In September-December 1998 the epidemic rise of outhospital pneumonia (EP) among children was observed in St. Petersburg, which led to a twofold increase in morbidity rate this year. The study of the etiology of EP during the period of 1998-2001 confirmed the prime role of Streptococcus pneumoniae (74.5%) and, for the first time in Russia, revealed the epidemic outbreak of acute chlamydiosis (Chlamydia pneumoniae), diagnosed in 67.3% of children, the maximum occurrence (87.5%) in 1998 with only 19% of the patients having the disease in the form of monoinfection. The prevalence of S. pneumoniae and C. pneumoniae in the etiology of EP and more severe course of mixed infection suggested that these infective agents played a leading role in the epidemic outbreak of acute respiratory infections in St. Petersburg. 相似文献

A total of 126 adult patients with acute bronchitis were subjected to microbiological, virological and immunological examination. Influenza and other acute respiratory viral infections were detected in 104 (82.5%) cases of acute bronchitis. The results of microbiological examination and the study of local and systemic immunity showed that in 94.4 +/- 2.6% of the patients the development of acute bronchitis was linked with the appearance of acute pneumococcal infection irrespective of the presence, or absence, of virologically and serologically confirmed acute viral or mycoplasmal infections. 相似文献

In 1980-1986 the sensitivity of 2,045 H. influenzae strains isolated from the bronchial contents of patients with inflammatory lung diseases were studied. This study revealed that 60-80% of H. influenzae cultures circulating in Leningrad were sensitive to tetracyclin, chloramphenicol and erythromycin. During the period of observation the tendency towards the decrease of the number of highly sensitive H. influenzae cultures and the increase of the number of strains resistant to all antibiotic preparations was followed. Most of H. influenzae strains isolated in Leningrad were sensitive to penicillin, oleandomycin and ampicillin. In 1983 the appearance of H. influenzae strains, multiresistant to antibiotics, was noted. In 1986 these strains constituted 4.5% of all isolated cultures. 相似文献

The etiology of acute pneumonia (AP) was studied in 229 patients who had the disease simultaneously with influenza (106 patients), other viral and mycoplasmal infections (48 patients), and without concomitant acute viral infections (75 patients). The use of the quantitative microbiological method and the indirect immunofluorescence test with autostrains or Streptococcus pneumoniae strains of serotypes 2, 3, and 6, prevailing in Leningrad in patients with acute inflammatory diseases of the lungs, made it possible to find out the pneumococcal etiology of AP in 95% of patients irrespective of the presence of acute respiratory viral infections. The etiological role of opportunistic bacteria was revealed in 13 AP patients (5.7%); in 2 of them the causative agent of AP was Staphylococcus aureus and in 11, various species of Gram-negative enterobacteria. The latter were the cause of complications in 8 cases of pneumococcal pneumonia. 相似文献

Our work was aimed at developing a simple and effective method of identification of most or all chromosomes of Pleurodeles newts. To this end, we used DAPI staining of the chromomeres of newt lampbrush chromosomes and immunochemical reactions between the ribonucleoprotein (RNP) marker loops and polyclonal antibodies against human zinc-finger protein Ro52 (52-kDa Ro/SS-A). A method has been developed to obtain newt lampbrush chromosome preparations. Cytological maps of P. waltl chromosomes (Spanish population/subspecies) showing distributions of chromomeres and marker loops along the chromosome length were constructed. 相似文献

In acute pneumococcal infection with the clinical picture of acute bronchitis or the exacerbation of chronic bronchitis 88-93% of patients showed the formation of secretory IgA to S. pneumoniae autostrains, i.e. a high correlation between the occurrence of these bacteria in the sputum and the local immune response of the body. The characteristic feature of antipneumococcal secretory IgA is their earlier, more intensive and less prolonged formation in comparison with that of serum antibodies. During the exacerbation of chronic bronchitis only in 28% of the patients secretory IgA to H. influenzae autostrains and low correlation between the formation of secretory and serum antibodies were detected. 相似文献

The study of the sensitivity of 2681 pneumococcal strains to antibiotics, carried out in 1976-1982, demonstrated that most of these strains circulating in Leningrad were sensitive to penicillin, levomycetin, erythromycin and oleandomycin. Penicillin-resistant pneumococcal strains were found to appear in 1980 and later showed a definite increase in number, reaching 4.4% of all strains in 1982. Simultaneously the appearance of levomycetin- and erythromycin-resistant strains and the increase of their relative significance were established. Most of the pneumococcal strains isolated in Leningrad were not sensitive to monomycin, streptomycin and tetracyclin. 相似文献

The dynamics of the antibody formation to S. pneumoniae and C. pneumoniae in children during the epidemic outbreak of non-hospital pneumonia in St. Petersburg in 1998-2001 was studied. For the first time the inhibiting influence of acute C. pneumoniae infection on the synthesis of antibodies to S. pneumoniae in acute mixed infection was established. The prolonged (up to days 29-39 of the disease) circulation of IgM and IgG antibodies in acute chlamydial infection, as well as the prevalence of the primary infectious process, were detected. 相似文献
