Tick-borne germs increasingly widespread in Canada: study

Published

 on

Researchers from Quebec and Ontario are calling for better testing to track the spread of tick-borne germs as disease-causing bacteria gain new ground in Canada.

Ticks are blood-sucking arachnids that can carry pathogens – bacteria, viruses and parasites – like those that cause Lyme disease. Now, McGill University PhD candidate Kirsten Crandall says pathogens that are local to other regions are beginning to show up across central Canada.

“While the bacteria that causes Lyme disease is the most common tick-borne pathogen in Canada, other tick-borne pathogens are moving in,” she said in a media release published on Nov. 17.

In a study published in the medical journal Vector-Borne and Zoonotic Diseases on Nov. 9, Crandall and her co-authors from McGill and the University of Ottawa warned that two pathogens, Babesia odocoilei and Rickettsia rickettsii, had been detected in Canada outside of their historic geographic range.

Babesia odocoilei causes a malaria-like parasitic disease called babesiosis. Babesiosis can be asymptomatic or it can cause flu-like symptoms, such as fever, chills, sweats, headache, body aches, loss of appetite, nausea or fatigue.

Rickettsia rickettsii causes Rocky Mountain spotted fever and anaplasmosis, and is normally found in the United States, Western Canada, Mexico, Panama, Costa Rica, Argentina, Brazil, Colombia and Bolivia.

Both bacteria can infect animals and humans, and both were found in ticks and small mammals in Quebec. According to the study, climate change, habitat fragmentation and changes in the abundance of tick populations and their hosts are all driving the spread of emerging tick-borne pathogens like these across Canada.

“The presence of these pathogens changes the risk of disease for Canadians and animals in some densely populated areas of Canada,” Crandall said.

Crandall and her team made the detections using methods that went beyond those normally used in tick monitoring studies. By testing ticks at all life cycle stages, they discovered that female ticks can actually pass pathogens to their larval young. They also tested for pathogens not already listed as nationally notifiable diseases in Canada.

She said the findings demonstrate the need for better testing and tracking to detect the spread and potential risk of tick-borne pathogens to humans and animals throughout the country.

“Only two tick-borne pathogens are listed as nationally notifiable diseases in Canada: Lyme disease and tularemia,” she said. “However, we are seeing increased cases of diseases like anaplasmosis and babesiosis in humans in Canada.”

Jeremy Kerr, a professor and research chair at the University of Ottawa’s department of biology, said the study highlights the importance of funding more research into tick-borne diseases that haven’t historically been common in Canada.

“If we don’t know that pathogens are present, we can’t equip Canadians with the information they need to protect themselves,” he said in a statement released on Nov. 17. “COVID has diverted public health resources away from challenges like this one, and we need to remember that these tick-borne diseases are on the move too.”

Christian McCaffrey is placed on injured reserve for the 49ers and will miss at least 4 more games

Published

 on

SANTA CLARA, Calif. (AP) — The San Francisco 49ers placed All-Pro running back Christian McCaffrey on injured reserve because of his lingering calf and Achilles tendon injuries.

The move made Saturday means McCaffrey will miss at least four more games after already sitting out the season opener. He is eligible to return for a Thursday night game in Seattle on Oct. 10.

McCaffrey got hurt early in training camp and missed four weeks of practice before returning to the field on a limited basis last week. He was a late scratch for the opener on Monday night against the Jets and now is sidelined again after experiencing pain following practice on Thursday.

McCaffrey led the NFL last season with 2,023 yards from scrimmage and was tied for the league lead with 21 touchdowns, winning AP Offensive Player of the Year.

The Niners made up for McCaffrey’s absence thanks to a strong performance from backup Jordan Mason, who had 28 carries for 147 yards and a touchdown in San Francisco’s 32-19 victory over the New York Jets. Mason is set to start again Sunday at Minnesota.

After missing 23 games because of injuries in his final two full seasons with Carolina, McCaffrey had been healthy the past two seasons.

He missed only one game combined in 2022-23 — a meaningless Week 18 game last season for San Francisco when he had a sore calf. His 798 combined touches from scrimmage in the regular season and playoffs were the third most for any player in a two-year span in the past 10 years.

