Abstract
As the prevalence of coronavirus disease 2019 (COVID-19) increased in the local community, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) universal screening was initiated for all adult patients admitted through the emergency departments (EDs) at Soroka University Medical Centre. Of 8518 patients screened, 288 (3.38%) tested positive. One hundred and thirty-three (46%) positive cases were asymptomatic and would have been admitted without necessary precautions. Patients with symptoms that may be attributable to COVID-19 were significantly older and were admitted through the medical ED. Patients of Bedouin Arab ethnicity accounted for half of those who tested positive, which was double their prevalence in the general population. These findings indicate that universal SARS-CoV-2 screening on adult hospital admission is crucial in areas with a high prevalence of COVID-19.

Abstract
BACKGROUND Given the scarce therapeutic options for carbapenemase-producing Enterobacterales (CPE), aggressive interventions are implemented to limit its spread among hospitalized patients. One such option is contact isolation by cohorting patients in designated units. AIM To describe the experiences in a cohort isolation unit (CIU) due to CPE from the perspectives of patients admitted to this unit and their families, and those of healthcare workers (HCWs) who served in the same unit. METHODS Qualitative study. Face-to-face, semi-structured interviews were conducted in a large tertiary hospital. Twenty-four participants were interviewed, including 15 HCWs, three patients and six family members. Data were coded using thematic analysis. FINDINGS The CIU provoked negative feelings such as fear, risk, loneliness, distrust and unfairness. They also created a sense of conflict with the curative assumptions of hospital care. The poor CIU infrastructure was echoed in perceptions of crowdedness in the site. Moreover, family members described HCWs' inconsistent protective behaviours that led them to a state of vigilance. The hospital infection control unit imparted and refreshed HCWs' knowledge and expected behaviours regarding the CIU. However, patients and families expressed dissatisfaction with the information, guidance and education regarding the 'why and how' of the CIU. They were not guided consistently about recommended behaviours after discharge. In retrospect, HCWs found that the CIU took a psychological, physical and professional toll. CONCLUSION The CIU was planned as a temporary containment mechanism. It needs to develop into a permanent system, capable of addressing the various needs of all involved.

Abstract
The prevalence of skin colonisation with Acinetobacter baumannii (ACBA) on admission to the medical intensive care unit (MICU) was studied in an institution endemic for ACBA bloodstream infections (BSIs). The impact of 4% chlorhexidine gluconate (4% CG) whole-body washing on the patients' ACBA skin colonisation was also determined. A prospective cohort trial in a MICU during March 2002 to December 2003 was performed, with a comparison between the prevalence and incidence of ACBA-BSIs obtained after intervention and retrospectively. During the intervention period, ACBA skin-screening swabs were taken from all patients on admission and periodically until discharge. Patients underwent whole-body disinfection with 4% CG immediately after obtaining the initial cultures. Disinfection was carried out on a daily basis until discharge, regardless of colonisation status. Of the 320 patients at ward admission, 55 (17%) yielded ACBA. The prevalence of ACBA colonisation among the remaining MICU patients was 5.5% at 24h and 1% at 48h following the disinfection regimen (P=0.002, OR: 2.4). Following a second screen, 80% of colonised patients were decolonised. Prevalence of ACBA-BSIs decreased from 4.6 to 0.6 per 100 patients (P < or = 0.001; OR: 7.6) and incidence decreased from 7.8 to 1.25 (85% reduction). We conclude that daily whole-body disinfection with 4% CG significantly reduced ACBA skin colonisation. This regimen may be considered in addition to well-known infection control measures, particularly in institutions with endemic rates of multidrug-resistant ACBA-BSIs.

Abstract
Endocarditis is a devastating complication of implantable cardioverter-defibrillator (ICD) therapy. Partial or complete device removal has been advocated for the treatment of this condition although controlled data are lacking. We present a case of ICD-related endocarditis caused by Bacillus spp. that occurred following coronary angiography. To the best of our knowledge, Bacillus spp. has not been previously described in such context. Moreover, conservative treatment with device retention was successful (no recurrence during a 6-year follow-up). Conservative management may be attempted in selected cases of ICD-related endocarditis, especially, those involving low-virulence organisms and rapid response to antibiotic therapy. This case also suggests that coronary angiography may be associated with transient bacteremia and subsequent infection of indwelling cardiac devices.

