There is no specific vaccine against or treatment for exanthema subitum, and most children with the disease are not seriously ill.

Most cases of HHV-6 infection get better on their own. If encephalitis occurs ganciclovir or foscarnet may be useful.

No treatment exists for the viral infection. Antibiotics may help prevent secondary infections.

Vaccination is available in different forms, usually for naive flocks.

Good biosecurity measures should be maintained including adequate quarantine, isolation, separation of different age groups and disinfection.

Outbreaks of zoonoses have been traced to human interaction with and exposure to animals at fairs, petting zoos, and other settings. In 2005, the Centers for Disease Control and Prevention (CDC) issued an updated list of recommendations for preventing zoonosis transmission in public settings. The recommendations, developed in conjunction with the National Association of State Public Health Veterinarians, include educational responsibilities of venue operators, limiting public and animal contact, and animal care and management.

Derzsy's disease is caused by a virus from the Parvoviridae family. It affects geese and Muscovy ducks.

The virus is shed in the faeces and thus transmission is horizontal, via the direct faecal-oral route and also indirectly via fomites. Vertical transmission is also possible.

Clinical disease only occurs in young geese and ducks between birth and 4–5 weeks of age.

Infections are treated with antibiotics, particularly doxycycline, and the acute symptoms appear to respond to these drugs.

A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions)

attach to and enter susceptible cells.

No serious long-term effects are known for this disease, but preliminary evidence suggests, if such symptoms do occur, they are less severe than those associated with Lyme disease.

The most significant zoonotic pathogens causing foodborne diseases are , "Campylobacter", "Caliciviridae", and "Salmonella".

In 2006, a conference held in Berlin was focusing on the issue of zoonotic pathogen effects on food safety, urging governments to intervene, and the public to be vigilant towards the risks of catching food-borne diseases from farm-to-dining table.

Many food outbreaks can be linked to zoonotic pathogens. Many different types of food can be contaminated that have an animal origin. Some common foods linked to zoonotic contaminations include eggs, seafood, meat, dairy, and even some vegetables. Food outbreaks should be handled in preparedness plans to prevent widespread outbreaks and to efficiently and effectively contain outbreaks.

Cat flu is the common name for a feline upper respiratory tract disease. While feline upper respiratory disease can be caused by several different pathogens, there are few symptoms that they have in common.

While Avian Flu can also infect cats, Cat flu is generally a misnomer, since it usually does not refer to an infection by an influenza virus. Instead, it is a syndrome, a term referring to the fact that patients display a number of symptoms that can be caused by one or more of the following infectious agents (pathogens):

1. Feline herpes virus causing feline viral rhinotracheitis (cat common cold, this is the disease that is closely similar to cat flu)

2. Feline calicivirus—(cat respiratory disease)

3. "Bordetella bronchiseptica"—(cat kennel cough)

4. "Chlamydophila felis"—(chlamydia)

In South Africa the term cat flu is also used to refer to Canine Parvo Virus. This is misleading, as transmission of the Canine Parvo Virus rarely involves cats.

Viral disease is usually detected by clinical presentation, for instance severe muscle and joint pains preceding fever, or skin rash and swollen lymph glands.

Laboratory investigation is not directly effective in detecting viral infections, because they do not themselves increase the white blood cell count. Laboratory investigation may be useful in diagnosing associated bacterial infections, however.

Viral infections are commonly of limited duration, so treatment usually consists in reducing the symptoms; antipyretic and analgesic drugs are commonly prescribed.

No specific treatment is available, but antibiotics can be used to prevent secondary infections.

Vaccines are available (ATCvet codes: for the inactivated vaccine, for the live vaccine; plus various combinations).

Biosecurity protocols including adequate isolation, disinfection are important in controlling the spread of the disease.

Some ways to prevent airborne diseases include washing hands, using appropriate hand disinfection, getting regular immunizations against diseases believed to be locally present, wearing a respirator and limiting time spent in the presence of any patient likely to be a source of infection.

Exposure to a patient or animal with an airborne disease does not guarantee receiving the disease. Because of the changes in host immunity and how much the host was exposed to the particles in the air makes a difference to how the disease affects the body.

Antibiotics are not prescribed for patients to control viral infections. They may however be prescribed to a flu patient for instance, to control or prevent bacterial secondary infections. They also may be used in dealing with air-borne bacterial primary infections, such as pneumonic plague.

Additionally the Centers for Disease Control and Prevention (CDC) has told consumers about vaccination and following careful hygiene and sanitation protocols for airborne disease prevention. Consumers also have access to preventive measures like UV Air purification devices that FDA and EPA-certified laboratory test data has verified as effective in inactivating a broad array of airborne infectious diseases. Many public health specialists recommend social distancing to reduce the transmission of airborne infections.

They are treated with antiprotozoal agents. Recent papers have also proposed the use of viruses to treat infections caused by protozoa.

Lymphoid leucosis is a disease that affects chickens, caused by the retrovirus "Avian leukosis virus".

It is a neoplastic disease caused by a virus, which may take the form of a tumor of the bursa of Fabricius and may metastasize to other tissues of the chicken and cause enlargement and swelling of the abdomen.

An airborne disease can be caused by exposure to a source: an infected patient or animal, by being transferred from the infected person or animal’s mouth, nose, cut, or needle puncture. People receive the disease through a portal of entry: mouth, nose, cut, or needle puncture.

