Identification of the difference between viruses, fungi, bacteria and parasites
Bacteria.
Bacteria refer to the smallest living and non-living organism that multiply by
themselves. Bacteria can be useful and
dangerous for health as they spread infection and diseases and generally
treated with antibiotics.
Virus.
Viruses are made up of protein and genes that spread throughout the body by
invading the body cells to increase their growth. The virus spread from human
to human, and the treatment of viral disease is not much useful.
Fungi.
Fungi grow in moist and warm places, and harmful for human bodies such as
coughing, itching, and wheezing. Some fungi are used for the human body such as
penicillin.
Parasites.
Parasites need another organism for their survival and cause pathogenic
parasites.
Role of viruses, fungi, bacteria, and parasites in spreading infection and illness
Bacteria.
Tuberculosis, bronchitis, gonorrhoea, food poisoning, coccidiosis, MRSA, salmon
losses, strep throat/tonsils, syphilis, and Chlamydia.
Virus.
Common cold, ear infection, influenza, pneumonia, HIV/AIDS, dengue, herpes,
West Nile Virus, warts encephalitis.
Fungi.
Valley fever, yeast infection ringworm, athlete's foot.
Parasites.
Worms, malaria, (trypanosomiasis), schistosomiasis, sleeping sickness, and
leishmaniasis.
Colonisation and infection
Infection
refers to the invasion of the body tissues due to disease and results in a
microorganism.
Colonisation
refers to the multiplication or growth of microorganism without the invasion of
body tissues (Ritchie, Sanderson, Kilbane, & Routledge, 2003).
Systematic infection vs localised infection
The
systematic infection refers to the infection breakout, within the whole body
through bloodstreams such as Septicaemia. Whereas localized infection means
that, the virus has a breakout within the specific parts of the body such as
ulcer and particular cut (Sanderson, Kennedy, Ritchie, and Goodwin, 2002).
Poor practices and development of infectious diseases
The
poor practices that may lead to spread of disease are not wearing the personal
hygienic clothes, not washing your hands, not covering your nose and mouth, and
not clearing your surrounded area (Ritchie, Sanderson, Kilbane, &
Routledge, 2003).
How poor practices can help in ons's professional practice
The
understanding of poor practices can be applied to own profession practices by
the self-evaluation process. The duty of mine as a professional is to ensure
that the if I am following the practices related to hygiene condition
appropriately, such as washing hands before and after completing tasks, know
how to use PEE, my hygiene is appropriate, nails are trimmed, and hairs are
neat.
Conditions needed for the progression of micro-organism
The
bacteria probably grow in moist, dark and warm areas with the neutral PH
balance. The protein and sugar are the food for their survival and growth. The
time they need to grow is 4 hours on average. Unfortunately, the human body is
the most optimal place for bacterial growth. In the human body, many cranial
and nooks are dark and full of sweat. Therefore these are needs to be clean for
reducing the risk of infection (Ritchie, Sanderson, Kilbane, & Routledge,
2003).
How the infective agent enter in human body
The
primary pathways for an ineffective agent to enter in the human bodies are a
digestive system, skin break, and respiratory system. There are some other
means for these agents to enter into human organs such as genital tracts, and
conjunctiva.
Common Sources of infections
The
infection diseases are alarming for human bodies, and there are several sources
of infection, among them the most common are listed below.
• Poor hand hygiene
• The already infected
• PPE workplace/uniform
• Cupboard, wall, floor and other surface
area
• Equipment not used or sterilised
appropriately
The ways by which infective agents can be transmitted to the body
The
infected agent transmits to a person through bites from animals and insects.
Some infectious diseases may transmit from one person to another person through
transplacental transmission (pregnant women to the fetus) and touch, kissing,
biting or sexual intercourse. Person to person transmission of infection is
called direct transmission. The infectious diseases may transmit to the human
body through indirect transmissions such as ingestion of contaminated water and
food (Ritchie, Sanderson, Kilbane, & Routledge, 2003).
Factors that might increase the risk of infections
The
risk factors that increase the likeliness of the disease are
• Malnutrition
• Age
• Obesity
• Poor hygienic condition
• Skin integrity
• Skinfold