Abstract
The efficacy of an educational intervention to prevent blood culture contamination (BCC) in internal medicine was studied in two medical wards in a busy tertiary-care hospital in which blood cultures were obtained by physicians rather than dedicated phlebotomists. Baseline BCC rates were 5.7% and 7.1% in intervention and control wards, respectively (p 0.6), compared with 1.95% and 6.7%, respectively, post-intervention (p < 0.001). Following multivariate analysis, only an absence of intervention was an independent variable associated with BCC. Thus simple educational intervention reduced BCC in internal medicine and was considered to be cost-effective.

Abstract
AIM To determine the prevalence and clinical significance of pleural microbubbles in thoracic empyema. MATERIALS AND METHODS The charts of 71 consecutive patients with empyema were retrospectively reviewed for relevant demographic, laboratory, microbiological, therapeutic and outcome data. Computed tomography (CT) images were reviewed for various signs of empyema as well as pleural microbubbles. Two patient groups, with and without microbubbles were compared. RESULTS Mean patient age was 49 years and 72% were males. Microbubbles were detected in 58% of patients. There were no significant differences between patients with and without microbubbles in regard to pleural fluid chemistry. A causative organism was identified in about 75% of cases in both. There was no difference in the rates of pleural thickening and enhancement, increased extra-pleural fat attenuation, air-fluid levels or loculations. Microbubbles were diagnosed after a mean of 7.8 days from admission. Thoracentesis before CT was performed in 90 and 57% of patients with and without microbubbles (p=0.0015), respectively. Patients with microbubbles were more likely to require repeated drainage (65.9 versus 36.7%, p=0.015) and surgical decortication (31.7 versus 6.7%, p=0.011). Mortalities were 9.8 and 6.6% respectively (p=0.53). CONCLUSION Pleural microbubbles are commonly encountered in CT imaging of empyema but have not been systematically studied to date. Microbubbles may be associated with adverse outcome such as repeated drainage or surgical decortication. The sensitivity and specificity of this finding and its prognostic implications need further assessment.

Abstract
During a 12-month surveillance period, haemodialysis (HD) patients in southern Israel were categorised according to the type of vascular access site (VAS), i.e., arteriovenous (AV) fistula, synthetic AV graft, and cuffed or non-cuffed vascular catheters. Endpoints, expressed as cases/100 patient-months, were: incidence of hospital admission; antibiotic therapy; bloodstream infection (BSI); and VAS infection. These were compared to Centers for Disease Control (CDC) surveillance data, overall and by VAS type. In total, 2568 patient-months were analysed. The VAS distribution differed significantly from CDC data for fistulas (72% vs. 31%), grafts (12% vs. 41%), cuffed catheters (11% vs. 25%) and non-cuffed catheters (5% vs. 3%) (p < 0.0001 in all cases). Of 151 admissions, 32% resulted from infection, for which 112 antibiotic courses (22% vancomycin) were given. There were 16 BSIs, three involving resistant strains. The incidences of admission, antibiotic therapy, BSI and VAS infection were significantly lower overall, compared to CDC rates, as were most VAS-specific endpoints. These differences may be explained by VAS type distribution, although other factors may also be involved. Reporting regional or national surveillance data may allow a standardised comparison of the incidence of HD-associated infections.

