Most plant pathogens exhibit host specificity but when former barriers to infection break down, new diseases can rapidly emerge. For a number of fungal diseases, there is increasing evidence that hybridization plays a major role in driving host jumps. However, the relative contributions of existing variation versus new mutations in adapting to new host(s) is unclear. Here we reconstruct the evolutionary history of two recently emerged populations of the fungus Pyricularia oryzae that are responsible for two new plant diseases: wheat blast and grey leaf spot of ryegrasses. We provide evidence that wheat blast/grey leaf spot evolved through two distinct mating episodes: the first occurred ~60 years ago, when a fungal individual adapted to Eleusine mated with another individual from Urochloa. Then, about 10 years later, a single progeny from this cross underwent a series of matings with a small number of individuals from three additional host-specialized populations. These matings introduced non-functional alleles of two key host-specificity factors, whose recombination in a multi-hybrid swarm probably facilitated the host jump. We show that very few mutations have arisen since the founding event and a majority are private to individual isolates. Thus, adaptation to the wheat or Lolium hosts appears to have been instantaneous, and driven entirely by selection on repartitioned standing variation, with no obvious role for newly formed mutations. © 2023, The Author(s). |

Resumen: Campylobacter fetus fetus (Cff) es una importante causa de abortos en ovinos y un patógeno oportunista en humanos. La información sobre Cff como abortifaciente en ovinos en Sudamérica es limitada. Describimos un caso de aborto causado por una cepa de Cff multirresistente a antibióticos en una oveja en Uruguay. En agosto de 2017, 3/57 ovejas prenadas ?(5,3%) abortaron en una semana. El examen histopatológico de la placenta de una de ellas reveló placentitis neutrofílica fibrinonecrosante severa, vasculitis y trombosis. Cff fue aislado en microaerobiosis en agar Skirrow, y confirmado mediante amplificación del ADNr 16S por PCR seguida de secuenciación, y por PCR punto final y qPCR. Las pruebas de sensibilidad antimicrobiana revelaron resistencia a tetraciclinas, ácido nalidíxico, telitromicina y clindamicina. No se detectaron otros abortifacientes.

Abstract Campylobacter fetus fetus (Cff) is a major infectious cause of abortion in sheep worldwide, and an opportunistic human pathogen. Information on Cff as an ovine abortifacientin South America is limited. We describe a case of abortion caused by a multidrug resistant
strain of Cff in a sheep in Uruguay. In August 2017, 3/57 pregnant ewes (5.3%) aborted whithin one week. Histopathologic examination of the placenta of an aborted ewe revealed severe neutrophilic and fibrinonecrotizing placentitis with vasculitis and thrombosis of the chorionic
arterioles. Cff was isolated on microaerobic culture in Skirrow agar, and further confirmed by 16S rDNA PCR amplification and sequencing, and endpoint and real time PCR assays. Antimicrobial sensitivity testing revealed resistance to tetracyclines, nalidixic acid, telithromycin and
clindamycin. Other abortifacients were not detected. Further studies are necessary to determine the geographic distribution, ecology, epidemiology, economic impact, and antimicrobial resistance of Cff in sheep flocks in Uruguay.
