Mycoplasmas are an important and economically significant cause of mastitis in dairy cows in various parts of the world. The organisms are highly contagious, with the main reservoir of infection originating from cows with subclinical mastitis. In 1998 the 1st cases of bovine mastitis due to Mycoplasma bovis were diagnosed in Ardabil State, Iran. An investigation was carried out with the aim of ...

Mycoplasmas are "minimal" bacteria able to infect humans, wildlife, and a large number of economically important livestock species. Mycoplasma infections include a spectrum of clinical manifestations ranging from simple fever to fulminant inflammatory diseases with high mortality rates. These infections are mostly chronic, suggesting that mycoplasmas have developed means to evade the host immun...

Mycoplasmas are important  avian  pathogens,  which  can  cause  both  respiratory  disease  and  synovitis  in  poultry  that  result  in  considerable  economic  losses  to  the  poultry  industry  all  over  the  world.  The  aim  of  this  study  was  to  determine  the  prevalence  of  Mycoplasma  gallisepticum  and  Mycoplasma  synoviae  infections  among  commercial  poultry  flocks  in ...

In the present paper we demonstrate that the cytostatic and antiviral activity of pyrimidine nucleoside analogues is markedly decreased by a Mycoplasma hyorhinis infection and show that the phosphorolytic activity of the mycoplasmas is responsible for this. Since mycoplasmas are (i) an important cause of secondary infections in immunocompromised (e.g. HIV infected) patients and (ii) known to pr...

Although Mycoplasma haemofelis and "Candidatus Mycoplasma haemominutum" infections have been reported in wild cats from United States, their presence among native and captive wild cats in Brazil is still unknown. A 12 year old healthy male lion (Panthera leo) from the Zoological Garden of Curitiba, Brazil was anesthetized for transportation and dental evaluation. A blood sample was obtained for...

A retrospective study of Mycoplasma otitis in California calves submitted for necropsy between 1993 and 2002 was conducted to characterize the demographic features of the disease and the pathologic findings associated with infection. Sixty-one confirmed cases of Mycoplasma otitis were identified among 20,525 necropsied cattle. All affected animals were calves, ranging in age from 2 weeks to 4 m...

one of the main problems in cell culture is mycoplasma infection. it can extensively affect cell physiology and metabolism. as the applications of cell culture increase in research, industrial production and cell therapy, more concerns about mycoplasma contamination and detection will arise. this review will provide valuable information about: 1. the ways in which cells are contaminated and the...

Background Reactive arthritis, Reiter’s syndrome is one of the seronegative arthropathies, that can be associated with intestinal infections (Shigella, Salmonella, Yersinia, Campylobacter jejuni, Clostridium difficile), sexual infections (Chlamydia trachomatis, Ureaplasma urealyticum) and lung infections (Chlamydia pneumoniae, Mycoplasma pneumoniae). Reiter’s syndrome is an arthritis that occur...

Mycoplasmas are highly fastidious bacteria, difficult to culture and slow growing. Many species of mycoplasmas are important pathogens that cause respiratory infection in laboratory animals and that are known to affect experimental results obtained with contaminated animals. The aim of the present study was to develop a sensitive and specific assay for the detection of mycoplasma species. To th...

Genital Ureaplasma urealyticum infection is considered to be a sexually transmitted infection. The bacterium has been found to be involved in PID, chorioamnionitis, urethritis, respiratory distress syndrome and pneumonia in newborn, abortion and infertility. U. urealyticum infections not only jeopardize fertility but also pose a risk for infertility treatment and resulting pregnancies. The purp...