Abstract
The impact of attendance by infectious disease specialists (IDS) on hospitalised adults with community-acquired infection was assessed by studying 402 consecutive febrile adults who were admitted randomly to either of two internal medicine wards over a 4-month period and given intravenous antibiotics. In ward 1, patients were attended by IDS, whereas those in ward 2 were attended by physicians from other specialties. In total, 160 patients were treated in ward 1 and 242 in ward 2 (median age 66 years; 49% male). The case-mix was comparable. Only 39% of ward 2 patients underwent minimal fever diagnostic tests compared to 82% in ward 1 (p < 0.001). Ward 1 and 2 patients received 188 and 315 antibiotic courses, respectively, of which 32% and 20% required approval from IDS (p 0.003). Patients in ward 1 were more likely to receive ceftriaxone (7.5% vs. 2%; p 0.002), erythromycin (7% vs. 1.5%; p 0.002) and cefuroxime (48% vs. 26%; p < 0.0001), but were less likely to receive amoxycillin-clavulanate (8% vs. 28%; p < 0.0001). The mean durations of therapy were 3.6 and 3.2 days (not significant), and therapy was deemed to be completely appropriate in 55.5% and 43% of cases, respectively (p 0.012). The crude mortality rates were 6.3% and 7.9%, respectively (not significant), while the medication costs were US dollars 27.4 and US dollars 26.4/patient/antibiotic day, respectively. Regular attendance by IDS resulted in significantly higher rates of accurate diagnosis and appropriate therapy. IDS prescribed more restricted (and expensive) agents, but preferred less expensive agents among unrestricted drugs, thereby offsetting the overall medication costs.

Abstract
The emergence of multidrug-resistant (MDR) Acinetobacter baumannii poses a therapeutic problem. The aim of this study was to assess the risk factors for nosocomial MDR-A. baumannii bloodstream infection (BSI) and the efficacy of ampicillin-sulbactam (A/S) in its treatment. Of 94 nosocomial A. baumannii BSI during the year 2000, 54% involved MDR strains, 81% of which were genetically related. Various risk factors for MDR-A. baumannii were found, of which intensive-care unit admission and prior aminoglycoside therapy were independently associated with MDR-A. baumannii acquisition on multivariate analysis. Of MDR-A. baumannii BSI cases, 65% received A/S and 35% inadequate antibiotic therapy, whereas of 43 non-MDR cases, 86% were treated according to susceptibility and 14% inappropriately with antibiotics to which these organisms were resistant. Crude mortality was comparable in the adequately treated groups. Respective mortalities among patients treated adequately and inadequately were 41.4 and 91.7% (p<0.001). Among severely ill patients, A/S therapy significantly decreased the risk of death (P=0.02 OR=7.64). MDR-A. baumannii has become highly endemic in our institution. A/S appears to be one of the last effective and safe empirical resorts for treatment of MDR A. baumannii BSI.

Abstract
During an 8-month period, 55 episodes of nosocomial bacteremia caused by Enterobacteriaceae species were identified in a tertiary medical center, of which 26 (47%) were caused by extended-spectrum beta lactamase (ESBL)-producing organisms. ESBL production was associated with resistance to aminoglycosides, fluoroquinolones, tetracycline and co-trimoxazole compared with non-ESBL-producing organisms (p < 0.01). By multivariate analysis, infection with ESBL-producing organisms was associated with previous antibiotic therapy and central venous catheter insertion and mortality was associated with heart failure, malignancy and a prolonged hospital stay. Nineteen (73%) patients infected with ESBL-producing organisms received adequate empirical antibiotic therapy and all 26 received adequate definitive therapy. The in-hospital mortality rate did not differ between patients infected with ESBL producers and those infected by non-ESBL-producing Enterobacteriaceae species [13/26 (50%) and 11/29 (38%), respectively] (p > 0.5).

Abstract
Polymicrobial polyarticular septic arthritis is a rare clinical entity, with only a few cases having been reported to date. We report a case due to Streptococcus pyogenes and Staphylococcus aureus in an IVDU, complicated by fatal streptococcal toxic-shock syndrome, and review the current literature. We conclude that whenever polymicrobial polyarticular septic arthritis is diagnosed, a high index of suspicion should be maintained for the detection of locally destructive infectious processes as well as systemic complications, and that a high mortality rate should be expected.

