The retrovirus are recognized as pathogenic group of virus for domestic animals. The particularitities of these viruses are the necessity of the enzyme transcriptase reversa, for the conversion of the viral RNA in viral DNA (provirus) and the incorporation in the DNA of the cell, what it confers to the infection the lifetime character, due to all the infected cells present the provirus our DNA. Among the retroviruses in domestic felines, the leukaemia and immunossupressive virus represent the more important diseases. The main form of transmission of the virus of the FeLV is occur by close contact and the saliva presents high viral concentration. For the FIV, the main form of transmission is represented by wounds of bite. The retrovírus, replicate mainly in high metabolization cells. The infection for FeLV cause mieloproliferativas and degenerative illnesses, while the FIV are related imunossupressora illness. The treatment for these retroviroses is symptomatic associated to imunomodulatory drugs, none of these drugs are capable to eliminate the virus. For the prevention of these retrovirus are used vaccines. However only the vaccine against FeLV have showed efficiency. Thus , the more important measures in control of these diseases is prevent the contact between infected and health felines. The ain of present study was reviewed the more important aspects of retroviruses in domestic felines, with emphasis to virulence properties, epidemiology, fisiopathogeny, clinical manifestations, methods of diagnosis, therapy, and control measures

The rhodococcosis affects humans and animals. Equine are the most important species for rhodococcosis, which is considered the most debilitating disease in the creation of foals, leading to a mortality rates greater than 50% in this category. The disease is caused by Rhodococcus equi, a bacteria considered as a soil-born opportunistic microorganism, intracellular and ubiquitous. The disease in horses is manifested mainly in the form of pyogranulomatous pneumonia and less often in the form of enteric disorders and / or joint disorders. Transmission occurs mainly by ingestion of contaminated food and water, and inhalation in contaminated environment. The organism has mechanisms of evasion of the immune system, maintain viable in inside phagocytic cells, and induces piogranulomatous infections, leading to lesions of difficult treatment using conventional antimicrobials. Lipophilic drugs with good intracellular activity are required to successful treatment. The conventional treatment for foals is based on the combination of erythromycin and rifampin. However, there is a growing concern about the emergence of resistant strains, which makes increasingly studies on the development of alternative antimicrobials for therapy
