The flax wilt agent has been sequenced

(St. Petersburg State University) Fusarium wilt is a nasty but common disease affecting economically important crops such as banana, cotton, flax, canola, melons, onions, potato and tomato. The release of the complete genome sequence is a milestone in comparative genomics studies of fungal parasites; it contributes to the global efforts aimed at elimination of plant disease outbreaks by aiding in engineering of new resistant crops varieties.

Infectious disease outbreaks are causing widespread declines of marine invertebrates including corals, sea stars, shrimps, and molluscs. Dermo is a lethal infectious disease of the eastern oyster Crassostrea virginica caused by the protist Perkinsus marinus. The Pacific oyster Crassostrea gigas is resistant to Dermo due to differences in the host-parasite interaction that is not well understood. We compared transcriptomic responses to P. marinus challenge in the two oysters at early and late infection stages. Dynamic and orchestrated regulation of large sets of innate immune response genes were observed in both species wit...

J Vector Borne Dis. 2021 Jan-Mar;58(1):1-11. doi: 10.4103/0972-9062.318313.ABSTRACTIncreased outbreaks of mosquito borne diseases like the deadly parasitic disease, malaria and arboviruses like Zika, yellow fever and dengue viruses around the world have led to increased interest in traps that could effectively be used against mosquitoes. For example, a Google search at the time of this writing, asking, 'which is the best way of trapping mosquitoes?' produced 35.5 million search results. Regardless of the interest in the subject, scientists have yet to find a definitive answer to these questions. One area that has been expl...

Theileria annulata, which causes tropical theileriosis, is a major impediment to improving cattle production in Sudan. Tropical theileriosis disease is prevalent in the north and central regions of Sudan. Outbreaks of the disease have been observed outside the known endemic areas, in east and west regions of the country, due to changes in tick vector distribution and animal movement. A live schizont attenuated vaccination based on tissue culture technology has been developed to control the disease. The parasite in the field as well as the vaccine strain need to be genotyped before the vaccinations are practiced, in order t...

CONCLUSIONS: During the COVID-19 outbreak, the risk of schistosomiasis increased due to snail colonies returning to their sites of origin in Wuhan, suggesting a need for strengthened infection control and prevention measures.PMID:34757041 | PMC:PMC8575659 | DOI:10.1016/j.actatropica.2021.106224

Dr Ijaz Ali has spent the last 11 years persuading the authorities to use genetically engineered mosquitoes to fight dengue fever. The health department, however, is concerned about unforeseen circumstances that could arise from this method. By Zofeen EbrahimKarachi , Nov 2 2021 (IPS) Twenty-three-year-old Sarah Tajammal felt a sense of “impending doom” as she fought high fever, nausea, bouts of vomiting and extreme fatigue after being diagnosed with dengue two weeks back. Living in Lahore’s DHA area, which has reported the most dengue cases “because of the damp green environment”, she may ha...

Online ahead of print.ABSTRACTThe protozoan parasites Cryptosporidium and Giardia are significant causes of diarrhoea worldwide and are responsible for numerous waterborne and foodborne outbreaks of diseases. Over the last 50 years, the development of improved detection and typing tools has facilitated the expanding range of named species. Currently at least 44 Cryptosporidium spp. and>120 genotypes, and nine Giardia spp., are recognised. Many of these Cryptosporidium genotypes will likely be described as species in the future. The ph...

In this study, we performed a thorough comparison, in terms of assembly quality and purity, of 100+ de novo assembled genomes of C. hominis. Remarkably, after quality genome filtering, a comprehensive phylogenomic analysis allowed us to discover that C. hominis encompasses two lineages with continental segregation. These lineages were named based on the observed continental distribution bias as C. hominis Euro-American (EA) and the C. hominis Afro-Asian (AA) lineages.

On Oct. 6, the World Health Organization recommended use of the first vaccine to fight malaria. The decision is momentous and highly anticipated for many reasons: among them is that this is the first vaccine to help reduce the risk of deadly severe malaria in young children in Sub-Saharan Africa, where the disease remains a leading killer. The vaccine offers hope that there can be a circle of learning from one pandemic to the next. Malaria, our oldest pandemic, may offer insights on how we can survive contemporary scourges like COVID-19. Malaria evolved at least 2.5 million years ago and first infected humans in rural part...