Abstract
Although antibiotic-resistant pneumococci have been frequently detected among day care center (DCC) attendees, the transmission of these organisms to other members of the community has not been adequately studied. Nasopharyngeal cultures were obtained from 152 children and 244 adult members of a closed community (a kibbutz) in Israel. Serotyping, antibiogram, and pulsed-field gel electrophoresis were performed to determine the relatedness of isolated pneumococci. Twenty (30%) of the 66 isolates from children showed decreased susceptibility to penicillin and 9 isolates (14%) were resistant to > or =3 drugs. Of the 16 isolates from adults, 5 (31%) were intermediately resistant to trimethoprim-sulfamethoxazole. Resistant strains carried by DCC attendees were not isolated either from their parents or from other adult members of the community. Despite the high degree of interpersonal contact occurring in a closed community, resistant pneumococcal strains carried by DCC attendees do not appear to be easily transmitted to the adult population, which suggests the existence of an immunological barrier.

Abstract
BACKGROUND Deep-sternal infection is a devastating complication after open-heart surgery. However, the association between infection control practices and deep-sternal infection rates is unclear. METHODS To identify contributors to increased deep-sternal infection rates in our institution, consecutive open-heart surgery patients were prospectively studied during two periods (75 and 40 days), including 66 and 40 patients, respectively. Active monitoring including 149 infection control practices was performed in the operating room and intensive care unit. End-points were deep-sternal infection rates and their relation to infection control practices. RESULTS Mean age was 62+/-11 years and 68% were males. Coronary bypass was performed in 82%. Clinical and surgical features were comparable, except that patients in period 2 were more likely to have heart failure (15% vs 1.5%, p = 0.01) and had a longer mean duration of surgery (277 vs 217 minutes, p < 0.005). Only 57 practices (38%) were adequately performed. The main categories showing inadequate practices were disinfection, traffic, hand-washing, and surgical attire of nonscrubbed personnel, anesthesiologists, and pump technicians. Many categories showed a statistically significant improvement between periods. Deep-sternal infection rates in prestudy and poststudy periods were 10% and 2.8%, respectively (p = 0.007). CONCLUSIONS Active monitoring among personnel involved in open-heart surgery resulted in a significant and sustained decrease in deep-sternal infection rates, through modification of human behavior and improvement of performance standards, probably mediated by the Hawthorne effect. Periodic active monitoring may be a valuable tool to achieve and even sustain such a decrease with tremendous implications on morbidity, costs, and quality of care.

Abstract
A prospective 12-month study was conducted throughout 1998 to determine the frequency of selected bacterial zoonoses as causes of fever among hospitalized Bedouins in southern Israel. One or more zoonoses were diagnosed in 30 (27%) of 110 patients admitted with fever. Brucellosis was diagnosed in 9 (8%), rickettsial infections in 20 (18%), and ehrlichiosis in 2 (2%), one of whom had also evidence of rickettsial spotted fever infection. None of the patients was diagnosed with Q fever. Compared with patients without zoonoses, patients with zoonoses were younger (P = 0.01), fewer of them had underlying conditions (P < 0.02), they had a longer febrile period prior to hospitalization (P = 0.04), a significantly higher proportion had arthralgia (P = 0.02), rash (P = 0.03), and splenomegaly (P = 0.04) and a lower proportion had pathological findings on chest auscultation (P < 0.01). Patients with zoonoses were found to have more commonly anaemia (P = 0.03) and leucopenia (P = 0.02) compared to the rest of the study population. Of the 30 patients with zoonoses 60% were misdiagnosed and only 57% received adequate antibiotic treatment. Zoonotic infections are a common cause of fever in adult Bedouins living in southern Israel. Because of the non-specific features of these diseases they are often misdiagnosed. Blood cultures and multiple serological tests should be used in the investigation of fever in such patients and tetracycline should be considered for initial empirical treatment.

