This study included the collection of 374 samples (distributed according to the source of collection ) as clinical samples (urine, wounds, burns, feces) from Ibn – Al – Baladi childbirth Hospital, AL- Yarmouk Teaching Hospital and Imam Ali Hospital in Baghdad, from both genders of different ages. As well as environmental samples (Tigris river water in Baghdad and soil samples) were collected from Baghdad region at the same period. The bacterial isolation and identification were conducted on a total of 77 isolates of Escherichia coli (20.58%) after their testing on culture media , microscopic examination with the biochemical tests by using Api – 20 E and VITEK2. The results of sensitivity test against vancomycin showed that 73 isolates of Escherichia coli resistant (94.18%) and 4 isolates with intermediate resistance (5.19%) were performed on Muller-Hanton agar using disk diffusion method . Chromosomal and plasmid DNA were extracted for 31 isolates in a molecular techniques for precise identification. Molecular detection was achieved for all isolates ( of various pathogens ) by using a specific 16SrRNA gene . Owing to the resistance and sensitivity results obtained with the method diagnosis,29 clinical and 2 environmental samples were selected for detection and molecular study . This molecular study detected the vancomycin resistance genes of Enterobacteriaceae in Iraq for the first time . Both chromosomal and plasmid DNA were used in PCR technique to diagnose the Vancomycin resistance genes by using specific primers (VanA,VanB,VanC) . Results of the electrophoresis on agarose gel cleared that all isolated Escherichia coli possessed resistance gene on their plasmid DNA or chromosomal DNA or on both of them with variable ratios .

In this study, Staphylococcus aureus (S. aureus) isolates (32) were collected from different hospitals in Baghdad and were diagnosed by conventional methods. Antimicrobial susceptibility test was performed by disc diffusion method for ten antibiotics. Hemolytic production activity and Deoxy ribonuclease (DNase) production ability were detected. The biofilm production ability was detected by microtiter plate method. The diagnosis was confirmed using PCR to detect the thermostable nuclease gene (nuc). Then, PCR technique was used to detect the fibronectin binding protein A and fibronectin binding protein B genes (fnbA and fnbB respectively). The results showed a high prevalence (78%) of Methicillin-resistant Staphylococcus aureus (MRSA) isolates, Imipenem and vancomycin were the most affective antibacterial agents tested. All isolates produced DNase enzyme . On blood agar plate, 65.6% of isolates produced ?-hemolysis zones while (34.4%) of isolates did not produce any hemolytic zone. The results of biofilm production assay showed that 41% of isolates gave a weak positive results. All isolates (100%) that had been previously diagnosed as S. aureus by routinely used methods harbored the nuc gene. fnbA and fnbB were found in (100%) and (25%) of isolates respectively. Conclusion: Molecular detection of nuc gene by PCR has high specificity for identifying S. aureus with a low cost which requires less time as compared with biochemical methods. fnbA and fnbB genes are important virulence factors of S. aureus. fnbA gene is the highest prevalence of toxinogenic and can be used as a genetic marker for diagnosis of local S. aureus isolates while fnbB gene does not play an important role in infection of S. aureus.

Journal of University of Anbar for Pure Science , volume:11 issue:3

Contrasts in argument about obesity and osteoporosis still concerning number of researchers. Published literatures mentioned many reasons for why such contradictory results were obtained. In this study some of the factors that believed to affect osteoporosis will be considered and investigated. Age of participated women ranged between 42-79 years. Out of 110 participants, 75 (68.18%) were practicing osteoporosis whereas 35 (31.82%) were not. The study revealed that weight and age are not risk factors of fracture. Family history is not associated with osteoporosis. Vitamin D deficiency and incidence of fractures are found to be significantly associated at p-value less than 0.01. Percentage of vitamin D deficiency in women with fractures was 55.81% while those without fractures was 44.19%.

Hussein I.Z. Al-Sudani , Ahmad A. Ramadhan , Bato

Journal of University of Anbar for Pure Science , volume:11 issue:3

The water balance equation for any natural area or water body indicates the relative values of inflow, outflow and change in water storage for the area or water body. Analysis of watersheds and drainage patterns of the studied area plays a vital role in understanding the hydrogeological behavior and expressing the prevailing climate, geomorphology and structural antecedents of terrains. This research will study the climate characteristics and meteorological water balance to calculate runoff and groundwater recharge as water surplus. The research used the meteorological parameters recorded in Hit station during the period (1995-2010) to describe climate conditions as well as calculating water surplus using Thorntwaite formula. The climate of area classified as hot dry in summer and cold low rainfall in winter as a continental semi-dry to dry climate class. The calculated potential evapotranspiration was (1174.3) mm, while calculated actual evapotranspiration was (69.59) mm. The amount of water surplus was (31.71) mm, divided into (20.26) mm as runoff and (11.45) mm as groundwater recharge. The average annual of groundwater recharge in the area was (72,020,500) cubic meters. The estimated percent of the water surplus and deficit from the annual rainfall was (31.3%) and (68.69%) respectively.
