Forty consecutive cases of liver abscess from the Department of Medicine III, Singapore General Hospital, from 1978 to July 1983 were reviewed. Nineteen (47.5%) were amoebic, 15 (37.5%) pyogenic and 6 (15%) of unknown aetiology. Of the first 20 cases from 1978 to 1980, amoebic abscesses (60%) predominated. An increased incidence of pyogenic abscess constituting 50% was seen in the next 20 cases. Though all racial groups were affected, a predilection among Indians was seen. Males outnumbered females (4:1), and peak incidence occurred in the 40 to 70 age group (62.5%). Fifty percent presented early (less than one week of symptoms) to hospital. Common physical signs were fever (97.5%) and hepatomegaly (92.5%). Investigations showed leucocytosis in excess of 10,000 WBCs/cmm (87.5%), an ESR of 80 mm/hr (80%) and an elevated alkaline phosphatase of at least twice normal (73.6%). Single abscesses (72.5%) located in the right lobe were more likely to be amoebic. Where abscesses were multiple, they were more likely to be pyogenic (63.6%). Two-thirds of the pyogenic abscesses were due to either Klebsiella species or E. coli. Medical treatment consisted of broad spectrum antibiotics, usually in combination with metronidazole. Aspiration or drainage (open or closed) was employed when indicated. These were carried out more often for pyogenic than amoebic abscesses. Amoebic abscesses responded faster to treatment compared to pyogenic abscesses. Mortality in the first 20 cases prior to 1981 was 30%, being mainly confined to pyogenic abscesses. However, after 1981, there has been no mortality in the ensuing 20 cases.

An immunological approach has been used for the study of alkaline phosphatase evolution in bacteria of the family Enterobacteriaceae. Antisera were prepared against alkaline phosphatase from Escherichia coli and Klebsiella aerogenes and tested against the unpurified alkaline phosphatases of 32 strains of enterobacteria by double diffusion and quantitative micro-complement fixation. The immunological relationships detected among the alkaline phosphatases of enterobacteria agree approximately with those reported for five other enzymes, as well as with the tryptic peptide pattern similarities found for two other enzymes, and with the relationships detected by interspecific deoxyribonucleic acid hybridization tests.

1. Phosphatase synthesis was studied in Klebsiella aerogenes grown in a wide range of continuous-culture systems. 2. Maximum acid phosphatase synthesis was associated with nutrient-limited, particularly carbohydrate-limited, growth at a relatively low rate, glucose-limited cells exhibiting the highest activity. Compared with glucose as the carbon-limiting growth material, other sugars not only altered the activity but also changed the pH-activity profile of the enzyme(s). 3. The affinity of the acid phosphatase in glucose-limited cells towards p-nitrophenyl phosphate (K(m) 0.25-0.43mm) was similar to that of staphylococcal acid phosphatase but was ten times greater than that of the Escherichia coli enzyme. 4. PO(4) (3-)-limitation derepressed alkaline phosphatase synthesis but the amounts of activity were largely independent of the carbon source used for growth. 5. The enzymes were further differentiated by the effect of adding inhibitors (F(-), PO(4) (3-)) and sugars to the reaction mixture during the assays. In particular, it was shown that adding glucose, but not other sugars, stimulated the rate of hydrolysis of p-nitrophenyl phosphate by the acid phosphatase in carbohydrate-limited cells at low pH values (<4.6) but inhibited it at high pH values (>4.6). Alkaline phosphatase activity was unaffected. 6. The function of phosphatases in general is discussed and possible mechanisms for the glucose effect are outlined.