Abstract
OBJECTIVE To evaluate the association between infection with Mycoplasma fermentans (Mf) and rheumatoid arthritis (RA) and other inflammatory arthritides. METHODS Screening of synovial fluid samples (SF) for Mf was done by culture and by polymerase chain reaction (PCR) in 38 and 34 RA patients, respectively, 8 undifferentiated arthritis (UDA), 9 reactive arthritis (ReA), and in 40 other arthritides. The prevalence of antibodies to Mf in these SF was determined by both ELISA and immunoblotting (IB). Antibodies were measured also in sera of 88 RA patients, 28 ReA, 14 UDA, 71 other arthritides, and in 102 healthy blood donors. RESULTS All SF were culture-negative for Mf, while 7 SF were positive by PCR (6/34 RA and 1/8 UDA). SF from patients with other arthritides and ReA were PCR-negative. The prevalence of anti-Mf antibodies in SF of RA patients was significantly higher than in SF of other arthritides (p = 0.01). In 47% (17/38) of all RA (including the 6 PCR-positive patients), the level of antibodies to Mf in their SF was higher than that in sera, compared to 7.5% (3/40) in other arthritides (p = 0.0002). There was no significant difference in the prevalence of serum antibodies to Mf between patients with RA, other arthritides, and healthy controls. By IB with Mf sonicate, binding to Mf peptides P107, P48, and P29 was detected in SF of 7/11 RA patients but not in 11 patients with traumatic arthritis. Specific binding to Mf membrane lipoproteins was also more prevalent in SF of RA patients than in other arthritides (p = 0.038). CONCLUSION The finding that both Mf DNA and specific antibodies to Mf were present in the SF of RA patients suggests that in some RA patients Mf may play a role in initiating or perpetuating synovitis.

Abstract
Brevundimonas vesicularis (B. vesicularis) is a pseudomonad rarely encountered in human infection. A case of nosocomial septicaemia with this organism following open-heart surgery is presented, with a review of the literature. The isolate demonstrated resistance to ciprofloxacin and aztreonam, which has not yet been reported. Treatment with piperacillin/tazobactam resulted in full recovery. A review of the literature reveals that B. vesicularis is a virulent organism involved in serious infections such as central nervous system infection or bacteraemia, some of which are nosocomial. Meanwhile, empiric therapy for B. vesicularis infection should include a broad-spectrum antimicrobial agent until susceptibility results are known.

Abstract
STUDY OBJECTIVES To assess the incidence of tuberculosis in the native and immigrant populations of southern Israel in the period between 1992 and 1997, and to study the prevalence of drug resistance overall and among these subpopulations in the region in order to create guidelines for empirical antituberculous treatment in this region. DESIGN A retrospective population-based study. SETTING The southern district of the country and its tertiary-care hospital. PATIENTS All new culture-proven tuberculosis cases diagnosed in adults residing in the Negev region during the study period. Patients were classified into four groups according to ethnic origin and immigration date. RESULTS During the study period, 249 new cases involving 249 patients were recorded. Immigrants from the former Soviet Union (IFSU) were significantly younger and of male gender, and the incidence among this group rose sharply. IFSU had higher rates of resistance to any drug or drug combination. Isoniazid resistance rates were 16% overall and 32% among IFSU. Resistance to any drug was observed in 29% overall and 50% of isolates among IFSU. Multidrug-resistant tuberculosis was observed in 8.5% and 17%, respectively. CONCLUSIONS The population of southern Israel carries very high rates of drug-resistant tuberculosis, mandating quadruple empiric treatment. IFSU should be regarded as having multidrug-resistant tuberculosis until proven otherwise, and empiric therapy with at least five drugs should be considered. This report demonstrates the influence of immigration on the incidence of tuberculosis, and the great value of local surveillance of population-specific resistance rates in an immigrant society, in order to optimize drug treatment and prevent the dissemination of resistant strains.

