Early diagnosis and successful antimicrobial therapy have diminished the frequency of embolomycotic aneurysms, but infected aortic and small vessel aneurysms, arteriosclerotic plaques, and prosthetic grafts are becoming more common. A broad spectrum of pathogens, including Staphylococcus, Salmonella, Enterobacteriaceae, Pseudomonas aeruginosa, and some unusual organisms, are associated with this change. We treated four patients (three with abdominal aortic aneurysms and one with a prosthetic graft) with arterial infections caused by Listeria monocytogenes. Only seven other cases have previously been recorded in the world literature. Infection is suspected when a palpable or radiographically defined aneurysm is present with an otherwise obscure febrile illness. In about one-third of patients, blood cultures have yielded the pathogen. Newer imaging techniques have helped confirm the diagnosis. These infections are best managed by surgical resection in combination with long-term, appropriate antimicrobial therapy with ampicillin or sulfonamides. Unlike other adult listerial infection, except endocarditis, in arterial infection, immunosuppression and malignancy are not predisposing factors.

The microflora and its significance was investigated in 82 leg ulcers in patients with sickle cell disease. Staphylococcus aureus, Pseudomonas aeruginosa and group A streptococci were the most common isolates. The majority of ulcers which yielded these organisms showed signs of local inflammation, regional lymphadenopathy and healed slowly as compared with ulcers which did not show these organisms. Repeat culture swabs demonstrated persistence of these organisms. A topical spray containing neomycin, polymyxin B and bacitracin helped to eradicate these organisms and hastened the healing process of ulcers. Coliforms and anaerobes were also isolated but were transient in nature and of no significance in the pathology of such ulcers.

Infection of peritoneal macrophages from susceptible A/J mice with Legionella pneumophila induced phosphorylation of a 76-kDa protein. The phosphorylation occurred when macrophages were infected with a virulent strain of L. pneumophila but did not occur when they were infected with an avirulent strain or with other bacteria such as either Pseudomonas aeruginosa or Salmonella typhimurium. Also, no phosphorylation of this protein was observed when macrophages were stimulated with either lipopolysaccharide or phorbol myristate acetate. However, phosphorylation did occur in macrophages infected with a virulent strain of L. pneumophila and treated with either erythromycin to inhibit growth or with cytochalasin D to inhibit uptake of L. pneumophila by macrophages. These results support the view that phosphorylation of this protein occurs during the early phases of interaction between L. pneumophila and macrophages. The role of this specific protein in the recognition, intracellular uptake, and growth of L. pneumophila in permissive macrophages remains to be clarified.

The therapeutic perspectives of flomoxef, SCE 2787, cefpirome, cefepime, latamoxef, cefotaxime and of piperacillin plus tazobactam were comparatively evaluated by their in vitro activity against 1119 clinical isolates of 83 bacterial species. Escherichia coli, Klebsiella spp. Enterobacter sakazakii, Proteus spp. and Shigella spp. were about equally susceptible to the cephalosporins (MIC90: 0.06 to 0.5 mg/l), while the MIC90 for piperacillin plus tazobactam was between 2 and 16 mg/l. Enterobacter cloacae, Enterobacter aerogenes and Serratia spp. were most susceptible to SCE 2787, cefpirome and cefepime (MIC90: 0.06 to 2 mg/l) followed by latamoxef, cefotaxime, flomoxef and piperacillin plus tazobactam. For Citrobacter spp., Providencia spp. and Yersinia enterocolitica MIC90 were between 0.06 and 0.5 mg/l. Flomoxef was between 2 to 4 log2 less active against these species but more active than piperacillin plus tazobactam (MIC90: 2 and 8 mg/l). Morganella morganii and Hafnia alvei were most susceptible to cefepime, cefpirome and latamoxef (MIC90: 0.13 to 0.5 mg/l) while cefotaxime (MIC90: 8 mg/l) and piperacillin plus tazobactam (MIC90: 8 and greater than 64 mg/l) were the least active compounds. SCE 2787, cefepime and cefpirome were the most potent beta-lactams against the majority of the 13 species of non-fermentative bacilli (NFB) investigated (MIC90: 0.5 to 16 mg/l). The oxacephems were the least active compounds against NFB. Cefepime was the most active of the compounds included against Pseudomonas aeruginosa (MIC90: 16 mg/l). Haemophilus spp., Neisseria gonorrhoeae and Bordetella pertussis were most susceptible to cefotaxime (MIC90: 0.03 to 0.06 mg/l). Latamoxef had the lowest activity of all compounds against gram-positive cocci. Flomoxef was the most active compound against penicillinase producing Staphylococcus aureus and about equally active as the other betalactams against methicillin susceptible staphylococci of other staphylococcal species.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 75 central venous catheters were used for prolonged chemotherapy in 39 children with acute lymphocytic leukemia and 21 patients with acute myelocytic leukemia. Infection rates were 2.2 per 100 catheter days with the use of cuffed, tunneled, single-lumen Silastic catheters, 2.0 per 1000 catheter days with cuffed, tunneled, double-lumen Silastic catheters, and 0.5 per 1000 catheter days with the use of implanted venous access systems. Eighty-one percent of catheter sepsis episodes were successfully treated without removal of the catheter. All tunnel infections required withdrawal of the catheter for cure. The microorganisms were gram-positive bacteria in 15%, gram-negative bacteria in 7%, and fungi in 4%. Coagulase-negative staphylococci and Pseudomonas aeruginosa were the most commonly isolated organisms. Three of six fatal sepsis episodes were caused by disseminated fungal infections. We conclude that the use of intracorporeal venous catheter systems in patients with acute lymphocytic leukemia is associated with a lower infection rate than that with cuffed, tunneled Silastic single- or double-lumen catheters and that most septicemias can be cured with antimicrobial therapy without removal of the catheter.

