Human respiratory syncytial virus

Respiratory Syncytial Virus (RSV) is a viral infection that affects young children and infants, but may also affect adults. RSV belongs to the family of paramyxoviruses and is classified in the genus pneumoviruses. There are at least ten polypeptides of RSV that exist. RSV is an ssRNA, enveloped virus ranging in size from 120-300nm, its envelope contains two proteins and two glycoproteins, according to virology-online. It has two subtypes A and B with, it is believed that subtype A exhibits more severe episodes. The incubation period of the disease is typically three to eight days. The virus attacks syncytium, defined by biology-online.org as “an epithelium or tissue from characterized cytoplasmic continuity, or large mass of cytoplasm not separated into individual cells and containing many nuclei” RSV outbreaks occur around the globe, however, in the United States RSV typically peaks during the…

in the winter months from October till mid to late March. The most commonly seen type of bronchiolitis is respiratory syncytial virus or RSV. It is reported that nearly all children will have had RSV by the age of two. Approximately 2-3% of child under the age of 12 months will be admitted to the hospital. Each year approximately 57,500 patients are admitted into the hospital and 2.1 million are treated in an outpatient setting (Smith, D. K., Seales, S., & Budzik, C., 2017). Children with…

Lower tract acute respiration infections (LT-ARI) has been estimated to cause 75% of all acute illnesses and are said to affect infants and young children worldwide. New respiratory viruses such as: human metapneumovirus (hMPV), new subtypes of human coronaviruses (hCoV), and bocavirus (hBoV), have been linked to LT-ARI. A common factor that affect LT-ARI studied in this experiment is age, although the prevalence is truly unknown. A study was conducted to aim an estimate prevalence of viral…

I executed fluorescent focus and TCID50 cell-based assays to quantify titers of respiratory syncytial virus (RSV) and influenza virus. I managed all RSV development/stability projects for titer testing. This experience sparked an interest in further exploring biomedical research as a career. As a result, I obtained a Master’s degree from the Johns Hopkins Bloomberg School of Public Health in the Molecular Microbiology and Immunology…

Breastfeeding effects on infant One of the most important health aspect that mothers always care about is their babies nutrition. However, mothers sometimes have incorrect beliefs they think that beliefs are healthy for the child. Some mother assumes that breastfeeding is the best way to feed the child , in contrast, others think formula feeding is better. Also, there are some mothers who do not know what is healthy and what is not. Therefore, mothers must understand the influences of…

however the role of this is unknown. Bordetella species, in general, grow best at 35° to 37° C. 1 Their growth is fastidious, and this degree of fastidiousness is inversely proportional to its rate of growth.1 Among all Bordetella species, Bordetella pertussis is the most fastidious and slowest growing; this slow growth is caused by the growth inhibition caused by fatty acids, metal ions, sulfides, and peroxides.1 Furthermore, this bacteria affect humans only and it has no known animal…

hand, others argue that animal testing is cruel and unnecessary because in most cases results aren 't always accurate. Others even maintain that animals and humans are completely different when it comes to ones anatomy and structure. My own view is that animal testing on chimpanzee’s should be banned because the testing is done repeatedly regardless of the fact that it won 't be effective…

the chances of breastfeeding. However, orientations from similar experts did not influence mother’s choices to breastfeed (Giugliani et al., 1994). It seems the greatest determinant factor is the more encouragement mothers receive increases their chances in engaging in breastfeeding their children. Breastfeeding has significance in consideration of infants’ survival, growth, and development. If mothers desire to breastfeed their children, several benefits accompany the process. Advantages like…

Envelope: In some cases a cell membrane of the host is utilized for encasement of the virus; this may be either the external cell membrane or the nuclear membrane. Infectious mononucleosis Infectious mononucleosis, or mono, refers to a group of symptoms usually caused by the Epstein-Barr virus (EBV). It typically occurs in teenagers, but you can get it at any age. The virus is spread through saliva, which is why some people call it “the kissing disease.” People with mono often have a high…
