“…in the vaginal mucus was low in comparison to the frequencies reported in other Brazilian states (Cardoso et al 1997, Cardoso et al 2000, Cardoso & Vasconcelos 2004, Buzinhani et al 2007, Santos et al 2013). However, it was possible to prove the viability of these microorganisms through bacterial isolation, thus highlighting the possibility of these agents causing reproductive diseases in these cattle during opportunistic outbreaks.…”

The aim of the present study was to report the occurrence of members of the Mollicutesclass in the reproductive system of dairy cattle in Brazil. Five farms containing dairy cattle were visited in January of 2012. In total, 100 cows of different ages, breeds and stages of lactation were examined in the present study. The cows were part of intensive or semi-intensive management systems and were submitted to mechanical milking or hand milking. The samples were collected after washing the vulvar region with water and soap, and then drying it with paper towels and disinfecting the area with alcohol (70°GL). Vaginal mucous was collected using a sterile alginate cotton swab, which was rubbed on the vagina, as well as the lateral and internal walls. Vulvovaginal mucous samples were cultured in both liquid and solid modified Hayflick´s medium, for mycoplasmas, and UB medium, for ureaplasmas. The PCR assays for Mollicutesand Ureaplasmaspp. were performed according to the standard protocols described in the current literature. During isolation, the frequency of Mycoplasmaspp. was of 13.0% (13/100) and for Ureaplasmaspp. was of 6.0% (6/100). In the PCR assays the frequency of Mollicuteswas of 26.0% (26/100) and for Ureaplasmaspp. was of 13.0% (13/100) in the dairy cattle studied. This is the first report of these agents in reproductive system of bovine of the Pernambuco state. Further studies are necessary to determine the pathogenic potential and species of these field isolates.

“…Вероятность заражения микоплазмами КРС, выращиваемого по полуинтенсивной технологии, в 4,6 раза выше, чем животных с выгульным способом содержания [16]. Связано это с тем, что при полуинтенсивной системе содержания КРС возрастает риск передачи патогена при прямом контакте животных [17].…”

Mycoplasmosis control remains urgent in view of wide spread of bovine mycoplasmoses in the countries with intensive animal farming and trade relations between the Russian Federation and foreign partners including import of pedigree livestock and stud bull semen. Results of testing 1,186 biomaterial samples (blood, sera, nasal swabs, milk, preputial swabs, vaginal swabs, aborted and stillborn fetuses) collected from animals that demonstrated clinical signs of respiratory and reproductive disorders in 34 different regions of the Russian Federation for 2015–2018 are presented in the paper. The samples were tested with real-time polymerase chain reaction (rtPCR) for genomes of the following mycoplasmosis agents: Mycoplasma bovis, Mycoplasma bovigenitalium, Mycoplasma dispar. As a result, M. bovis genome was detected in 10.1% of the samples, M. bovigenitalium genome was detected in 8.6% of the samples and М. dispar genome was detected in 37.15% of the samples. Also, 927 semen samples submitted from Russian and foreign breeding farms were tested with PCR. Test results showed presence of M. bovis and M. bovigenitalium genomes in semen samples collected from native bull population. Presented data support Russian scientists’ conclusions on wide mycoplasmoses occurrence in cattle in the Russian Federation territory and risk of the disease agent introduction through semen import. All of these highlight the need for control of semen products as a source for mycoplasmosis spread as well as insufficiency of single testing of semen for granting the disease-free status to the breeding farm for genetic material marketing.

Ureaplasma diversum has been associated with various reproductive problems in cattle that include granular vulvovaginitis, weak calves, and abortion. This study was conducted in a beef herd situated in the Middle-West region of Brazil, and the objectives were to verify the presence of U. diversum and to elucidate its possible relationships with independent variables in this bovine herd population. A total of 134 vaginal mucous swabs were taken for polymerase chain reaction (PCR). Of these, 51 (38 %) were PCR positive for U. diversum. Of the 58 heifers with vulvovaginal lesions characterized by hyperemia, granulated lesions, and edema distributed throughout the vulvar mucosa, 37 (64 %) were U. diversum positive; of the 76 heifers without reproductive lesions, 14 (18 %) were U. diversum positive. All tested samples were negative for bovine herpesvirus 1 (BoHV-1). Multivariate logistic regression revealed that the following two variables were significantly associated with the presence of U. diversum: the presence of vulvar lesions (p = 0.001) and the presence of a progesterone (P4) device (p = 0.001). These findings indicate that U. diversum should be considered a pathogen that is associated with pustular vulvovaginitis in heifers from the Mato Grosso state and that additional studies of the risk factors associated with intravaginal P4 device transmission should be performed.
