2.94/100,000 admissions. 2 elderly patients suffered from meningitis and 2 pregnant women presented with premature contractions, 1 of whom delivered a premature, infected baby. 2 other patients had fever and gastroenteritis.

        Listeria monocytogenes was isolated from blood in 4, CSF in 2 and the placenta in 1. It was isolated from those with bacterial meningitis. All patients recovered. Both increased awareness for prevention and better diagnosis are essential to reduce morbidity from this unusual pathogen.

        During the winter of 1995, nasopharyngeal colonization of Streptococcus pneumoniae was evaluated in 204 children with respiratory infection and 107 normal control children. There was no difference in gender or mean age between the groups, and no difference in carrier rate between sick (24.5%) and normal (22%) children (p=0.6). Carrier rates were 19%, 32%, 31% and 17% at 6, 12, 24 and 48 months, respectively. Penicillin-resistant pneumococci (PRP) were found in 42% of sick and 16.6% of normal children, (p<0.05). Resistance to more than 2 antibiotics was found in 28% of sick and in 12.5% of normal children. PRP were found in 67% and 34% of sick children with and without prior antibiotic treatment (p<0.05). We conclude that there is no difference in the carrier rate of Streptococcus pneumoniae between sick and normal children. However, the high prevalence of PRP in children with respiratory infections is probably due to prior antibiotic treatment.

        Onchocerca in Israel

        The parasite Onchocerca volvulus is well-known in its endemic areas in South and Central America and West Africa. It is transmitted to man by simulium flies and causes systemic infection with skin, lymphatic and ophthalmic manifestations and can cause blindness (river blindness). Treatment with Ivermectin is effective but sometimes there is need for surgical intervention to prevent or treat complications. We describe an 11-year-old girl, a new immigrant from Ethiopia, who had a firm mass in her left thigh, caused by Onchocerca volvulus. It was completely excised. This is a very rare condition in Israel, which must be considered in patients coming from endemic areas.

        Fungus-Ball in a Preterm Infant Successfully Treated with Fluconazole

        Very-low-birth-weight premature infants are at high risk for invasive candidiasis. The most commonly involved organ is the kidney. Renal candidiasis may present as fungus-ball obstructive uropathy. We describe unilateral renal obstruction secondary to fungus-ball in a premature infant. Noninvasive, systemic antibiotic treatment, including amphotericin B and fluconazole, resulted in disappearance of the finding.

        Conservative Approach in Children with Central Line Infection

        In 1994-1995, central venous lines were placed in 47 children. All except 1 were of the Broviac type, with subcutaneous tunneling via the internal or external jugular vein. Ages were between 7 days and 16 years. Indications for central venous cannulation were chemotherapy (35 cases), TPN (5), prolonged parenteral antibiotics (4), and repeated blood transfusions (3). The catheter was the source of infection in 13 children (28%), 11 of whom were immunocompromised. The commonly identified bacteria were Staphylococcus aureus (4 cases), Pseudomonas aeruginosa (4), coagulase-negative Staphylococcus (2), and various gram-negative rods (3). All cases were treated with antibiotics through the catheter. The most commonly used were oxacillin (4), ceftazidime (4), and amikacin (4). In 10, treatment succeeded without having to remove the line. In 2 others, tunnel infection developed and the catheter had to be removed. 1 child forcefully removed his catheter before treatment could be started. There were no further complications in the group treated conservatively, except for a case of superior vena cava thrombosis in a girl with recurrent infection of the tunnel. In 7 out of 13 treatment was continued and completed at home. This saved 65 days of hospitalization out of 210. We conclude that the conservative approach to treatment is feasible in most cases of infection when the source is the central venous catheter itself. However, when the tunnel is infected, conservative treatment may be ineffective. Treatment can be carried out in the home, with economy in cost and in use of hospital beds, and is preferred by patients and their parents.

        Incidence, Antimicrobial Resistance and Mortality in Bloodstream Infections in the Critically Ill

        Bloodstream infections (BSI) are 7-fold more common in patients admitted to the intensive care unit (ICU) rather than to other hospital wards. The epidemiology of BSI in critically ill patients in Israel has not been systematically addressed. We examined the annual trends in BSI in patients in a general ICU of evolving patterns of antimicrobial resistance and associated mortality rates for the years 1994-1996. The presence of the systemic inflammatory response syndrome (SIRS) when the first positive blood cultures are taken was a prerequisite for its definition as clinically significant. The unit site, staff, practice guidelines, and type of patient were unchanged during the study period. Blood cultures were positive in 220.7-332.0 patients per 1000 ICU admissions, 18-22-fold more common than in regular ward patients. SIRS was a universal finding in these ICU patients. There was multi-drug resistance for the majority of species cultured, reaching 100% in some cases. Crude hospital mortality of ICU patients, with and without positive blood cultures, was 31-54% and 5-14%, respectively. The introduction of a new blood culture system (Bactec 9240) in 1996 was associated with a 61% increase in the rate of patients with positive blood cultures, accounted for mostly by increased isolation of coagulase-negative staphylococci. However the mortality rate for the latter decreased by 59%, suggesting the possibility of a selective increase in detection of contaminated cultures. Although highly prevalent in the study population and generally defining a patient group with high mortality risk, the specificity of SIRS-associated positive blood cultures may be species and culture-system dependent. These findings re-emphasize the need for both improved control measures for the epidemic proportions of BSI and multi-drug antimicresistance, as well as more specific indicators of the clinicaof positive blood cultures in critically ill patients.
