Rabies is a viral disease that causes acute encephalitis
(inflammation of the brain) in warm blooded animals. Rabies is a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by a virus
Polio: flaccid paralysis, major and minor
disease, fecal-oral
Coxsackievirus A: vesicular diseases,
meningitis; coxsackievirus B (body):
pleurodynia, myocarditis
Other echovirus and enteroviruses: like
coxsackievirus
Rhinoviruses: common cold, acid labile, does
not replicate above 33° C
Biology, Virulence, and Disease
• Small size, icosahedral capsid, positive RNA
genome with terminal protein
• Genome is sufficient for infection
• Encodes RNA-dependent RNA polymerase,
replicates in cytoplasm
Enteroviruses
• Capsid virus resistant to inactivation
• Disease due to lytic infection of important
target tissue
• Polio: cytolytic infection of motor neurons of
anterior horn and brainstem, paralysis
• Coxsackievirus A: herpangina, hand-foot-
and-mouth disease, common cold,
meningitis
• Coxsackievirus B: pleurodynia, neonatal
myocarditis, type 1 diabetes
Rhinoviruses
• Acid labile and cannot replicate at body
temperature
• Restricted to upper respiratory tract
• Common cold
Epidemiology
• Enteroviruses transmitted by fecal-oral route
and aerosols
• Rhinoviruses transmitted by aerosols and
contact
Diagnosis
• Immune assays (ELISA) or RT-PCR genome
analysis of blood, CSF, or other relevant
sample
Treatment, Prevention, and Control
• OPV and IPV polio vaccines

icornaviridae is one of the largest families of viruses and
includes some of the most important human and animal
viruses (Box 46-1). As the name indicates, these viruses are
small (pico) ribonucleic acid (RNA) viruses that have a
naked capsid structure. The family has more than 230
members divided into nine genera, including Enterovirus,
Rhinovirus, Hepatovirus (hepatitis A virus; discussed in
Chapter 55), Cardiovirus, and Aphthovirus. The enterovi-
ruses are distinguished from the rhinoviruses by the stabil-
ity of the capsid at pH 3, the optimum temperature
for growth, the mode of transmission, and their diseases
Dogs are the source of the vast majority of human rabies deaths, contributing up to 99% of all rabies transmissions to humans. ... Rabies is an infectious viral disease that is almost always fatal. It is a preventable viral disease of mammals most often transmitted through the bite of a rabid animal. The vast majority of rabies cases reported to the Centers for Disease Control and Prevention (CDC) each year occur in wild animals like raccoons, skunks, bats, and foxes.

Can be seen under light microscope
Poxvirus diseases are characterized by skin lesions – localized or generalized
Important diseases caused by poxviruses are-
Smallpox
Monkeypox
Cowpox
Tanapox
Molluscum contagiosum
The Paramyxoviridae is a family of single-stranded RNA viruses known to cause different types of infections in vertebrates. Examples of these infections in humans include the measles virus, mumps virus, parainfluenza virus, and respiratory syncytial virus (RSV).
Adenoviridae is a group of medium sized, non-enveloped, double stranded DNA viruses that replicate and produce disease in the eye and in the respiratory, gastrointestinal and urinary tracts;
Poxviruses are brick or oval-shaped viruses with large double-stranded DNA genomes. Poxviruses exist throughout the world and cause disease in humans and many other types of animals. Poxvirus infections typically result in the formation of lesions, skin nodules, or disseminated rash.

Diagnosis and Treatment of Canine Pyodermaupstatevet
Ed Jazic, DVM, DACVD
The prevalence of Canine Pyoderma is increasing very quickly and the clinical condition can present in a variety of ways. It is a common secondary manifestation of a variety of clinical conditions like allergic skin diseases, endocrinopathies, autoimmune skin diseases, and keratinization disorders. An efficient and correct diagnosis is essential as is proper therapy in the face of ever-increasing development of Canine Methicillin-Resistant Staphylococcal Pyoderma.
Arthropods form a major group of disease vectors with mosquitoes, flies, sand flies, lice, fleas, ticks and mites transmitting a huge number of diseases.
Many such vectors are haematophagous, which feed on blood at some or all stages of their lives.
