abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

background: previous studies have revealed significant differences between populations for genotypic frequencies of glutathione s-transferase t1 ( gstt1 ) and m1 ( gstm1 ) polymorphisms. in order to find the frequency of the null genotypes of gstm1 and gstt1 in iranian populations, the present study was carried out. methods: the total study subjects consisted of 1340 unrelated healthy muslims/i...

A binary classification system has been established for group A rotaviruses, with the viral capsid protein VP7 defining G types and VP4 defining P types. At least 15 G types and 21 P types have been isolated globally with various G and P combinations. Most of the currently circulating human rotaviruses belong to G1P[8], G2P[4], G3P[8], and G4P[8]. We report a human rotavirus strain (B1711) with...

Accurate co-receptor tropism (CRT) determination is critical for making treatment decisions in HIV management. We created a genotypic tropism prediction tool by utilizing the case-based reasoning (CBR) technique that attempts to solve new problems through applying the solution from similar past problems. V3 loop sequences from 732 clinical samples with diverse characteristics were used to build...

Zymomonas mobilis strains recently isolated from French 'framboisé' ciders were compared with collection strains of the two defined subspecies, Z. mobilis subsp. mobilis and Z. mobilis subsp. pomaceae, using a polyphasic approach. Six strains isolated from six different regions of France were compared with three strains of Z. mobilis subsp. mobilis, including the type strain LMG 404T, and four ...

BACKGROUND Congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. However, there is limited information on detection and genotypic characterization of Toxoplasma gondii (T. gondii) in women with recurrent spontaneous abortion (RSA). The aim of this study is the molecular detection and genotypic characterization of T. gondii in formalin-fixed, paraffin-embedded fetopla...

granulocytic ehrlichiosis in Europe: clinical and laboratory findings for four patients from Slovenia. Use of CRH/he Lyme disease mouse model for the recovery of a Spanish isolate of Borrelia garinii from erythema migrans lesions. To the Editor: Five species of tick-associated rickettsiae have been identified in China; of these, three are human pathogens and two are of unknown pathogenicity (1)...

Twenty-six root nodule bacteria from two native forage legumes namely Sulla aculeolata subsp. and mauritanica were isolated analyzed using a polyphasic approach comprising phenotypic traits, ERIC-PCR, 16S rRNA gene sequencing. This is the first time study has been performed to determine diversity of associated with spp. Phenotypically, all isolates identified as fast-growing shows high toleranc...

conclusions mlva analysis showed that samples obtained from different sources could have similar genetic profile. as a result, administration of penicillin in patients with listeriosis (especially pregnant women) and antibiotic susceptibility test are recommended. the fast and accurate methods such as mlva for tracking of pollution sources of l. monocytogenes are recommended during outbreaks. r...

background and objectives: pneumocystis jiroveci is an important causative agent of pneumocystis pneumonia. during childhood, exposure to pneumocystis occurs and antibody was built in early childhood. the aim of this study was to describe the molecular epidemiology of p. jiroveci in children without any respiratory syndrome and survey the distribution of different mitochondrial large subunit, r...
