Very often I read the question “Can I infect my cat? ” or “Can I infect my cat? ” and I have the ever wondered in some diseases themselves. In this blog post I’d like to write something on zoonoses. “Zoonoses” – these are simply put diseases that can be transmitted between humans and cat (or dog, bird and rabbit etc. ) back and forth. So I rolled a few sources to get the issue on the track and I want you today to share with you the results of my research. What is even so a zoonosis? The “Federal Institute for Risk Assessment” defines the term “zoonosis” as follows: “Zoonoses are infectious diseases that can be caused by bacteria, parasites, fungi, prions or viruses transmitted mutually between animals and humans. ” Source: “What are zoonoses? ” Prions are the way the body’s own proteins that can cause diseases in certain circumstances.
As you can see, can a lot of “pathogens” for a transmission between humans and cats – and vice versa – to come into question. There are certain pathogens that are “host-specific” are – that is, they only affect a particular organism: only the dog, only the cat, only the man. But there are also exciting, which it is – floored said – no matter who they attack, they feel equally as comfortable, you are not so host specific. And there is also a third group of pathogens: namely those who preferred a main host ( “definitive host”), but also many possible intermediate hosts ( “hosts”) have. The intermediate hosts allow the pathogen growth to actual production. In him the exciter makes it so long comfortably until he is ready to attack the final host. In Endwirt then the pathogen can multiply by him more infective eggs, viruses are ultimately so widespread. All three groups are to answer the question “What is contagious? ” into consideration. How are transmitted zoonoses? Not only through the narrow coexistence of man and cat are those diseases transferable, and the enjoyment of certain foods may be suitable to. Particular foods such as meat, fish, vegetables, milk or eggs are to be mentioned here . Even a mosquito bite or a tick bite could transmit a zoonosis.
What “diseases” are from cat to man – and vice versa – transferable? bacteria “Arcobacter” are bacteria that mainly diarrhea – in humans and cat – trigger. You can in meat, stagnant water like puddles, but also occur in cat feces. “Bordetella bronchiseptica”: Even if a transfer of Bordetella bronchiseptica between human and cat is quite rare, it is theoretically possible . Bordetella are one of the possible types of bacteria, which are involved in the cat to an infection with the so-called “cat flu” complex. Both in humans and in the cat triggers an infection of a disease of the upper respiratory tract. Frequent symptom is cough. “Campylobacter spp. ” can be transmitted through infected meat or infected pets to humans. Symptoms include diarrhea and vomiting. Infected cats do not necessarily show symptoms, can still be contagious. “Chlamydia felis”: Also chlamydia involved in an infection with the cat flu complex.
You can also from the man on the cat – are transmitted – and vice versa. Symptoms of chlamydia infection is conjunctivitis . “Clostridia” are bacteria that cause diarrheal diseases mainly. Especially through infected food (meat) to be received from cat and man. It is possible – but not yet finally clarified – that these bacteria could be transmitted between humans and cats . “Coxiella burnetii”: this pathogen is transmitted primarily by infected ticks to humans and cats. he can Of an infected cat then in turn be transmitted to humans – for example, through contact with cat feces.  This bacterium is responsible for the disease, “Q-fever” is responsible: it is characterized by mild flu-like symptoms, but also partly chills, fever and severe headache from . “Enterobacter spp. ” are bacteria that occur in the intestines and can be transmitted, for example via the feces of infected cats / people. Infected individuals / cats may not necessarily show symptoms to be contagious. Infection with these bacteria may for example lead to blood poisoning, urinary tract infections, skin or eye inflammation . “Escherichia coli”: Every person and every animal has these bacteria in the gut.
