Of 185 vaginal and 13 wound swabs obtained from febrile females after delivery and abortions, 140 (75.6%) vaginal and 10 (76.9%) wound swabs were positive for bacteria. Infection caused by a single bacterium was found in 100 (71.4%) and mixed infection in 40 (28.5%). E. coli was mainly isolated followed by Staph. aureus and Klebsiella. Fosfomycin was the most effective antibiotic against E. coli and Gentamycin against Staph. aureus.

The incidence of strains producing transferable beta-lactamases capable of hydrolyzing third generation cephalosporins or aminothiazole-oximino substituted monobactams in five Buenos Aires hospitals during a four month period was studied. These enzymes were categorized by 1) MIC greater than or equal to 1 mg/l for third generation cephalosporins; 2) MIC less than 0.06 mg/l for third generation cephalosporins combined with clavulanic acid or sulbactam; 3) sensitivity to imipenem or cephamycins (excluding permeability mutants); and 4) transferable resistance by conjugation. Beta-lactamases hydrolyzing aminothiazole-oximino substituted monobactams were produced by 17.2% of Enterobacteriaceae from intensive care unit patients; 3.6% from inpatients of other units and 1.2% from outpatients. Producers were mainly Klebsiella spp. (45/46) resistant to aminoglycosides (most of them AAC 3'-AAC 6' producers). Three strains had a an isoelectric point of 6.0, two of 6.5 and three of 7.7. TEM-1 beta-lactamase (isoelectric point 5.4) was detected in 6/8 strains. An inocolum effect was observed in 40/46 strains. A Klebsiella pneumoniae strain preserved since 1982 also produced a transferable beta-lactamase hydrolyzing aminothiazole-oximino substituted monobactams.

This study reports the morbidity that resulted from bacterial infections in Melanesian patients with non-insulin-dependent diabetes who attended the Port Moresby General Hospital, Papua New Guinea, between January 1, 1982 and June 30, 1984. Fifty-three of 160 patients with diabetes experienced 66 episodes of infection, 48 of which required inpatient hospital treatment. The average length of stay in hospital was 37.6 days per episode of infection. Of 88 patients who were newly-diagnosed as diabetic during this period, 30 patients initially had presented with a bacterial infection. The lower limb was the site that was infected most frequently, and Staphylococcus aureus and Klebsiella pneumoniae were the usual causative organisms. Eleven patients had bacterial gangrene of the foot; two of these patients were less than 23 years of age, and five patients were not known to have had diabetes previously. Five patients were suffering from pulmonary tuberculosis; the annual incidence of tuberculosis in this study group (12.5 cases/1000 patients) was about 11-times higher than that which has been reported for the general population. Thirteen patients with diabetes died in hospital during the study period. Infection was the cause of death in nine patients and three of these patients were less than 25 years of age. The morbidity of infection can be controlled if diabetes is sought more frequently in patients with infections, and if glycaemia can be controlled. This will have to be achieved through existing primary health-care structures, as resources for diabetes-specific preventive programmes in developing countries will be limited.

Co-trimoxazole or norfloxacin were randomly administered to 44 granulocytopenic children with malignancies in order to prevent bacterial infections. Although more patients in the co-trimoxazole group had febrile episodes (p less than 0.01), the mean of febrile days and the mean of days with systemic antibiotics did not differ significantly in the two groups. Five patients in the co-trimoxazole group had a microbiologically documented infection (four with septicemia) due to Escherichia coli (n = 2), Klebsiella pneumoniae, Pseudomonas aeruginosa, Streptococcus sp. There were four septicemic episodes in the norfloxacin group due to P. aeruginosa, Streptococcus pneumoniae, Streptococcus mitis and Streptococcus faecalis. Compliance was good during administration of both drugs. No signs or symptoms of arthropathy were seen in the norfloxacin group. The number of gram-negative bacilli resistant to co-trimoxazole isolated from stools significantly increased during prophylaxis with co-trimoxazole (p less than 0.001). Norfloxacin did not select resistant strains and was very active in eradicating gram-negative bacilli from stools (27.5% of positive cultures).