1. Membrane preparations from Klebsiella aerogenes type 8 were shown to transfer glucose and galactose from their uridine diphosphate derivatives to a lipid and to polymer. The ratio of glucose to galactose transfer in both cases was 1:2. This is the same ratio in which these sugars occur in native polysaccharide. Galactose transfer was dependent on prior glucosylation of the lipid. Mutants were obtained lacking (a) glucosyltransferase and (b) galactosyltransferase. The transferase activities in a number of non-mucoid mutants was examined. 2. Glucose transfer was partially inhibited by uridine monophosphate, and incorporation of either glucose or galactose into lipid was decreased in the presence of uridine diphosphate. The sugars are thought to be linked to a lipid through a pyrophosphate bond, and treatment of the lipid intermediates with phenol yielded water-soluble compounds. These could be dephosphorylated with alkaline phosphatase. Transfer of glucuronic acid to lipid or polymer from uridine diphosphate glucuronic acid was much lower than that of the other two sugars. 3. The fate of sugars incorporated into polymer was also followed. Some conversion of glucose into galactose and glucuronic acid occurred. Mutants unable to transfer glucose or galactose to lipid were unable to form polymer. Other mutants capable of lipid glycosylation were in some cases unable to form polymer. A model for capsular polysaccharide synthesis is proposed and its similarity to the formation of other polymers outside the cell membrane is discussed.

Cefmenoxime was evaluated in an open trial consisting of 41 patients. Forty infections in 36 patients could be evaluated. Thirteen patients had pyelonephritis due to Escherichia coli (two bacteremic), Pseudomonas aeruginosa, Klebsiella pneumoniae, or Streptococcus faecalis; all improved and 12 of 13 were clinically cured, but one relapse (S. faecalis) occurred at two weeks. Six patients with cystitis due to E. coli, Citrobacter freundii, Serratia marcescens, P. aeruginosa, or S. faecalis all improved, but relapse or reinfection, or both, occurred in five due to P. aeruginosa, S. faecalis, C. fruendii, or E. coli. Neurogenic bladder or other complications were present in five of 13 patients with pyelonephritis and five of six with cystitis. Ten patients with pneumonia and one with tracheobronchitis due to Hemophilus influenzae, S. pneumoniae, S. agalactiae, or Neisseria meningitidis all improved and seven had resolution without relapse, but P. aeruginosa emerged in two patients, one of whom died. Eight soft tissue infections due to Staphylococcus aureus, Peptococcus prevotti, Streptococcus species, or infections of mixed origin resolved in six. Sterility of blood cultures was obtained in one patient with endocarditis due to S. anginosus, but other therapy was substituted. Clinical resolution of the toxic shock syndrome and subsequent negative endocervical cultures for S. aureus occurred in one. Granulocytopenia of unverified cause in four (with less than 1,500 mm3) and two (with less than 2,000 mm3) was reversible. Headache during treatment occurred in six patients and a possible disulfiram-like effect in three. Elevations of serum glutamic oxalacetic transaminase and alkaline phosphatase occurred in five, Coombs' positivity in two, and diarrhea in three. Clinical efficacy of cefmenoxime was significant. Possible side effects require further study.

A total of 466 patients were treated with cefoperazone. The drug was usually administered by drip infusion of 2 to 4 gm/day. Therapy was described as markedly effective and moderately effective in 64 of 77 patients (83.1%) treated for urinary tract infections; 253 of 316 patients (80.1%) treated for respiratory infections; 37 of 48 patients (77.1%) treated for liver biliary duct infections; ten of 16 patients (62.5%) treated for septicemia; and seven of nine patients (77.8%) being treated for other infections. Overall, cefoperazone was effective 79.6% of all patients treated. With respect to bacteriological activity, the overall eradication rate for gram-negative organisms (including Pseudomonas aeruginosa, Klebsiella sp, Escherichia coli, Haemophilus influenzae, Enterobacter sp, and Proteus sp) was 81% (182/225) and for gram-positive (Staphyloccocus aureus, Streptococcus pneumoniae and Streptococcus faecalis) 90% (36/40). Of 205 patients who failed to respond to previous antibiotic therapy, 67.8% were treated effectively with cefoperazone. Side effects, such as skin eruption, pyrexia and diarrhea, occurred in only 4.8% of patients treated, while laboratory abnormalities, such as elevated glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, and eosinophil values, occurred in only 6.4% of the treated patients. None of these abnormal values were of clinical significance.

