Mycoplasmosis in dogs – a group of diseases that cause opportunistic microorganism of the class Mollicutes. To this class Three families belong to mycoplasma, acholeplasma and T-mycoplasmas. Therefore, microorganisms cause pathologies in different organs.

What diseases cause mycoplasmas
Species-specific mycoplasma parasitizes in dogs only for these animals – Mycoplasma cynos. Microorganisms cause:
- respiratory tract infections;
- kidney disease
- joint diseases
- diseases of the genitourinary system.
Mycoplasmas are normal bacterial microorganisms flora of the respiratory tract of animals. So, in the study, 27% healthy dogs were discovered mycoplasmas on the upper mucous membranes respiratory tract. But also in animals with various respiratory diseases were isolated M. bovigenitalium, M. Canis, M. CYNOS, M. edwardii, M. feliminutum, M. gateae, and M. spumans. Microorganisms cause disease in weakened animals, with reduced immunity.
In addition to these diseases, mycoplasmas are very dangerous for pregnant bitches, as infection causes miscarriages, birth nonviable or dead offspring, persistent infertility. Although most mycoplasmas are species-specific, infection may occur in direct contact with a sick animal. For example, a dog may become infected by contact with a patient. mycoplasmosis cat.
Symptoms and signs of mycoplasmosis in dogs
Mycoplasma infection cannot be determined without laboratory research. Pathology is manifested by symptoms of diseases, caused by damage to microorganisms of a particular organ. Symptoms correspond only to a secondary lesion. The owner of the animal needs pay attention to the following symptoms:
- redness of the sclera of the eyes, lacrimation, purulent discharge detachable;
- nasal discharge, runny nose;
- pain in the abdomen, upset stool, vomiting;
- inflammation, swelling of the joints of the limbs, lameness, pain with movement;
- lack of appetite, thirst;
- febrile events (chills, fever);
- skin pathologies (dermatitis, dermatoses, eczema), inflammation skin
- apathy, anemia.
Multisymptomatic pathology complicates the diagnosis and disguises the true cause of the disease.
The morphology of the pathogen causes difficulties with diagnostics. Mycoplasmas do not have a cell membrane and attach to the host cell, easily adapting to the shape of the cell. The microorganism receives nutrients directly from the cell substances and growth factors. Due to the fact that the cells of the microorganism and the host exchange proteins, the immune system can not recognize pathogen.
Often this interaction leads to the opposite effect – cells of the immune system begin to fight not only with microorganism, but also with its own cells – begins autoimmune pathological process. In order to install accurate diagnosis, use the study of swabs from the bronchi and trachea, samples from the nasal mucosa, smears from the eyes, reproductive system.
Using the method of polymerase chain reaction (PCR) is determined the presence of pathogen DNA in samples. However, due to the large species mycoplasma diversity may require several tests, to pinpoint all types of pathogens.
For confirmation, a blood culture may be required. Analysis used to be the main diagnostic tool. Through this analysis determines the sensitivity of microorganisms to various groups of antibiotics. Additionally can be assigned studies that help determine the condition of the affected organ infection:
These research methods are not specific and reveal secondary pathologies, and not the presence of a pathogen.
Therapy of mycoplasmosis in dogs
Treatment of a sick animal is long and includes antibacterial and symptomatic therapy. Mycoplasmas sensitive to certain groups of antibiotics, for example tetracycline series, which inhibit the synthesis processes in non-nuclear microorganisms. For treatment are prescribed:
- antibiotics (tetracyclines, chloramphenicol, doxycycline);
- antimicrobial agents;
- local antimicrobial agents.
During the entire treatment course, studies are carried out that show the effectiveness of the treatment and help to adjust it if necessary. Long-term use of strong antibiotics may damaging the dog’s liver, therefore, as maintenance therapy is prescribed hepatoprotectors. To normalize intestinal microflora, treatment supplemented with probiotics and prebiotics.
In the treatment of conjunctivitis caused by mycoplasmas, it is not necessary use local steroid preparations (ointment). Otherwise treatment can lead to a chronic process and the appearance of ulcers.
Tetracycline antibiotics are not prescribed for dogs younger six months. In pregnant bitches do not use tetracyclines and Chloramphenicol. Treatment is not prescribed before delivery. For delivery at sick bitches use cesarean section. Newborn puppies examined for the presence of mycoplasmas, since infection of the offspring occurs in utero.
In addition to the listed antibiotics may be prescribed alternative drugs – Erythromycin, Kanamycin, Spiramycin, Nitrofurans, Tiposin, etc.
Prevention of pathology in a dog
There is no specific vaccine for the prevention of mycoplasmosis exists. In order to suspect mycoplasmosis at an early stages, you need to regularly inspect the animal, and at first signs of pathology contact a veterinarian. With timely seeking help and adequate treatment prognosis of the disease positive.
