Nonspecific protection against infectious aerosols of influenza A virus was obtained in Swiss mice after vaccination by aerosols of bacterial ribosomes together with membranal glycoproteins extracted from Klebsiella pneumoniae as the adjuvant. It was shown that repeated stimulant aerosols were necessary to obtain this protection. Routine estimation of serum interferon levels after administration of the association of ribosomes plus membranal glycoproteins to the animals by aerosol or intravenous route showed that there was no correlation between protection and the presence of serum interferon. It was shown that the serum interferon-inducer activity was due to ribosomes. No induction of serum interferon was obtained with membranal glycoproteins used separately. Local liberation of interferon in the mucous membrane of the upper respiratory tract was not investigated.

Diplococcus pneumoniae remains the most frequent cause of community-acquired bacterial pneumonia. Other frequently isolated bacterial pathogens are Hemophilus influenzae, Klebsiella organisms, and Staphylococcus aureus. The etiologic agents most commonly implicated in hopsital-acquired pneumonias are gram-negative bacilli including E. coli, proteus organisms, and species of Klebsiella-Enterobacter, pseudomonas, and Serratia. Among older children and young-adults, Myocoplasma pneumoniae is a common cause of penumonia. Influenza is the most important cause of viral pneumonia in adults, but there is increasing concern about pulmonary infection due to adenoviruses. In those with a history of travel to endemic areas, the diagnosis of fungal pneumonia due to Histoplasma capsulatrum, Blastomyces dermatitides, or Coccidioides immitis, should be considered. Penumonias due to opportunistic fungi (including species of Candida, Aspergillus, and Phycomycetes) and higher bacteria such as Nocardia asteroides are also on the increase, and these arise mostly in compromised hosts. Treatment of pneumonia almost always must be started before culture results are known and in the overwhelming majority of cases, appropriate regimens can be selected after taking an adquate history, doing a careful physical examination, evaluating expectorated sputum for cells and organisms, and examining the chest x-ray. Although anti-infective agents are the mainstay of treatment for most infectious pneumonias, supportive therapy, including adequate tracheobronchial toilet, drainage of abscesses, oxygen inhalation, maintenance of adequate nutrition, and monitoring for super-infection and anti-infective side effects may be life-saving in certain situations.

The of efficiency of spraying as compared to intranasal and digestive ways was tested on Balb/c mouse by using on the one hand an immunostimulant product and on the other various types of test : Myxovirus influenzae by aerosol, Streptococcus pyogenes intranasally, Klebsiella pneumoniae intraperitoneally. Results showed that in the case of influenza virus the immunostimulant inhaled as liquid aerosol or powder aerosol, or deposited on the nasal mucosa was very active. When the test germ was Streptococcus and the contamination intra-nasal, only the homologous way was efficient. When the test germ was Klebsiella pneumonia all inoculation forms except powder aerosol were effective. The comparative study of aerosols granulometry helps grasping this phenomenon.

A method of disinfecting the bronchofiberscope that requires 5 minutes was tested against Mycobacterium tuberculosis, Pseudomonas aeruginosa, Serratia marcescens, Klebsiella pneumoniae, Staphylococcus aureus, Candida albicans, influenza virus, and rhinovirus. The bronchofiberscope was contaminated with either sputum or mucin containing the microorganism. Disinfection was performed by washing the inner channel and the outer sheath with a hexachlorophene detergent followed by a solution containing povidone-iodine, ethanol, and water. A total of 76 specimens was tested; all postdisinfection cultures were sterile with the exception of one containing less than 102 colonies per ml of S. aureus.

Three Bulgarian medicinal plants--Geranium macrorrhizum L. and G. sanguineum L. (Geraniaceae), and Epilobium hirsutum L. (Onagraceae) were analyzed phytochemically. Different polyphenols like flavonoids and tannis have been found to be principal constituents of the plants. A series of water or alcohol extracts was obtained, and their anti-infectious activity was tested. A significant inhibitory effect of water-alcohol extract and of four fractions from the polyphenolic mixture of E. hirsutum on the reproduction of influenza viruses in vitro, in ovo, and in vivo was established. Four extracts from G. macrorrhizum and three extracts from G. sanguineum were studied for in vitro inhibition of the growth of some Gram-negative bacteria (Klebsiella pneumoniae, Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa), Gram-positive bacterium (Staphylococcus aureus), and fungus (Candida albicans). Some geranium extracts caused a strong increase of the survival rate in an infection with K. pneumoniae in mice. Augmentation of the nonspecific host resistance in relation to the influence of the extracts on the classical complement activation pathway was also studied.