Between the years 1981 and 1983 we treated with Ceftriaxone (Cx) 34 children--aged 15 days to 13 years--affected with serious infections: 18 infections of lower respiratory tract, 1 sepsis caused by E. Coli, 1 meningitis with cloudy cerebrospinal fluid, 1 submandibular adenitis with otitis, 1 otitis, 12 infections of the urinary tract caused by Proteus mirabilis, E. Coli, Klebsiella oxitocica and Klebsiella pneumoniae. Whenever bacteria were isolated by cultures, sensibility in vitro to Cx was tested. Cx was given i.m. or i.v. at a dose ranging from 50 to 135 mg/Kg/die according to the age and the seriousness of the infections; in 17 children Cx was administered once daily, in the other patients in two divided doses. The following laboratory measurements were obtained before, during and after treatment: complete blood cell count, platelet count, total bilirubin, creatinine, SGOT, SGPT, alkaline phosphatase and urinalysis. Patients were also monitored daily for clinical signs and symptoms such as fever, general conditions, heart rate, respiratory rate, blood pressure. Twenty children showed a good clinical response (1 sepsis, 1 otitis, 1 adenitis, 1 meningitis, 12 infections of the urinary tract, 4 infections of the lower respiratory tract); urine sterilization was achieved after three days of therapy in all patients with infections of the urinary tract. Remarkable clinical and radiological improvement in 9 patients with infections of lower respiratory tract was observed while in only 4 children with bronchopneumonia therapy was ineffective although the dosage of Cx was adeguate; in these patients a further antibiotic treatment was necessary for a complete recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

Ten inpatients at the Second Department of Internal Medicine, Mie University Hospital, developed infections in the course of treatment for hematopoietic disorders and were administered cefoxitin (CFX). Patients suffered from the following infections: pharyngitis, 2; bronchitis, 2; pneumonia, 2; sepsis, 2; bacteremia, 1; suspected cases of bacteremia, 2; and fever of unknown origin, 1. The number of infections totaled 12 as 1 patient with pharyngitis also developed sepsis and 1 patient with pneumonia developed bacteremia. Duration for the administration of CFX ranged between 5 and 18 days with a total dosage of between 30 and 108 g. Of the 10 patients treated with CFX, 9 were treated concomitantly with micronomicin (MCR), doxycycline (DOXY), or sulbenicillin (SBPC), some were treated concomitantly with only 1 of the drugs and some were treated concomitantly with 2 of the drugs. The following clinical results were obtained: Following treatment, 4 patients were considered "excellent", 5, "good", and 3, "poor". Clinical efficacy rate was 75%. Four strains of Gram-positive cocci (1 strain of S. aureus, 2 strains of S. epidermidis and 1 strain of Streptococcus sp.) and 3 strains of Gram-negative rods (2 strains of P. aeruginosa and 1 strain of E. cloacae) were found in the clinical specimens of the 10 patients. These results differed somewhat from reported data that Gram-negative rods such as E. coli, Klebsiella sp., Pseudomonas sp., Serratia sp., are dominant. No serious side effects requiring cessation of treatment were observed. Elevations in the levels of S-GOT, S-GPT, serum alkaline phosphatase, blood urea nitrogen, etc. were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Physicochemical properties and systemic effects of the enterotoxin of Klebsiella pneumoniae has been studied. The enterotoxin had a molecular weight between 10 000 to 50 000. It was protein in nature, and heat and acid stable, inducing a dilatatory response in the gut. It haemolyzed the erythrocytes of various animals including man. It had a capillary permeability activity. In addition, when administered parenterally it increased the level of blood glucose, serum cholesterol, serum alkaline phosphatase and serum acid phosphatase.

An indirect sandwich enzyme-linked immunosorbent assay for the detection of the polysaccharide antigen of type 3 pneumococcus (SSS-III) is reported. Polystyrene balls with attached anti-SSS-III antibody serve as the solid phase, and antigen is detected using an alkaline phosphatase-labeled antiglobulin conjugate. The reaction is quantitated by spectrophotometry. Concentrations of antigen are estimated by comparison with standard curves prepared with purified SSS-III. For this assay, the practical lower limit of detection of SSS-III is approximately 2 to 3 ng/ml, thus making the test sensitivity about 25 times that reported for counterimmunoelectrophoresis. In preliminary tests with simulated human clinical specimens, none of the body fluids tested (spinal fluid, serum, urine, and sputum) interfered with detection of antigen, nor did they produce false-positive or false-negative results. Streptococcus pneumoniae type 3 whole organisms were readily detected in simulated clinically positive sputum specimens. Cross-reactions were not observed with Haemophilus influenzae type b, group B Streptococcus, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
