Molecular detection of infection (Q fever) in livestock in Makkah Province, Saudi Arabia.

The study aims to investigate the prevalence of Q fever in livestock and ticks in Makkah Province, Saudi Arabia, by molecular methods. Using DNA obtained from (40) blood samples, (60) vaginal swabs and ticks (120) samples. Real-time PCR was used to detect the insertion sequence of in aborted animals.

Endophytic bacteria isolated from Solanum nigrum L., alleviate cadmium (Cd) stress response by their antioxidant potentials, including SOD synthesis by sodA gene.

Cadmium (Cd) is a toxic heavy metal and an abiotic stressor to plants; however, inoculation of endophytic bacteria can raise resistance in plants against Cd, as well as improve plant growth. In the present study, two endophytic bacterial strains were isolated from Solanum nigrum, identified as Serratia sp. IU01 and Enterobacter sp.

Assessment of the bacterial contamination of hand air dryer in washrooms.

The present study was carried out, using standard techniques, to identify and count the bacterial contamination of hand air dryers, used in washrooms. Bacteria were isolated from the air flow, outlet nozzle of warm air dryers in fifteen air dryers used in these washrooms. Bacteria were found to be relatively numerous in the air flows.

Mycelium of fungi isolated from mouldy foods inhibits Staphylococcus aureus including MRSA - A rationale for the re-introduction of mycotherapy?

Fungal mycelium capable of producing antibacterial agents was isolated from samples of apple, beetroot, lemon and orange; the mycelium of all isolates produced penicillin, while the apple and beetroot samples also produced the antibacterial mycotoxin patulin. The known penicillin-producing fungi were shown to produce penicillin, but not patulin. The mycelial discs of all of fruit and vegetable isolates, as well as the two known penicillin producing fungi, inhibited Staphylococcus aureus, and mycelium of all isolates inhibited MRSA, in contrast, only one of the two known penicillin-producers did so.
