Tritrichomonas foetus is a protozoan organism that can cause predominantly large intestinal diarrhoea in cats. It is specific to cats, distinct from other Tritrichomonas species and not considered to be zoonotic. Infection is most common in young cats from multicat households, particularly pedigree breeding catteries.
Feline cryptococcosis is caused by basidiomycetous yeasts of the genus Cryptococcus belonging to the C. neoformans-C.
Aspergillosis is a sporadic mycosis that occurs worldwide in mammals and birds. Similar to the disease in humans, aspergillosis in cats can be classified by anatomic location, invasiveness, duration of infection, host immune status, pathology, and pathogenesis.
In contrast to single-celled yeasts, dermatophytes (literally: “skin plants”) are complex fungi growing as hyphae and forming a mycelium. Almost 40 species belonging to the genera Microsporum, Trichophyton and Epidermophyton are considered as dermatophytes.
The pathogenic role of many Bartonella spp. as pathogens of humans and domestic animals is still unknown. Bartonella henselae is the causative agent of cat scratch disease (CSD) in humans, a self-limiting regional lymphadenopathy and cats are its main reservoir host.
Capnocytophaga canimorsus and C. cynodegmi are part of the normal bacterial flora in the oral cavity of dogs and cats; C. canimorsus is more pathogenic and causes more severe infections in humans.
The natural hosts of ADV are domestic and wild suids. The clinical signs in these animals include respiratory, reproductive and neurological signs, depending on the age of the animal. Like other herpesviruses, ADV produces a latent infection in the host.
Papillomaviruses cause cutaneous lesions in man and several animal species, including cats (Munday, 2010). In each host different papillomavirus types exist, which is also true for cats (Munday, 2008).
Pasteurella multocida, a gram-negative, facultative anaerobic, non-spore-forming pleomorphic coccobacillus, is a commensal bacterium and part of the natural flora in the nasopharynx and upper respiratory tract of the cat (Freshwater, 2008;
Coxiella burnetii is a Gram-negative, obligate intracellular, small, pleomorphic bacterium belonging to the order Legionellales. This organism has a complicated life cycle with different morphological stadia. It may occur as a small-cell variant and a large-cell variant.
Leptospires are mobile, thin, filamentous bacteria of a size of 6.0-25.0 mm length and 0.1-0.2 mm width, that appear as fine spirals often with hook-shaped ends (Fig. 1) (Bharti et al., 2003; Adler and de la Pena Moctezuma, 2010).
The plague is currently endemic in many parts of the world and foci of plague occur in Asia, Africa and the Americas in semiarid areas where flea vectors are active all year round and rodent reservoirs are abundant (Valles et al., 2020).
Currently most of human cases occur in
This bacterial species was discovered in ground squirrels in Tulare County, California, in 1911. Tularaemia is a potentially fatal zoonosis mostly found in the Northern hemisphere.
Mycobacteria are intracellular, acid-fast, slow-growing bacilliform Gram-positive aerobic bacteria, highly resistant to environmental conditions (Greene and Gunn-Moore, 2006; Gunn-Moore, 2010). Mycobacterial taxonomy is complex, and many species can infect cats and cause different clinical presentations.
Feline herpesvirus (FHV), the agent of feline viral rhinotracheitis, is distributed worldwide. The virus belongs to the order Herpesvirales, family Herpesviridae, subfamily Alphaherpesvirinae, genus Varicellovirus.
Feline panleukopenia virus (FPV) and the closely related canine parvovirus 2 (CPV-2) can infect and cause severe disease in cats.
FPV is shed in high titers in the faeces and the very stable virions stay infectious in the environment for months.
FPV is very tolerant against many
Bordetella bronchiseptica (Bb) is a primary respiratory pathogen of cats, particularly in high population density conditions such as rescue shelters and multicat households.
Bordetella (B.) pertussis, B. parapertussis and Bb are closely-related Gram-negative coccobacilli that colonise the respiratory tracts of mammals. B.
Chlamydia felis is a Gram-negative bacterium that is an obligate intracellular parasite of cats. Chlamydia felis does not survive outside of the host so close contact between cats is required for transmission, usually via ocular discharges. Chlamydiosis typically affects young cats under 9 months of age.
Influenza is a highly contagious, acute infection, usually of the upper respiratory tract, and has been detected worldwide in many vertebrate hosts (Krammer et al., 2018). Feline respiratory diseases caused by influenza viruses appear to be rather rare and usually self-limiting;
Rabies is one of the oldest and most feared diseases of humans and animals – it was recognized in Egypt before 2300 BC and in ancient Greece, where it was well described by Aristotle.
The European Advisory Board for Cat Diseases aims to communicate scientific developments in feline infectious diseases, and therewith, to define a code of practice across Europe.
