Thirteen patients with Haemophilus influenzae type b pneumonia are reported to emphasise the clinical, radiographic, and therapeutic aspects of this illness. All but one patient was under 2 1/2 years of age. The presenting complaint was a variable duration of upper respiratory infection and fever in most cases. One-third of patients had radiographic evidence of pleural involvement; one-third showed a patchy bronchopneumonia on roentgenogram; and the remainder had segmental or lobar infiltrates. Clinical response to antibiotic therapy was prompt in patients without pleural involvement.

Cefuroxime is a new parenteral antibiotic with a wider spectrum of activity than earlier cephalosporins and is particularly active against Haemophilus influenzae, including strains resistant to ampicillin due to beta-lactamase production. From 18 centres, 274 patients suffering with 275 infections were treated with cefuroxime sodium using the standard regimen of 750 mg 8-hourly by intramuscular injection. The clinical results showed a 90% success rate in the patients with bronchopneumonia (105), 91% in patients with post-operative pneumonia (74), and 89% in the patients with acute exacerbations of chronic bronchitis (96). Renal function was closely monitored during therapy, and no adverse changes attributable to cefuroxime therapy were seen in any patient, including those who also received frusemide. Two patients (0.7%) developed a rash, although 8 penicillin-allergic patients were treated without incident. From these studies, it can be concluded that 750 mg cefuroxime 8-hourly is effective in the treatment of lower respiratory tract infections. It is suggested that the attributes of this antibiotic may offer several advantages over existing therapies.

Intravenous inoculation of a British strain of Haemophilus somnus resulted either in fatal peracute or chronic forms of H somnus disease. Pleuritis, pericarditis and arthritis were prominent post mortem findings. Intratracheal inoculation led to severe cellulitis and abscess formation in the neck with acute suppurative bronchopneumonia in one calf, while in another, encapsulated abscesses and pleural adhesions were seen. Intraperitoneal inoculation resulted in fatal fibrinous peritonitis in one calf. The organism was readily recovered from the lesions except when overgrown by post mortem contaminants. Rising antibody titres were detected in two calves 12 days after inoculation by a micro-complement fixation test, and the organism was demonstrated in synovial fluid by an indirect fluorescent antibody test. No organisms were recovered from and no lesions were seen in the nervous tissues of the calves in contrast to studies of this disease in the USA.

1. Cefuroxime (CXM) was studied for absorption and excretion in 4 pediatric patients given one shot intravenous injection of 20 approximately 25 mg/kg. The following serum levels were determined: 24.5 approximately 38.0 micrograms/ml at 30 minutes (mean 33.3 +/- 6.1 micrograms/ml), 10.0 approximately 17.0 micrograms/ml at 1 hours (mean 13.9 +/- 3.3 micrograms/ml), 3.4 approximately 7.6 micrograms/ml at 2 hours (mean 5.2 +/- 1.9 micrograms/ml, 0.7 approximately 2.1 micrograms/ml at 4 hours (mean 1.3 +/- 0.6 micrograms/ml, 0.1 approximately 0.3 microgram/ml at 6 hours (mean 0.2 +/- 0.1 microgram microgram/ml). Half-life (T 1/2) was 0.65 approximately 0.88 hour (mean 0.75 +/- 0.10 hour). Urinary levels were 1,280 approximately 7,100 micrograms/ml at 0 approximately 2 hours, 96 approximately 3,400 micrograms/ml at 2 approximately 4 hours, 68 approximately 250 micrograms/ml at 4 approximately 6 hours. Urinary recovery rate at 0 approximately 6 hours was 54.1 approximately 74.4% (mean 61.8 +/- 9.4%). 2. From the study on spinal fluid concentration in pediatric patients with Haemophilus influenzae-induced meningitis, the dose of CXM 52.2 mg/kg was given to 1 pediatric case with this disease by one shot intravenous injection. Spinal fluid levels were presumed as 9.0 micrograms/ml at 30 minutes, 6.8 micrograms/ml at 1 hour, 3.8 micrograms/ml at 2 hours and 1.2 micrograms/ml at 4 hours. 3. CXM was studied in 19 pediatric patients with bacterial infection for clinical efficacy, bacteriological effect and side effect. Clinical result was found good in 1 with purulent meningitis; excellent in 9 out of 15 with acute lobar pneumonia or acute bronchopneumonia, and good in remaining 6 cases; good in 2 with acute bronchitis; excellent in 1 with acute pyelonephritis. This represents efficacy ("excellent" plus "good") rate of 100%. Of 5 strains of H. influenzae presumed as causative organisms, 4 were disappeared and 1 was reduced. Two strains of Streptococcus pneumoniae and 1 strain of Escherichia coli were disappeared. No side effect was noted in terms of clinical symptom. Laboratory examination showed elevation of GOT and GPT in 1 case, but these elevated values returned to normal after the end of the CXM treatment.

Pathological and microbiological studies were conducted on lesions in the lungs of 194 calves from mass rearing facilities. Macroscopically, the lesions were classified into six forms: nonlesion, atelectasis, mild pneumonia, moderate pneumonia, advanced pneumonia, and advanced pneumonia accompanied with abscess. Histopathological examination revealed bronchopneumonia in most of the calves. Lesions more advanced than moderate pneumonia were complicated with desquamation, severe exudation, and necrosis. Bacteriologically, Pasteurella sp. was isolated often in combination with Staphylococcus sp. from about a half of the atelectatic cases. With the development of pneumonic lesions, Pasteurella sp. was isolated at a high frequency in combination with Haemophilus sp., Streptococcus sp., and Corynebacterium sp. Prominent necrosis was more often seen in cases with Pasteurella haemolytica isolated than in cases with only Pasteurella multocida isolated. Mycoplasma sp. and Ureaplasma sp. were isolated from distinctly pneumonic lesions. Advanced pneumonic lesions were observed in many calves over 30 days of age. The importance of environmental and managerial improvement was also emphasized, since calf pneumonia tended to break out in facilities under unsatisfactory conditions in the present work.

