دافنی Daphnia magna یک گونه مرغوب جهت تغذیه ماهیان آب شیرین است. در تحقیق حاضر، تاثیر دوگونه جلبک سبز آبی آنابنافلوس-آکوا (Anabaena flos-aquae) و اسیلاتوریا آفریکانوم (Oscillatoria africanum) بر میزان بلعیدن، نرخ فیلتر کردن و تغذیه دافنی ماگنا (Daphnia magna) مورد بررسی قرار گرفت. آزمایش در سه تکرار و با شرایط یکسان برای هر دو جلبک انجام شد. نرخ فیلتر کردن، بلعیدن و تغذیه دافنی ماگنا از این دو ...
We analyzed DNA polymorphisms in 455 Mycobacterium tuberculosis complex isolates from 455 patients to evaluate the biodiversity of tubercle bacilli in Ouest province, Cameroon. The phenotypic and genotypic identification methods gave concordant results for 99.5% of M. tuberculosis isolates (413 strains) and for 90% of Mycobacterium africanum isolates (41 strains). Mycobacterium bovis was isolat...
In a previous report, we described a PCR protocol for the differentiation of the various species of the Mycobacterium tuberculosis complex (MTC) on the basis of genomic deletions (R. C. Huard, L. C. de Oliveira Lazzarini, W. R. Butler, D. van Soolingen, and J. L. Ho, J. Clin. Microbiol. 41:1637-1650, 2003). That report also provided a broad cross-comparison of several previously identified, phy...
SUMMARY OBJECTIVE Characterize mycobacterial species causing pulmonary tuberculosis (PTB) at the Korle-Bu Teaching Hospital in Ghana. DESIGN Sputum smear positive samples, two (2) from 70 patients diagnosed as having tuberculosis, after they had consented, were collected from the Korle-Bu Teaching Hospital Chest Clinic between January and July 2003. SETTING Korle-Bu Teaching Hospital Chest ...
DNA preparations from 24 New Zealand isolates, two reference strains of Mycobacterium bovis, and one reference strain each of Mycobacterium microti, Mycobacterium africanum, and Mycobacterium tuberculosis were characterized by restriction endonuclease analysis. Twenty-five restriction enzymes were investigated. The clearest differences in M. bovis patterns were obtained with the enzymes BstEII ...
Objective. Data on pulmonary tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) complex in Nigeria are limited. We investigated species of MTB complex in TB cases from northern Nigeria. Methods. New TB suspects were enrolled, screened for HIV and their sputum samples were cultured after routine microscopy. Genotypes MTBC and MTBDRplus were used to characterize the MTB complex species ...
