Ringworm in cats


The meaning and causes of ringworm


Ringworm is a fungal infection of the superficial layers of the skin, nails and hair. Ringworm infections can occur in all types of domesticated animals, and they can also occur in humans.

The name of ringworm comes from the classic appearance of the red circular ring that characterizes the limits of inflammation in people with the disease.The common name for ringworm is somewhat misleading, because the infection is not caused by the worm, and the affected areas are not always ring-shaped.

Organisms that cause ringworm infections belong to a group of fungi known as dermatophytes, so the correct medical name for this disease is dermatitis, some types of dermatophytes are specialized, which means they will not infect only one species, while other species can spread between Different kinds of animals or from animals to humans.

In cats, there is only one type of skin fungus, called "Microsporum Canis," which is also infectious for dogs and humans, and is responsible for all ringworm infections.

Ringworm infection in cats may be caused by other species such as "Trichomonas", which are also zoonotic and can infect humans.


Ringworm appearance


Ringworm lesions can be very mild or even undetectable, so it can be difficult to detect ringworm in cats.

Ringworm fungi feed on keratin found in the outer layers of skin, nails and hair.Cats may have thick, round patches of skin with hair loss.This occurs when the fungi infect the hair shafts, leading to the fragility of the affected hair.

The main sites of these lesions are the skin on the head, chest and front, along the edge of the back, so some cats may have thick round patches of skin with hair loss in cats.

 These lesions are usually not itchy, sometimes an infection in the claws, sometimes known as onychomycosis, can occur when the claws become rough and may eventually deform. In particular, long-haired breeds are often seen as incomplete hair loss.

Ringworm without any clinical signs or hair loss, these cats are called "asymptomatic vectors." These cats can infect other animals or even people, especially in multi-cat environments or shelters, without breeders knowing they are infected.


Ringworm transmission method


Ringworm is an infectious disease, and transmission to others may occur through direct contact with fungi, by handling contaminated objects, or by touching contaminated surfaces.

Fungal spores may remain dormant for several months on brushes, combs, food containers, furniture, carpet or other environmental surfaces.This period can be up to 18 months.

The most accurate way to diagnose ringworm in cats is by planting fungi in vitro.This is done by taking samples of skin and hair cuttings.A positive culture can sometimes be confirmed within two days, but in some other cases the fungus spores may be slow to grow , And the results can take up to 4 weeks, meaning that the suspected case cannot be considered negative for at least a month.
