streptococcus agalactiae , s. dysgalactiae and s. uberis are gram-positive bacterial pathogens that affect cows in dairy herds. these are considered as the major causes of economic losses of dairy producers without a control program. to reveal the role of these agents in inducing subclinical mastitis in dairy cattle in ahvaz, 100 cmt-positive milk samples and 20 cmt-negative milk samples were c...
the development of the dominant lactobacilli population during traditional liqvan cheese production was investigated using two different molecular methods of: culture dependent rapd vs culture independent dgge. either one of the techniques showed a high degree of capability to identify and detect of this group of lactic acid bacteria. however, some differences were conspicuous during the detect...
The diagnosis of periprosthetic joint infection is sometimes straightforward with purulent discharge from the fistula tract communicating to the joint prosthesis. However it is often difficult to differentiate septic from aseptic loosening of prosthesis because of the high culture-negative rates in conventional microbiologic culture. This study used quantitative reverse transcription polymerase...
The success rate of embryo production critically depends on several factors. One of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (IVF) and in vitro embryo culture (IVC) (1, 2). Besides the technique selected for IVF / in vitro embryo production (IVEP), there is an important consideration called IVF/IVEP culture dishes disin...
One current challenge in microbial ecology is elucidating the functional roles of the large diversity of free-living and host-associated bacteria identified by culture-independent molecular methods. Importantly, the characterization of this immense bacterial diversity will likely require merging data from culture-independent approaches with work on bacterial isolates in culture. Amphibian skin ...
BACKGROUND Bacterial meningitis is more common in the neonatal period than any other time in life; however, it is still a challenge for the evidence based diagnosis. Strategy for identification of neonatal bacterial meningitis pathogens is presented by evaluating three different available methods to establish evidence-based diagnosis for neonatal bacterial meningitis. METHODS The cerebrospina...
