description | Enlisting the help of various research institutions across the nation, IKEMOTO et al. have been pooling cultures of clinical isolates of respiratory tract infections and mapping out the correlations between patient backgrounds and the causative bacteria and the changes in the sensitivity spectra of the bacteria to various antibacterial and antibiotic agents annually since 1981. The following is a report of the 1986 findings. During the period from September, 1986 to March, 1987, 558 cases of respiratory infections were reported at 17 institutions across the nation and a total of 657 apparent causative strains were isolated from sputum samples. Of these strains, 75 strains of Staphylococcus aureus, 108 of Streptococcus pneumoniae, 150 of Haemophilus influenzae, 107 of Pseudomonas aeruginosa (non-mucoid production type), 21 of P. aeruginosa (mucoid production type), 32 of Klebsiella pneumoniae, 8 of Escherichia coli, and 55 of Branhamella catarrhalis were subjected to MIC determination of various antibacterial and antibiotic agents to map drug sensitivities. In addition, diagnoses, age distributions by diagnoses, frequencies of infectious diseases, types of isolated bacteria, and usage statuses of the antibacterial and antibiotic agents the times of at isolation were also investigated. MIC determinations were carried out to investigate susceptibilities of causative organisms of respiratory tract infections to various antibacterial and antibiotic agents. From the 558 cases of respiratory tract infections, 657 strains were detected at concentrations not less than 104-6/ml and identified to be the causative organisms. Of these strains, 603 could be used for MIC determination. An overwhelming majority of major causative bacteria, inclusive of H. influenzae and S. pneumoniae, showed sensitivity patterns similar to the sensitivity patterns found a year earlier. P. aeruginosa alone, however, showed some increase in its susceptibility to penicillin and cephem antibiotics. Regarding patient backgrounds, the age distribution was heavily biased towards the higher end of the scale, which patients with ages of 50 or higher accounting for 77.9%, compared to 73.5% in 1985. When the patients were classified by diagnoses, chronic bronchitis, bacterial pneumonia and bronchiectasis accounted for the majority of the infections: 28.7%, 23.3%, and 19.0%, respectively. The percentages of chronic bronchitis and bacterial pneumonia 28.7% and 23.3%, respectively, were somewhat higher |

The percentages of chronic bronchitis and bacterial pneumonia 28.7% and 23.3%, respectively, were somewhat higher in 1986 than in 1985. The disease which was comparatively frequent in all age groups was bronchiectasis, which accounted for 44.0% in patients with ages 29 years or lower, 18.4% in patients between 30 years and 69 years, and 16.7% in patients with ages 70 years or higher. The next most frequent infection was bacterial pneumonia. Another finding of note was that whereas acute bronchitis was more frequent among young patients, chronic bronchitis was more prevalent in elderly patients. When classified by diagnoses, H. influenzae, P. aeruginosa, and S. pneumoniae were frequent in most infectious diseases. Of 355 strains isolated from patients with chronic bronchitis, diffuse panbronchiolitis or bronchiectasis, P. aeruginosa, H. influenzae, and S. pneumoniae accounted for 27.9%, 26.2%, and 18.0%, respectively. However, the incidence of H. influenzae has been declining yearly, while the frequencies of P. aeruginosa and S. pneumoniae are increasing. It is noteworthy that the includence of B. catarrhalis is on a slow but steady increase. In cases of bacterial pneumonia, the frequency of S. aureus was comparatively high.