Viruses are microorganisms , which are living while they are in the host , they make use of host nutrients and enzymes for their own reproduction and growth.
Virus means toxic particle, virus are considered non living things when they are free in the environment in the dormant stage , and become active when the encounter a suitable host.
The example of virus which make use of our body's biochemicals and nutrients for its growth is HIV virus , it make use of human DNA material for its own reproduction. pharmaguideline.
Virus infections are many times difficult to treat as virus exhibit many strains and mutations over the time which is main reason for developing antibiotic and drug resistance.
The main reason why viruses are lethal is that they incorporate its own genetic material in to host cell. this is one of major reason that viruses are associated with many cancer in humans.
Following is the brief list of disease caused by viruses

1. Hepatitis -- Caused by hepatitis B and A virus , Acute hepatitis is mainly caused by Hepatitis A virus
2.AIDS---Caused by HIV
3.Upper respiratory tract infection caused by ---Adenovirus
4.Picorna virus --Causes common cold like condition.
5.Yellow fever caused by yellow fever virus
6.Herpese simplex is caused by Herpeseviridae
7.infulenza is caused by Orthomyxoviridae
8.Rabies ic caused by Rhabdoviridae
9. Mumps is caused by Mumps virus
10. Poliomyletes is caused by polio virus

What is tyndalization
When any material which is pron to be attacked by microorganism is heated for sterilisation, say for 121 degree for 30 minutes , some time it was found that on storage such material again shows microbial growth.
It is the indication that the material might have got sterilised but in storage in favorable condition bacterial spores which are resistant to temperature at which material was sterilised germinate again and give rise to viable microorganisms again.
pharmaguideline.
To counter act this phenomenon , a process was degined where in material is subjected for sterilisation process at 100 deg Celsius for 15 minutes .
Then it is stored for one day , again it is subjected for heating at 100 deg Celsius.
Material is again heated treated till it is boiled normally at 100 deg for 15 minutes.
This process in first day allows spoors to germinate in favourable condition and again material is heated , this step is repeated for two times.
This process is usually used for food processing. pharma .blogspot.com
This process is called as tyndallization after the scientists name John Tyndall who invented the process.

Antibiotic resistance
Antibiotic resistance is a very important factor while choosing an antibiotic against a particular phatogen or disease causing microorganism. After a prolonged or indiscriminate use of an antibiotic microorganism develop mutation in their genetic constitution which make them resistant against toxic action of an antibiotic , there are several mechanisms responsible for acquiring antibiotic resistance in microorganisms like bacteria’s , fungi , viruses etc, it is also termed as drug resitance as antibiotics are used as drugs in treatment of infections. pharmaguideline.
There for a proper antibiotic drug resistance mapping or assay is required to be carried out befor starting a therapy with antibiotics, there is likelihood that after use of an antibiotic over a period of time for treatment or due to cross contamination , it may lead to development of resistance against other antibiotics , such antibiotic resistance developed is called as cross resistance , usually cross resistance occur in same class of antibiotics like betalactum cross resistance will show resistance for other betalactum antibiotic, there for there is special requirements for manufacturing of penicillin group of antibiotics in pharmaceutical companies pharma .blogspot.com

What is Salmonellosis
Salmonellosis
Salmonellosis
It is an infectious disease caused by infection by bacteria Salmonella.
Individual infected with this bacteria Salmonella develop fever , vomiting and diarrhea and abdominal cramps within just 6 hours to three days after getting infection majority of cases disease symptoms lasts for 5 to 8 days and many people’s recover without any treatment by virtue of our bodies protective mechanism. pharmaguideline.
The most sever factor of salmonellosis is diarrhea which may prove sever in some cases if not treated, hence individual infected with salmonella is required to be hospitalized immediately.
They are required to be treated with fluid replenishment treatments to regain fluid loss due to diarrhea, which is given through intravenous saline or a oral dehydration salt preparation is given to patients in case a patient yet to be hospitalized.
Infection of salmonella may spread in blood or other tissue where it may cause serious injuries and may become life threatening. pharma .blogspot.com
