What are the effects of disease on animals?
The direct effects of animal diseases on livestock productivity include reduced feed intake, changes in digestion and metabolism, increased morbidity and mortality and decreased rates of reproduction, weight gain and milk production.
How does disease affect animal population?
Disease outbreaks that do not cause direct mortality may also affect populations by reducing reproductive rates (Breed et al., 2009), which can slow a species recovery following a disturbance and make populations more vulnerable to stochastic extinction.
What causes diseases in animals?
Direct causes of disease are: (1) bacteria, (2) viruses, (3) parasites, (4) fungi, (5) nutritional deficiencies, (6) chemical poisons, and (7) unknown causes. Infectious diseases are the greatest threat to livestock health. They are caused by bacteria, viruses, rickettsia and fungi.
What are the effects of diseases?
Symptoms of illness are often not directly the result of infection, but a collection of evolved responses – sickness behavior by the body – that helps clear infection and promote recovery. Such aspects of illness can include lethargy, depression, loss of appetite, sleepiness, hyperalgesia, and inability to concentrate.
How are diseases spread in animals and plants?
They infect a host , reproduce (or replicate themselves if a virus), spread from their host and then infect other organisms. Diseases caused by pathogens are called communicable diseases . This means they can be caught. The spread of communicable diseases is called transmission .
How do diseases affect the ecosystem?
Infectious diseases are a strong force that can affect individual organisms, populations, communities, and ecosystems. Infectious diseases are caused by parasites and pathogens which can impair or even kill its host. Surprisingly, parasites and pathogens are a common and integral part of healthy ecosystems.
How do diseases affect biodiversity?
An ecosystem with lots of variation (genetic diversity and diversity of species) is more resilient to the impacts of disease because there are greater possibilities that some species have evolved resistance, or if a species is lost, there will likely be another species to fill the niche of an extinct species.
How does the environment affect disease?
A number of specific environmental issues can impede human health and wellness. These issues include chemical pollution, air pollution, climate change, disease-causing microbes, lack of access to health care, poor infrastructure, and poor water quality.
Which diseases are caused by bacteria in animals?
People and animals have bacteria living on and in them that do not cause disease. Examples of diseases in animals caused by bacteria are anthrax, blackquarter and tuberculosis. Bacteria can infect wounds, and that is why wounds should be treated.
How many diseases come from animals?
Scientists estimate that more than 6 out of every 10 known infectious diseases in people can be spread from animals, and 3 out of every 4 new or emerging infectious diseases in people come from animals.
How do viruses cause illness?
Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.
How do disease affect plants?
A symptom of plant disease is a visible effect of disease on the plant. Symptoms may include a detectable change in color, shape or function of the plant as it responds to the pathogen. Leaf wilting is a typical symptom of verticilium wilt, caused by the fungal plant pathogens Verticillium albo-atrum and V. dahliae.
What are the effect of disease on crop production?
As agriculture struggles to support the rapidly growing global population, plant disease reduces the production and quality of food, fibre and biofuel crops. Losses may be catastrophic or chronic, but on average account for 42% of the production of the six most important food crops.