A plasmid-encoded beta-lactamase conferring extended broad spectrum resistance including cephamycins was identified in a Klebsiella pneumoniae strain isolated from a patient's wound. Strains harbouring the plasmid pMVP-1 were resistant to penicillins, cephalosporins of all generations (parenteral and new oral compounds) cephamycins, aztreonam, tetracycline, chloramphenicol, sulfonamides and to all aminoglycosides modified by AAC-(6)-I-transferase. beta-lactams still active against these strains were temocillin, ceftazidime, cefpirome, carumonam and the carbapenems imipenem and meropenem. The new cephamycinase (CMY-1) was more strongly inhibited by sulbactam in the majority of combinations than by clavulanic acid or tazobactam. MICs of ceftazidime and carumonam were not reduced by inhibitors in the wild type and the transconjugant. A transferable plasmid (pMVP-1) of about 9.6 x 10(7) dalton was demonstrated by gel-electrophoresis. In the wild type and the transconjugant a beta-lactamase with an isoelectric point of 8.0 was identified. This enzyme CMY-1 is different from the other extended broad spectrum beta-lactamases (TEM-3 to TEM-10, SHV-2 to SHV-5). The incidence of this enzyme may be underestimated, since resistance to cephamycins in Klebsiella and Escherichia coli has so far been regarded as almost exclusively chromosomally encoded and sensitivity of CMY-1 to clavulanic acid is low. Therefore, screening for CMY-1 beta-lactamases by the usual double disk test including clavulanic acid is not sensitive enough to detect CMY-1 producers. Sulbactam (e.g. in combination with ampicillin) disks and a cephamycin should therefore be used as well when screening for super extended broad spectrum (SEBS-) beta-lactamases.

Beta-lactamases play a major part in resistance, as recently redemonstrated by the emergence of extended spectrum beta-lactamases. Since its discovery in FR Germany, SHV-2 has been reported from four continents and CTX-1 (TEM-3) was established in at least 26 French hospitals. More than 12 other enzymes have been individualized. The newest aspect of resistance was probably underestimated because most strains of enterobacteria (mainly Klebsiella pneumoniae) appeared susceptible to oxyimino-beta-lactams as suggested by MICs or diameters of inhibition zone sizes. The double-disk synergy test between amoxicillin/clavulanic acid and oxyimino-beta-lactams was useful to easily detect two susceptibility patterns (CTX, CAZ). Extended spectrum beta-lactamases isolated among nosocomial isolates of enterobacteria (urines, blood, wound, sputum cultures) mostly from intensive care units have spread through hospitals. If outbreaks were described, numerous serotypes were identified in Klebsiella pneumoniae. In France the distribution of extended spectrum beta-lactamases showed that CTX-1 (TEM-3) was well distributed among ten species unlike SHV-type enzymes (SHV-2, SHV-3, SHV-4) preferentially detected in Klebsiella pneumoniae. A majority of strains produced CAZ-type enzymes in Escherichia coli. Some isolates produced two extended spectrum beta-lactamases. In Tunisia extended spectrum beta-lactamase producing strains were mainly identified among pediatric isolates of Klebsiella pneumoniae, Salmonella and Escherichia coli; SHV-2 was predominant but recently CTX-1 and two other types with an isoelectric point of 6.35 and 5.4 (phenotype CTX) were individualized. Because plasmid-encoded, this mechanism was spreading in France among enterobacteria with other resistance markers (e.g. netilmicin, amikacin) for CTX-1 unlike SHV-2.(ABSTRACT TRUNCATED AT 250 WORDS)

One hundred and eighty-seven children with identified bacterial meningitis were treated with intravenous cefotaxime: 15 patients were neonates, 79 infants, and 93 were aged from 1 to 14 years. Causative organisms were: Neisseria meningitidis in 80 cases, Streptococcus pneumoniae in 41, Haemophilus influenzae in 40, enteric gram-negative bacilli in 20 and Staphylococcus spp. in six. Enteric gram-negative bacilli included: Salmonella spp. in 14 cases, Klebsiella pneumoniae in two, and Escherichia coli, Enterobacter sakazakii and Acinobacter calcoaceticus in one each; in one case the organism was not specified. Daily dose of cefotaxime was 150 to 300 mg/kg. Concomitant treatment with an aminoglycoside was used in seven cases. One hundred and seventy-two patients (92.0%) were cured. Fever persisted for a mean of five days and meningeal signs for a mean of four days. Fifteen (8.0%) patients died: most [13] of them were admitted in coma, and two in shock. Death occurred in the first 48 h in ten cases. Sterilization of CSF was achieved in the first 72 h of treatment in 155 (90.1%) of the cured patients. Cefotaxime was well tolerated. CSF penetration of cefotaxime was evaluated in seven patients: concentrations ranged from 0.499 mg/l to 2.829 mg/l. Based on this clinical study, cefotaxime is an effective and safe drug for the treatment of childhood bacterial meningitis.

