Rengpipat et al. successfully tagged the shrimp probiotiont Bacillus S11 with GFP and then monitored the presence of this probiotic within the digestive tract of the Black Tiger shrimp Penaeus monodon following dietary supplementation. Histological analysis of intestinal samples revealed that the GFP-tagged probiotic bacterium was viable and localised to the surface of the shrimp’s intestine. Influenza virus is a seasonal acute respiratory infection and is associated with significant morbidity and mortality in adults every winter. Similar to most other countries, the peak influenza season in China is associated with higher health care utilization. In China, weekly cases of influenza-like illness in acutecare settings throughout the country are reported to the Chinese National Influenza Center and are mainly attributed to influenza virus, predominantly influenza A virus and influenza B virus. In addition to the influenza viruses, other respiratory viruses can also cause ILI symptoms in adults, such as human respiratory syncytial virus, human parainfluenza viruses, including parainfluenza virus type 4, rhinovirus, adenovirus, human coronaviruses and human metapneumovirus. Thus, multiple respiratory viruses may circulate among adults and cause influenza symptoms. It is generally accepted that there are no symptoms specific to any viral infection. Some studies have attempted to identify signs or symptoms specifically associated with influenza virus or other viruses, but no definitive conclusions have been drawn. ILI data such as ILI rate and ILI count can to some extent reflect influenza activity, and ILI attack rates may be higher among adults during pandemics. In China, ILI data from larger hospitals can deliver valuable information that could be used for monitoring the onset of an epidemic. Peking University People’s Hospital, an affiliated and teaching hospital of Peking University, is a nonprofit health care LY2109761 institution that provides an exceptionally caring environment for patients and families, and extends care to patients of any nationality. PKUPH receives approximately 2,000,000 outpatient cases annually and patients from areas beyond Beijing account for forty percent of this figure. The Infectious Diseases Department of PKUPH is a national influenza surveillance sentinel unit. Some studies have focused on changes in ILI when pH1N1 is present. However, few studies have reported on whether there have been changes in viral etiology and distribution, as well as clinical and epidemiological characteristics of ILI, following a pH1N1 pandemic. The general population in Beijing, China has been exposed to the novel pandemic H1N1 influenza virus since mid May 2009. According to the Chinese CDC, as of May 2011, 136869 confirmed cases and 875 deaths from pandemic influenza H1N1 2009, have been reported nationwide in mainland China. In this study, approximately 29.4% of the samples were positive for at least one virus, which is consistent with the results of other studies, in which between 0.9-27% and 44% of reported samples were positive.