Now San Francisco will likely rely heavily on Mason, a former undrafted free agent out of Georgia Tech who had 83 carries his first two seasons. He had at least 10 touches just twice before the season opener, when his 28 carries were the most by a 49ers player in a regular-season game since Frank Gore had 31 against Seattle on Oct. 30, 2011.

The Niners also have fourth-round rookie Isaac Guerendo and Patrick Taylor Jr. on the active roster. Guerendo played three offensive snaps with no touches in the opener. Taylor had 65 carries for Green Bay from 2021-23.

San Francisco also elevated safety Tracy Walker III from the practice squad for Sunday’s game against Minnesota.

Canada’s Newman, Arop secure third-place finishes at Diamond League track event

Published

 on

BRUSSELS – Canada walked away with some hardware at the Diamond League track and field competition Saturday.

Alysha Newman finished third in women’s pole vault, while Marco Arop did the same in the men’s 800-metre race.

Newman won a bronze medal in her event at the recent Paris Olympics. Arop grabbed silver at the same distance in France last month.

Australia’s Nina Kennedy, who captured gold at the Summer Games, again finished atop the podium. Sandi Morris of the United States was second.

Newman set a national record when she secured Canada’s first-ever pole vault medal with a bronze at the Olympics with a height of 4.85 metres. The 30-year-old from London, Ont., cleared 4.80 metres in her second attempt Saturday, but was unable conquer 4.88 metres on three attempts.

Arop, a 25-year-old from Edmonton, finished the men’s 800 metres with a time of one minute 43.25 seconds. Olympic gold medallist Emmanuel Wanyonyi of Kenya was first with a time of 1:42.70.

Djamel Sedjati, edged out by Arop for silver in Paris last month, was second 1:42.87

Bologna prepares for Champions League debut with draw at Como while Juventus held

Published

 on

MILAN (AP) — Bologna’s preparations for its Champions League debut are not going well though it managed to spoil Como’s first Serie A home match in 21 years on Saturday.

Bologna came from two goals down to salvage a 2-2 draw to gather three points from its opening four matches.

Bologna hosts Shakhtar Donetsk on Wednesday. Its only other appearance in Europe’s top competition was in 1964 in the preliminary round of the old European Cup.

AC Milan is also winless as it prepares for a Tuesday Champions League match against Liverpool. The Rossoneri hosted promoted Venezia later. Juventus drew at Empoli 0-0.

Como made a great start in the fifth minute when Patrick Cutrone attempted to roll the ball across the six-yard box but it took a huge deflection off Bologna defender Nicolò Casale for an own goal.

Bologna thought it was gifted a way back into the match on the stroke of halftime when referee Marco Piccinini signalled for a penalty following an Alberto Moreno handball, but he revoked his decision and instead gave a free kick because the handball was just outside the area.

Bologna improved after the break but found itself further behind when Cutrone raced onto a through ball and cut inside past a defender and fired into the far bottom corner.

Tommaso Pobega hit the post for Bologna, which finally pulled one back in the 76th through substitute Santiago Castro.

Another substitute helped the visitors snatch a point when Samuel Iling-Junior curled a fine strike into the top left corner in stoppage time.

Unbeaten sides

Juventus, and more surprisingly Empoli, are among six unbeaten sides.

Empoli held Monza and Bologna to draws either side of a shock 2-1 win at Roma. Juventus’ perfect start to the season was ruined by Roma in a goalless draw before the international break.

On Saturday, there were few clearcut chances in Empoli although home goalkeeper Devis Vásquez made spectacular saves to fingertip out a Federico Gatti header and deny Dusan Vlahovic in a one on one with the Juventus forward.

Empoli had a good opportunity in the 73rd minute following an Alberto Grassi one-two with Pietro Pellegri but the finish was straight at Mattia Perin.

The host could have won it right at the death but Gatti flew in with a great sliding block to keep out Emanuel Gyasi’s close-range effort.

Juventus hosts PSV Eindhoven in the Champions League on Tuesday.