</description><identifier>ISSN: 0368-2781</identifier><identifier>EISSN: 2186-5477</identifier><identifier>DOI: 10.11553/antibiotics1968b.42.2324</identifier><identifier>PMID: 2695657</identifier><language>jpn</language><publisher>Japan: Japan Antibiotics Research Association</publisher><subject>Anti-Bacterial Agents - pharmacology ; Bacteria - drug effects ; Bacteria - isolation & purification ; Bronchiectasis - microbiology ; Bronchitis - microbiology ; Chronic Disease ; Humans ; Microbial Sensitivity Tests ; Middle Aged ; Multicenter Studies as Topic ; Pneumonia - microbiology ; Respiratory Tract Infections - microbiology</subject><ispartof>The Japanese Journal of Antibiotics, 1989/11/25, Vol.42(11), pp.2324-2353</ispartof><rights>Japan Antibiotics Research Association</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/2695657$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>IKEMOTO, HIDEO</creatorcontrib><creatorcontrib>WATANABE, KAZUYOSHI</creatorcontrib><creatorcontrib>KOSAKAI, NOZOMU</creatorcontrib><creatorcontrib>HAYASHI, YASUYUKI</creatorcontrib><creatorcontrib>OGURI, TOYOKO</creatorcontrib><creatorcontrib>KONDOU, TAKAHITO</creatorcontrib><creatorcontrib>SAITOU, AKIRA</creatorcontrib><creatorcontrib>MATSUMIYA, HIDEMI</creatorcontrib><creatorcontrib>UEDA, KYOKO</creatorcontrib><creatorcontrib>TERAI, TSUGIO</creatorcontrib><creatorcontrib>TANNO, YASUO</creatorcontrib><creatorcontrib>NISHIOKA, KIYO</creatorcontrib><creatorcontrib>ARAKAWA, MASAAKI</creatorcontrib><creatorcontrib>WADA, KOUICHI</creatorcontrib><creatorcontrib>IGARASHI, KENICHI</creatorcontrib><creatorcontrib>SHIMAZU, YOSHINORI</creatorcontrib><creatorcontrib>YAKATA, MINORU</creatorcontrib><creatorcontrib>OZAKI, KYOKO</creatorcontrib><creatorcontrib>SEKINE, OSAMU</creatorcontrib><creatorcontrib>AOKI, NOBUKI</creatorcontrib><creatorcontrib>OHSHIMA, HIROSHI</creatorcontrib><creatorcontrib>WATANABE, KYOKO</creatorcontrib><creatorcontrib>TANIMOTO, HIROICHI</creatorcontrib><creatorcontrib>NAKADA, KOUICHIRO</creatorcontrib><creatorcontrib>NAKAMORI, YOSHITAKA</creatorcontrib><creatorcontrib>CHONABAYASHI, NAOHIKO</creatorcontrib><creatorcontrib>NAKATANI, RYUOU</creatorcontrib><creatorcontrib>YOSHIMURA, KUNIHIKO</creatorcontrib><creatorcontrib>KABE, JUNZABUROU</creatorcontrib><creatorcontrib>KUDO, KOUICHIRO</creatorcontrib><creatorcontrib>YAMAMOTO, YUMIKO</creatorcontrib><creatorcontrib>UZAWA, TAKESHI</creatorcontrib><creatorcontrib>TAMURA, SHIZUO</creatorcontrib><creatorcontrib>OKADA, JUN</creatorcontrib><creatorcontrib>KOBAYASHI, HIROYUKI</creatorcontrib><creatorcontrib>TAKEDA, HIROAKI</creatorcontrib><creatorcontrib>OSHITANI, HIROSHI</creatorcontrib><creatorcontrib>KAWAI, SHIN</creatorcontrib><creatorcontrib>SHIMADA, KAORU</creatorcontrib><creatorcontrib>ITO, AKIRA</creatorcontrib><creatorcontrib>KAMINAGA, YOUICHIRO</creatorcontrib><creatorcontrib>SOEJIMA, RINZOU</creatorcontrib><creatorcontrib>NIKI, YOSHIHITO</creatorcontrib><creatorcontrib>ANDOU, MASAYUKI</creatorcontrib><creatorcontrib>SUGA, MORITAKA</creatorcontrib><creatorcontrib>YAMANE, NOBUHISA</creatorcontrib><creatorcontrib>TOSAKA, MASAKAZU</creatorcontrib><creatorcontrib>HARA, KOUHEI</creatorcontrib><creatorcontrib>YAMAGUCHI, KEIZO</creatorcontrib><creatorcontrib>SUGAWARA, KAZUYUKI</creatorcontrib><creatorcontrib>SHIMOGUCHI, KAZUNORI</creatorcontrib><creatorcontrib>NASU, MASARU</creatorcontrib><creatorcontrib>GOTO, JUN</creatorcontrib><creatorcontrib>GOTO, YOUICHIRO</creatorcontrib><creatorcontrib>SHIGENO, HIDEAKI</creatorcontrib><creatorcontrib>ITO, MORIO</creatorcontrib><creatorcontrib>MIYAKO, HIROSHI</creatorcontrib><creatorcontrib>SUGAWARA, KOUICHI</creatorcontrib><creatorcontrib>SAITOU, ATSUSHI</creatorcontrib><creatorcontrib>KUSANO, NOBUCHIKA</creatorcontrib><creatorcontrib>IGARI, JUN</creatorcontrib><title>SUSCEPTIBILITY OF BACTERIA ISOLATED FROM THE PATIENTS WITH LOWER RESPIRATORY TRACT INFECTIONS TO ANTIBIOTICS (1986)</title><title>Japanese journal of antibiotics</title><addtitle>Jpn.

