ABSTRACT The first case of pseudohypoparathyroidism with postmortem examination is reported. Microscopic examination shows hyperplastic upper parathyroid glands (only one was found) and normal age involution in the two found lower glands. All the bones examinated offered signs of exagerated bone replacement in time before death. In the cortical bone of the femur many lacunae of Howship with spare giant cell osteoclasts were seen. Circumscript calcifications in the renal medulla and in the thyroid gland were observed.

Endocarditis associated with Escherichia coli was diagnosed in a 2-year-old male California sea lion ( Zalophus californianus). The diagnosis was based on light microscopic examination and bacterial isolation from the valvular lesion. This is the first case of bacterial endocarditis reported in a sea lion.

AbstractBackgroundThe first case of SARS-CoV-2 in Basel, Switzerland was detected on February 26th 2020. We present a phylogenetic study to explore viral introduction and evolution during the exponential early phase of the local COVID-19 outbreak from February 26th until March 23rd.MethodsWe sequenced SARS-CoV-2 naso-oropharyngeal swabs from positive 746 tests that were performed at the University Hospital Basel in the timeframe of our study. We successfully generated 468 high quality genomes from unique patients and called variants with our COVID-19 Pipeline (COVGAP). We analysed viral genetic diversity using PANGOLIN taxonomic lineages. To identify introduction and dissemination events we incorporated global SARS-CoV-2 genomes and inferred a time-calibrated phylogeny. We used epidemiological data to aid interpretation of phylogenetic patterns.FindingsThe early outbreak in Basel was dominated by lineage B.1 (83·6%), detected from March 2nd, although the first lineage identified was B.1.1. Within B.1, a clade defined by the SNP C15324T contains 68·2% of our samples (‘Basel cluster’), including 157 identical sequences at the root of the ‘Basel cluster’, suggesting local spreading events. We infer the origin of the ‘Basel cluster’ defining mutation to mid-February in our tri-national region. The remaining genomes map broadly over the global phylogenetic tree, evidencing several events of introduction from and/or dissemination to other regions of the world via travellers. We also observe family transmission events.InterpretationA single lineage variant dominated the outbreak in the City of Basel while other lineages such as the first (B1.1) did not propagate. We identify mass gathering events and less so travel returners and family transmission as causes for the local outbreak. We highlight the importance of adding specific questions to the epidemiological questionnaires that are collected, to obtain data on attendance of large gathering events and locations as well as travel history to effectively identify routes of transmissions in up-coming outbreaks. This phylogenetic analysis enriches epidemiological and contact tracing data, allowing, even retrospectively, connection of seemingly unconnected events, and can inform public health interventions.

History Of

Canine distemper and pulmonary sarcocystosis were diagnosed in a 10-week-old Rottweiler with 4-day history of diarrhea, vomiting, and weakness. Microscopic examination of the lung revealed bronchointerstitial pneumonia typical of morbillivirus infection. Also, numerous apicomplexan parasites were scattered in the alveolar walls. This protozoan infection was first thought to be toxoplasmosis but immunoperoxidase staining revealed large numbers of Sarcocystis canis. This is the first case of canine sarcocystosis reported from Latin America that further emphasizes the importance of immunohistochemistry in the differential diagnoses of apicomplexan infections in dogs.

Task Assessment

ABSTRACTThe Wisconsin State Laboratory of Hygiene challenged Wisconsin laboratories to examine their biosafety practices and improve their culture of biosafety. One hundred three clinical and public health laboratories completed a questionnaire-based, microbiology-focused biosafety risk assessment. Greater than 96% of the respondents performed activities related to specimen processing, direct microscopic examination, and rapid nonmolecular testing, while approximately 60% performed culture interpretation. Although they are important to the assessment of risk, data specific to patient occupation, symptoms, and travel history were often unavailable to the laboratory and, therefore, less contributory to a microbiology-focused biosafety risk assessment than information on the specimen source and test requisition. Over 88% of the respondents complied with more than three-quarters of the mitigation control measures listed in the survey. Facility assessment revealed that subsets of laboratories that claim biosafety level 1, 2, or 3 status did not possess all of the biosafety elements considered minimally standard for their respective classifications. Many laboratories reported being able to quickly correct the minor deficiencies identified. Task assessment identified deficiencies that trended higher within the general (not microbiology-specific) laboratory for core activities, such as packaging and shipping, direct microscopic examination, and culture modalities solely involving screens for organism growth. For traditional microbiology departments, opportunities for improvement in the cultivation and management of highly infectious agents, such as acid-fast bacilli and systemic fungi, were revealed. These results derived from a survey of a large cohort of small- and large-scale laboratories suggest the necessity for continued microbiology-based understanding of biosafety practices, vigilance toward biosafety, and enforcement of biosafety practices throughout the laboratory setting.
