We've all seen The Last of Us right? The hit franchise is based on the real life Cordyceps fungus, but did you know the fungus doesn't take over the brain? The true mechanism behind the zombie fungus is perhaps more terrifying. Also, there is actually a more compelling example of zombie parasites that receives shockingly little attention. In response to listener messages about The Last of Us, Brad puts his Ph.D. studying zombie parasites to work and explains the stories behind Cordyceps, Dicrocoelium and why Toxoplasma might not be all it's cracked up to be.

In our running series on parasites, we’re going to look at another tapeworm–The dwarf tapeworm or Hymenolepis nana. Joining me is parasitology expert, author and friend of the show, Rosemary Drisdelle.

On today’s podcast, we ventured back into the world of trematodes, or flukes and discussed the sheep liver fluke, Fasciola hepatica. Parasitology teacher and author of the book, Parasites: Tales of Humanity’s Most Unwelcome Guests, Rosemary Drisdelle joined me to talk about this parasite.

On today's show we will be talking about a trematode or fluke that is not seen often in humans, but is fascinating just the same Dicrocoelium dendriticum, or the lancet liver fluke. Joining me to lend her expertise in answering questions about this flatworm is Parasitology teacher and author of Parasites: Tales of Humanity's Most Unwelcome Guests, Rosemary Drisdelle.

Angiostrongylosis is a horrible disease affecting dogs not just in the UK but in many other countries besides. The two most commonly reported clinical presentations are associated with spontaneous bleeding or respiratory signs due to verminous pneumonia! In this podcast we discuss this parasitic infection in some depth and I am joined once again by Karen Humm who is a Lecturer in Emergency & Critical Care (ECC) at the QMHA and a co-Director of the Transfusion Medicine service. In the podcast Karen and I were not entirely clear about exactly what the two licensed veterinary preparations are licensed for...I am not sure I am any more clear so here are some links for you to check them out! Milbemax Advocate Alongside this podcast, I have also just published a short blog piece summarising a couple of papers on A. vasorum recently published in The Veterinary Record which you can find HERE. As always, if you have any comments about this podcast, please get in touch (email sjasani@rvc.ac.uk; tweet @RoyalVetCollege using #saclinpod; or use the RVC's Facebook page). Please take 30 seconds (!) to rate the podcasts in iTunes +/- write a review! Thanks. And remember we are now also on Stitcher Radio. PS. In the podcast Karen mentions some parasite that has a life-cycle which as you can tell she finds very exciting! She was keen I shared the link with you so here you go!

In dieser Studie wurde der Parasitenstatus von Kühen aus 25 Betrieben verschiedener Haltungsformen (Laufstall-, Weide- und Mutterkuhhaltung) untersucht. Die Untersuchungen der insgesamt 245 Kühe erfolgte monatlich von Oktober 2002 bis September 2003. MDS waren die am häufigsten nachgewiesenen Parasiten mit einer durchschnittlichen Ausscheidungsextensität zwischen: 1 – 16 % in der Laufstallhaltung, 40 – 70 % in der Weidehaltung und 35 – 64 % in der Mutterkuhhaltung. Die Ausscheidungsintensität lag im Mittel >1EpG in der Laufstallhaltung, zwischen 4,2 und 14 EpG in der Weidehaltung sowie zwischen 2 und 10,3 EpG in der Mutterkuhhaltung. Die Tiere aus Weidehaltung hatten die signifikant höchste Ausscheidungsextensität und –intensität, die Tiere aus der Laufstallhaltung hatten die geringste (P ≤ 0,01). Von Januar bis März war die Ausscheidungsextensität und –intensität am signifikant geringsten, von Juli bis September am höchsten (P ≤ 0,01). Ein Vergleich der Eiausscheidung hinsichtlich des Alters erbrachte keine signifikanten Werte, allerdings hatten die bis Dreijährigen die höchste Ausscheidungsextensität und –intensität. Kokzidien wurden nur in relativ geringen Mengen festgestellt, wobei die Kühe aus der Mutterkuhhaltung die signifikant höchste Ausscheidungsextensität (P ≤ 0,01) hatten. Mit zunehmenden Alter wurde eine abnehmende Ausscheidungshäufigkeit festgestellt. Primipare Tiere hatten signifikant (P ≤ 0,01) höhere Ausscheidungsextensitäten als Multipare. F. hepatica-Befall wurde nur in drei Weide- und zwei Mutterkuhbetrieben nachgewiesen. Die Moniezia Ausscheidungsextensität wie –intensität war gering. Erstaunlicherweise wurde in einem Mutterkuhbetrieb Paramphistomum beobachtet. Dictyocaulus viviparus und Dicrocoelium dendriticum wurden während der Zeit der Untersuchung bei keinem Tier gefunden. Es wurde zu keinem Untersuchungszeitpunkt bei einer der Kühe eine parasitär bedingte klinische Krankheit festgestellt. Aus der vorliegenden Untersuchung geht hervor, dass auch adulte Tiere zu einem hohen Prozentsatz Parasitenträger sind. Die tatsächlichen Befallsextensitäten dürften jedoch noch über den gemessen Werten liegen.