Through contact with infected cats or their faeces, infection can be transmitted. It triggers urinary tract infections, bloodstream infections, and especially gastrointestinal disease – stomach ache, diarrhea, vomiting and nausea are the result [10,11]. “Listeria monocytogenes” are transmitted through contact with infected cats and their feces. Infection can flu-like symptoms, diarrhea and vomiting cause . Cats can be infected, for example, by infected food. “Salmonella” can (be notably risky considered poultry meat and raw eggs) transfer or through contact with the feces of infected cats to humans through contact with infected food. Usually show healthy cats no symptoms of infection, but the bacteria can spread to humans. Symptoms include diarrhea, for example, Bachweh and nausea [13,14]. “Staph” may be transmitted by bites and scratches of an infected cat or by contact with their droppings. Cat stuck for example on by eating infected meat. Symptoms of staph infection include nausea, vomiting, diarrhea, as well as purulent wound infections . parasites “Tapeworm / Hookworm / roundworm / Trichinella”: through the feces of infected cats can infect humans with worms.
Also an infection of the dog or contaminated food is possible. Possible signs of the worm infestation in humans include flu-like symptoms, abdominal pain, loss of appetite. Affected cats have often diarrhea, bloated bellies, dull coat or are cut off [16,17,18,20]. “Giardia” are single-celled intestinal parasites that can be transmitted through contact with the feces of infected cats to humans. They cause malodorous diarrhea, Bachweh, nausea and / or flatulence.  In Germany, reporting obligation exists in an infection by this parasite! “(Dross / mange) mites” solve severe itching, skin infections and skin infections from . They are transmitted from infected cats to humans and vice versa. “Cryptosporidiosis” is transmitted through contact with the feces of infected cats or by infected food. Infection triggers diarrhea, Bachweh, nausea and / or fever.  “Sarcosporidia”: Also sarcosporidia are transferable  through food and feces of infected cats. You solve not always symptoms, an infection may show but in humans by symptoms such as diarrhea and vomiting.
 “Toxoplasmosis” is transmitted through the feces of infected cats or by infected food (raw meat, unwashed fruits or vegetables) to humans. A primary infection is particularly problematic during pregnancy: a developmental disorder of the unborn babies is possible. An infection in adult humans and healthy cats runs symptoms usually. Symptoms of toxoplasmosis infection may include: flu-like symptoms, fever, swelling of lymph nodes [25,26]. mushrooms “Microsporum canis”: An infection with this highly contagious fungus is possible for all pets and humans! Symptoms – usually round – hair loss, redness of the skin and flaking. Not only the contact with infected animals, and the contact with infected objects and surfaces can lead to transmission. In Germany, reporting obligation exists in an infection by this fungus! “Ringworm” can be transmitted through contact with affected animals, contaminated objects and surfaces. Symptoms include redness, cancel the hair, hair loss and sometimes nodules of the skin [27,28]. viruses
“Cat Pox” are transmitted by the bite of infected cats transmissible to humans . Cats become infected by eating infected mice with this virus . In Germany, reporting obligation exists in an infection with this virus! Symptoms include skin lesions such as cold sores or pilling. In cats, these lesions occur mainly on the front paws and head. “Rabies” is transmitted by the bite of infected animals to humans. Symptoms are initially nausea, vomiting and headache. Later restlessness, seizures, aggression and anxiety will be added to water. Paralysis also can be observed in infected animals and humans. Infection with the rabies virus is fatal in almost all cases. . In Germany, reporting obligation exists in an infection with this virus! What are non-transferable?
Host specific and thus not be transmitted to humans are, for example, feline calicivirus and feline herpesvirus. Even the “feline AIDS virus” FIV is not transferable. Nor feline corona virus, which (in short “FIP”) can cause in mutated form, the feline infectious peritonitis. What precautions can I take into account? If you look at how zoonoses are transmitted, there is above all a “sticking point”: the cat feces. Cleaning the toilet should therefore be carried out as with the ulterior motive of Hygiene: Do not touch cat feces with bare hands, avoid contact with the skin or the mouth – yes, I know, but some people have to say anything – and thorough hand washing after toilet -Cleaning. After touching / handling an infected animal should wash your hands thoroughly also so that no body secretions reach sensitive areas. In certain zoonoses (especially fungal diseases) prevail very strict precautions: these should be observed only in case of infestation and are explained in need (hopefully) by the responsible veterinarian. What about a cold – can I infect my cat? This question may be a clear “Depends . . . ” answer):
