Study Notes

Bacterial Diseases

Salmonella food poisoning is transmitted through bacteria in contaminated food, especially when prepared in unsanitary conditions.
In the UK, vaccination of poultry against Salmonella helps reduce its transmission.
Symptoms of Salmonella infection include fever, abdominal cramps, vomiting, and diarrhea.
Gonorrhoea is an STD characterized by thick yellow or green discharge and painful urination, caused by a bacterium.
Initially treatable with penicillin, many Gonorrhoea strains have developed antibiotic resistance.
Transmission occurs through sexual contact, and control measures include antibiotic treatment and barrier contraception methods.

Fungal Diseases

Rose black spot, caused by a fungus, manifests as purple or black spots on leaves, leading to early leaf drop and reduced photosynthesis.
Spread by water or wind, it can be managed with fungicides and removal of infected leaves.

Protist Diseases

Malaria is caused by protists, specifically Plasmodium, which have a life cycle involving mosquitoes.
Symptoms of malaria include recurrent fever, with the disease potentially being fatal.
Control methods include preventing mosquito breeding and using nets to avoid bites.

Malaria Infection Cycle

Female mosquitoes acquire Plasmodium from infected humans.
Infected mosquitoes inject Plasmodium into another human's bloodstream, where it travels to the liver, multiplies, and then infects red blood cells.
Bursting of infected red blood cells releases more Plasmodium and toxins, leading to malaria symptoms.
Untreated individuals can experience severe illness or mortality.

Vaccine Immunity

Widespread vaccination leads to a significant reduction in pathogen spread.
Vaccination involves introducing dead or inactive pathogens to stimulate antibody production in white blood cells.
Example: MMR vaccine protects against measles, mumps, and rubella.

Antibiotic Resistance

Bacteria can mutate and develop resistance to antibiotics, allowing resistant strains to proliferate.
The rise of resistant bacteria poses a challenge as they can reproduce rapidly without competition.
Strategies to combat resistance include prudent antibiotic prescription and completing prescribed courses to eliminate residual bacteria.

Scientific Efforts

Researchers aim to develop new antibiotic classes and retain some antibiotics for emergency use.

Epidemics and Pandemics

Epidemics are localized outbreaks of disease within one country, while pandemics spread across multiple countries.

Pathogens

Pathogens are microorganisms causing infectious diseases, with harmful effects occurring when they enter the body in large quantities.
Not all bacteria are harmful; pathogenic strains can reproduce quickly and produce toxins.

Viruses

Viruses are smaller than bacteria, and all are pathogens that damage host cells during replication.
Viral invasion involves entering a cell, using its machinery for reproduction, and causing cell damage upon exit.

Mosquito Life Cycle Disruption

Control measures include draining stagnant water, using insecticides to eliminate adult mosquitoes, and oiling water sources to suffocate larvae.

White Blood Cells

White blood cells defend against pathogens through phagocytosis, producing antitoxins, and generating specific antibodies.
Phagocytosis involves engulfing and digesting pathogens, while antibodies target specific bacteria for destruction.

Drug Treatment for Diseases

Painkillers may relieve symptoms but do not kill pathogens; antibiotics effectively eliminate bacteria but are ineffective against viruses.
Developing antiviral drugs poses challenges due to potential damage to host tissues.
Targeting specific bacteria with appropriate antibiotics has decreased mortality from bacterial infections.
