Metode: Studi molekuler dilakukan untuk mengidentifikasi alel mutan dua gen yang berhubungan dengan resistensi klorokuin pada isolat P. falciparum di Sumatera Selatan. Sebanyak 25 pasien diambil darahnya, kemudian dilakukan isolasi DNA. Susunan dari kedua gen (Plasmodium falciparum chloroquine resistance transporter/pfcrt dan Plasmodium falciparum multidrug resistance/pfmdr1) dianalisis dengan ...

Polymerase chain reaction-based replicon typing represents a novel method to describe the dissemination and follow the evolution of resistance plasmids. We used this approach to study 26 epidemiologically unrelated Enterobacteriaceae and demonstrate the dominance of incompatibility (Inc) A/C or Inc N-related plasmids carrying some emerging resistance determinants to extended-spectrum cephalospo...

Thirty one of 60 consecutive isolates of Streptococcus faecalis produced a reaction in both D and G streptococcal grouping sera. A close correlation was found between this grouping reaction and haemolysin production, resistance to erythromycin, tetracycline, and trimethoprim, and delayed fermentation of sorbitol.

the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...

background and aims: the indiscriminate use of antibiotics can lead to antibiotic resistance in the treatment of infections caused by bacteria such as pseudomonas aeruginosa. the presence of integrons in pseudomonas is clearly associated with multidrug resistances. therefore, this study aimed at tracking class i, ii and iii integrons of antibiotic-resistant isolates of pseudomonas aeruginosa th...

Doxycycline, a new generation tetracycline antibiotic, is currently one of choice for the treatment and prevention of infections caused by agents of biowarfare. We are developing real time PCR assays to detect tetracycline resistance genes in Gram-negative bacteria. The assay was developed as a multiplex SYBR Green I detection using the Roche Lightcycler and multi-melting peak analysis followed...

This work investigates the effect of Potassium promoter and calcination temperature on catalytic activity in dry reforming methane reaction compares performance Ni, Co, Fe–Al2O3 trimetallic catalysts with reference Ni–Al2O3. Although higher was achieved Ni–Al2O3, resulted a more favorable CO/H2 ratio considerably better coke resistance. Higher led to increase formation which caused sintering ca...
