Partial-gene sequencing of the MBLs was also performed to understand some<br>of the evolution history of those isolates.<br>Results: The P. aeruginosa was identified in 100 isolates. MBL-related MPCR results showed the presence of blaVIM, blaSPM,<br>blaGIM, blaNDM, blaAIM,blaSIM, and blaDIM genes in 16 (66.6%), and 14 (14.3%), 13 (54.1%), 1 (36.5%), 9 (37.5%), 8 (33.3%), 2<br>(8.3%), respectively, of the isolates. No detection of the blaIMP was observed. The phylogenic study demonstrated high matching<br>rates, 99%, with global strains from the NCBI-related database.<br>Conclusion: To the best of our awareness, the current work is the first in Iraq identifying metallo-β-lactamase genes in<br>Pseudomonasaeruginosa isolates.</p> Khawlah Jabbar Hussein Al-abedi, FiarsSrhan Abd Al-Mayahi Copyright (c) 2019 Al-Qadisiyah Journal Of Pure Science Mon, 16 Sep 2019 13:50:52 +0000 Genotype of Cryptosporidiumspp. isolated from human of Al-Qadisiyah province Iraq. <p><strong>Abstract:</strong></p> <p>The current&nbsp;&nbsp; study included examination of 100 stool sample from human was collected from AL-Qadisiyah province, from September 2018 until February 2019.the Microscopic examination&nbsp; result showed&nbsp; that oval or spherical shaped with dark pink color or red oocyst on blue ground and 22(22%) positive sample&nbsp; out 100 case .&nbsp; It was recorded that the highest rate 30% (3/10)&nbsp; was seen&nbsp; in September , but&nbsp; the lowest&nbsp; infection rate&nbsp; 13.3% (2/15) was seen in the month of December&nbsp; with no significant differences at level (p&lt;0.05.)&nbsp; regarding&nbsp; to age the high rate&nbsp; of infection 26.31%(10/38)was found&nbsp; in the&nbsp; group less than a year , but&nbsp; the lowest&nbsp; infection&nbsp; rate was observed in the&nbsp; group( &gt;12 years). There is no significant differences at p&lt;0.05.between man&nbsp; and women . In this study the N- PCR in molecular examination were&nbsp; used ,the positive sample was13 (59.09%) out of 22 stool&nbsp; sample.&nbsp; Sequencing of a fragment of the&nbsp; (18s&nbsp; rRNA) gene (834 bp) that separated&nbsp; from&nbsp; many&nbsp; different area&nbsp; in AL-Qadisiyah government&nbsp; recorded (75%)9/12 samplerelated to NCBI – Blast <em>Cryptosporidium hominis</em> isolates ,( 25%) 3/12 sampledisplay&nbsp;&nbsp; closed&nbsp; related to NCBI –Blast&nbsp; <em>Cryptosporidium&nbsp; parvum .</em>In Conclusion The current study concluded that phylogenetic tree and the homology sequences identity gives a clear differentiation of the types of <em>Cryptosporidium parasites</em> which can be isolated at high rates of human in AL- Diwaniyah province, which is likely to lead to an outbreak of Cryptosporidiosis in this province.</p> Al-Jawasim-A .D.G, -Khaled M.J.A.

The morphology<br>and structure of TiO2 nanowires were characterized by the scanning electron microscopy, X-ray diffraction, and energy<br>dispersive X-ray spectroscopy. The results emphasized the synthesis of it on the FTO at the optimum conditions such as degree<br>of temperature and reaction time.
