Publication date: Available online 27 February 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Ellie L. Milnes, Grace Thornton, Alexandre N. Léveillé, Pauline Delnatte, John R. Barta, Dale A. Smith, Nicole NemethAbstractCervid babesiosis, caused by the protozoan hemoparasite Babesia odocoilei and transmitted by the blacklegged tick Ixodes scapularis, is an emerging disease of Canadian cervids. This pathogen has not yet been described in humans. Data are lacking on the role of migratory birds in the adventitious spread of Ba. odocoilei-infected ticks, as well as on the infection status of I. scapularis in environments used by susceptible wildlife hosts. Following a high-mortality outbreak of cervid babesiosis at the Toronto Zoo [TZ], the present study was initiated to investigate Ba. odocoilei and other tick-borne pathogens of veterinary and public health importance (Borrelia burgdorferi sensu stricto (s.s.), Anaplasma phagocytophilum, Borrelia miyamotoi, and Babesia microti) in I. scapularis at three sites in southern Ontario, Canada. Blanket dragging for questing ticks yielded I. scapularis from the three sites evaluated: TZ, Point Pelee National Park, and LPBO. Babesia odocoilei was identified in I. scapularis collected by dragging at the TZ and at Long Point Bird Observatory [LPBO]. Borrelia burgdorferi s.s. was identified in I. scapularis at all three sites. Anaplasma phagocytophilum was identified in I. scapularis collected from the TZ. During the sprin...

Saldaña, M. LaurentiAbstractCutaneous leishmaniasis (CL) is one of the most frequent parasitic zoonoses in Panama. Currently, conventional, molecular and histopathological tests are performed to diagnose CL. Immunohistochemistry (IHC) has proven to be a valuable tool to facilitate the diagnosis of leishmaniasis and to study the cellular immune response developed during the infection. Therefore, considering the absenc...

On the basis of blast analysis of the 18S rRNA gene sequences, our results revealed that seven dogs (5.4%) were infected w...

CONCLUSION: ICOAP-hand is a reliable pain index that correlates with other available pain questionnaires. However, our results indicate that constant and intermittent pain do not represent separate constructs in hand OA, questioning the usefulness of the 2 subscales. [ClinicalTrials.gov: NCT03083548].

Authors: Lefebvre G, Calder LA, De Gorter R, Bowman CL, Bell D, Bow M, National Panel on Quality Improvement in Obstetrics Abstract This paper describes the recommendations of a national panel on quality improvement in obstetrics to identify priorities for action among five areas of greatest medico-legal risk. Using previously conducted medico-legal data analyses and a systematic literature review, the panel reviewed existing data and developed recommendations for areas of focus in quality improvement in five obstetrical high-risk areas. The panel recommended clarification of definitions in some areas, identified n...

Fourteen focus groups and three individual interviews were conducted in five Canadian cities with gay/bisexual men (5 groups; 40 participants), lesbian/bisexual women (5 groups; 29 participants), and transgender persons (3 interviews, 4 groups; 24 part...

Publication date: Available online 15 March 2019Source: Current Opinion in Food ScienceAuthor(s): M Garvey, N.J RowanThe incidence of foodborne illness is increasing globally in an age where antibiotic resistance has become the mainstay for many pathogenic species with potentially fatal consequences for the consumer. Fresh food, including industrial-fabricated ready-to-eat produce, is frequently reported as a leading source of foodborne outbreaks. There is a pressing need to develop alternative or complementary non-thermal technologies for food-surface disinfection given that existing approaches are frequently ineffective ...

Magnetic resonance imaging (MRI) of the brain allows for the identification of structural lesions typical of Alzheimer's disease (AD), the main cause of dementia. However, to have a clinical impact, it is imperative that acquisition and reporting of this MRI-based evidence be standardized, ensuring the highest possible reliability and reproducibility. Our objective was to validate a systematic radiological MRI acquisition and review process in the context of AD.

The objective of the present study was to identify mutations in the GABA-Cl gene associated with fipronil resistance. Genomic DNA was obtained from engorged females from fipronil-susceptible and resistant populations sampled from Uruguay and Brazil (n = 166). Initially, it was searched the T290 L mutation described in Australia; however, this mutation was not detected in individuals from resistant populations from either country. The sequencing of a fragment of the GABA-Cl gene revealed nucleotide polymorphisms in fipronil- and lindane-resistant ticks in two populations from Uruguay and five from Brazi...
