Nanotechnology based on nanoscale materials is rapidly being used in clinical settings, particularly as a new approach for infectious illnesses. Recently, many physical/chemical approaches utilized to produce nanoparticles are expensive and highly unsafe biological species ecosystems. This study demonstrated an environmentally friendly mode of producing (NPs) where Fusarium oxysporum has been employed generation silver (AgNPs), which were further tested their antimicrobial potentials against...

Metallo-β-lactamases (MBLs) type carbapenemases are produced by pathogenic Pseudomonas spp. and exhibit carbapenemase activity. The study will look into drug resistance the molecular mechanisms of drug-resistant aeruginosa variants. A total 74 P. strains were isolated from urine, pus, sputum, blood, throat swab, Foley's catheter, nasal swab. isolates screened for antibiotic susceptibility identified MDR further tested β-lactamase production. Multiplex PCR was used to identify presence mcr-1...

The carbapenem-resistant Klebsiella pneumoniae poses a serious threat to public health because carbapenems are used as final resort treat K. pneumoniae-mediated infections in humans. Samples were collected from various clinical specimens including skin swabs, anal wound oral and sputum by the standard method strains isolated. Biofilm-forming characters determined. antibiotic resistance pattern was analyzed Kirby–Bauer disk diffusion method. Carbapenem properties tested using imipenem...

Tuberculosis (TB) is one of the leading causes death throughout world. Traditional medicine poses a serious challenge todrug resistance against Mycobacterium tuberculosis. Hence, it an urgent need to develop, novel anti-mycobacterial compounds. In this study, potent compound producing Staphylococcus hominis IS2 was isolated from custard apple exhibiting activity than other isolates. The bacterial strain cultured and purified by combination ammonium sulphate precipitation DEAE-cellulose...

Bifidobacterium represent one of the major genera intestinal tract human and animals used as probiotics in dairy nondairy foods for restore microflora which confers a health benefit. The identification by phenotypic features is commonly unreliable, time, money, effort consuming. We sought to improve method based on molecular level identify probiotic bacteria complex microbial communities. application 16S-23S rRNA oligonucleotide primers best most reliable, rapid, precise species sub...
