Maryland, My Maryland

Reuters, U.S. confirms nation's first travel-associated human screwworm case connected to Central American outbreak 

The U.S. Department of Health and Human Services on Sunday reported the first human case in the United States of travel-associated New World screwworm, a flesh-eating parasite, from an outbreak-affected country.

The case, investigated by the Maryland Department of Health and the U.S. Centers for Disease Control and Prevention, was confirmed by the CDC as New World screwworm on August 4, and involved a patient who returned from travel to El Salvador, HHS spokesman Andrew G. Nixon said in an email to Reuters.

Earlier, Reuters reported that beef industry sources said last week that the CDC had confirmed a case of New World screwworm in a person in Maryland who had traveled to the United States from Guatemala. Nixon did not address the discrepancy on the source of the human case.

"The risk to public health in the United States from this introduction is very low," he said.
The U.S. government has not confirmed any cases in animals this year.

The differing accounts from the U.S. government and industry sources on the human case are likely to further rattle an industry of cattle ranchers, beef producers and livestock traders already on high alert for potential U.S. infestations as screwworm has moved northward from Central America and southern Mexico.

The government's confirmation of a screwworm case comes just over a week after U.S. Department of Agriculture Secretary Brooke Rollins traveled to Texas to announce plans to build a sterile fly facility there as part of efforts to combat the pest.

The USDA has estimated a screwworm outbreak could cost the economy in Texas, the biggest U.S. cattle-producing state, about $1.8 billion in livestock deaths, labor costs and medication expenses.

Whatever you do, do not google images of screwworm infestations. I'm familiar with Botfly occurrences in squirrels, and have heard of rare cases in human. Our dear departed cat Felicity once got a warble in Oregon. Gross, but multiply that by a 100 or more for Screwworms.

I'm just going to hazard a guess that the "Maryland Man" with the Screwworm was anything but a Maryland man, which would explain the confusion between El Salvador and Guatemala.

Scientists Appreciate Oyster Parasites

WYPR News, These parasites are a good thing… especially if you’re a Chesapeake Bay oyster reef

Fat mollusks, rockfish and even parasites can be found thriving at oyster sanctuaries in three Chesapeake Bay tributaries, leading scientists to believe that current oyster restoration techniques are working.

Those findings are detailed in a newly released study from the Smithsonian Environmental Research Center and University of North Carolina at Chapel Hill which found more wildlife diversity at sanctuaries than nearby unprotected harvest sites.

One indication of that — two native parasites: the boring sponge and mud blister worm.

They win their names easily enough. The boring sponge drills or “bores” through the shell to make a home while the mud blister worm burrows into the inner shell causing the oyster to form darkened, muddy-looking patches around the worm in self-defense.

“I think a knee jerk reaction for people is to be like, ‘Oh, that's bad, right?’” said lead report author Zofia Beck Anchondo. “But parasitism is the most common ecological relationship and that means that if there are more parasites, that is suggestive that there are more of other things.”

Essentially, they’re a sign of good ecosystem health.

And in their research, which was conducted over the summer of 2019, scientists did find more wildlife like blue crabs, rockfish and summer flounder at the sanctuaries than at unprotected harvest sites. They also found fewer parasites at the harvest sites.

Anchondo and her co-hort say those findings are an indication that the sanctuary restoration projects are working to improve oyster health and numbers. Oysters are the “backbone” of the Chesapeake Bay, they say, as they both filter water and support marine life as a food source and habitat. Due to overharvesting, pollution and disease, the oyster population in the Bay is likely around 1% of its historic levels.

Researchers collected samples from three Chesapeake tributaries: the Choptank River, the Great Wicomico River and the James River. Each site had both an oyster sanctuary and nearby harvest site, where the mollusks can be freely taken, for comparison.

The results aren’t surprising for Matt Ogburn, a co-author and senior scientist with the Smithsonian Environmental Research Center, but they are reassuring.

“For the first time since the science of ecology was founded, we have oyster reefs that are relatively large scale to study,” he said. “ It's really exciting to be able to see now, using data, that the restored reefs are performing the way that we think they should with larger numbers of oysters, better habitat and more species and animals living on them.”

The presence of the parasites are remarkable for a few reasons. While they take a toll on the energy of the individual oyster, they do not kill it.

“They’re not preventing high oyster densities,” said Matt Ogburn, and while more research is necessary, there’s even a possibility that the parasites are good for the oysters’ long-term evolution, he added.

