In our hospital Haemophilus influenzae type B seems to be a common cause of acute childhood pneumonia. In the past five years, 34 children with acute Haemophilus pneumonia were identified. Although these children generally had an uncomplicated segmental pneumonia associated with a bacteremia, 13 of the children had pneumonia with a pleural effusion. These children with Haemophilus pneumonia represented 18% of the children hospitalized with systemic Haemophilus disease and almost a third of those hospitalized with acute bacterial pneumonia from whom the causal agent was isolated.

Seven cases of adult Haemophilus parainfluenzae infections diagnosed by positive blood cultures are compared with cases previously reported in the English literature. Three patients had pneumonia, while the others had epiglottitis with meningitis, pharyngitis, arthritis, and endocarditis, respectively. Nonendocarditic manifestations of adult H parainfluenzae infection were reported in four other cases. In addition to the diseases of our patients, H parainfluenzae also has been isolated from cerebral abscesses. Patients did well with antibiotic therapy and there were no deaths. Patients did well with antibiotic therapy and there were no deaths. Report of antibiotic sensitivity testing of 50 strains disclosed 6% of isolates resistant to ampicillin sodium, with all sensitive to chloramphenicol. If the antibiotic sensitivity of the organism is unknown, then chloramphenicol therapy should be instituted until adequate susceptibility studies have been performed. If the organism is sensitive to ampicillin, then this is the drug of choice.

Cefoxitin, a parenteral cephamycin beta-lactam antibiotic, was evaluated for safety and efficacy in children with bacterial infections other than meningitis. Twentysix patients between 3 months and 7 years of age were treated with 80 to 160 mg/kg per day. The most common diagnoses were cellulitis (13 patients), pneumonia (5 patients), and bone and joint infection (4 patients). Nine patients were bacteremic. The most frequently recovered pathogens were Staphylococcus aureus (six patients), Haemophilus influenzae (four patients), and Streptococcus pneumoniae (three patients). All organisms were susceptible to cefoxitin. All 26 children were considered improved or cured. No severe adverse reactions were encountered. Phlebitis (4%), eosinophilia (12%), and elevated liver function tests (4%) were associated with therapy. Cefoxitin appears to be a safe, effective, and well-tolerated antibiotic when used in children with susceptible bacterial infections other than meningitis.

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.

The pathologico-anatomic and even more the histological pattern of experimental Haemophilus parahaemolyticus pleuropneumonia in specific-pathogen-free piglets was found to be characteristic in the peracute, acute, and subacute-chronic stages of the disease. It is an infection which can be morphologically differentiated from other forms of pneumonia in swine primarily by three factors, localisation of the changes, inflammation, and a typical cell response. Changes following experimental Haemophilus parasuis infection were found to occur irregularly on serous skins and, in continuation, in the lung and joints. These were not characteristic and failed to exhibit morphological peculiarities.

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.

Using positive blood, lung, or pleural fluid cultures as definitive criteria for bacterial infection, 43 examples of Hemophilus influenzae type b pneumonia were identified in a 43-month period. The mean age of the patients was 26 months; 12% were older than 5 years of age. Associated infections were found in 34 patients and included upper respiratory infections, otitis media, epiglottitis, and meningitis. Positive nasopharyngeal cultures were observed in only 33%. Radiologically, segmental or lobar infiltrates accounted for 85% of the pneumonias. In two cases, death was attributed to the pneumonia alone. Treatment with penicillin G or ampicillin was equally effective. Our data suggest that H. influenzae pneumonia is commonly a serious infection that cannot be distinguished clinically or radiologically from other pneumonias.

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.

During a 3 1/2-month period, 32 previously healthy young men were first seen typical prodromal symptoms and signs of measles. On admission or within 48 hours of admission, 16 patients (50%) manifested physical signs and roentgenographic evidence of pneumonia. Of these 16 patients, ten (63%) were found to have bacterial suprainfection or colonization confirmed by culture of transtracheal aspirates. From six of these ten patients, Neisseria meningitidis serogroup Y was isolated as the sole organism responsible for suprainfection. In the other patients, Haemophilus species, Neisseria species (not N gonorrheae or N meningitidis), Streptococcus pneumoniae, and beta-hemolytic Streptococcus (not group A or D were isolated alone or in combination. The data suggest that bacterial supra-infection associated with measles pneumonia is not unusual in adults and N meningitidis serogroup Y is a potential pathogen of the lower respiratory tract.
