Antibacterial activities of monobactam antibiotics (carumonam (CRMN) and aztreonam (AZT] against Gram-negative bacilli isolated from inpatients in the latter half of 1987 were investigated using penicillin (PC: piperacillin (PIPC], cephems (CEPs: ceftazidime (CAZ), cefotaxime (CTX), latamoxef (LMOX), cefsulodin (CFS], carbapenem (imipenem (IPM] and pyridonecarboxylic acids (norfloxacin (NFLX) and ofloxacin (OFLX] as reference antibiotics. A total of 400 strains of 13 species, i.e. Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Proteus mirabilis, Proteus vulgaris, Morganella morganii, Providencia rettgeri, Citrobacter freundii, Enterobacter cloacae, Enterobacter aerogenes, Serratia marcescens, Pseudomonas aeruginosa and Haemophilus influenzae, were used as test strains. 1. CRMN and AZT, both monobactam antibiotics, were roughly comparable in their activities and no resistant strain to these antibiotics were found among isolates of E. coli, Klebsiella spp., Proteus spp., M. morganii, P. rettgeri or H. influenzae and few resistant strains were observed among isolates of S. marcescens. On the other hand, isolates of C. freundii, Enterobacter spp. and P. aeruginosa included rather numerous strains resistant to the monobactam antibiotics. Among these cases, whereas R strains, i.e. resistant strains showing MICs greater than or equal to 50 micrograms/ml, accounted for a large proportion of strains resistant to PC and CEPs, I strains, i.e. intermediately resistant strains showing MICs between 12.5 and 25 micrograms/ml, accounted for a large proportion of strains resistant to the monobactam antibiotics. 2. Strains resistant to PIPC, a PC, were detected with high and more or less uniform frequencies over the entire spectrum of the isolates examined. 3. Antibacterial activities of CEPs varied against different bacterial species. While strains resistant to CTX, CAZ and LMOX were commonly detected with high frequencies among isolates of C. freundii, Enterobacter spp. and S. marcescens, large percentages of LMOX-resistant strains of C. freundii and Enterobacter spp. were of the I type. CTX-resistant strains were also found among isolates of P. vulgaris and M. morganii. Proportions of CEP-resistant strains of P. aeruginosa were 28% for CFS and 12% for CAZ. 4. No or few strains among the isolates of 13 species investigated were resistant to IPM, a carbapenem antibiotic, which showed the most stable antibacterial activity, but it was less active than monobactam antibiotics and CEPs against Klebsiella spp., P. mirabilis and H. influenzae.(ABSTRACT TRUNCATED AT 400 WORDS)

Samples of cerebrospinal fluid from 112 cases of suspected meningitis were tested for the presence of C-reactive protein (CRP), using a qualitative and quantitative slide test. Bacterial meningitis was confirmed in 34 patients, based on CSF and blood culture results, and/or elevated CSF white blood cell (WBC) count and typical biochemical profile. There were 8 patients with early onset, and 3 who had received prior antimicrobial therapy among the 5 neonates, 23 children, and 6 adults with bacterial meningitis. Organisms recovered from CSF, and/or blood, included Haemophilus influenzae 14, Streptococcus pneumoniae 9, Streptococcus group B-5, Staphylococcus aureus 2, E. coli 2 and Klebsiella pneumoniae 1. Slide test was positive for CRP in 33 cases, giving a sensitivity of 97% which compared favourably with elevated CSF protein 33%, decreased CFS glucose 64.7% CSF glucose/blood glucose less than 1/2, 85%, raised CSF WBC 38.2%, raised CSF PMN 61.7%, CSF culture positive 88.2%, and CSF gram-positive 82.5%. Slide test was positive for CRP in 1 of 78 CSF samples negative for bacterial meningitis, giving a specificity of 98%. It was concluded that testing of CSF for CRP is a simple, rapid and accurate method for the laboratory diagnosis of bacterial meningitis, which is particularly appropriate for areas lacking adequate laboratory facilities.

Susceptibilities of 737 strains of 19 species of bacteria to cefotaxime (CTX) were determined based on the inhibition zone diameter obtained by the single-disc method. Four categories were assessed. 1. Susceptibility of clinical isolates to CTX and 6 other antibiotics Against most strains, CTX showed higher antibacterial activity than other drugs (CET, ABPC, SBPC, CMZ, GM, AMK), especially for S. pneumoniae, S. pyogenes and S. agalactiae. Furthermore, CTX was more active than the other antibiotics against E. coli, Indole (+) Proteus, P. mirabilis, Klebsiella sp., S. marcescens, H. influenzae and E. cloacae. 2. Susceptibility of strains isolated from different clinical materials CTX showed the highest antibacterial activity against most strains isolated from sputum, urine, pus, blood and cerebrospinal fluid. However, CTX was occasionally less than potent AMK and GM against strains isolated from bile. Against P. aeruginosa strains derived from clinical materials, the following results were obtained: AMK greater than CFS, FOM greater than CTX greater than GM greater than SBPC 3. Susceptibility of clinical isolates in 7 different fields CTX was the most active antibiotic tested in the fields of internal medicine, pediatrics, urology, obstetrics & gynecology, dermatology and otorhinolaryngology. But in surgery, CTX was less potent than GM and AMK. 4. Susceptibility of clinical isolates of inpatients and outpatients CTX showed excellent activity against many beta-lactamase resistant strains isolated from patients.

In vitro susceptibilities have been investigated against several species isolated from patients with simple and complicated urinary tract infections (UTI) during 1980-1982. Antimicrobial activities of the third generation cephems against E. coli isolated from patients with complicated UTI were found to decrease slightly in 1982. And those against Klebsiella spp. isolated from patients with simple and complicated UTI were also found to decrease similarly. Against P. mirabilis, all the drugs tested have showed relatively potent activities and slight changes in the susceptibility. The marked decrease of susceptibility against Citrobacter spp. isolated from UTI have been found even in the third generation cephems. Especially, Citrobacter spp. exhibited a greater degree of resistant to CZX and CPZ. Strains of P. aeruginosa were on the whole susceptible to the drugs tested, CFS, GM, TOB and AMK, inhibiting 50-80% of the strains tested at 1.56 micrograms/ml. CTX, CZX and CMX seemed most effective against S. marcescens among the third generation cephems, inhibiting 50-90% of the strains tested at 3.13 micrograms/ml.

There is now evidence that chronic fatigue syndrome (CFS) is accompanied by immune disorders and by increased oxidative stress. The present study has been designed in order to examine the serum concentrations of IgA and IgM to LPS of gram-negative enterobacteria, i.e. Hafnia alvei; Pseudomonas aeruginosa, Morganella morganii, Proteus mirabilis, Pseudomonas putida, Citrobacter koseri, and Klebsiella pneumoniae in CFS patients, patients with partial CFS and normal controls. We found that the prevalences and median values for serum IgA against the LPS of enterobacteria are significantly greater in patients with CFS than in normal volunteers and patients with partial CFS. Serum IgA levels were significantly correlated to the severity of illness, as measured by the FibroFatigue scale and to symptoms, such as irritable bowel, muscular tension, fatigue, concentration difficulties, and failing memory. The results show that enterobacteria are involved in the etiology of CFS and that an increased gut-intestinal permeability has caused an immune response to the LPS of gram-negative enterobacteria. It is suggested that all patients with CFS should be checked by means of the IgA panel used in the present study and accordingly should be treated for increased gut permeability.
