West Nile virus

Respiratory syncytial virus (RSV) is a very common virus that can cause mild cold-like symptoms in adults and older healthy children. This virus causes serious respiratory problems in infants, especially those infants which are born prematurely, who have diseases of the heart or lung, or those who are immunocompromised. The virus can live for a half an hour or more on hands and live for up to five hours on countertops or for several hours on used tissues. An RSV infection begins with the…

Pox virus is a double DNA virus that is best characterized by lesions that appear on the skin. The virus is identified using an electron microscope to find the brick shaped virions (King 2012). The use of Polymerase Chain Reaction (PCR) can identify which subfamily and genus the strand of pox virus is classified under. The family Poxviridae can be split into two subfamilies Chordopoxvirinae (vertebrate pox virus) and Entomopoxvirinae (insect pox virus) (Bracht et al 2005, King 2012). The…

, 2010). A balance that is mutually beneficial to the hosts response mechanism and virus replication is essential, meaning that the pathogen…

C-terminal region of the P3-6K1 complex carries a pathogenicity determinant in PPV (Saenz et al., 2000). Similarly, Suehiro et al. (2004) showed that TuMV contained an important determinant in the P3 C-terminal region, which conferred the ability of virus to infect different…

Feline Immunodeficiency VirusThe Feline Immunodeficiency Virus (FIV) was first isolated from cats in 1986 and wasdiscovered due to an outbreak of FIV infected cats housed together in several pens (Pederson112). FIV belongs to the family Retroviridae, the subfamily Orthoretrovirinae, and the genusLentivirus (Taniwaki et al. 551-552). Being that FIV is a lentivirus, this means that it’s a “slowvirus” with long incubation periods that could last for years (CFHC). FIV is present worldwideand “in the…

1.1 Caenorhabditis elegans (C. elegans) Caenorhabditis elegans is a free-living non-parasitic, non-infectious, non-pathogenic, transparent Nematode (roundworm). It has a full grown length of about 1mm, a life span of around 3 weeks and is found in temperate soil environments where it survives by feeding on microbes such as bacteria. [1] Consisting of about 1000 somatic cells as an adult, C. elegans is amenable to genetic crosses and produces a large number of progeny, at times even…

Evidence-Based Clinical Intervention Fifth disease, also known as erythema infectiosum, is a benign childhood condition that affects many children each year to its easy mode of transmission. As providers, understanding the etiology of the illness, presentation, differential diagnoses, treatment, and management, will be of high importance for all patients. This paper will discuss the medical problem, the pathophysiology of the infection, typical presenting signs and symptoms, three differential…

is usually caused by the virus HSV-1, or herpes simplex type 1, but can also be caused by HSV-2. In a previous study, it was found that 67.6% of Americans possessed antibodies for HSV-1, establishing HSV-1 as an exceptionally prevalent virus even in developed countries 9. The virus is spread through skin to skin contact between an individual exhibiting viral shedding, and an unaffected person, but can also be contracted through exposure to surfaces that contain the virus. Once HSV-1 is…

certain hosts. The impact of viruses on ocean biogeochemistry is often evoked purely through the act of host lysis, but very few studies have considered the chemical contributions of the viral particles themselves. Recent studies show that the marine virus particles contain significant amount of macronutrients (Carbon, Nitrogen, Phosphorous) and that the…

Parvovirus is a SS DNA virus, as stated in question it’s genome is either + or – strand. Their genome is linear, non segmented, and single- stranded DNA of about 5 KB. Most of the strand packaged into virions are – strand, but some parvoviruses package equal amounts of (+) and (-) strand. Parvovirus can’t become latent, since they are ssDNA and will be destroyed. All parvoviruses require receptor-mediated endocytosis for cell infection. Their host is Mammals including humans, parvovirus has all…