Several antitumor substances that effectively inhibited the growth of ascites and solid tumor cells transplanted in mice were isolated from pine cone NaOH extract by acid- and ethanol-precipitation. These antitumor substances were also potent antiviral agents against human immunodeficiency virus, herpes simplex virus and influenza virus; they induced antimicrobial activity against Staphylococcal aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Candida albicans, and induced antiparasite activity against Hymenolepis nana in mice. Chemical analysis of these substances by IR, UV, NMR, ESR and partition chromatography on cellulose-TLC plate disclosed that they had lignin-related structures complexed with sugars or polysaccharides. Chlorinated decomposition of the lignin portion significantly reduced their antiviral activity. In agreement with this, the antiviral activity of synthesized lignins prepared by polymerization of phenylpropanoid precursors was comparable to that of the undecomposed counterparts of the pine cone extract. Acid hydrolysis of the polysaccharide portion significantly reduced the ability of the substances to induce antitumor and antimicrobial activities in mice. With an appropriate eliciting agent, intravenous administration of natural lignified substances transiently induced endogenous production of a cytotoxic factor (possibly tumor necrosis factor) in normal mice. Their priming activity was significantly higher than that of their component units or degradation products. These data suggest the importance of conjugating lignins with polysaccharides for in vivo expression of various kinds of immunopotentiating activity. As possible explanations for their induction of a variety of immunopotentiating activities, these natural and synthetic lignins stimulated macrophage NBT-reducing activity, polymorphonuclear cell (PMN) iodination and splenocyte DNA synthesis and inhibited poly (ADP-ribose) glycohydrolase, RNA-dependent DNA polymerase (reverse transcriptase) and RNA-dependent RNA polymerase activities.

This study also included epidemiologic data to determine the risk factors for the enhancement of these infections. The coagglutination technique for the rapid diagnosis of streptococcus was tried. Five hundred and thirty one samples of pharingeal swabs were obtained from children with ARI. 74% were younger than one year old. Brochopneumonias constituted 66.39% of the cases. In total 357 agents were isolated 35% corresponding to bacteria in pure culture, 23.3% to mixed infections and 11.6% only viruses. The bacteria were: Haemphilus influenza (12.4%), Streptococcus pneumoniae (11%), Staphylococcus aureus (9%), and Klebsiella pneumoniae (6.3%), Mycoplasma pneumoniae was identified in 5 children and M. hominis in 3. Adenoviruses were isolated in 98 patients, parainfluenza in 19, respiratory syncytial virus in 4, influenza in 1 and picornavirus in 2. Predominating socioeconomic factors were: overcrowding, deficient schooling and low income of parents which favor malnutrition. The more frequent agents were constitutes by bacteria. Viruses were a less cause of infection. It was confirmed that babies under 12 months are more susceptible to bacterial pneumonia and prompt treatment with antimicrobial agents lowered the lethality. Low socioeconomic level is a possible predisposing factor for respiratory diseases.

The characteristics of viral-bacterial lesion in the appendix of children with appendicitis are given by means of histologic, histochemical, immunomorphological and morphometric methods. Antigens of influenza viruses A, B, C, entero-, adeno- and paramyxoviruses were observed among which influenza C was found significantly more frequently (64.1%). Viral infection in the majority of cases (79.5%) was found in the association with opportunistic flora, more frequently with E. coli, and less R. aeruginosa and Klebsiella. Analysis of the immunomorphological shifts in the appendix indicated a peculiar dynamics of the antibody production in acute appendicitis: the enhancement of the IgG, IgD and IgE production and the decrease of the production of IgA and IgM. The viral-bacterial effect, the development of the immune responses with IgE hyperproduction and participation in this process of labrocytes and endocrine cells suggest the integration of the two pathogenetic mechanisms-infectious and allergic.

A 10 month prospective study of all adults admitted to Waikato Hospital with community acquired pneumonia was performed to assess aetiology, mortality, hospital stay, and the value of a prognostic index based on that obtained from a British Thoracic Society study. The 92 patients in the survey had a mean age of 56 (range 13-97) years. A microbiological diagnosis was established in 72%; Streptococcus pneumoniae (33%), Mycoplasma pneumoniae (18%), and influenza A virus (8%) were the most common microorganisms. Other causative organisms were Legionella pneumophila (4 cases), Staphylococcus aureus (3), Klebsiella pneumoniae (2), Haemophilus influenzae (2), Nocardia brasiliensis (1), and Acinetobacter calcoaceticus (1). Chlamydia sp, influenza B virus and adenovirus were each found in one case; all were cultured on nasopharygeal aspirates. Aspiration was considered to be the underlying cause in five patients, two with epilepsy and one with pseudobulbar palsy. Five of the six deaths that occurred were in patients over 75 years of age and the other was 69. In four of the six the established causative organisms were Chlamydia sp (1), K pneumoniae (1), and S aureus (2). Patients had a 16 fold increased risk of death if they had two or more of the following on admission: a respiratory rate of 30/minute or more, diastolic blood pressure of 60 mm Hg or less, and either confusion or a plasma urea concentration greater than 7.0 mmol/l.
