Soil oxalate degrading bacteria is an important source for removing of toxic oxalate compounds. Isolation, screening, characterization, identification and fingerprint of the soil oxalate degrading bacteria from Egyptian fertile soil was aimed in this work. Isolated bacteria were first characterized using API 20 NE system. Nine RAPD primers were used in genetic fingerprinting of the characterized bacteria using RAPD-PCR. The preliminary characterization and polyphasic taxonomy for mesophilic, aerobic oxalate-degrading bacteria isolated from Egyptian fertile soil including auxanography using API galleries confirmed that the isolate belonged to the genus Burkholderia cepacia, the percentage of identity was 99.8% for 5167777 profiles. Fingerprinting by RAPD-PCR showed a DNA fingerprint ranging from 0 to 9 bands, over a size range of 344 bp to 3,280 bp.

Introduction: The examination of three sputum samples per suspect has been severely criticized from a public health viewpoint and several recent trials have documented the relative inefficiency of the third smear and the necessity for confirmation of a positive smear has also been contested. Aim: This study, undertaken in Qena, Egypt, aimed to determine the usefulness of examining the second and third direct smear microscopy (DSM) specimen in the diagnosis of pulmonary TB. Patients and methods: A retrospective study using record review at TB outpatient clinic;Qena Chest Hospital, Egypt, was done from 2010-2013. Direct smear results were collected as one of the following combinations PNN, PPP, PPN, PNP, NNP, NPP, and NPN, NNN, where N is a negative and P a positive smear. The proportion of positive, first, second and third specimen were calculated. Cases were considered positive having at least one positive smear confirmed by another positive one in the absence of sputum culture. Results: Out of 9420 recorded suspects, 719 of them were positive, so smear positivity was 7.6%. The majority of them were diagnosed from the first sample (96.4%). For only 3.6% (26 of 719), the second smear was positive and a third specimen was required (NPP) to make a definitive diagnosis of TB. No recorded isolated positive or negative smears in the third sample (NNP or PPN). Conclusions: These data indicated that, in our locality with limited financial resources, the incremental yield of a second sputum direct smear examination was low, and the third one was negligible indicating that examination of two sputum samples is enough among pulmonary TB patients. A third sample is required only as confirmatory if the second sample was positive. Smear microscopy can be substantially simplified with favourable resource implications.

This work aims to characterize, synthesize and evaluate the biological activity of sodium barbitone and their metal chelates Ni(II), Pd(II) and Pt(II). The new synthesized metal chelates are investigated by elemental analysis, IR, mass spectra, thermal analysis and biological activity. Square planer structure of the prepared complexes obtained from the result of analysis. The antibacterial and antifungal of sodium barbitone ligand and its conforming metal chelates were screened against bacterial species Gram positive (Staphylococcus aureus), Gram negative bacteria (Escherichia coli) and fungi Aspergillus flavus and Candida albicans fungi. Ampicillin and amphotericin were used as references for antibacterial and antifungal studies. The activity data show that the platinum group metals chelates have activity data show that some of the platinum group metals (viz. Pt(II) and Pd(II)) chelates have a promising biological activity comparing to sodium barbitone parent free ligand against bacterial and fungal species.