Abstract
During the years 1980-1994, 84 patients were treated in our institution due to suspected infective endocarditis (IE). Seventy-one of these episodes occurring in 71 patients, classified definite or possible according to the Duke criteria, were retrospectively analyzed in this study. There were 52 cases of native valve endocarditis, 7 cases of early prosthetic valve endocarditis, and 12 cases of late prosthetic valve endocarditis. The incidence of IE did not change significantly during the study period. The overall mortality rate was 15%. Only one case of drug addiction appeared in our series despite its growing frequency in Israel. Rheumatic heart disease remained the main underlying cardiac condition and Streptococcus viridans remained the most common pathogen. Streptococcus bovis was found to be a significant pathogen causing IE in our patient population, while Staphylococcus aureus appeared to be less frequent. The Duke criteria significantly classified a greater proportion of cases as definitive, as opposed to the von Reyn criteria. Fewer cases were rejected by the Duke criteria, especially culture-negative cases, and those without histopathological confirmation. Application of the Duke criteria permits a more consistent approach to the diagnosis of IE, even in a non-drug-addict patient population.

Abstract
PURPOSE To study the clinical and laboratory features of primary infection with the Epstein-Barr virus in adults who required hospitalization and to assess the difficulty in its diagnosis, the use of diagnostic procedures, and the associated costs of care. PATIENTS AND METHODS We retrospectively identified all adult patients who were diagnosed with primary Epstein-Barr virus infection in our region between 1988 and 1997 using strict serologic criteria. The added costs of unnecessary diagnostic tests and treatment were estimated. RESULTS The analysis included 47 patients (60% men) with a mean (+/-SD) age of 30 +/- 14 years. The prime cause of admission was fever (83%). Compared with patients 35 years of age and older, those younger than 35 years were more likely to have pharyngitis (45% vs 10%) and lymphadenopathy (66% vs 17%). Younger patients also had a greater mean atypical lymphocyte count (17% +/- 14% vs 8% +/- 6%) and more abnormal hepatic enzyme levels. Inpatient work-ups resulted in 309 days of hospitalization, many diagnostic tests, and unnecessary empiric treatments (total 203 days of antibiotic therapy). Overall, unnecessary diagnostic procedures and medical treatments contributed an average of approximately $12,000 in health-care costs per patient. CONCLUSIONS Testing for primary Epstein-Barr virus infection should be a routine step in the investigation of fever in adults of all ages. A higher index of suspicion might prevent unnecessary, sometimes hazardous inpatient work-ups from being performed, thereby reducing health-care expenses.

Abstract
To evaluate the efficacy of granulocyte-colony stimulating factor (G-CSF) prophylaxis in preventing chemotherapy-induced febrile neutropenia in the heterogeneous population of adult cancer patients treated in our institution, all adult cancer patients with either a solid tumor or lymphoma who were admitted for chemotherapy in our institution between 1 January 1994 and 31 July 1995 were retrospectively studied. We compared the characteristics of chemotherapy cycles in which G-CSF was given as prophylaxis and of those with no prophylaxis. In all, 1,079 chemotherapy cycles given to 209 patients were analyzed. Prophylaxis with G-CSF was given in 66 cycles (6%). Patients receiving G-CSF were significantly younger and were more likely to have lymphomas. Febrile neutropenia developed in 40 cycles (4%). There was no difference in the rates of febrile neutropenia, infection, hospitalization or mortality between the study groups in general, and cycles administered to patients being treated for lymphomas in particular. The routine use of prophylactic G-CSF in a mixed cancer patient population with a low incidence of febrile neutropenia is not justified and should be reserved for individual patients with a high likelihood of developing febrile neutropenia.

Abstract
Clostridium sordellii is a Gram-positive spore-forming anaerobic bacillus rarely encountered in human infection. A case of C. sordellii ischio-rectal abscess with rapidly fatal septicaemia is described which complicated ultrasound-guided transrectal biopsy of the prostate, despite ciprofloxacin prophylaxis. Neither C. sordellii ischio-rectal abscess nor ischio-rectal abscess complicating transrectal biopsy have been reported previously. Judging from our experience and the reviewed literature, the addition of prophylactic anti-anaerobe drugs should be strongly considered until an optimal prophylactic regimen will be defined by randomized controlled trials.

