New malaria parasite discovered in bonobos

first_imgResearchers monitoring African bonobos have found the animals to be playing host to a previously unknown malaria parasite.Though malarial parasites are known to be endemic in African chimpanzees and gorillas, the parasite has not been found in wild bonobos. The absence has previously been described as a mystery, because bonobos should be just as susceptible to various Plasmodium parasites as other non-human primates, and malaria has been described in captive populations of the animals.Now, by sampling more bonobos in geographically diverse settings, scientists writing in Nature Communication show that bonobos harbor a new species of malaria parasite, called Plasmodium lomamiensis. The parasite is a previously unknown Laverania species, which are closely related to P falciparum, one of the parasites that causes human malaria infections.The researchers tested 1,556 fecal samples from 11 sites along the rain forests of the Congo Basin in the Democratic Republic of the Congo (DRC). They found high levels of Laverania in a remote area called Tshuapa-Lomami-Lualaba in the eastern part of the DRC.”Not finding any evidence of malaria in wild bonobos just didn’t make sense, given that captive bonobos are susceptible to this infection,” said Beatrice Hahn, MD, a professor of microbiology in the Perelman School of Medicine at the University of Pennsylvania, in a press release.In addition to finding P lomamiensis, the researchers also isolated P gaboni, formerly found only in chimpanzees, in bonobo samples from the remote area. But they were surprised that the bonobos carrying the parasite were so geographically isolated.”Analyses of climate data and parasite seasonality, as well as host characteristics, including bonobo population structure, plant consumption and faecal microbiome composition, failed to provide an explanation for this geographic restriction,” the authors write. “Thus, other factors must be responsible for the uneven distribution of bonobo Plasmodium infections, including the possibility of a protective mutation that has not spread east of the Lomami River.”Understanding what, if any protective mutations might be guarding most African bonobos from malaria could be a key insight into how the parasite can be eliminated from human populations, the researchers wrote.Insight into human malarial diseaseHahn and her co-authors suggest that wider testing of bonobos and all non-human primate species in Africa should be undertaken to predict how various malarial parasites could infect human populations.”While ape Laverania parasites have not yet been detected in humans, it seems clear that the mechanisms governing host specificity are complex and that some barriers are more readily surmountable than others,” the authors write. “Given the new bonobo data, it will be critical to determine exactly how P. praefalciparum was able to jump the species barrier to humans, in order to determine what might enable one of the other ape Laverania parasites to do the same.”See also:Nov 21 Nat Commun studyNov 21 University of Penn press releaselast_img read more

Oceanology International: UK Govt approves exhibitions from October 1, 2020

first_imgOi and ExCeL London have been working with the AEV (Association of Event Venues) and other key stakeholders to develop the All Secure Standard, an industry-wide benchmark to enable the safe return of organised events. Although around 10% of the venue will remain as storage for the NHS Nightingale hospital set up at ExCel during the pandemic, the vast majority of the venue (90%) has been restored to its original state, allowing the venue to fully function within the security of the new guidelines. The UK Government have announced that from October 1st, 2020 B2B exhibitions will once again be held in England. This much-anticipated news opens the doors for domestic and international business delegates from around the world to meet and share ideas, renew essential contacts and further innovation. Oceanology International (Oi) 2020 is set to take place at ExCel London from 1-3 December 2020, which will make it one of the first major industry events to occur since the start of the COVID-19 pandemic led countries around the world into lockdown. Oi 2020 will benefit visitors from around the world with an unmissable and diverse range of ocean technology and innovation, on-water demonstrations and technical conference content, ideal to help re-establish ocean businesses in the context of the ‘new normal’. “We look forward to welcoming everyone to London in December to resume first-hand experiences and conversation, and will work tirelessly to ensure that exhibitors, delegates and visitors are kept safe and secure through strict adherence to current government and medical advice.” “Organisers, venues and suppliers have worked tirelessly to create COVID-19 safe guidelines which create the framework for the safe re-opening of exhibitions in a COVID-secure way,” he continued. “These include, but are not limited to, the ability to track and trace our audiences and create bespoke events on a risk-assessed basis.” The UK Government have announced that from October 1st, 2020 B2B exhibitions will once again be held in England (Image Courtesy: Oceanology International) Throughout the pandemic, the Oi Portfolio has delivered a wide variety of content to help keep the industry connected and informed via the Inside Oi Hub, which was launched in April creating an online resource filled with webinars, blogs and videos designed to assist all aspects of the industry.center_img The announcement follows a long period of intensive negotiations between the UK Government and the Association of Event Organisers (AEO) – of which Oi organisers Reed Exhibitions is a member – together with the Association of Event Venues (AEV) and the Event Supplier and Services Association (ESSA). Chris Skeith, AEO CEO, said: “We are pleased to see that – after months of constructive conversations with the government – a ‘go date’ has been issued for the exhibitions industry, which plays a critical role for the UK economy, generating £11bn in economic activity and supporting 114,000 jobs. Author: Baibhav Mishra To assist exhibitors and visitors in understanding and preparing for exhibitions under the new framework, Reed Exhibitions have developed a ‘new normal’ guide, which is available here. Sea News, July 29 David Ince, Event Director, Oceanology International, said: “This is great news for the hundreds of companies we support and facilitate connections for, as well as the events industry. After some challenging times for all of us, having the opportunity to bring expertise together from all over the world in an innovative and collaborative business environment will be a great way to finish the year.last_img read more

