Random Amplification of Polymorphic DNA Based Typing of Pseudomonas Aeruginosa

Microbial Ecology: Where are we now?

Conventional microbiological methods have been readily taken over by newer molecular techniques due to the ease of use, reproducibility, sensitivity and speed of working with nucleic acids. These tools allow high throughput analysis of complex and diverse microbial communities, such as those in soil, freshwater, saltwater, or the microbiota living in collaboration with a host organism (plant, mouse, human, etc). For instance, these methods have been robustly used for characterizing the plant (rhizosphere), animal and human microbiome specifically the complex intestinal microbiota. The human body has been referred to as the Superorganism since microbial genes are more numerous than the number of human genes and are essential to the health of the host. In this review we provide an overview of the Next Generation tools currently available to study microbial ecology, along with their limitations and advantages.

Microscopic characterization of Pseudomonas Aeruginosa confines separate from clinical cases by testing RAPD-PCR method

Pseudomonas Aeruginosa is one of the leading opportunistic infectious agents especially in immune-suppressed patients such like burn victims. Carbapenems like Imipenem (IMP) and Meropenem (MEM) are the choice antimicrobial drugs, which used in the treatment of Penicillin and Aminoglycoside-resistant Pseudomonas Aeruginosa isolates. Based on the importance of the detection of infectious source and their resistance transfer algorithm have a main effect on the control of nosocomial infections this study designed for to consider the antibiotic sensitivity and the genetic pattern of Pseudomonas Aeruginosa isolate in burned patients hospitalized in Ghotbeddin Shirazi Hospital with RAPD-PCR technique. According to the Antibiogram results, the most sensitivity was related to the Gentamicin with 50% while the most resistant related to the Nalidixic Acid, Erythromycin, and Cefotaxime with 90% resistant to all. With RAPD-PCR technique used primers 272, 277 and 287 were detected 18, 15, and 11 algorithms respectively. RAPD-PCR is a genotyping method with a high efficiency and good for the study of bacterial epidemiology and polymorphism.
