Potential vaccines exist for both the zaire and sudan ebola virus strains recent events in west africa increased the urgency for an ebola vaccine and fast-track clinical trials were undertaken [ 17 - 19 . It also causes ebola virus disease in human and non-human primates belongs to genus ebolavirus which has other four species including zaire • subtype sudan. News west africa the challenges of finding a vaccine for ebola zaire ebola strain and does it mean they cannot be used for the reston and sudan strains. The entire genomic rna of the gulu (uganda 2000) strain of ebola virus was sequenced and compared to the genomes of other filoviruses this data represents the first comprehensive genetic analysis for a representative isolate of the sudan species of ebola virus. Within 48 hours of receiving the specimens, sequence analysis on the pcr dna (528 bp) amplified from the glycoprotein gene derived from four different patients showed that the ebola virus was a zaire subtype that differed from the original 1976 strain in four bases (1%.

The filovirus family consists of four simlar viruses: marburg, ebola zaire, ebola sudan, and ebola reston each strain consists of seven proteins, four of which are unknown gangrene. Ebola classification and taxonomy ebola sudan, ebola zaire, ebola cote d'ivoire, and ebola reston are the four known strains (subtypes) of ebola. However, the case fatality rate was below 50% in this outbreak, compared to 80-90% found in earlier outbreaks caused by other ebola virus strains, like zaire ebolavirus 1 1 macneil a, farnon ec, morgan ow, et al filovirus outbreak detection and surveillance: lessons from bundibugyo [pdf - 203kb].

There are four subtypes of the ebola virus that have occurred in humans: ebola sudan, ebola zaire, ebola ivory coast, and ebola bundibogyo there was also a case of ebola that occurred in a non-human in reston, virginia. There are five species: zaire ebolavirus , sudan ebolavirus , taï forest ebolavirus , bundibugyo ebolavirus , and reston ebolavirus 1 fig 1 infographic on ebola virus disease zaire ebolavirus is responsible for the current outbreak in west africa, the largest outbreak since the virus was discovered in 1976 (fig 2⇓. The who confirmed that the current strain of the virus in the boende district is the zaire ebola species this strain is common in the country and similar to the 1995 kikwit outbreak in the drc the virology results and epidemiological findings indicated no connection to the current epidemic in west africa.

For example, analysis of 802 nucleotides of the vp30 gene placed ebola sudan with ebola ivory coast + ebola bundibugyo, rather than with ebola reston, and analyses of the glycoprotein and l genes showed some conflict in the topology within the ebola zaire clade in neither case were the conflicting topologies well supported. Both deterministic and stochastic seir (susceptible-exposed-infectious-recovered) dynamic models have been used to study the 1995 and 2000 ebola outbreaks in dr congo and uganda, which were caused by the zaire and sudan virus strains, correspondingly 7, 8 legrand et al 9, in particular, analyzed data from these two epidemics with a sixth. Amanda b keener, studying ebola survivors, a scientist jumps at the chance to study the blood of four ebola survivors to better understand how the immune system responds to the deadly virus, 6 aprill 2015,(vaadatud 8042015. Ebola, also known as ebola hemorrhagic fever or ebola viral disease, is a rare and deadly illness caused by one of the strains of ebola virus this viral agent is regarded as a prototype pathogen.

The filoviridae family consists of five known members, marburg, ebola zaire, ebola sudan, ebola reston, and ebola tai ebola virus is spread in a number of ways an outbreak starts when an infected animal or insect, called a vector, transmits the virus to a human. En la actualidad se conocen cinco especies del genero ebola virus: zaire ebolavirus, sudan was a strain of zaire ebolavirus, reston ebolavirus, sudan. The recently developed xpert® ebola assay is a novel nucleic acid amplification test for simplified detection of ebola virus (ebov) in whole blood and buccal swab samples the assay targets sequences in two ebov genes, lowering the risk for new variants to escape detection in the test the. In the three decades since the first reported case of ebola virus, most known index cases have been consistently traced to the hunting of bush meat, and women have consistently recorded relatively high fatality rates in most catastrophic outbreaks.

23 december 2016 - an experimental ebola vaccine was highly protective against the deadly virus in a major trial, according to results published today in the lancet the vaccine is the first to prevent infection from one of the most lethal known pathogens, and the findings add weight to early. A comparative study of strains of ebola virus pathogenesis of experimental ebola zaire virus certain pathogenetic characteristics of a disease in. Ebola virus are known [zaire ebola virus (zebov), sudan ebola virus (sebov), tai forest ebola virus, bundibugyo ebola virus (bebov), and reston ebola virus (rebov).

The ebola strain that is now circulating in west africa bears shows the homology of 97% with zaire ebola virus strains consist of four sudan ebola virus. The ebola virus causes an acute, serious illness which is often fatal if untreated ebola virus disease (evd) first appeared in 1976 in 2 simultaneous outbreaks, one in what is now, nzara, south sudan, and the other in yambuku, democratic republic of congo the latter occurred in a village near the. Ebola is a serious and deadly virus transmitted by animals and humans it was initially detected in 1976 in sudan and the democratic republic of congo researchers named the disease after the.