In a retrospective morphological and microbiological study, 39 of 55 cases of bovine fibrinous pneumonia were diagnosed as fibrinous pleuropneumonia. Twenty-nine of these 39 (74%) were associated with Pasteurella hemolytica, but only two cases (5%) with P. multocida. In contrast, of the 16 cases classified as fibrinous bronchopneumonia, one (6%) was associated with P. hemolytica, and nine (56%) with P. multocida. In eight cases Mycoplasma and Hemophilus somnus were found in association with either P. hemolytica or P. multocida but were never isolated alone. We concluded that the use of the term pasteurellosis, implying Pasteurella as the cause, is imprecise because lesions associated with P. hemolytica fulfill the criteria of a fibrinous pleuropneumonia, whereas P. multocida is more likely to cause a bronchopneumonia with moderate amounts of fibrin.

Of 222 patients with pneumonia in St Vincent's Hospital, Sydney, in 1972, more were affected by bronchopneumonia (53%) than lobar pneumonia (46%). Two-thirds of the patients were males and 86% were aged 40 years or more. Only 59% had any bacteriological studies performed. It was unusual to isolate pathogens from persons who had received antibiotics before cultures were taken, but of cultures taken from persons not receiving antibiotics, 65% yielded pneumococci. Infections due to Staphylococcus aureus, pseudomonas and enterobacteria were uncommon. Haemophilus influenzae appeared to be a co-pathogen in bronchopneumonia more than in lobar pneumonia. The mortality in lobar pneumonia was acceptably low (4%), but was generally high in bronchopneumonia, being 32% when the condition occurred after surgical operations and 35% when this form of pneumonia complicated other normally non-terminal medical diseases. The mortality was 17% in primary bronchopneumonia.

Loracarbef (LY163892), a carbacephem, is the first of a new class of beta-lactam compounds. A 14-day, double-blind, randomized, parallel treatment study compared loracarbef (400 mg b.i.d.; n = 169) and amoxicillin (500 mg t.i.d.; n = 167) in the treatment of lobar pneumonia and bronchopneumonia. Forty-four patients in the loracarbef group and 40 patients in the amoxicillin group were evaluable for efficacy analysis. Streptococcus pneumoniae and Haemophilus influenzae were isolated from pure or mixed cultures in 45.5% of the evaluable patients, with S. pneumoniae being isolated most frequently. Favourable clinical responses (cure or improvement) in the loracarbef-treated group (42/44; 95.5%) were similar to those in the amoxicillin-treated group (38/40; 95%). A favourable bacteriological response was observed for 36/44 (81.8%) loracarbef-treated patients compared with 28/40 (70%) amoxicillin-treated patients (p = 0.2). Adverse events were similar in both groups. Withdrawal of treatment was required in three patients in each group due to gastrointestinal events or rash/allergic exanthema. These data support the conclusion that loracarbef and amoxicillin have comparable efficacy and safety in the treatment of bronchopneumonia and lobar pneumonia caused by susceptible pathogens. However, loracarbef can be administered twice daily, offering the advantage of improved patient compliance. It is also active against beta-lactamase producing organisms.

Eight hundred and fifty-four piglets which died or were euthanized due to pneumonia or rhinitis atrophicans, were investigated during the period of 1986-1990. Of the animals, 569 showed bronchopneumonia, 218 had pleuritis, pericarditis and peritonitis, 165 had rhinitis atrophicans, 58 pleuropneumonia, and 9 animals had fibrinous pneumonia. Pasteurella multocida, Haemophilus parasuis, Bordetella bronchiseptica, Actinobacillus pleuropneumoniae and Pasteurella haemolytica were isolated in 59.1%, 29.5%, 27.8%, 3.7%, and 2.3% cases of bronchopneumonia respectively. Samples from pigs with pleuritis or rhinitis atrophicans showed Pasteurella multocida in 63.8 and 68.5%, Bordetella bronchiseptica in 28.4 and 39.4%, streptococci in 28.9 and 3.9%, Haemophilus parasuis in 25.2% and 20.6%, Actinobacillus pleuropneumoniae in 5.1 and 5.5%, and Pasteurella haemolytica in 3.2 and 3.0%, respectively Actinobacillus pleuropneumoniae was found in 51 of 58 cases of pleuropneumonia and in 5 of 9 cases of fibrinous pneumonia; 55.6% and 44.4% respectively of those forms of pneumonia were positive for Pasteurella multocida. In the agar diffusion test, 36.8-82.6% of bacterial isolates showed resistance to streptomycin, 7.7-45.5% to sulfamethoxazole-trimethoprim, 5.7-44.6% to tetracycline, 0.2-32.8% to ampicillin, 0.0-16.3% to lincospectin, 2.0-81.2% to furazolidone, 0.4-4.5% to chloramphenicol, 1.3-78.1% to penicillin and 0-0.3% to enrofloxacin.
