Ninety-four patients with acquired tracheobronchomalacia were followed up between 1967-1977, for an average of 5.2 years. Fifty-six were still alive at the end of the period, and 47 of these were reexamined. Twenty-one patients had retired on pensions for lung disease. Of the 36 patients who underwent rebronchoscopy, tracheomalacia alone was seen in 3 and tracheobrochomalacia in 33. Six out of the 9 cases of tracheomalacia and all the 5 cases of bronchomalacia had developed into tracheobronchomalacia. The malacia was mild in 6 (17%), moderate in 8 (22%) and severe in 22 (61%), against the figures of the preceding bronchoscopy: 13 (36%), 17 (47%) and 6 (17%), respectively. Mild bronchitic changes were seen in 9 (25%) and severe in 22 (61%) bacterial cultures grew Haemophilus, Proteus mirabilis and Klebsiella, and the culture was positive on 8 occasions (22%). A fungal culture of the bronchial aspirate was positive in 9 cases (25%). No pronounced eosinophilia on the bronchial mucosa was observed.

The antimicrobial activity of cefaclor, a new orally administered cephalosporin derivative, was studied in vitro against a variety of Gram-positive and Gram-negative clinical isolates. Both penicillin-resistant and penicillin-susceptible strains of Staphylococcus aureus were susceptible to cefaclor, with mean MICs of 1.44 and 0.93 microgram/ml, respectively. However, the MBC for penicillin-resistant S. aureus was higher than that for the penicillin-susceptible strains. All strains of Streptococcus pyogenes, Streptococcus viridans, and Streptococcus pneumoniae tested were highly susceptible to cefaclor; all strains of Streptococcus faecalis were highly resistant to cefaclor. Strains of Escherichia coli, Klebsiella sp., Proteus mirabilis, and Hemophilus influenzae were susceptible to cefaclor. Eighty per cent of strains of H. influenzae were inhibited by 5 micrograms/ml of cefaclor. Most strains of Enterobacter sp., indole-positive Proteus, Pseudomonas sp., and Serratia sp. were resistant to cefaclor.

Between January 1976 and March 1977, cerebrospinal fluid samples from 2130 patients at University College Hospital, Ibadan, Nigeria were examined, 130 patients were shown to have pyogenic meningitis. The commonest causative bacteria were Streptococcus pneumoniae (53.8%), Haemophilus influenzae (23%), Neisseria meningitidis (7.7%) and Klebsiella spp. (3%). Most of the infections occurred in very young children: 47% of all patients were under 1 year of age, and 69% were under 5 years old. The overall case fatality rate was 30% (Strep. penumoniae infection 28.6%, H. influenzae and N. meningitidis infection both 20%). All 4 patients with klebsiella infection died. There was a noticeable increase in the incidence of Strep. pneumoniae strains showing resistance to tetracycline, between 1974 and 1976, and this was attributed to the widespread use and abuse of the antibiotic among the general population. Two strains of H. influenzae were found to be resistant to ampicillin; such strains have not previously been reported from Nigeria. The results of the study support the use of a combination of ampicillin and gentamicin in the initial treatment of pyogenic meningitis in Ibadan.

PC-904 was administered to 16 pediatric patients and the following basic and clinical results were obtained. (1) PC-904 was administered 20 approximately 30 mg/kg. The serum peak level of PC-904 after drip intravenous infusion over 1 hour was 66.7 microgram/ml at 1 hour and T 1/2 of PC-904 was 67.8 minutes. PC-904 was administered 25 approximately 30 mg/kg intravenous one shot injection was 49.4 microgram/ml at 1 hour and T 1/2 of PC-904 was 52.2 minutes. (2) Urinary excretion rate was about 20% up to 6 hours after drip intravenous infusion of 20 mg/kg. In a case of intravenous one shot injection of 25 approximately 30 mg/kg, the excretion rate was 11.9 approximately 19.9%. (3) PC-904 was administered 60 approximately 120 mg/kg/day for 3 approximately 48 days to 5 cases of sepsis and bacterial endocarditis, 6 of pneumonia, 2 of sss syndrome (staphylococcal scald skin syndrome) and 3 of pyelonephritis. Clinical effects were excellent in 11 cases and good in 5 cases, effective ratio being 100%. (4) Pseudomonas aeruginosa, Staphylococcus epidermidis, Streptococcus viridans, Acinetobacter anitratus and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904, and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904. Escherichia coli and Klebsiella pneumoniae reduced. (5) As to the side effect by PC-904, s-GOT and s-GPT were elevated in 2 cases. Anemia, rash and fever were observed in each 1 case out of 16 patients though the causal relation with the agent was unknown.

