Mycoplasmosis in dogs is a group of diseases that cause a conditionally pathogenic microorganism of the Mollicutes class. Three families belong to this class - actually mycoplasma, acholeplasm and T-mycoplasma. Therefore, microorganisms cause pathologies in different organs.

What diseases cause mycoplasma
Mycoplasma, which is species-specific only for these animals, Mycoplasma cynos, parasitizes the dogs. Microorganisms cause:
- respiratory tract infections;
- conjunctivitis ;
- mastitis :
- kidney disease;
- joint diseases;
- anemia ;
- diseases of the genitourinary system.
Mycoplasmas are microorganisms of the normal bacterial flora of the respiratory tract of animals. Thus, in the study, 27% of healthy dogs had mycoplasma on the mucous membranes of the upper respiratory tract. But also M. bovigenitalium, M. Canis, M. CYNOS, M. edwardii, M. feliminutum, M. gateae and M. spumans were isolated in animals with various respiratory diseases. Microorganisms cause disease in weakened animals, with reduced immunity.
In addition to the listed diseases, mycoplasmas are very dangerous for pregnant females, since infection causes miscarriages, the birth of non-viable or dead offspring, persistent infertility. Despite the fact that most mycoplasmas are species-specific, infection can occur by direct contact with a sick animal. For example, a dog can become infected by contact with a sick mycoplasmosis cat.

Symptoms and signs of mycoplasmosis in dogs
Infection with mycoplasma can not be determined without laboratory tests. Pathology is manifested by the symptoms of diseases caused by the defeat of a particular organ by microorganisms. Symptoms correspond only to secondary lesions. The owner of the animal needs to pay attention to the following signs:
- redness of eye sclera, lacrimation , purulent discharge;
- separated from the nose, runny nose;
- pain in the abdomen, stool disorder, vomiting ;
- inflammation, swelling of the joints of the limbs, lameness, pain during movement;
- lack of appetite, thirst;
- feverish phenomena (chills, fever);
- skin pathologies ( dermatitis , dermatosis, eczema ), skin inflammation;
- apathy, anemia.
The multisymptomatic pathology complicates the diagnosis and masks the true cause of the disease.
Methods of diagnosing the disease
Features of morphology of the pathogen cause difficulties with diagnosis. Mycoplasmas do not have a cell membrane and attach to the host cell, easily adapting to the shape of the cell. Directly from the cell, the microorganism receives nutrients and growth factors. Because the cells of the microorganism and the host are exchanging proteins, the immune system can not recognize the pathogen.
Often this interaction leads to the opposite effect - the cells of the immune system begin to fight not only with the microorganism, but also with their own cells - an autoimmune pathological process begins. In order to establish an accurate diagnosis, use the study of flushing from the bronchi and trachea, samples from the nasal mucosa, smears from the eyes, the reproductive system.
Using the polymerase chain reaction (PCR) method, the presence of DNA of the pathogen in the samples is determined. However, due to the large species diversity of mycoplasmas, several tests may be required to pinpoint all types of pathogens.
For confirmation, you may need to digest blood. Analysis was previously the main diagnostic tool. With the help of this analysis, the sensitivity of microorganisms to different groups of antibiotics is determined. Additionally, studies can be assigned that help to clarify the state of the affected organs:
- Ultrasound .
These methods of investigation are not specific and reveal secondary pathologies, and not the presence of an agent.

Therapy of mycoplasmosis in dogs
Treatment of a sick animal is long and includes antibacterial and symptomatic therapy. Mycoplasmas are sensitive to certain groups of antibiotics, for example the tetracycline series, which inhibit the synthesis processes of non-nuclear microorganisms. For treatment are appointed:
- antibiotics (tetracyclines, Chloramphenicol, Doxycycline);
- antimicrobial agents;
- antimicrobials of local action.
Throughout the treatment course, studies are conducted that show the effectiveness of the treatment and help to correct it if necessary. Prolonged intake of strong antibiotics can have a detrimental effect on the liver of the dog, so hepatoprotectors are prescribed as maintenance therapy. To normalize the intestinal microflora, the treatment is supplemented with probiotics and prebiotics.
When treating conjunctivitis caused by mycoplasmas, do not use steroid preparations of local action (ointment). Otherwise, treatment can lead to a chronic process and the appearance of ulcers.
Antibiotics of the tetracycline group are not prescribed to dogs younger than six months. In pregnant females do not use tetracyclines and Chloramphenicol. Treatment is not prescribed until delivery. Caesarean section is used for delivery in patients with bitches. Newborn puppies are examined for mycoplasma, as infection of the offspring occurs in utero.
In addition to the listed antibiotics, alternative drugs may be prescribed - Erythromycin, Kanamycin, Spiramycin, Nitrofurans, Tipozin, and others.
Prevention of pathology in dogs
Specific vaccine for the prevention of mycoplasmosis does not exist. In order to suspect mycoplasmosis at an early stage, you need to regularly examine the animal, and at the first signs of pathology, go to the vet hospital. With timely access for help and adequate treatment, the prognosis of the disease is positive.
