Estudian el impacto de la miasis en la ganadería argentina - INTA Informa. Un equipo de investigación del INTA, del Conicet y de la Facultad de Ciencias Agropecuarias (Universidad Católica de Córdoba) realizó el primer relevamiento sobre el impacto de esta parasitosis en los rodeos del país. Causada por el díptero "Cochliomyia hominivorax", la miasis en el ganado provoca una disminución en la producción de carne, leche y lana, lo que ocasiona pérdidas económicas significativas. La miasis se define como la infestación de animales vertebrados con larvas de dípteros, las cuales durante un cierto período se alimentan de los tejidos del hospedador. Si bien diferentes especies de dípteros pueden provocar miasis, en la Argentina la más común es causada por Cochliomyia hominivorax y afecta a los animales vertebrados de interés productivo, a los silvestres y, ocasionalmente, al hombre. En cuanto a las causas que predisponen la aparición de la infestación en bovinos adultos aparecen: los partos, las garrapatas y las heridas.
PARASITES & VECTORS 07/01/21 New World screwworm (Cochliomyia hominivorax) myiasis in feral swine of Uruguay: One Health and transboundary disease implications. To the authors’ knowledge, this is the first epidemiological report of screwworm myiasis in feral swine from South America. The myiasis cases in feral swine were reported by hunters in the Artigas and Salto provinces of Uruguay between April 2017 and April 2020. Of the 618 swine examined, 27 were infested with maggots. The screwworm infestation prevalence (4.36%) recorded in the feral swine captured in this study is relatively higher than the estimated 2–3% in wildlife reported by Lindquist in 1937 in Texas , and lower than the > 5% recorded in domestic pigs in 1987 in Yucatan, Mexico . The prevalence reported here is similar to that reported previously in sheep (5.7%) and cattle (3.4%) in Uruguay . Screwworm cases were detected primarily in large male feral swine, and primarily in wounds that the hunters suspected as being the result of fighting between males.
Feral swine that survive infestation could play an important role in the dissemination of screwworm.

THE ATLANTIC 26/05/20 America’s Never-Ending Battle Against Flesh-Eating Worms (Lucilie bouchère) - Inside the U.S. and Panama’s long-running collaboration to rid an entire continent of a deadly disease. The Florida Keys are a place where deer stand next to children at school-bus stops.
They lounge on lawns. They eat snacks right out of people’s hands. So when the deer began acting strangely in the summer of 2016, the people of the Keys noticed. Bucks started swinging their heads erratically, as if trying to shake something loose. Then wounds opened on their heads—big, gaping wounds that exposed white slabs of bone. That something, lab tests would later confirm, was the New World screwworm, a parasite supposed to have been eradicated from the United States half a century ago. Screwworms once killed millions of dollars’ worth of cattle a year in the southern U.S. For untold millennia, screwworms were a grisly fact of life in the Americas. Read: The ‘golden death’ bacterium found in a rotten apple To get the screwworms out, the USDA to this day maintains an international screwworm barrier along the Panama-Colombia border. The insect is relentless in its search for hosts. UNIVERSITY OF NEBRASKA - 2005 - Quality of Transgenic Laboratory Strains of Cochliomyia hominivorax (Diptera: Calliphoridae)
Abstract Genetically modified, mass reared insects present novel possibilities for the future of insect control. One concern about manipulation of insects is a possible loss of strain quality due to the introduction of a foreign gene of any sort into the insect genome. Eight transgenic strains of screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), were compared with the wild-type parental laboratory strain in laboratory culture. Measurements of average fertility, fecundity, larval productivity, and longevity were analyzed.
Two transgenic strains had significantly lower larval productivity than controls, one of which was explained by a homozygous lethal insertion of the transgene. Another strain produced significantly fewer eggs than controls. Overall strain characteristics, including measurements from egg, larva, pupa, and adult stages, were compared. FRONT. MED. 22/01/20 Umbilical Myiasis by Cochliomyia hominivorax in an Infant in Colombia. Introduction Myiasis is infestation by fly larvae (Diptera) in live vertebrates, including humans. Fly larvae feed on wound tissue of their host, causing a disease whose severity may depend on the larva species and anatomical sites affected (1, 2). It is widespread in neotropical areas around the world, causing economic and public health problems in low-income populations. Human infection is facilitated by poor hygienic conditions and close contact with wild or domestic animals (2, 3). Umbilical cord myiasis is a common type of wound myiasis in animals but it has been described only rarely in humans (2).
We present the first report of neonatal umbilical myiasis in Colombia and review the most relevant aspects of this disease. Case Report The research procedures for this case were carried out in accordance with the recommendations of the guidelines of the Helsinki Committee. The neonate was transferred to a tertiary care hospital. Discussion Table 1. Ethics Statement Author Contributions 1.

“This had not been around since the ’50s and ’60s,” said Dan Clark, the manager of the refuge. “My staff wouldn’t have worked professionally with anything like that. Even a lot of veterinarians just had never seen it,” he said, adding, “Any reasonable person would have done what we did.” To eradicate the screwworm, seven million fly pupae sterilized by radiation are being released each week in the Florida Keys. The female mates only once in her lifetime, so the idea is that if the female mates with a sterilized fly, the screwworm infestation should be over in about six months. For the first time since the outbreak began, no deer died in the past week, showing that those measures and antiparasitic medications fed to the deer are beginning to show signs of success, the Fish and Wildlife Service said in a statement on Thursday.

In July 2013 a British woman came to the attention of both the medical community and the media when she returned from Peru with maggots in her ear. The fly larvae had created a cavity connected to the ear canal and were feeding on healthy tissue in Rochelle Harris's head.
According to a Medical Daily story by John Ericson, Harris endured “unbearable pains emanating from one side of her face, pains that were eventually accompanied by menacing scratching sounds from inside her head” ("British Woman Discovers Flesh-Eating Maggots Inside Her Ear," July 16, 2013). This is a horrific story, and many people reading it will have heard of the dreaded New World screwworm fly – Cochliomyia hominivorax - for the first time. In North America, too, we're unfamiliar with the fly - we've forgotten that it once infested the southern United States, spreading northward each summer as far as Canada.

Federal agriculture officials reported Monday on the first local infestation of New World screwworm in the United States in at least three decades. Screwworm larva/ Agricultural Research Service According to the United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) the presence of New World screwworm in Key deer from a wildlife refuge in Big Pine Key, Florida was confirmed.
Florida Commissioner of Agriculture Adam H. Putnam declared an agricultural state of emergency in Monroe County. “The screwworm is a potentially devastating animal disease that sends shivers down every rancher’s spine. In addition to the samples from three Key deer that were confirmed positive for screwworm, there are other Key deer from the same refuge and a few pets in the local area that exhibited signs of screwworm over the past two months, though no larvae were collected and tested in those cases.

Afin d'identifier les maladies exotiques les plus à risque d'introduction en France et de préciser les modalités de lutte et de surveillance les plus adaptées contre ces agents, l'Anses s'est auto-saisie.
Elle publie aujourd'hui les résultats de ses travaux et les recommandations qu'elle en tire. La santé des animaux est susceptible d'être menacée par divers agents pathogènes (bactéries, virus, parasites) dont certains peuvent également affecter la santé humaine (agents zoonotiques). Dans ce contexte, l'Anses a souhaité s'autosaisir. L'étude de l'Anses a porté sur les maladies des bovins, des petits ruminants, des porcs, des chevaux et des volailles. Recommandations de l'Anses.
