Overview
Pigeons : they ’re everywhere , specially if you live in or chaffer a with child city like New York City . pigeon are beautiful , gentle slight bird . They even have a part in war history due to their power to wing long space with message attached to their leg . But why are they cry “ flying rats ” ? Perhaps it ’s because pigeons can carry germs that can make favorite and people sick .
Pigeons — as well as some other wench — are bonk to hold a fungus that can cause an unwellness called cryptococcosis in cats , human being , and other species , including dogs . But before we fault pigeons for this disease , show more to better understand the many situation it can come from , what symptom to keep an eye on for , and how to process it .
What Is Cryptococcosis in Cats?
Fungal transmission is rare in cats , affecting only about 7 out of every 10,000 cats ( 1 ) . Cryptococcosis is the most commonfungal infection in cat , but it is not common by any means . Cryptococcosis means infection with the fungusCryptococcus — typically , Cryptococcus neoformansorCryptococcus gattii .
The fungus is first inhaled into the nose and lungs and can spread throughout the body through the bloodstream . Most commonly , it spreads from the pinched cavity to the cutis , eyes , and central uneasy system , such as the backbone and the brain . Cryptococcosis is particularly severe in cats if it infects the central nervous system and heart . medicine do not reach these areas well , and the symptom are severe .
Cryptococcusinfects indoor and outside Caterpillar alike — indoor - only quat can be infected ! All ages of cats can be bear on , but immature guy are more likely to get the disease . Certainbreeds of catshave higher rates of cryptococcosis , include Siamese , Himalayan , Birman , and Ragdoll strain .
Cryptococcosis in Cats:Causes
Cryptococcusis get worldwide . cat breathe in the fungus by interact with birds or their stool ( poop ) , or by exposure to many other outdoor elements , such as soil , Sir Herbert Beerbohm Tree , water , and air . Birds — especially pigeons — have the fungus in their stern , and pigeons can even hold it on their plume or different area of their body . Indoor cats are thought to be expose toCryptococcusfound in plant soil or mulch used on indoor plant . guy may also be infected by have a wound that allowsCryptococcusto enter the body .
Once cats inspire the fungus , it stick to the facing of the nasal cavity and/or the lungs . The protective capsule around the fungus grows , preclude the body from getting rid of it . The capsule forestall the dead body ’s resistant system cell from eating and destruct it ( a operation known as phagocytosis ) . The ejection seat also limits the body ’s reception , so many immune system cells meant to protect the body may not recognize it as big or may not send cadre to fight it . Cryptococcuscan then spread to other areas of the body through the blood stream .
Per the Centers for Disease Control and Prevention ( CDC),cryptococcosis is not contagious(2 ) . This intend that CT can not spread the contagion to one another , and cats do not propagate the disease to humans . In theory , it is possible , but this has never been proven or shown to occur .
CryptococcosisSymptomsin Cats
There are many potential signboard of cryptococcosis because the fungus can taint any part of the body and have a change of symptoms . The fungus is very small — too small for the eye to see . The most coarse cryptococcosis symptoms in cats admit :
The skin is affected in about half of cats with cryptococcosis . The most common areas affected are the face , capitulum , and paws . These peel symptom may include :
Approximately one - quarter of cats with cryptococcosis have symptom in the eyes and the central nervous system . These symptom may admit :
heart
Central uneasy organization ( i.e. , brain , spinal corduroy )
In rare case , hombre may develop urinary tractsymptoms , such as urinating outside the litter box or in pocket-size quantity multiple times per daylight ; hitch on legs with swelling around roast ; kidney disease causing vomiting and ecumenical symptoms of not feeling well ; and ulcerations in the mouth leading to pain and bad breather .
DiagnosingCat Cryptococcosis
Veterinarians will first execute a thorough physical interrogatory on the cat , looking for abnormalcy in a change of body systems . A classic finding is a with child bump on the bridge of a cat ’s nose , but that is not always present . Sometimes veterinary surgeon can name cryptococcosis under the microscope by finding the fungus in outpouring from the olfactory organ or skin using cytology . However , laboratory testing on blood , urine , discharge , and occasionally cerebral spinal fluid ( CSF ) is likely required .
There are many tests to look for cryptococcosis , and at times diagnosis is unmanageable . Multiple mental test are likely needed . universal ancestry work helps identify which organs are take with the infection . Discharge from the nose , fluid from skin lesions , urine , sample distribution of CSF , and samples of tissue paper can be cultured to uprise the fungus in the research laboratory . Samples of tissue paper ( i.e. , a biopsy ) can also be try by a diagnostician , who may find the fungus in the sample distribution . Blood can be sent to the lab to look for antibody in very high quantities , which would powerfully hold up the diagnosis of cryptococcosis . This blood test is not always accurate if the fungus is only found in one area of the body or in the central nervous system . Another rip test called polymerase chain chemical reaction ( PCR ) testing is available that looks for genetic material ( DNA ) of the fungus to name contagion .
Treatmentfor Cryptococcosis in Cats
Cryptococcosis require the use of fungicidal medication over farseeing periods of time , typically four month to a year . About one - third of cats may experience relapses ( 3 ) , which would ask retreating your cat with antifungals again in the future . Most cats take fungicidal medication at dwelling house until two months after symptom solve , or blood testing no longer showsCryptococcusis nowadays .

In theory , cats could shed some fungus in their secernment , but it does not get into the zephyr , which is the path that human being are infected ( after inhaling spore ) .
Is cryptococcosis in cats contagious to other cats?
No , cryptococcosis does not open from cat to cat . Cats become infected by inhaling ( or take a breather in ) fungal spore from dirt , trees , water , air , or through interactions with birds or their feces .
