It was found that at i/v route of application the concentrations of the antibiotic ranged above 2 micrograms/cm3 within the interval from the 15th min up to the 8h hour. The time of half-distribution (t1/2 alpha) was 0.28 h, while the biologic half-life of half-elimination (t1/2 beta) was 2.31 h. After muscular application of apramycin at 20 and 40 mg/kg it was rapidly adsorbed at the site of injection; the maximum concentrations were 99 micrograms/cm3 and 202 micrograms/cm3, resp., from the first to the second hour. Levels above 2 micrograms/cm3 were found in the blood serum in the course of 8 to 10 hours when the antibiotic was applied at 20 mg/kg b. m., and they have persisted for more than 12 hours when it was administered at the rate of 40 mg/kg. The biologic half-life (t1/2 beta) was 1.63 h and 1.97 h, respectively. Following the oral administration of the antibiotic at 40 mg/kg subtherapeutic levels were established up to the 24 th hour, with the exception of the interval of the 6 th to 8 th when the concentrations were below the minimum therapeutic one (2 micrograms/cm3).(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":23492,"journal":{"name":"Veterinarno-meditsinski nauki","volume":"24 1","pages":"64-71"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14737672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Sensitivity of Salmonellae isolated from poultry to bacteriophage O1].","authors":"M Stefanov, K Kolev, V Stefanov","doi":"","DOIUrl":"","url":null,"abstract":"Studied were a total of 200 bacterial strains that agglutinated with the group B, C, D and E Salmonella sera. The organisms were isolated from viscera (liver, gallbladder, spleen, ovaries, and heart) and bone marrow from dead birds, from embryos, eggs, and washings from hatcheries, etc. in 1982-1985 in the district of Stara Zagora. It was found that the strains behaved biochemically as typical Salmonellae. Serologically typed of group B were 40 strains (S. typhimurium--34, and S. lagos--6); of group C--61 strains (S. oranienburg--38, S. isangi--7, S. montevideo--4, Salmonella II 6.7:gmst: 1.5--5, S. thompson--2, and S. newport--5); of group D--89 strains (S. gallinarum--57, S. gallinarum var. duisburg--23, S. pullorum--1, and S, enteritidis--8); and of group E--8 strains (S. senftenberg--4, S. anatum--4). Two of the strains were in the R form. Sensitive to the phage proved 89 +/- 5.7 per cent of the strains including the two R-form ones and those that were resistant of group C (S. oranienburg--5.4 per cent) and of group D (S. gallinarum--23 per cent, and S. gallinarum var. duisburg--26.1 per cent). The high sensitivity to the phage substantiated the phage identification of the strains as an adjunct, supplementary method in the complex diagnostics of diseases of a Salmonella etiology after the preliminarily determined phage for the respective region was made known.","PeriodicalId":23492,"journal":{"name":"Veterinarno-meditsinski nauki","volume":"24 1","pages":"24-7"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14737732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that blood serum iron dropped abruptly as early as the second day of infection, whereas the level of iron in the liver rose. The erythrocyte count dropped almost twice as early as the second day following infection, the haematocrit value of the blood following the fluctuations of the erythrocyte count. The haemoglobin level dropped considerably on the third day, with gradually lowering values up to the seventh day. All changes that were recorded with these indices of the blood were found to precede the onset of the first clinical signs of the disease. The values of the haematologic indices with birds that survived came back to normal after the fourteenth day of infection. In the author's personal view leading in the pathogenesis of acute typhoid with the New Hampshire chickens was the lowered amount of serum iron, which disturbed the synthesis of haemoglobin and hence the maturity of erythrocytes, substantiating their lower count. The trophism of vitally important organs and tissues was also found to be disturbed.","PeriodicalId":23492,"journal":{"name":"Veterinarno-meditsinski nauki","volume":"24 5","pages":"70-4"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14751336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