One study using the medicinal plant "Peganum harmala" showed it to have a lifesaving effect on cattle infected with East Coast fever.

The classical treatment with tetracyclines (1970–1990) cannot provide efficiency more than 50%.

Since the early 1990s, buparvaquone is used in bovine theileriosis with remarkable results (90 to 98% recovery).

Other than the buparvaquones, other chemotherapeutic options are the parvaquones, e.g. Clexon. Halofuginone lactate has also been shown to have an 80.5% efficacy against "Theirelia parva parva" infections. The ultimate factor that causes death is pulmonary edema.

In May 2010, a vaccine to protect cattle against East Coast fever reportedly had been approved and registered by the governments of Kenya, Malawi and Tanzania. This consists of cryopreserved sporozoites from crushed ticks, but it is expensive and can cause disease.

Control of the disease relies on control of ticks of domestic animals, particularly disease-resistant ticks. This is a major concern in tropical countries with large livestock populations, especially in the endemic area. Pesticides (acaricides) are applied in dipping baths or spray races, and cattle breeds with good ability to acquire immune resistance to the vector ticks are used.

Flacherie (literally: "flaccidness") is a disease of silkworms, caused by silkworms eating infected or contaminated mulberry leaves. Flacherie infected silkworms look weak and can die from this disease. Silkworm larvae that are about to die from Flacherie are a dark brown.

There are two kinds of flacherie: essentially, infectious (viral) flacherie and noninfectious ("bouffee") flacherie. Both are technically a lethal diarrhea.

Bouffée flacherie is caused by heat waves ("bouffée" means "sudden heat spell" in French).

Viral flacherie is ultimately caused by infection with "Bombyx mori" infectious flacherie virus (BmIFV, Iflaviridae), "Bombyx mori" densovirus (BmDNV, Parvoviridae) or "Bombyx mori" cypovirus 1 (BmCPV-1, Reoviridae). This either alone or in combination with bacterial infection destroys the gut tissue. Bacterial pathogens contributing to infectious flaccherie are "Serratia marcescens", and species of "Streptococcus" and "Staphylococcus" in the form known as thatte roga.

Louis Pasteur, who began his studies on silkworm diseases in 1865, was the first one able to recognize that mortality due to viral flacherie was caused by infection. (Priority, however, was claimed by Antoine Béchamp.) Richard Gordon described the discovery: "The French silk industry was meanwhile plummeting from a 130 million to an 8 million francs annual income, because the silkworms had all caught "pébrine," black pepper disease…He [Pasteur] went south from Paris to Alais, and rewarded them by discovering the silkworm epidemic to be inflicted by some sort of living microbe…Pasteur threw in another disease, "flâcherie," silkworm diarrhoea. The cures for both were culling the insects which showed the peppery spots — the peasants bottled the silkworm moths in brandy, for display to the experts — and rigorous hygiene of the mulberry leaf."

The acute symptoms of contagious equine metritis include acyine inflammation of the uterus, an obvious thick, milky, mucous vulvar discharge 10 to 14 days after a live covering by a stallion. Chronic symptoms include milder uterine inflammation that will cause less obvious vulvar discharge, and then the infection may be more difficult to eliminate. Carrier mares can occur once the bacteria become stable within the reproductive tract. These mares can be asymptomatic for months and still remain infectious.

The first case of CEM was diagnosed in England in 1977. It has infected horses in 26 countries:

Austria, Belgium, Bosnia-Herzegovina, Croatia, the Czech Republic, Denmark, Finland, France, Germany, Great Britiain, Greece, Guinea-Bissau, Ireland, Italy, Japan, Luxembourg, the Republic of Macedonia, Montenegro, the Netherlands, Norway, Serbis, the Slovak Republic, Slovenia, Sweden, Switzerland, and the United States.

Mouth actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla.

Actinobacillosis is a zoonotic disease caused by Actinobacillus.

It is more commonly associated with animals than with humans.

One of the most common forms seen by veterinarians is mouth actinobacillosis of cattle, due to "Actinobacillus lignieresii". The most prominent symptom is the swelling of the tongue that comes out of the mouth and is very hard at palpation ("wooden tongue").

"Actinobacillus suis" is an important disease of pigs of all ages and can lead to severe morbidity and sudden death.

Equine venereal diseases are sexually transmitted infections in horses. They include contagious equine metritis (CEM) (caused by "Taylorella equigenitalis") and equine coital exanthema (caused by equine herpesvirus 3).

African histoplasmosis is an infection caused by "Histoplasma duboisii". Disease has been most often reported in Uganda, Nigeria, Zaire and Senegal. In human disease it manifests differently than histoplasmosis (caused by "Histoplasma capsulatum"), most often involving the skin and bones and rarely involving the lungs.

Symptoms include enlargement of abdomen, bursa, weight loss, weakness and emaciation, and depression. The disease is more likely to affect chicken around five to eight months of age who are more vulnerable. Green diarrhea tends to develops at the terminal stage.

Avian infectious bronchitis (IB) is an acute and highly contagious respiratory disease of chickens. The disease is caused by avian infectious bronchitis virus (IBV), a coronavirus, and characterized by respiratory signs including gasping, coughing, sneezing, tracheal rales, and nasal discharge. In young chickens, severe respiratory distress may occur. In layers, respiratory distress, nephritis, decrease in egg production, and loss of internal (watery egg white) and external (fragile, soft, irregular or rough shells, shell-less) egg quality are reported.
