Infectious diseases

General description of infectious diseases. Infectious diseases spread rapidly, causing great damage to farmers and have microbial, viral, and fungal origin.

Infections are all diseases of humans and animals that are caused by pathogenic microorganisms. Infection (lat. Infectio - I am infected) is a condition of infection that is caused by the interaction between a pathogenic microorganism and an animal (macro).

Economic losses. Unless preventive and other measures are taken on time, infectious diseases can cause significant economic damage.

They are:

a) direct losses from falling animals;

b) loss caused by reduced productivity of animals;

c) Decrease in sales of animals and animal feed (in some cases it is forbidden to sell sick animal products).

The economic damages caused by the most common infectious diseases of bovine animals are listed in the table below.

The economic damages of some infectious diseases.

Table

Infectious diseases	Percentage of patients in disadvantaged herds (community)	Percentage	Specific amount of food reduction per capita
Infectious diseases		Percentage	Food Title	Quantity per liter/kg
Aphthae epizooticae	91 %	1.5 %	Milk	113 liter
Gangraena emphysematosa	1.3 %	70 %	Meat	67 kg
Brucellosis	48 %	-	Milk	675 liter
Tuberkulosis	72 %	-	Milk	630 liter
Anthrax	1.2 %	78 %	Meat	115 kg
Pasteurellosis	42 %	17 %	Meat	8 kg
Trichophytosis	53 %	-	Meat	5 kg

A community that is susceptible to disease (germs, viruses, fungi, parasites or parasitic eggs) is considered unsafe and animals are at high risk of becoming infected.