Abstract
A patient with leptospirosis who developed oliguric renal failure, massive pulmonary haemorrhage and respiratory failure is described. The patient's clinical condition and arterial oxygenation failed to improve despite vigorous supportive measures. Nitric oxide inhalation and haemofiltration resulted in a marked clinical improvement and subsequent full recovery. We suggest that the addition of haemofiltration and nitric oxide inhalation therapy should be considered in patients with pulmonary haemorrhage and renal failure caused by leptospirosis, in whom conventional therapy fails.

Abstract
Necrotizing fasciitis is a severe life-threatening infection. The portal of entry is usually a site of disruption of the skin barrier. We report a case of fatal necrotizing fasciitis caused by an accidental toothpick injury--a unique injury mechanism not reported this far to cause necrotizing fasciitis. Although toothpick injuries are usually regarded as trivial, it should be kept in mind that they have the potential to cause such a lethal infection.

Abstract
Schistosomiasis, a waterborne trematode infestation, is one of the most widespread parasitic diseases in the world. It occurs in well-defined endemic geographical areas. Schistosomiasis of the appendix was first described by Turner in 1909, and has been reported from endemic areas. However, appendicular schistosomiasis in travelers has not been reported in the English literature. We describe an Israeli traveler with acute appendicitis as the presenting symptom of schistosomiasis, 2 years after a visit to Africa.

Abstract
Bacteroides fragilis is a rare cause of septic arthritis. Most patients with B. fragilis septic arthritis have a chronic joint disease, particularly rheumatoid arthritis, and sources of infection are lesions of the gastrointestinal tract and the skin. We report a 69-year-old male, who developed B. fragilis septic arthritis after pilonidal sinus resection. High level of suspicion of development B. fragilis septic arthritis must be present in patients with chronic joint disease in whom gastrointestinal or skin surgery was previously performed.

Abstract
In order to monitor changes in the frequency and antimicrobial resistance of urinary pathogens over several years, urinary cultures received from outpatient clinics and from a hospital during a period of one month each in 1991 and 1995 were analyzed at a clinical microbiology laboratory. In 1991 and 1995, 1366 and 1534 significant monomicrobic cultures respectively were reviewed. The frequency of Escherichia coli dropped significantly in the outpatient clinics from 70.5% to 61.2% (p < 0.0001). The frequency of Proteus mirabilis, Morganella morganii, Pseudomonas aeruginosa and other gram-negative bacteria also decreased, but the frequency of Klebsiella spp. and Enterobacter spp. increased from 2.6% to 5.8% (p < 0.0001). In the hospital, the frequency of Enterobacter spp. (p < 0.04), Escherichia coli and Morganella morganii declined from 1991 to 1995, whereas the frequency of Pseudomonas aeruginosa (p = 0.001), Acinetobacter spp. (p < 0.05), Klebsiella spp., Proteus mirabilis and other gram-negative rods increased considerably. The frequency of gram-positive aerobic bacteria rose markedly in outpatient specimens from 6.1% to 13.5% (p < 0.0001), while a decline from 14.4% to 9.3% was noted in hospital specimens (p < 0.02). A significant rise in the resistance of Escherichia coli to gentamicin and ciprofloxacin (p < 0.0001) was detected in outpatient isolates. In the hospital, gram-negative urinary pathogens demonstrated increased resistance to ampicillin (p = 0.042), cefuroxime (p = 0.005), gentamicin (p = 0.002) and ciprofloxacin (p < 0.0001) during the study period. The changing etiology of urinary tract infections and the increasing resistance of organisms indicate that periodic monitoring and possibly also modification of empirical therapy are required.

Abstract
A rare case of pleural empyema caused by Leuconostoc spp. is reported. The patient was treated successfully with clindamycin. To our knowledge this is the first reported case of pleural empyema caused by Leuconostoc spp. In a patient with characteristic predisposing factors, such as a serious underlying disease, previous vancomycin therapy and thoracic access device. Our case illustrates that Leuconostoc spp. can cause pleural infection as further evidence of its human pathogenicity.
