ABSTRACT.
Apple, pear and peach orchards are usually planted in close proximity, and they might share pathogenic fungal species affecting different plant organs. In particular, species of Botryosphaeriaceae have been indicated as responsible for wood diseases in these fruit species. Symptoms frequently observed in Uruguay include papyraceous cankers in apple trunks, dead shoots in pears, and gummosis in peach shoots and branches. Symptomatic tissues of these species were sampled, and fungi resembling species within Botryosphaeriaceae were isolated and identified based on phylogenetic analysis of the internal transcribed spacer region (ITS), part of the translation elongation factor 1-α gene (EF1-α) and part of the RNA polymerase II subunit gen (RPB2). Pathogenicity of selected isolates was assessed under laboratory and field onditions. Botryosphaeria dothidea, Diplodia seriata and Neofusicoccum parvum were isolated from the three hosts from symptomatic tissues. However, only N. parvum proved to be pathogenic when inoculated on trees of all three species, while D. seriata showed pathogenicity towards apple and peach trees only. Diplodia mutila and N. australe were isolated less frequently and not from all the host species. However, they were the most virulent based on lesion length on all tested plant species. The fact that fungal isolates obtained from one host could cause disease symptoms also in some of the alternative hosts suggests that cross infections are possible between apple, pear and peach trees. Finally, Diplodia pseudoseriata in Prunus persica and Diplodia mutila in Pyrus communis, are new records for these hosts in Uruguay.

Abstract:Acute leptospirosis is an infrequent disease in sheep that can cause jaundice, haemolysis, haemoglobinuria, hepatitis and nephritis. In most reports the diagnoses have been made by clinical, pathological or serological evidence without isolation or direct identi?cation of the agent. Here, we report one con?rmed and one presumptive outbreak of acute leptospirosis in suckling lambs from two unrelated sheep farms in Uruguay with mortalities of 9/60 (15%) and 9/163 (5.5%) lambs. Both outbreaks occurred in Sep?Oct 2017 after heavy rainfall and ?ooding events. The main gross and histologic pathological ?ndings in two autopsied lambs, one from each farm, included severe di?use jaundice, haemoglobinuria, acute necrotizing hepatitis with cholestasis and interstitial nephritis. Leptospira interrogans serogroup Pomona serovar Kennewicki was isolated from sheep in both ?ocks and the same genotype was identi?ed directly in clinical samples from infected animals, including one of the deceased lambs subjected to autopsy, by ampli?cation and partial sequencing of rrs and secY genes. This serovar has recently been identi?ed in infected cattle and humans in Uruguay . The impact of Leptospira spp. infection in ovine health, and the epidemiologic role of sheep as reservoirs of leptospirosis for humans and animals need further investigation. © 2019 Blackwell Verlag GmbH |