An important part of the Infection Control Nurse's activity in the UK is the laboratory-based surveillance of patients with infections that are known to be transmissible, i.e. of 'alert' organisms. We have replaced a manual 'T-card' system in which relevant patient information, microbiology and nursing notes are held on all patients yielding 'alert' organisms. The programme is menu driven, requires minimal coding and runs on a microprocessor with a hard disc. The programme enables surveillance patient information to be entered, edited, archived and recorded. Instant retrieval on screen or hard copy includes summarized or full displays of all patients on all wards, sorted by wards, organism, date or risk category. Archived data may be retrieved within minutes and this avoids having to interrogate the whole laboratory database overnight. To illustrate an additional use of the data stored, we analysed the surveillance activities of the Control of Infection Nurse for one year. Of 203 laboratory diagnoses requiring patient surveillance, 30% were viral infections, of which more than two-thirds were caused by hepatitis B virus; of the 142 bacterial isolates, 27% were multiply antibiotic-resistant Enterobacteriaceae, 25% Pseudomonas spp, 12% Salmonella spp., 9% methicillin-resistant Staphylococcus aureus (MRSA), 7% Group A streptococci and 8% meningococci. These isolates resulted in only four outbreaks involving nine patients or staff. This information has proved useful for auditing the nurse's activity and provides evidence for the cost-effectiveness of infection control.

Between April and September 1991, 415 injured patients were treated at the University Hospital Rebro, Zagreb, 362 at the Department of Surgery and 53 at the Department of Neurosurgery. Infections developed in 15.7% of the injured patients (wound infections in 14.6% and sepsis or meningitis in 1.1% of the injured patients). 88.2% of wound infections as well as all sepsis and meningitis were hospital-acquired infections, while 7.95 of wound infections occurred within 48 h of injuring. The major pathogens, in 90% of cases, were the aerobic bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter species) while 9% of infections were caused by mixed aerobic-anaerobic flora. One injured patient developed clinical features of gas gangrene. Neither streptococcal wound infections nor tetanus were present in this group of the injured patients.

320 recently isolated pathogens, 20 strains from each of 16 species, were investigated using Mueller-Hinton agar and DIN as well as NCCLS standards. The geometric mean of the agar dilution MICs of flomoxef were 0.44 mg/l for Staphylococcus aureus, 0.05 mg/l (Klebsiella oxytoca) to 12.6 mg/l (Enterobacter spp.) for enterobacteriaceae, 33.1 mg/l for Acinetobacter anitratus, 64 mg/l for Enterococcus faecalis, and more than 256 mg/l for Pseudomonas aeruginosa. For disk susceptibility testing of flomoxef a 30 micrograms disk loading and the following interpretation of inhibition zones using the DIN method were recommended: resistant-up to 22 mm (corresponding to MICs of 8 mg/l or more), moderately susceptible-23 to 29 mm (corresponding to MICs from 1 to 4 mg/l), and susceptible-30 mm or more (corresponding to MICs of 0.5 mg/l or less). The respective values for the NCCLS method using the American high MIC breakpoints are: resistant--up to 14 mm (corresponding to MICs of 32 mg/l or more), moderately susceptible--15 to 17 mm (corresponding to MICs of 16 mg/l), and susceptible--18 mm or more (corresponding to MICs of 8 mg/l or less).

The antibacterial activity of the oxacephalosporin flomoxef was evaluated in comparison to cefpirome, cefuzoname, cefotaxime, ceftazidime, and imipenem against fresh clinical isolates. Flomoxef is an antibiotic with strong antibacterial activity against staphylococci including methicillin-resistant strains and streptococci with the exception of Enterococcus faecalis and Enterococcus faecium. It is very active against gram-negative cocci and rods including gram-positive and gram-negative anaerobes. Against Pseudomonas sp. flomoxef has no activity.

Infection control in dentistry focuses on the prevention of cross-contamination among patients, dentists and dental personnel. Difficulties in sterilizing impression materials have led to chemical disinfection as an alternative. This study evaluated the efficacy of disinfectants on the surfaces of silicon and irreversible hydrocolloid materials involved microorganisms. All disinfectants used in this study was effective on Pseudomonas aeruginosa and Candida albicans for silicon impression material and Candida albicans for irreversible hydrocolloid.
