Psuedomonas aeruginosa-Associated Acute and Chronic Pulmonary Infections
Pseudomonas aeruginosa is highly successful in colonizing in all types of environments. P. aeruginosa colonizing in adverse environment due to the presence of its virulence factors include production of toxins, proteases hemolysins, and formation of biofilms. In man, the most common opportunist pathogen is P. aeruginosa. Metabolically P. aeruginosa is versatile. Most of the antibiotics targeted metabolically active cells and bacteria could contribute to decrease in biofilm susceptibility to the antimicrobial agents. Scientists suggested about Pseudomonas that it can be catabolized any hydrocarbon in specific time along with availability of oxygen and nitrite. If bacteria are not susceptible to one agent in three or more, it is called as multidrug-resistance strains. The antimicrobial treatments were not suitable when microorganism presented in vitro microorganism resistance to antimicrobials used for treatment of the patient which lack of treatment for 24 h after diagnosis of microbial infections. Bacteria have developed resistance against commonly used antibiotics. Treatment of Pseudomonas infections is coming harder day by day as its resistance against most of the antibiotics. Because of resistance of bacteria antibiotics, alternative methods are in consideration. These methods include use of lactic acid bacteria (LAB) and most recently nano-particles. That is why they are used as antibacterial agents.

Recent Advances in Evaluating Insects as Bioindicators of Heavy Metal Pollution
Natural ecosystems are adversely affected by man-made interventions. Among living organisms, insects are regarded as susceptible to environment disruption as delicate body confirms the presence or absence of polluted environment thus found as suitable indicators of the aquatic and terrestrial ecosystem. Insects are being considered indicators of environmental pollution because different taxa of different localities provide robust information, provide a comparison of various communities, and quantitative data associated with indicators etc. Most of them present the quick reliable influence to heavy metal accumulation as pronounced disruptions were observed at molecular and biochemical level hence considered as best opted indicators of environmental pollution.
