Background:Mycoplasma synoviae is an important avian pathogen which can cause both respiratory disease and synovial joint inflammation (synovitis) in poultry. Mycoplasmas spp. may cause the respiratory system infection in ostriches with symptoms such as inflammation of the nose, trachea and also damages of lungs. Objectives: The current study aimed to use the M. synoviae specific Polymerase Chain Reaction (PCR) and microbiological methods in order to isolate and identify M. synoviae from suspected ostriches in Kerman Province, Iran, and compare the two methods (microbiological and PCR) employed to confirm Mycoplasmal contamination of ostrich lungs. Materials and Methods: Fifty three samples of different parts of lung and trachea were immediately collected after slaughtering the ostriches in Kerman Province six months. Samples were cultured in the same conditions in pleuropneumonia-like organism (PPLO) broth and to isolate and identify M. synoviae, PCR and microbiological methods were conducted. The identified isolates were confirmed by specific amplification of 16S rRNA gene (163 and 207 base pair).Results: In the current study, 25 and 17 out of 53 ostrich samples were identified as Mycoplasma-positive in the PCR and microbiological methods, respectively; and 13 out of 25 the mentioned Mycoplasma-positive samples were also confirmed by PCR method.
Conclusions:The current study showed that PCR method is time consuming, effective, and efficient method to detect M. synoviae infection in ostriches. PCR method could be recommended as an alternative for culturing; M. synoviae was isolated from ostriches for first time in Kerman Province, Iran.
Background:Infection of urogenital system with Mycoplasma potentially affect reproductive system and increases infants mortalities. Therefore, detection of these organisms is an important issue that should be considered and appropriate diagnostic methods should be used to identify these microorganisms. In the female reproductive system, infection can affect different parts of the cervix, endometrium, and fallopian tube. The extent of this infection in different diseases and its pathogenesis might be related to anatomic site of involvement. Some infections can lead to infertility in both males and females. Genital infection with Mycoplasmas have devastating effects on reproductive organs and cause fertility disorders and mortality in infants. In recent years, many studies have been conducted to isolate these pathogens; however, the isolates have not been identified so far.Objectives:The aim of this study was to determine the molecular identity of Mycoplasma hominis isolated from infertile female and male reproductive system in the Infertility Center of Kerman.Materials and Methods:This descriptive study was performed purposefully on 100 infertile females and 100 infertile males who were referred to the Infertility Center of Kerman during a six-month period. The collected samples of semen and vaginal swabs were examined for the presence of M. hominis by PCR. The samples with positive results in PCR were selected for molecular identification. Alignment of samples sequence was performed using MEGA 5 software through Neighbor-joining method.Results:Among 100 samples from infertile males, the presence of genus Mycoplasma was confirmed in 45 cases of which 15 cases were infected with M. hominis. Among 100 samples from infertile female, the presence of genus Mycoplasma was confirmed in 43 cases of which 18 case were infected with M. hominis. The positive samples were sequenced and the phylogenetic tree was plotted.Conclusions:The results showed that 37.5% of infertile males and females were infected with M. hominis. Analysis of the nucleotide sequences of the study isolates indicates a particular variety among these isolates. In comparing the isolates in the study, a very little genotypic similarity was found among some of them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