Septicemia in hematologic malignancies and infection of herpes zoster in cancer patients were studied, and trend in organisms in a cancer hospital was investigated. 1) Septicemia in hematologic malignancies. The success rate of antibiotic therapy for septicemia was 76% if the patients were not under antibiotic therapy when septicemia developed. But recovery from septicemia was only 25% if the patients were undergoing antibiotic therapy when septicemia developed. Some 90% of neutropenic patients under 500/microliters, who were not under antibiotic therapy when septicemia developed, recovered from septicemia if the neutrophil count increased in the following 5 days. Change in the neutrophil count was an important factor determining the success or failure of antibiotic therapy for septicemia. The use of granulocyte colony-stimulating factor may prevent chemotherapy-induced neutropenia. Shortening of the period of neutropenia or preventing its occurrence should reduce the incidence and the severity of infection. 2) Infection of herpes zoster in cancer patients. Thirty-four cancer patients were associated with herpes zoster. Eleven of them were patients with malignant lymphoma and ten of them were patients of breast cancer. Most patients were heavily pretreated by chemotherapy and/or radiotherapy before the development of herpes zoster. Marked lymphocytopenia was observed at the onset of herpes zoster. Absolute lymphocyte count was under 1000/microliters in 71% of these patients. Development of herpes zoster in cancer patients was considered to be due to the depression of cell-mediated immunity which was the result of repeated and continued anticancer therapy. Acyclovir was found to be effective to treat herpes zoster in these patients. 3) Trend of organisms detected in cancer hospital. The frequency of organisms isolated from clinical materials in the National Cancer Center Hospital was compared during the period from 1978 to 1982 and the period from 1983 to 1987. The most common organism detected in both periods was P. aeruginosa and no change in frequency was observed. But the frequency of gram-negative bacilli, E. coli, Klebsiella and Serratia, decreased significantly in the latter period while the frequency of gram-positive cocci, Enterococcus and Staphylococcus increased markedly in the latter period. The use of cephems of third generation in the latter period could be one reason for the recent change of organisms detected in the hospital. Appropriate therapy for infection based on the latest and accurate information should be used.

Nonhematogenous osteomyelitis (NHO) occurred in 24 pediatric patients (ages 8 months to 18 years; median, 14 years; 23 male) admitted from 1980 to 1985. Predisposing factors included compound fracture (12), deep decubiti (4) and foot puncture (3). Infection involved tibia (7), foot bones (6), proximal femur (3) and ulna (2). Patients presented with drainage (64%), pain or tenderness (44%) and fever (32%) lasting for 1 to 180 days (median, 10 days). In 24% both white blood cell count and erythrocyte sedimentation rate were normal. Initial radiographs were nondiagnostic in 42% after compound fractures. Bone cultures were positive in 15 of 18 (83%) patients for: Staphylococcus aureus (9), Staphylococcus epidermidis (2), Pseudomonas aeruginosa (4), Escherichia coli (2), Enterobacter sp. (2), Streptococcus faecalis, Serratia sp., Klebsiella pneumoniae, Achromobacter xylosoxidans, Aeromonas hydrophila and Pseudomonas fluorescens (1 each). Wound cultures failed to predict bone culture results in 12 of 16 patients (75%). NHO recurred in 8 of 19 patients (42%) despite intravenously administered antibiotics for greater than 28 days and debridement in 7 of 8 patients. The indolent nature of NHO complicates diagnosis, especially in patients with recent compound fractures. Only prompt bone culture can confirm the presence of NHO and reliably guide antimicrobial therapy.

From 16,534 admissions, 60 patients, 4 days to 15 years of age, with one or more hospital-acquired urinary tract infections were identified during a 5-year period by a prospective surveillance system. The patient charts were subsequently reviewed to characterize the population at risk for such infections and to describe the course and consequences of these infections. Infections in individual patients ranged from one to greater than 50. The hospital-acquired urinary tract infection rate for the study period was 14.2 infections per 1,000 admissions. In the patients in whom all urinary tract infections were well documented, the following characteristics were defined: (1) 92% (97 of 105) of the infections occurred in catheterized patients; (2) almost half (49 of 105) of the infections occurred in patients exposed to only intermittent catheterization; (3) 28% (29 of 105) of the infections were asymptomatic; (4) fever was the most frequent finding in the symptomatic patients and occurred in 66% (60 of 105); (5) pyuria was found in only 51% (35 of 69) of the urinalyses performed at diagnosis; (6) 85% (89 of 105) of the infections were single-organism infections; (7) 82% (101 of 123) of the causative organisms were Escherichia coli, Pseudomonas sp, coagulase-negative staphylococci, Enterococcus spp, Klebsiella spp, or Enterobacter sp. The urinary tract infections in the 60 patients were not complicated by bacteremia, and no direct relationship between the infections and the minimal mortality in our patients could be established.
