Poem for Aspirants

You have a dream, a noble goal

To clear the exam and make it whole

You study hard, you do your best

But sometimes you feel like you need a rest

You face the challenge, you take the test

But the result is not what you expect

You feel discouraged, you feel dismayed

But you don't let your spirit fade

You try again, you don't give up

You learn from your mistakes and level up

You know that success is not a fluke

But a reward for those who persevere and improve

You have a passion, a fire inside

To achieve your dream and make it shine

You have a vision, a purpose clear

To clear the exam and advance your career

You have the courage, the strength, the will

To overcome the obstacles and climb the hill

You have the hope, the faith, the love

To inspire yourself and others above

You are a fighter, a warrior, a hero

You are a aspirant and you will make it so! 🙌

What are Pathogens and how they invade host ?

What are Pathogens? Pathogens are the organisms which cause disease in living things. For example., Bacteria, viruses, Fungi, protozoa, helminth, parasites etc. How parasites cause harm to host ? Parasites causes harm to the host by living in (or on ) them and multiply in large numbers. For example, Malaria, a disease caused by parasite. How pathogen invade host ? Pathogens enter the body by various places of the body like skin ,mouth, etc and multiply , interfere with normal necessary activities. It results in morphological & functional damage. How Pathogens survive in the body of host ? Pathogens have to adapt to life within the environment of the host. For example., The pathogens that enter the gut must know a way of surviving in the stomach at low pH (1.5 to 3.5) which is acidic in nature. And survive in the presence of digestive enzymes.

Gram staining | History | Application |Principle | Procedure

Gram Stain In 1884, Hans Christian Gram discovered a staining technique that could help to visualise the infectious bacteria clearly and can easily study their morphology. In this technique he used crystal violet (the primary dye), Gram’s iodine (IKI, the mordant), an alcohol rinse (decolorizer), Safranin (counter stain ). A Gram stain is a test that checks for bacteria at the site of a suspected infection such as the throat, lungs, genitals, or in skin wounds. Gram stains may also be used to check for bacteria in certain body fluids, such as blood or urine . This color choice provides differentiation between bacteria that stain purple, called gram-positive, and those that stain red, called gram-negative. The difference between gram-positive and gram-negative bacteria is due to the physical nature of their cell walls and how it reacts to the series of reagents applied to the cells . Gram positive bacteria has thick peptidoglyca...
