bactericidal action of an average dose of erythromycin in the bronchi. | a study was carried out to establish whether erythromycin stearate was bacteriostatic or bactericidal at the concentrations reached in the bronchial secretion. twenty-two patients suffering from an acute attack of chronic bronchitis, sustained by streptococci, diplococci, staphylococci or h. influenzae sensitive to erythromycin, were treated with 1500 mg erythromycin per day until symptoms regressed, usually within 3 to 5 days. the results showed that after treatment there was a dramatic reducti ... | 1979 | 38063 |
report of iabs committee on avian product standardization. | the international association of biological standardization (iabs) organized an international symposium in august 1973 on the "requirements for poultry virus vaccines" at lyon (france). the proceedings of this symposium were subsequently published as "developments in biological standardization", volume 25. at the conclusion of this symposium, it was resolved that an avian biological products standardization committee should be established, this committee including four subcommittees, each under ... | 1978 | 38158 |
pharmacokinetics and tolerability of a single oral 600-mg dose of doxycycline. | the pharmacokinetics of a single orally administered 600-mg dose of doxycycline (six 100-mg film-coated tablets) was studied in 18 healthy subjects. plasma doxycycline levels remained above 1.35 mumol/l for 48 hours and compared favourably with the mean inhibitory concentrations of doxycycline against the common infecting organisms in chronic bronchitis. in a separate tolerability study in 37 healthy subjects, there was no significant difference between doxycycline and placebo in the incidence o ... | 1979 | 38382 |
detection of experimental bacteremia and fungemia by examination of buffy coat prepared by a micromethod. | rabbits received intravenous injections of bacteria or fungi, and a comparison was made of the abilities of broth cultures, plating after dilution either in saline solution or in distilled water containing triton x-100, and buffy coat examinations to detect the organisms in heart blood. the most sensitive method was broth culture. by microscopy or subculture of buffy coat cells prepared by centrifugation of blood in microhematocrit tubes, organisms were rapidly and regularly detected when their ... | 1979 | 38662 |
bactericidal and bacteriostatic action of chloramphenicol against memingeal pathogens. | the bacteriostatic and bactericidal effects of chloramphenicol, ampicillin, tetracycline, and sulfisoxazole were compared against several potential meningeal pathogens. chloramphenicol is bactericidal at clinically achievable concentrations against haemophilus influenzae, streptococcus pneumoniae, and neisseria meningitidis. it is bacteriostatic against gram-negative bacilli of the family enterobacteriaceae and against staphylococcus aureus. chloramphenicol has proven highly efficacious in the t ... | 1979 | 38742 |
[antibiotics therapy in chronic bronchitis]. | in chronic bronchitis antibiotic therapy is no causative therapy, because infection rarely is the beginning but the complication of an already existing airway disease. while sputum cultures are very limited in their value, blind chemotherapy of bacterial infections by substances like tetracycline, ampicilline, azidocilline or cotrimoxazole is allowed. in cases of additional obstruction a combination with corticosteroids sometimes may be useful. | 1979 | 39882 |
use and efficacy of pneumococcal vaccine in patients with hodgkin disease. | fulminant bacterial sepsis has been described in patients with hodgkin disease who have undergone splenectomy for staging purposes. the organisms commonly associated with sepsis in this setting include streptococcus pneumoniae and haemophilus influenzae. polyvalent pneumococcal vaccine (merck) has recently been licensed and has been suggested for use in patients with hodgkin disease who are at risk for postsplenectomy sepsis. we administered 14-valent pneumococcal vaccine to 24 patients with hod ... | 1979 | 40635 |
pathogenic species of the genus haemophilus and streptococcus pneumoniae produce immunoglobulin a1 protease. | thirty-seven strains of the genus haemophilus and five strains of streptococcus pneumoniae were examined for their ability to produce extracellular enzyme that cleaves immunoglobulin molecules. all strains of h. influenzae, h. aegyptius, and s. pneumoniae elaborated enzyme that selectively cleaved human immunoglobulin a1 (iga1) myeloma proteins but was inactive against a variety of other proteins including human iga2, igg, and igm, porcine and bovine secretory iga, human and bovine serum albumin ... | 1979 | 40878 |
bacterial adherence to pharyngeal cells in smokers, nonsmokers, and chronic bronchitics. | selective adherence to host mucosal surfaces is probably a requirement for colonization and infection by bacteria. since pharyngeal colonization may be an important determinant in the pathogenesis of pneumonia, we studied the adherence of 10 different bacteria to pharyngeal cells obtained from nonsmokers, smokers, and chronic bronchitics. various patterns of adherence among the different groups of subjects were found. young healthy smokers had increased adherence of streptococcus pneumoniae type ... | 1979 | 40879 |
immunoglobulin a1 protease production by haemophilus influenzae and streptococcus pneumoniae. | bacterial strains of haemophilus species and streptococcus pneumoniae were examined for synthesis of the enzyme immunoglobulin a1 (iga1) protease. of 36 h. influenzae strains examined, 35 produced iga1 protease; strains included all six capsular types, unencapsulated variants of types b and d, and untypable h. influenzae. eight haemophilus strains (non-h. influenzae) were studied, and two produced iga1 protease. all 10 strains of s. pneumoniae produced iga1 protease; these strains included 9 dif ... | 1979 | 40880 |
