| ABSTRACT In order to study and characterize the lesions in the reproductive tract of Nellore heifers naturally infected with Ureaplasma diversum and presenting granular vulvovaginitis syndrome (GVS), fragments of uterine tube, uterus, cervix, vagina and vulva of 20 animals were evaluated. The macroscopic lesions of the vulvovaginal mucosa were classified in scores of “1” mild, until “4”, severe inflammation and pustular or necrotic lesions. The histopathological evaluation was performed using scores of “1” to “4”, according to the inflammatory alterations. The fragments with severe microscopic lesions (3 and 4) were from the uterine tubes and uterus, which showed leukocytes infiltration and destruction and/or necrosis of epithelium. Alterations in the... |

| Foram utilizadas 112 amostras de muco vulvovaginal, coletados de vacas com distúrbios reprodutivos, para pesquisa de Mycoplasma e Ureaplasma. Para isolamentos, foram usados meios específicos para micoplasmas (SP-4) e para ureaplasmas. PCR genérica, PCR específica para Mycoplasma bovis e nested-PCR em tubo único para Ureaplasma diversum foram realizados com os DNAs extraídos das amostras. Mycoplasma spp. e U. diversum foram detectados em 12,5 e 25,0%, respectivamente. A PCR genérica resultou em reações positivas em 63,4% das amostras transportadas em SP-4 e em 69,6% das transportadas em meio de ureaplasma. M. bovis foi detectado, na PCR específica, em 9,8% das amostras e U. diversum, na nested-PCR, em 37,5%. Houve maior sensibilidade na metodologia da PCR... |

| BACKGROUND: Bacterial pathogens have many strategies for infecting and persisting in host cells. Adhesion, invasion and intracellular life are important features in the biology of mollicutes. The intracellular location ofUreaplasma diversum may trigger disturbances in the host cell. This includes activation or inhibition of pro and anti-apoptotic factors, which facilitate the development of host damage. The aim of the present study was to associate U. diversum infection in HEp-2 cells and apoptosis induction. Cells were infected for 72hs with four U. diversum clinical isolates and an ATCC strain. The U. diversuminvasion was analyzed by Confocal Laser Scanning Microscopy and gentamicin invasion assay. The apoptosis was evaluated using pro-apoptotic and... |
