Biochemical Test – Enterobacteriaceae Bacterial spp incapable of fermenting glucose cannot utilize lactose. 2 enzymes necessary for a bacterium to take up lactose: A. β-galactoside permease – facilitates the entry of lactose molecules to bac cell wall B. β-galactosidase – breaks down lactose into β-D glucose and β-D galacatose LF possess both enzymes NLF do not possess β-galactosidase LLF do not possess β-galactoside permease Glucose fermenters only (true enteric pathogen)

The study of shelf life for liquid biofertilizer from vegetable waste showed that contrary to the traditional advice that liquid biofertilizers produced from fermentation by effective microorganisms‚ should be used within three months of production‚ the liquid biofertilizer produced from vegetable waste still contains high amount of viable microbial population after four months of storage with no significant effect of the presence or absence of light (Ngampimol and Kunathigan‚ 2008).

Urinary tract infections refer to the presence of pathogenic microorganisms within the urinary tract and its classification is usually done on the basis of infection sites:-bladder [cystitis]‚ kidney [pyelonephritis]‚ or urine [bacteriuria] and also can be asymptomatic or symptomatic (Quigley R 2009‚ Schlager TA2001). They are among the most commonly acquired bacterial infections and they account for an estimated 25-40% of the nosocomial infections (Bagshaw SM‚ Laupland KB 2006). Urinary tract infection

In this essay‚ I am going to discuss traditional and contemporary wound dressings and management techniques. I will be comparing the traditional dressings with today’s current modern dressing. When choosing a dressing many circumstances have to be accessed as what type of wound is it?

When a wound is healing
