What is Coccidia?

Coccidia are microscopic intracellular parasites that live and reproduce with in animal cells.

Most captive breed bearded dragons are host to coccidia. However, bearded dragons will usually show no symptoms as long as their immune system is strong enough to fight it. The damage done by coccidia could spread if a bearded dragon suffers several issues with its immune system.

Coccidia usually progresses to an infection (coccidiosis) when the immune system of the bearded dragon becomes too weak to fight off the damage inflicted.  Rapid reproduction of coccidia is a major cause of this infection in bearded dragons.

The infection is rampant among juvenile bearded dragons. However, older bearded dragons could suffer from this infection due to stress, overcrowding and poor nutrition. If not treated with urgency, coccidiosis can be deadly.

Mode of Transmission

As stated earlier, a bearded dragon can have coccidian and remain asymptomatic.

Here’s how bearded dragons become infected with coccidia:

When food comes in contact with contaminated surface and is ingested by the bearded dragon, it becomes sick with coccidiosis.

After ingesting contaminated food, the oocyst enters the gut. After which the oocyst wall is broken down, releasing sporocysts inside which are sporozoites. The sporozites proceed to attack the epithelial cell of the bearded dragon.

In the cell, the sporozites develop into merronts. Merolites (nucleuses of merronts) infect other cells, damaging them in the process. As this continues, they develop into either male or female gametes.

These gametes reproduce, forming zygotes. The zygotes proceed to build a wall around themselves, becoming oocyst. Once oocysts are created, the process starts all over again.

What are the Major Causes of Coccidia in Bearded Dragons?


A stressed bearded dragon has an increased chance of suffering from coccidiosis. Some dragons may not be comfortable in their captive environment, which increases the chances of stress. These dragons may resort to irregular movements around their tank and may unknowingly spread coccidia in their habitat.

Inadequate housing

A small tank isn’t advisable for any bearded dragon. It is important for owners to ensure proper housing for their bearded dragon at all times. Smaller spaces increases the chances of your bearded dragons spreading coccidia across their tank.

Poor dieting

Wrong diets could be a major driver of coccidian in bearded dragons. Your bearded dragons should receive numerous nutrients in their meals to ensure they maintain proper stomach health. Serving your bearded dragon the wrong food could lead to an increase in coccidian reproducing in its stomach.

Swift diet changes

Changing your bearded dragons’ diet on short notice could be another driver of coccidia. Ensure you maintain a strict diet template for your bearded dragon. However, if any food needs to be added or removed from your bearded dragon’s diet, consult your vet first.

Poor sanitation

Improper sanitation is another major reason why bearded dragons suffer from coccidia. Unsanitary surroundings littered with fecal matter are perfect for coccidian reproduction. Your bearded dragons stand a higher risk of infection if it lives in an unhealthy environment.


Packing two or three bearded dragons into a tank is never a great idea. If one of your reptiles currently suffers from advanced coccidia, the other bearded dragons will surely contract it. Each reptile should remain in its tank fitted with its own accessories for climbing, feeding, heating, etc.

Even if there are at least half-a-dozen possible causes of coccidia in bearded dragons, you can manage most of them. That’s why we’ll get to see what you can do to help your bearded dragons beat coccidia.

Signs and Symptoms Of Coccidiosis


The first sign of coccidiosis is usually diarrhea. In this case, the poop is not only watery; it smells bad and may have mucus in it (bloodless diarrhea). However, severe diarrhea could accompany coccidiosis in bearded dragons. Severe coccidioisis is usually accompanied by bloody stool along with other symptoms of bloodless diarrhea.


Constant dehydration is a major sign of coccidia in bearded dragons. Several dragons could grapple with being regularly dehydrated due to this infestation’s sudden spread. Rehydrating your bearded dragon helps, but you need to make an appointment with the vet immediately after you notice this symptom.

Weight loss

Bearded dragons could suddenly start to lose weight when there is a digestive issue or infection to handle. One of the main reasons for weight loss in bearded dragons is coccidia. Since some bearded dragons may not want to eat any food, the chances of emaciating become much higher.

Stunted growth

Inadequate consumption of food directly affects bearded dragons and limits their likelihood of growing. Juvenile bearded dragons are more likely to suffer from growth deficiencies since they’re in a transitional stage.

Lack of appetite, digestive problems, and other issues combine to make growth difficult for sick bearded dragons. Coccidia aggravate the likelihood of growth deficiencies, so you need to monitor this symptom closely.


The prolonged eating disorder linked to anorexia could become evident in bearded dragons plagued by coccidia. Reptiles could turn their noses up at every food you offer due to this ailment. Coccidia aggravates the likelihood of anorexia taking hold as it discourages digestion.

Reptiles suffering from anorexia usually have to deal with extreme digestive issues too.


Bearded dragons could suffer consistent bouts of vomiting when coccidiosis is advanced in their system. Indigestion may become aggravated in bearded dragons and cause these reptiles to vomit insects and other foods whole. Constant vomiting could result in a wide range of health challenges for your reptiles.

How to Treat Coccidiosis In Bearded Dragons?

To treat coccidiosis, the vet will assess the level of infection by placing a fecal sample under a microscope. The test, called a fecal flotation, helps the vet to get an accurate count of oocysts. Other techniques like the nested polymerase chain reaction can also aid in the diagnosis.

To treat coccidiosis, the vet will administer coccidiostat or any other remedial medication. Medications help stop reproduction among existing coccidia in the body of the host beardie.

Coccidiostat is mostly used to treat mild cases of coccidiosis. After stopping the reproduction of the coccidia, the immune system of the host is left to fight off and kill the already existing infestations.

Another medication used in treating coccidiosis is coccidiocidal. This stops reproduction, as well as kill existing coccidia in bearded dragons.