Oyama stretches lead at Salonpas World Ladies

first_imgThe money leader on the Japan LPGA tour rebounded from bogeys on the first and ninth holes with birdies at Nos. 11 and 16 before failing to save par on the par-5 17th for another dropped shot.“I wanted to pick up some strokes even in such difficult conditions but I’m satisfied with where I am and with this score of 5-under,” said Oyama, who is aiming for her second title in three weeks following her victory at the Fujisankei Ladies Classic.The 28-year-old, who finished third behind Yuri Fudo and Ai Miyazato on the 2005 money list, has won four tour events in her career. She leads this year’s money rankings with 29.2 million yen in official earnings, to 27.3 million yen for second-place Fudo, the top earner on the tour the previous six years.Akane Iijima and Akiko Fukushima both shot 72s and climbed into a tie for second at even-par 216.First-round leader Momoko Ueda, who began the day one stroke behind Oyama, dropped into a six-way tie for third after struggling to a 78 that included five bogeys in the final six holes.Joining Ueda at 217 are South Korea’s Shin Hyun Ju, Nahoko Hirao, Kuniko Maeda, Ai Ogawa and Miho Koga.Sakura Yokomine fired a 72 and is another stroke back at 218, while U.S. LPGA star Paula Creamer matched the day’s low with a 71 and moved into a tie for 13th at 3-over 219. Creamer, who won both of her previous two tournaments in Japan, was one of only three players who broke par for the day.Defending champion Fudo is tied with Creamer after a 74.The winner of the 72-hole tournament will earn 18 million yen out of the 100 million yen purse. Overnight leader Shiho Oyama played patiently in blustery conditions Saturday and stretched her lead to five shots going into the final round of the Salonpas World Ladies.Oyama, who took a one-stroke lead after shooting a 66 on Friday, fired a 1-over-par 73 on a day when strong winds sent scores soaring at Tokyo Yomiuri Country Club and stayed on top of the leaderboard on 5-under 211 after three rounds.

The date, time and location of the game will be announced later.After stopping Marquette’s opening drive on fourth down on the Redmen 36, Muskegon needed only four plays before Martinez scored from three yards out, and the extra point put Muskegon up 7-0 just 3:18 into the game.Cameron Martinez reaches across the goal line to score a TD for Muskegon. Photo/Craig SmithMartinez added rushing touchdowns of eight and fours yards as the Big Reds took a 21-0 lead after one quarter – and he was just getting started.“”You have a different mindset coming into the postseason,” Martinez said. “Be aggressive, because you don’t want to have any regrets at this time of year.”The Redmen had seven rushes for 17 yards and four incomplete passes on their first three possessions, but found success on drive number four.Marquette quarterback Robert Apple went 3-for-4 passing on the opening drive of the second quarter, and found Kameron Karp behind the Big Reds’ defense for a 53-yard TD pass to cut the lead to 21-7 with 10:53 left in the half.“I definitely felt like we were flat at times,” Muskegon coach Shane Fairfield said. “When you have a team down, you want to step on their throat. It didn’t feel like we had that instinct like we had the last few games.”Any unease for Big Reds fans quickly faded when Martinez added a 27-yard touchdown run just 1:59 later, increasing the lead to 28-7.Muskegon senior Kolbe Lewis breaks free for a big gain. Photo/Craig SmithKolbe Lewis’ interception on Marquette’s next play set Muskegon up with another short field. Martinez scored from 31 yards, and the Big Reds had a 35-7 lead with 7:06 left in the second quarter.Martinez finished his day with TD runs of 87 and 10 yards, giving Muskegon a 48-7 halftime lead.“Our offensive line has been dominating all year and makes it easy for us,” Martinez added. “We’re just focused on getting better and surviving and advancing.”The senior QB’s only play of the second half was the first one, a handoff to Robert Gee Jr., who took it 71 yards for a touchdown and a 55-7 lead just 56 seconds into the third quarter.Junior Amari Crowley took over for Martinez after that and added a four yard TD run to end the third quarter, and a 59-yard scoring burst with 5:51 left in the game.Muskegon finished with 588 total yards of offense, including 555 rushing yards on 34 carries.Tommy Watts had eight carries for 78 yards for the Big Reds, Japrie Henderson added 40 yards on four carries and Crowley carried the ball twice for 63 yards.Lewis and Tre’von Cosse had interceptions for Muskegon and Julius Sims recovered a fumble as the defense held Marquette to 171 yards, including just 39 on the ground.