The following is a report of the 1986 findings. During the period from September, 1986 to March, 1987, 558 cases of respiratory infections were reported at 17 institutions across the nation and a total of 657 apparent causative strains were isolated from sputum samples. Of these strains, 75 strains of Staphylococcus aureus, 108 of Streptococcus pneumoniae, 150 of Haemophilus influenzae, 107 of Pseudomonas aeruginosa (non-mucoid production type), 21 of P. aeruginosa (mucoid production type), 32 of Klebsiella pneumoniae, 8 of Escherichia coli, and 55 of Branhamella catarrhalis were subjected to MIC determination of various antibacterial and antibiotic agents to map drug sensitivities. In addition, diagnoses, age distributions by diagnoses, frequencies of infectious diseases, types of isolated bacteria, and usage statuses of the antibacterial and antibiotic agents the times of at isolation were also investigated. MIC determinations were carried out to investigate susceptibilities of causative organisms of respiratory tract infections to various antibacterial and antibiotic agents. From the 558 cases of respiratory tract infections, 657 strains were detected at concentrations not less than 104-6/ml and identified to be the causative organisms. Of these strains, 603 could be used for MIC determination. An overwhelming majority of major causative bacteria, inclusive of H. influenzae and S. pneumoniae, showed sensitivity patterns similar to the sensitivity patterns found a year earlier. P. aeruginosa alone, however, showed some increase in its susceptibility to penicillin and cephem antibiotics. Regarding patient backgrounds, the age distribution was heavily biased towards the higher end of the scale, which patients with ages of 50 or higher accounting for 77.9%, compared to 73.5% in 1985. When the patients were classified by diagnoses, chronic bronchitis, bacterial pneumonia and bronchiectasis accounted for the majority of the infections: 28.7%, 23.3%, and 19.0%, respectively. The percentages of chronic bronchitis and bacterial pneumonia 28.7% and 23.3%, respectively, were somewhat higher in 1986 than in 1985. The disease which was comparatively frequent in all age groups was bronchiectasis, which accounted for 44.0% in patients with ages 29 years or lower, 18.4% in patients between 30 years and 69 years, and 16.7% in patients with ages 70 years or higher. The next most frequent infection was bacterial pneumonia. Another finding of note was that whereas acute bronchitis was more frequent among young patients, chronic bronchitis was more prevalent in elderly patients. When classified by diagnoses, H. influenzae, P. aeruginosa, and S. pneumoniae were frequent in most infectious diseases. Of 355 strains isolated from patients with chronic bronchitis, diffuse panbronchiolitis or bronchiectasis, P. aeruginosa, H. influenzae, and S. pneumoniae accounted for 27.9%, 26.2%, and 18.0%, respectively. However, the incidence of H. influenzae has been declining yearly, while the frequencies of P. aeruginosa and S. pneumoniae are increasing. It is noteworthy that the includence of B. catarrhalis is on a slow but steady increase. In cases of bacterial pneumonia, the frequency of S. aureus was comparatively high.</abstract><cop>Japan</cop><pub>Japan Antibiotics Research Association</pub><pmid>2695657</pmid><doi>10.11553/antibiotics1968b.42.2324</doi><tpages>30</tpages><oa>free_for_read</oa></addata></record> |
