For this #WormWednesday here's a species of ring nematode from Costa Rica called Xenocriconemella costaricense. This species of worm was found at a rainforest in La Cima de Copey de Dota, in the soil around the roots of wild avocado and Ecuador laurel. cambridge.org/core/journals/…

NUEVA PUBLICACIÓN! . Con alegría les comparto este nuevo artículo producto de mi tesis doctoral. Además, consideramos algunos especímenes colectados por Verónica Flores en Argentina. Journal of Helminthology

Dentro de los principales resultados encontramos una especie no descrita del género Trichobilharzia en el pato negro (Netta peposaca) y pato colorado (Spatula cyanoptera).

También registramos dos esquistosomátidos en el cisne de cuello negro (Cygnus melancoryphus), uno nasal y otro q corresponde a un nuevo género de esquistosomátido! Ambos ciclando con el caracol Chilina spp., lo cual ya describimos en un trabajo anterior, así como en Argentina.

Además, ampliamos la distribución geográfica de Trichobilharzia querquedulae a Chile y presentamos evidencia de nuevos caracteres morfológicos, mediante MEB, no descritos para esta especie, lo cual además podría tener implicancias para el diagnóstico del género completo!

Sin duda una emocionante colaboración con dos grandes helmintólogas que ya han hecho destacados aportes a este grupo: Verónica Flores y Sara Brant. . Referencias Oyarzún-Ruiz et al. (2024). DOI:10.1017/S0022149X2400035X cambridge.org/core/journals/…

Heterorhaditis is a bug-killing nematode. It can turn the insides of an insect into goop, then it reproduces in the insect's carcass. This paper reports on the virulence of six Heterorhabditis bacteriophora strains from the Azorean Archipelago cambridge.org/core/journals/…

Herbivorous mammals are often hosts to a wide range of gastrointestinal parasites including roundworms, tapeworms, and flukes This paper reviews the diversity and epidemiology of GI helminths across a wide range of wild ruminants in sub-Saharan Africa. cambridge.org/core/journals/…

Avian schistosomes usually infect birds, however their free-swimming larvae can cause a type of skin rash known as "swimmer's itch". This study reports on the morphology and life cycles of 4 different species of avian schistosomes from Chile and Argentina cambridge.org/core/journals/…

Senior author Dr. Sara Brant. One of two people who hooded me when I was awarded my doctorate and, more importantly, one of my first, and definitely most lasting, friendships (25 years! Ish) in #parasitology. 🪱 No one knows more about #avian #schistosomes, I’m convinced. 👇🏻

This is a CALL FOR PAPERS Molluscs are host to a wide range of parasites, and they play key roles at different stages of helminth life cycles. With that in mind we are putting together a special collection on helminths in molluscs.🐌 More details here: cambridge.org/core/journals/…

Mermithid nematodes usually parasitise terrestrial arthropods such as insects and spiders, but the species reported in this paper infects a marine crustacean. And not just any crustacean, but a tanaidacean in the genus Zeuxo #WormWednesday cambridge.org/core/journals/…

This study looked at the tapeworm communities of shrews from four islands in the Sea of Japan and the Sea of Okhotsk. The diversity of tapeworms on each island relates to the island's history, geographical features, and the presence of potential hosts. cambridge.org/core/journals/…

This study examined how environmental and host variables have shaped the tapeworm communities of blue sharks (Prionace glauca) at different locations. Researchers found that tapeworm composition varied by location and were constrained by host specificity. cambridge.org/core/journals/…

Spirometra erinaceieuropaei is a tapeworm that can use a range of animals as paratenic hosts, including fish, frogs, and snakes. This study investigated the prevalence of Spirometra larvae in snakes from the Hunan province in China. #WormWednesday cambridge.org/core/journals/…

The Areolate grouper (Epinephelus areolatus) is commonly found in coral reefs of the Indo-Pacific region, and is a commercially important species. This study looked at the parasite communities of this fish in Javanese and Balinese waters cambridge.org/core/journals/…

Taenia crassiceps can undergo asexual proliferation in their intermediate hosts - while convenient, it has its drawbacks. This study found that after years of being maintained through serial passages in lab mice, these tapeworms developed abnormalities. cambridge.org/core/journals/…

With >920 species, Hymenolepididae is an extremely speciose family of tapeworms. When researchers examined the phylogeny of hymenolepids from mammalians hosts, they found that these tapeworms have switched hosts between rodents and shrews multiple times. cambridge.org/core/journals/…

Schyzocotyle acheilognathi is an invasive fish tapeworm which is found in >300 species of fish around the world. In Australia, they are found in introduced fish species such as goldfish, koi, and mosquito fish and it may present a threat to native fishes. cambridge.org/core/journals/…

Ascaridia galli is a nematode worm that causes disease in chickens and turkey. In heavy infections, they may even end up in the bird's eggs. This paper describes an automated method for detecting and counting Ascaridia galli eggs in chicken faeces. cambridge.org/core/journals/…
