The knowledge of the diversity of strains of Mycobacterium tuberculosis complex (MTBC) species in a specific geographical region can contribute to the control of tuberculosis (TB). This study was conducted to identify the MTBC isolates to the species and spoligotype international type (SIT) level by spoligotyping. A total of 168 MTBC isolates were recovered from TB patients, spoligotyped, and t...

BACKGROUND Nigeria has the tenth highest burden of tuberculosis (TB) among the 22 TB high-burden countries in the world. This study describes the biodiversity and epidemiology of drug-susceptible and drug-resistant TB in Ibadan, Nnewi and Abuja, using 409 DNAs extracted from culture positive TB isolates. METHODOLOGY/PRINCIPAL FINDINGS DNAs extracted from clinical isolates of Mycobacterium tub...

Pure C-phycocyanin (C-PC) was isolated from Arthronema africanum to evaluate its potential antitumor effects in vivo and in vitro. Experimental myeloid Graffi tumor in hamsters was used as a model. The cell proliferation assay showed that C-PC treatment, at concentration of 100 μg mL for 24 h, significantly inhibited the growth of Graffi tumor cells (51.4% viability). Agarose gel electrophoresi...

Mycobacterium tuberculosis rapidly reduces nitrate, leading to the accumulation of nitrite. This characteristic served for the past 40 years to differentiate M. tuberculosis from other members of the Mycobacterium tuberculosis complex (MTBC), such as Mycobacterium bovis (non-BCG [referred to here as simply "M. bovis"]), Mycobacterium bovis BCG, Mycobacterium africanum, or Mycobacterium microti....

Consumption of pine needles tends to cause abortion in domestic cattle but not in elk. The present study was undertaken to determine whether this difference was associated with the rumen microbial population. After emptying the rumen, pregnant cattle were inoculated with either elk or cattle rumen contents. For those cows fed the pine needle diet, there was no difference in abortion rate betwee...

Morphometrics of 23 United States populations of Xiphinema americanum sensu lato, sharing the characteristics of an offset lip region and conoid tail, were examined and analyzed statistically by canonical discriminant analysis (CDA). Specimens were collected from Arkansas, Georgia, Tennessee, Mississippi, Florida, Oklahoma, California, and North Dakota. Eleven measurements and body ratios obtai...

The current study manifested that the aqueous flower extract of Peltophorum pterocarpum contain bioactive compounds, is found to be responsible for bioreduction during the synthesis of silver nanoparticles The synthesis of silver nanoparticles occurred under the exposure of the flower extract to 1mM silver nitrate aqueous solution .During this process the complete reduction was observed nearly ...

The aim of the present investigation is to study different pollen parameters such as shape, size, colpa and exine ornamentation for the taxonomic assessment of the groups of plants. The pollen morphology of some plant taxa of the family Fabaceae growing in the area of Arambagh of Hooghly district, West Bengal, India were studied using light microscopy (LM) and scanning electron microscopy (SEM)...

A study in 2010 reported that administration of 2 g of O. sanctum leaves for 30 days to laboratory male albino rabbits showed adverse effect on sperm count and male hormones. The dose and duration at which this testing was reported was commented upon as being high. It is learnt that basis this publication a few European regulators have imposed restrictions on usage of O. sanctum. Recognizing th...
