The convergence of nanotechnology with microbiology is a nifty interdisciplinary research area that could amplify the limits of technology, enhance global health through formation of different drugs that can be effective against different infectious diseases, and for treatment of drinking water to kill the pathogens and make it safe for public use. Bacteria, fungi, actinomycetes, and plants have been successfully used for the formation of nanoparticles of silver, gold, zinc, etc. As the microorganisms, especially bacteria, are becoming resistant to the commonly used antibiotics, an alternative antimicrobial agent that can be effective against the antibiotic-resistant bacteria is needed. In the present chapter, the author highlights the relationship between these two mighty disciplines. The chapter deals with many aspects like antimicrobial activity of nanoparticles, formation of nanoparticles using microorganisms, etc. The green synthesis of nanoparticles is emerging as a new field of science; hence, it is discussed in detail.

In present investigation, the bacteriological analysis and antibiotic sensitivitypattern of drinking water samples collected from different sources ofAkungba Ã¢â‚¬ÂAkoko, Nigeria was done. The antibiotics mainly considered in ourstudy for determining the sensitivity were amongst the commonly used inthis area for treatment of infectious diseases. As a result, the bacteriologicalindex, especially coliform count was observed notably high with 72 x10 1 cfu/ml for stream sample and 26.4 x 10 1 cfu/ml for borehole sample. The majorbacterial isolates identified in the water samples were Staphylococcus sp,E.coli  Ã¢â‚¬Ânegative bacteria wereobserved showing 75% and 65% resistant to Septrin and Amoxicillin respectively.Also, multiple drug resistance was observed for many antibiotics.Therefore, the presence of high amount antibiotic resistant bacteria of clinicalimportance is reported in these water sources which are usually consumedby students and members of the University community. Hence, thisstudy necessitates the need for water treatment so that epidemics of waterbornebacterial disease can be averted in this region., Klebsiella sp, Pseudomonas sp., Enterococcus sp., Bacillus cereus andothers. With regards to the antibiotic sensitivity test, all isolates showed100% resistance to Ampicillin and Cloxacillin and 85.7% resistance to Zinnacef[a cephalosporin product]. However, the gram

Abstract Acne is a common skin affliction that involves excess sebum production and modified lipid composition, duct blockage, colonization by bacteria, and inflammation. Acne drugs target one or more of these steps, with antibiotics commonly used to treat the microbial infection for moderate to severe cases. Whilst a number of other acne therapies are purported to possess antimicrobial activity, this has been poorly documented in many cases. We conducted a comparative analysis of the activity of common topical acne drugs against the principal etiological agent associated with acne: the aerotolerant anaerobic Gram-positive organism Propionibacterium acnes (recently renamed as Cutibacterium acnes). We also assessed their impact on other bacteria that could also be affected by topical treatments, including both antibiotic-sensitive and antibiotic-resistant strains, using broth microdilution assay conditions. Drugs designated specifically as antibiotics had the greatest potency, but lost activity against resistant strains. The non-antibiotic acne agents did possess widespread antimicrobial activity, including against resistant strains, but at substantially higher concentrations. Hence, the antimicrobial activity of non-antibiotic acne agents may provide protection against a background of increased drug-resistant bacteria.
