Cysts of Echinococcus multilocularis Leuck. 1863 were found in 15 of 99 deer mice, Peromyscus maniculatus (Wagner), from a dolomite quarry and a gravel pit 12 and 20 miles north northeast of Winnipeg respectively, in the Stony Mountain – Argyle area. This is the first report on the occurrence of E. multilocularis in Manitoba rodents. It extends northeast the known area of distribution of this cestode in the North American prairies.

Theoretical Risk

AbstractWidespread circulation of SARS-CoV-2 in humans raises the theoretical risk of reverse zoonosis events with wildlife, reintroductions of SARS-CoV-2 into permissive nondomesticated animals. Here we report that North American deer mice (Peromyscus maniculatus) are susceptible to SARS-CoV-2 infection following intranasal exposure to a human isolate, resulting in viral replication in the upper and lower respiratory tract with little or no signs of disease. Further, shed infectious virus is detectable in nasal washes, oropharyngeal and rectal swabs, and viral RNA is detectable in feces and occasionally urine. We further show that deer mice are capable of transmitting SARS-CoV-2 to naïve deer mice through direct contact. The extent to which these observations may translate to wild deer mouse populations remains unclear, and the risk of reverse zoonosis and/or the potential for the establishment of Peromyscus rodents as a North American reservoir for SARS-CoV-2 remains unknown.

Rare Group

The pseudorthoceratid subfamily Macroloxoceratinae Flower, 1957, comprises a rare group of nautiloid cephalopods homeomorphic with the Actinoceratida in the development of a siphonal canal system. With the exception of Macroloxoceras Flower, 1957, from the Upper Devonian of Colorado and New Mexico, this subfamily has previously been reported only from the Mississippian of Europe. A specimen described herein from the late Viséan–?early Namurian Kennetcook Limestone of the Windsor Group of Nova Scotia, assigned to Campyloceras cf. C. unguis (Phillips, 1836), extends the range of the Macroloxoceratinae into the North American Mississippian. This discovery further provides new data on the complex siphonal morphology of this poorly known group of nautiloids, and supplements the recent documentation of the pseudorthoceratids in the Windsor Group cephalopod fauna (Edgecombe, 1987).

North American Genotype

Camellias are important nursery and landscape plants and are known to be highly susceptible hosts of Phytophthora ramorum, the pathogen that causes Sudden Oak Death. This is the first report of camellia flower bud infection in the field with the North American genotype of P. ramorum Accepted for publication 31 May 2006. Published 25 August 2006.
