The need for an accurate and rapid method of testing ampicillin susceptibility of Haemophilus influenzae, especially strains isolated from patients with meningitis and septicemia, is indisputable. Various methods have been employed for this purpose. Each has advantages and disadvantages. This report describes a modification of the capillary acidometric procedure in which an agar plate is substituted for a tube. All beta-lactamase results obtained by this modified technique correlated with minimal inhibitory concentrations determined in liquid media and the chromogenic cephalosporin substrate method. This modified acidometric agar procedure is a simple, inexpensive, accurate, and rapid way to determine H. influenzae susceptibility to ampicillin.

We have studied cefuroxime, a new beta-lactamase resistant cephalosporin, and cefoxitin, the first cephamycin antibiotic, which is also resistant to many beta-lactamases. Both of these antibiotics have been shown to be microbiologically superior to the "first generation" cephalosporins, cefuroxime having notable activity against Haemophilus influenzae, and cefoxitin against Bacteroides fragilis. Neither antibiotic is absorbed from the gut but, following parenteral administration, serum, urine and bile concentrations are high. Clinical trials have been conducted on both cefoxitin and cefuroxime. The results of these have been satisfactory and untoward side-effects minimal. We suggest that cefoxitin will be particularly valuable in the management of abdominal sepsis and cefuroxime in infections caused by H. influenzae.

The experience with neonatal sepsis at The Johns Hopkins Hospital during 1969-1975 was reviewed. Major pathogens included Escherichia coli, group B streptococcus, other streptococci, and Klebsiella. Nineteen percent of coliform isolates were kanamycin-resistant. The frequency of recovery of E. coli was increased in early-onset sepsis, and the frequency of recovery of Klebsiella was increased in late-onset sepsis. The mortality rate was 23%. The frequency of recovery of E. coli was increased in fatal cases, and mortality was highly correlated with the presence of gastrointestinal catastrophe. Ampicillin and gentamicin are the initial antibiotics of choice for neonatal sepsis at this institution; a penicillinase-resistant penicillin should be added when Staphylococcus aureus involvement is likely, and addition of chloramphenicol or clindamycin should be considered for infants at increased risk for Bacteroides fragilis sepsis.

The case of a kidney allograft recipient, who suffered from several episodes of Salmonella dublin sepsis following massive immunosuppressive therapy to overcome a transplant rejection crisis, is presented. The focus of sepsis was the chronic inflamed gallbladder. The Salmonella dublin strain isolated from the blood during the last episode was found to exhibit multiple resistance to antimicrobiol drugs. Because the resistance phenotype was characteristic for the gramnegative flora of the university hospital, it was suggested that transfer of a resistance plasmid, frequently found in gramnegative enterobacterial isolates, to the Salmonella strain had occurred in the patient. The comparative examination of a Klebsiella pneumoniae strain, representing the hospital flora, and Salmonella dublin revealed that both strains produced the aminoglycoside 3'-phosphotransferase type 1, the 2''-nucleotidyltransferase and the 3''-adenylyltransferase, enzymes responsible for resistance to aminoglycoside antibiotics. Furthermore, in both strains a TEM type beta-lactamase was found to render the organism resistant to penicillins and cephalosporins. Transfer experiments showed that the host ranges of the R-plasmids of both strains were identical. Furthermore, both plasmids were found to be the fi+ type. These data support the view of in vivo transfer of an R-plasmid from the enterobacterial hospital flora to a potential pathogen in a patient.

The puerperal mastitis is a staphylococcal infection of the lactating mamma cumulating during the third and fourth week after delivery. It is seen three times as often after hospital than after house delivery, and it is also more frequent with primiparae than with multiparae. The infection is caused by bacterial hospitalism. Most commonly mamilla and milkducts are infected via the child's nasopharynx. Mastitis rarely occurs in non-nursing women. Early diagnosis before the appearance of all classical inflammatory symptoms is important, to start the treatment with antibiotics before abscess formation takes place. We mentioned Fucidine, Oleandomycin and Oxacillin as staphylococcal-effective, penicillinase-resistent antibiotics. Additionally low-dose X-ray radiation may be given. In case of abscess formation local antibiotic-instillation combined with oral antibiotic treatment should be tried before incision. It is best to incise an abscess only after is complete breakdown. Complications to be looked for are maternal sepsis and staphylococcal infection of the newborn.

