The survey and identification source of white spot disease in shrimp Farm in Abadan area

In the summer of 2002 high mortality occurred in farm shrimp in Abadan area due to white spot disease. The main objective of this study was detection and identification the source of white spot syndrome virus. For this reason from 2004/11/4 until 2005/120/6 about 190 samples consisted of wild shrimp, crab, fish, and plankton collected and preserved in alcohol 90-75% for polymerase chain reaction (PCR).The samples transferred to the South Iranian Aquaculture Center in Ahwaz. The samples examined by commercial WSSV detection kit (Fast Target) and new kit design by Iranian Fisheries Research Organization (IFRO) and Biotechnology Research Center from Iran. The result from PCR showed the samples of Penaeus indicus brood stock and postlarvea, Parapenaeopsis stylifrus and Metapenaeus affinis was positive. The rest of samples did not show any sign of virus and they was negative by PCR. Because the disease outbreak occurred in 2002 and the samples collected in 2004, the situation of environmental in the area was changed and may be the virus disappears in the samples and died

Investigating prevalence of Helicobacter pylori and histological changes in patients with dyspepsia in Khorramabad City during 2013-2015

Dyspepsia which is a digestive syndrome with a prevalence of 50 in some areas can be an important factor in Helicobacter pylori infection syndrome. This study was aimed to evaluate relative frequency of Helicobacter pylori infection and histological changes in dyspeptic patients presented to the Endoscopic unit of Shahid Rahimi and Shohadaye Ashayer hospitals in Khorramabad city, Iran. In this cross-sectional study, the population included all patients with dyspepsia referred to Endoscopic Unit of Shahid Rahimi and Shohadaye Ashayer hospitals in Khorramabad during the period of 2013-2015. After performing endoscopy, H. pylori diagnosis was done by biopsy method. In this study, 5213 patients with dyspepsia (including 49.2 male and 50.8 female) with the age range of 12 to 90 years (mean 17.36 +/- 48.24 years) were studied. From this population, 57.3 percent were infected with Helicobacter pylori (50.8 of men and 49.2 women). Most positive cases were over 60 years old and the most histological changes were respectively chronic active gastritis (40.3). Similar to other studies, the prevalence of Helicobacter pylori infection is average in the population; however, these rates might be reduced through increased awareness and health care
