Transgenic mosquitoes transfer genes to native mosquito species

Transfer of genes from genetically-modified Aedes aegypti mosquitoes to naturally-occurring ones were seen in Brazil where transgenic mosquitoes were released from June 2013 to September 2015. Contrary to claims made, genes from genetically-modified Aedes aegypti mosquito were found to have been transferred to naturally-occurring A. aegypti mosquito population in three areas in Brazil where transgenic mosquitoes … Continue reading Transgenic mosquitoes transfer genes to native mosquito species

NBRC-led team deciphers how Zika virus causes microcephaly

The NBRC-led team of researchers has identified the molecular and cellular mechanisms by which Zika virus causes microcephaly. The envelop protein of the virus was responsible for arresting the proliferation of human foetal neural stem cells and also killing the cells that were becoming neuron-like. The combined effect reduces the pool of foetal brain cells leading to … Continue reading NBRC-led team deciphers how Zika virus causes microcephaly

IIT Roorkee finds a potent antiviral molecule to treat chikungunya

Of the two small molecules tested, IIT Roorkee researchers have found one of them has good antiviral activity against chikungunya virus. The small molecule was able to achieve almost 99% reduction in the virus when 5 microMolar of the molecule was used. The molecule is highly specific to chikungunya virus. A team of researchers at the Indian … Continue reading IIT Roorkee finds a potent antiviral molecule to treat chikungunya

Manu Prakash makes mosquito surveillance using mobile phones possible

Dr. Manu Prakash is once again at his best — solving complex problems in an extraordinarily simple fashion. Using wingbeat sound, location and time of recording, Dr. Prakash and his team from Standford University hope to make real-time global maps of mosquito distributions, which could help design better strategies to control mosquitoes and combat mosquito-borne diseases. … Continue reading Manu Prakash makes mosquito surveillance using mobile phones possible

IIT Roorkee team repurposes a drug for chikungunya

The Piperazine drug used for treating worm infections and HIV has been able to inhibit the replication of chikungunya virus by nearly 98%. A drug to treat chikungunya virus infection is in the offing, and in vitro studies carried out by a team of researchers from the Indian Institute of Technology (IIT) Roorkee show promise. Currently, there … Continue reading IIT Roorkee team repurposes a drug for chikungunya

The Asian Zika virus strain turns out to be more dangerous

The Asian strain showed greater ability to trigger immune suppression, which allows the virus to replicate and even possibly sneak into the womb and cause more foetal damage. Clinical studies have already shown that infection of pregnant women by the Asian Zika virus strain especially during the first and second trimester of pregnancy leads to … Continue reading The Asian Zika virus strain turns out to be more dangerous

Bharat Biotech has begun chikungunya vaccine Phase I trial

The Hyderabad-based Bharat Biotech has begun a Phase I human clinical trial of the indigenously developed chikungunya vaccine three months ago. The vaccine uses a killed virus. The Phase I trial will test mainly for safety and the ability of the vaccine to provoke an immune response in the body. The higher the immune response … Continue reading Bharat Biotech has begun chikungunya vaccine Phase I trial

Wolbachia-infected mosquitoes less capable of spreading Zika, chikunguya

With conventional vector controlling measures against dengue- and Zika-causing Aedes aegypti mosquitoes failing, several countries have started caged and even open field trials using genetically modified mosquitoes. India has signed a Memorandum of Understanding with Monash University for using Wolbachia-infected A. aegypti mosquitoes for vector control. Dengue, Zika or chikunguya viruses cannot replicate when mosquitoes have been infected … Continue reading Wolbachia-infected mosquitoes less capable of spreading Zika, chikunguya

Seventy-year journey of Zika virus

Zika is an arbovirus infection which occurs through the bite of several different species of Aedes mosquitoes, including the Aedes aegypti which is active during the day; it can also be transmitted sexually. The virus was first isolated from a rhesus monkey in Uganda in the Zika forest, near the western shore of Lake Victoria, … Continue reading Seventy-year journey of Zika virus

Ridiculous excuse for India’s shocking cover-up of Zika virus cases

It may well be said that the surveillance system put in place by the Health Ministry achieved a measure of success in identifying three adults who were infected with the Zika virus between November 2016 and February 2017 in Gujarat. Yet, the Ministry acted extremely irresponsibly by withholding the information from the local administration, doctors and the media. … Continue reading Ridiculous excuse for India’s shocking cover-up of Zika virus cases