The in vitro activity of sisomicin, netilmicin, nafcillin, and oxacillin against 35 strains of Staphylococcus aureus isolated from blood cultures of patients with endocarditis or septicemia was studied. The effects of combinations of either of the two newer aminoglycosides and either of the two penicillinase-resistant penicillins on the killing of S. aureus were investigated. All S. aureus strains were susceptible to the four antibiotics. Enhancement of antistaphylococcal activity was demonstrated by the antibiotic combinations.

Forty-seven strains of Citrobacter diversus were isolated during a 12-month period from clinical material obtained from patients in a general hospital in Israel. The majority of cultures (38) were recovered from urine and wound discharges. There was one case of septicemia. The biochemical reactions of all cultures were typical for this species, except one that was anaerogenic, and they could be divided into five biotypes (a through e). Thirty-nine strains were identified serologically and found to belong to one of seven O groups described by Gross and Rowe (1974). All cultures were sensitive to tetracycline and nalidixic acid. All strains were resistant to carbenicillin and ampicillin and produced beta-lactamase.

To determine current opinions among experts in pediatric infectious diseases for treatment of bacterial sepsis, meningitis and acute otitis media, we polled directors of training programs in January, 1992. Responses were received from 69 centers in the United States and Canada. For initial treatment of presumed bacterial meningitis, the third generation cephalosporins alone or combined with ampicillin have become drugs of choice in all age groups. Most infectious disease programs include dexamethasone in the management of presumed bacterial meningitis for children 2 months of age and older. Third generation cephalosporins are also drugs of choice for presumed sepsis: combined with ampicillin for infants 5 weeks of age; used alone for children 5 months and 12 years of age. Amoxicillin remains the preferred drug for initial treatment of acute otitis media. The combination of amoxicillin and clavulanic acid is favored in the setting of an increased proportion of beta-lactamase-producing bacterial pathogens. Comparison of these results with polls in 1987 and 1989 indicates a shift in recommendations of therapy of presumed bacterial sepsis and meningitis from ampicillin alone or combined with an aminoglycoside or chloramphenicol to use of a third generation cephalosporin alone or combined with ampicillin.

Two cases of serious infection following catfish spine-related injuries are presented, and the literature on this topic is reviewed. The organisms usually involved in such infections are Vibrio species, Aeromonas hydrophila, Enterobacteriaceae, Pseudomonas species, and components of the flora of the human skin. Irrigation, exploration, and culture of these wounds as well as immunization of the patient against tetanus are recommended. Patients with hepatic disease or chronic illness and immunocompromised individuals are at unusually high risk of fulminant infection due to Vibrio and Aeromonas species and should be treated with antibiotics after sustaining a water-associated wound. Patients with normal host defense mechanisms but with late wound care, punctures involving a bone or a joint, progressive inflammation hours after envenomation, fever, or signs of sepsis are at high risk for secondary infection and should receive definitive wound care and antibiotics. For moderate to severe infections, one of the following combinations constitutes a reasonable empirical regimen: (1) a tetracycline and a broad-spectrum, beta-lactamase-stable beta-lactam antibiotic, or (2) a tetracycline, a beta-lactamase-stable penicillin, and an aminoglycoside.

Enterococci are increasing in importance as nosocomial pathogens and causes of severe sepsis in immunocompromised patients. From September to November 1989, a survey of 898 enterococcal isolates showed that 52 had acquired high-level resistance to penicillin and ampicillin (MIC greater than 100 mg/l). These were all Enterococcus faecium, did not produce beta-lactamase and showed high-level resistance to gentamicin and streptomycin as well. The majority were urinary isolates, but a few caused bacteraemia in severely ill patients. The potential spread of these highly-resistant enterococci would limit the therapeutic options for systemic infections.