“Restoring the oyster reefs is likely to be helping the oyster population become more resilient to the parasites that are out there now, compared to what would be possible if everything was harvested all the time.”

Evidence of these native parasites go back hundreds of years, Anchondo pointed out. Previous studies on Chesapeake-area shell middens, which are essentially trash dumps from earlier humans, indicate the presence of those parasites, particularly the boring sponge.

I'm sure if you looked hard enough you could find fossil oyster shell beds dating prior to human occupation of the North America that would show boring sponge and mud blister worm signs.

Big Fish Have Little Bugs Upon Their Back to Bite Them

Chesapeake Bay Mag, Unknown Parasite Latching Onto Stripers, Other Fish

During the last few months, anglers have been catching fish in the Chesapeake with parasites attached to their bellies and fins. Striped bass and sheepshead are the most frequent hosts. One sheepshead was found carrying over 20 of the unsavory hitchhikers. Some on social media believe the parasites are simply sea lice, but that is not the case.

Hamish Small, an Associate Research Scientist at the Virginia Institute of Marine Science (VIMS) who earned his doctorate in Marine Parasitology, reports that, “sea lice are parasitic copepods, and these (recent infestations) appear to be an iparasitic sopod (crustacean).” Small is sequencing the DNA of these crustaceans so he can determine exactly what they are. If he had to guess, Small believes they are Livoneca redmanii, which are known to be in the Chesapeake Bay. One particularly gross version of these parasites is Cymothoa exigua, which once inside the fish’s mouth attaches to the tongue of the host fish, and eventually replaces the tongue!

We do occasionally see the "tongue eating" parasite, more often in blue fish and Menhaden than Striped Bass.

According to Small, it is not unusual to find a fish that is carrying a few of these parasites. It is the recently discovered larger numbers of parasites on individual fish that is a cause for concern. “They usually are found in small numbers (single or a pair) within the buccal cavity (mouth) or in the gill chamber of the fish they parasitize, so the current finding of multiple (over 20) on the caudal fin (tail) and caudal peduncle (the narrow part of a fish forward of the tail) of the sheepshead is somewhat unusual. Likewise, another case indicated eight parasites attached to the pelvic fins of a striped bass,” he said.

 There are also small parasitic copepods that infect fish gill, especially Striped bass, in warmer and more brackish water. They can't be good, but they don't seem particularly associated with sick looking fish. Most fishermen don't even know they are there 

These parasites use hooks to hold onto their hosts. That cannot be comfortable, especially in the mouth. Heavy infections, such as on the sheepshead, can cause significant damage to the host fish. Can you eat an infected fish? VIMS said there is no harm to humans. Personally I would donate an infected fish to science and catch another for dinner.

“At this point we can’t really say whether this is something new.” said Small. If it is new, the scientists at VIMS don’t know the cause. If you are an angler, you can help by reporting any infected fish you catch. Try to get a photo, and call VIMS at 757 787-5834.
The fish we catch here in winter and early spring commonly have some kind of isopod on them, and most fisherman call them "sea-lice", which probably just reflects the problem with common names. Most fisherman also think that they are a sign that the fish has recently migrated in from the ocean, although Pete and me are starting to doubt that. Often, after having caught a few fish, the deck is littered with the things crawling around. They certainly wouldn't discourage me from eating the fish.

Cooties from Selfies?

. . .Samples from 30 states, including Texas, found a gene mutation in lice that turns it into a superbug and resistant to over-the-counter chemicals.

If that's not bad enough, there is also a new way adults and teens are getting it: selfies.
Lice used to be a childhood problem eventually outgrown, like when youngsters bumped heads as they played together in tight quarters.
There used to be an old way of showing how radioactive contamination works. Put a fluorescent white powder on a sign in sheet at a radiation safety seminar. At the end of the session, break out a UV light.  A similar approach might work here.
Now, as adults and teenagers almost constantly put their heads together while taking selfies, they’re unknowingly giving lice a new host on which to feed.

Loren Hickman works at Hair Fairies in Dallas, which specializes in lice removal. She says it's impossible to pinpoint exactly where someone gets lice.

However, Hickman says she's seen an uptick in the number of teens with lice who don't have siblings.

“They're holding the phone up, putting their head close to their friend,” said Hickman. “It only takes a second.”
Damn jumping lice. . .