SCE-963 {7beta-[2-(2-aminothiazol-4-yl)acetamido]-3-[({1-(2-dimethylaminoethyl)- 1H-tetrazol-5-yl}thio)methyl]-ceph-3-em-4-carboxylic acid}, a new semisynthetic cephalosporin, showed excellent antibacterial activity against gram-positive and gram-negative bacteria, including Haemophilus influenzae, indole-positive Proteus, Enterobacter species, and Citrobacter freundii. The minimum inhibitory concentrations of SCE-963 against most strains of clinically isolated Escherichia coli, Klebsiella pneumoniae, H. influenzae, and Proteus mirabilis were within the range of 0.2 to 0.78 mug/ml. These activities were about 10 times more potent than those of cefazolin, cephaloridine, and cephalothin. Variations in pH, addition of horse serum, and type of growth medium had no significant effect on the activity of the cephalosporin, but the inoculum size elicited a considerable effect on the activity of beta-lactamase-producing strains of bacteria. SCE-963 exerted bactericidal and bacteriolytic effects on Staphylococcus aureus and E. coli. The pronounced in vitro activity was reflected in the remarkable protection in mice infected with a wide range of gram-negative bacteria, such as E. coli, K. pneumoniae, P. mirabilis, Proteus vulgaris, Proteus morganii, and Proteus rettgeri. The protective effects of SCE-963 in mice infected with E. coli, K. pneumoniae, and P. vulgaris varied according to the challenge dose. The activity of SCE-963 was far more potent when the drug was administered parenterally rather than orally.

A prospective clinical and bacteriological review of the pattern of bacterial infections and chemotherapy among 1931 patients admitted to University College Hospital, Ibadan, between July and September, 1976, showed that 394 patients (20%) had bacterial infections, but 940 patients (49%) received antimicrobial chemotherapy. Thus 58% of the patients were treated either prophylactically or without bacteriological confirmation of infection. Infections of the respiratory tract were commonest (28%), followed closely by wound infections (26%). Septicaemia accounted for 20% of all infections and this was particularly common among children. There was a preponderance of infections due to gram-negative bacteria (69%), with Klebsiella spp. being the most frequently encountered. Among the gram-positive organisms, Staphylococcus aureus accounted for the majority of the infections, particularly infections of wounds, while Salmonellae were responsible for the majority of septicaemias, except among young children, where Klebsiella spp. were predominant. Approximately 90% of urinary tract infections were caused by Klebsiella, Escherichia coli and Proteus spp. Almost all the patients with meningitis were children (93%) and the commonest infecting organisms were Haemophilus influenzae and Streptococcus pneumoniae. The most commonly used antibiotics (penicillin, streptomycin and ampicillin) did not bear a close relationship to the sensitivity patterns of bacteria causing infections in the hospital. Comparison of the bacterial sensitivity patterns for 1963, 1967, 1974 and 1976 showed that the current usage of antibiotics had led over the years to increasing proportions of resistant organisms.

The research was conducted on 191 nasal and pharyngeal swabs from children aged between two and ten years, affected by relapsing diseases of their respiratory organs. The aim has been that of isolating those bacteria whose action cause the most frequent respiratory diseases. They are: Haemophilus influenzae, Staphylococcus C+, Klebsiella pneumoniae, Pseudomonas and other Gram-negative bacteria. The isolated bacteria were submitted to sensitivity tests and to the normally used antibiotics. From this research follow the necessity to know which bacteria play the pathogenous role from patient's serological alterations.

Agglutinin titres to Haemophilus influenzae, Streptococcus pneumoniae, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Proteus vulgaris in the serum of patients with acute exacerbations of chronic bronchitis, patients producing mucoid sputum, and healthy controls were determined. Serological evidence of infection with H. influenzae was found in 38 of 57 patients with acute exacerbations, and Str. pneumoniae infection in 10 of the 57 patients, but was generally absent from healthy control subjects and from patiens producing mucoid sputum. No serological evidence of infection with other organisms named above was found to be associated with exacerbations of chronic bronchitis. Ten patients with acute exacerbations were without serological evidence of infection by any of the bacteria tested.

Cefatrizine (SK&F 60771), a new orally-active semisynthetic cephalosporin antibiotic with broad-spectrum antibacterial activity, was compared with cephalexin and cefazolin for in vitro and in vivo antibacterial activity and pharmacokinetic behavior in laboratory animals. The average MIC values obtained with cefatrizine against gram-positive and gram-negative bacteria were superior to those obtained with cephalexin and somewhat poorer than those of cefazolin. In addition, a large percentage of the enterobacter and enterococcus isolates were found to be susceptible. Cefatrizine had a longer biological half-life and a higher peak serum level than either cefazolin or cephalexin when administered parenterally or orally to mice at 20 mg/kg. It had striking in vivo protective activity in mice infected with Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Hemophilus influenzae, Proteus morganii or Staphylococcus aureus reflecting its superior pharmacokinetic profile in this animal species. A variable pharmacokinetic response between animal species was observed when cefatrizine was administered either orally or parenterally to dogs, squirrel monkeys or rabbits.

The sensitivity of 1,823 bacteriological strains of differing types is shown (E. coli, Klebsiella-Enterobacter-Serratia, Proteus-Providence, Pseudomonas, Salmonella-Shigella-Citrobacter, Haemophilus, Staphylococcus and Streptococcus); all of clinical origin, isolated during March and April, 1975. The methods used were series of double dilutions in Mueller-Hinton agar and the disc-plate method (weight of 50 mug). A comparative study is made of the sensitivity between a part of the present strains (1,725) and another group of 1,664 germs, isolated and observed in January and February, 1973. Some variations are observed which, on general lines, do not seem to be significant, except for Klebsiella-Enterobacter and Serratia.
