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…

Respiratory Syncytial Virus RSV Educating parents about RSV can help inform them of what Respiratory Syncytial Virus is, how it affects children, what age group it is most commonly found in, how it can be prevented, and what treatments are out there for RSV. RSV could become deadly if the right preventative measures are not taken. Another risk factor could be mistaking the symptoms, of RSV with the common cold, or if your child is at a higher risk for RSV and you don't know. Being informed…

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…

Only humans can carry the highly contagious B. pertussis which is a gram negative microbe. The infection is spread by the cough of the infected to the respiratory tract of uninfected. Droplets of the cough attach and damage the individual’s ciliated respiratory epithelium. The bacteria have surface proteins that attach to the cilia, called pertactin and filamentous hemagglutinnin. Once these proteins attach to the cilia it is difficult to remove the bacteria and the proteins also produce…

For perspective, a human hair is 2,000 times that width. The particle is made from a tiny crystal of gold. A forest of even tinier threads cover its surface. Those threads are made from carbon-based compounds. Explainer: What is a virus? Stellacci’s group tested these tiny particles against a broad range of viruses. And they now report success. The nanoparticles destroyed common germs like the herpes virus and human papilloma virus. The first triggers a range of symptoms, including cold sores…

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…

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…

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…
