Animal diseases

Leprosy, also known as '''Hansen's disease (HD'), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis''. Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. This nerve damage may result in the loss of nociception, which can lead to the loss of parts of a person's extremities from repeated injuries or infection through unnoticed wounds. An infected person may also experience muscle weakness and loss of eyesight. Leprosy symptoms may begin within one year or take 20 years or more.

A zoonosis (; : zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a virus, bacterium, parasite, fungi or prion) which can jump from a non-human animal to a human. When humans infect non-humans, it is called reverse zoonosis or anthroponosis.

Giardiasis is a parasitic disease caused by the protist enteropathogen Giardia duodenalis (also known as G. lamblia and G. intestinalis), especially common in children and travelers. Infected individuals experience steatorrhea, a type of diarrhea with fatty sticky stool; abdominal pain, weight loss, and weakness due to dehydration and malabsorption. Less common symptoms include skin rash, hives and joint swelling. Symptoms usually begin one to three weeks after exposure and, without treatment, may last two to six weeks or longer. Some infected individuals experience mild or no symptoms and rem

Filariasis is a filarial infection caused by parasitic nematodes (roundworms) spread by different vectors. They are included in the list of neglected tropical diseases.

Fusarium (; ) is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. The name of Fusarium comes from Latin fusus, meaning a spindle. Most species in Genus Fusarium are harmless saprobes found in relative abundance in the soil microbial community, and some exist as commensal members of the skin microbiome.

species of worm

Coccidia (Coccidiasina) are a subclass of microscopic, spore-forming, single-celled obligate intracellular parasites belonging to the apicomplexan class Conoidasida. As obligate intracellular parasites, they must live and reproduce within an animal cell. Coccidian parasites infect the intestinal tracts of animals, and are the largest group of apicomplexan protozoa.

Veterinary epidemiology (also known as epizootiology or epizoology) is the branch of epidemiology that studies the frequency, distribution, and determinants of health and disease in animal populations. While human epidemiology focuses on disease in human populations, veterinary epidemiology applies the same principles and methods to domestic animals, livestock, and wildlife, with the goal of preventing, mitigating, or eliminating the impact of disease in susceptible populations. In veterinary practice, epidemiological methods are used not only to enhance animal health but also to improve produ

A panzootic (from Greek παν all + ζόιον animal) is an epizootic (an outbreak of an infectious disease of non-human animals) that spreads across a large region (for example a continent), or even worldwide. The equivalent in human populations is called a pandemic.

This condition is primarily induced by organotin compounds, notably tributyltin (TBT), which have been widely used in antifouling paints for ships to prevent biofouling. Unlike

Encephalitozoonosis is a parasitic disease caused by the microsporidia Encephalitozoon cuniculi, which mainly affects rabbits in Europe. Other strains of the pathogen cause disease in Old World mice and canines. Encephalitozoonosis occurs mainly in immunocompromised animals and is a potential zoonosis. Although very rare, it can also occur in immunocompromised humans. Wright and Craighead first described the disease in 1922. thumb|Encephalitozoonosis with torticollis The pathogen primarily affects the kidneys and brain, causing neurological disorders. The most common symptom is a tilted head.
