Q fever is a common zoonosis worldwide. Awareness of the disease and newer diagnostic modalities have resulted in increasing recognition of unusual manifestations. We report 3 cases of Q fever osteomyelitis in children and review the literature on 11 other reported cases. The cases demonstrate that Coxiella burnetii can cause granulomatous osteomyelitis that presents without systemic symptoms and frequently results in a chronic, relapsing, multifocal clinical course. Optimal selection and duration of antimicrobial therapy and methods of monitoring therapy are currently uncertain.

There is a significant clinical need to identify novel ligands with high selectivity and potency for GABA(A), GABA(C) and glycine receptor Cl- channels. Two recently developed, yellow fluorescent protein variants (YFP-I152L and YFP-V163S) are highly sensitive to quench by small anions and are thus suited to reporting anionic influx into cells. The aim of this study was to establish the optimal conditions for using these constructs for high-throughput screening of GABA(A), GABA(C) and glycine receptors transiently expressed in HEK293 cells. We found that a 70% fluorescence reduction was achieved by quenching YFP-I152L with a 10 s influx of I- ions, driven by an extemal I- concentration of at least 50 mM. The fluorescence quench was rapid, with a mean time constant of 3 s. These responses were similar for all anion receptor types studied. We also show the assay is sufficiently sensitive to measure agonist and antagonist concentration-responses using either imaging- or photomultiplier-based detection systems. The robustness, sensitivity and low cost of this assay render it suited for high-throughput screening of transiently expressed anionic ligand-gated channels. (c) 2005 Elsevier Ireland Ltd.

A captive yellow-tailed black cockatoo (Calyptorhynchus funereus) and 2 free-living tawny frogmouths (Podargus strigoides), both native Australian species, were presented with neurologic signs including depression and pelvic limb paresis and paralysis. Despite supportive treatment, all 3 birds died or were euthanatized. On histologic examination, sections of metastrongyloid nematode larvae were found in the central nervous system of all 3 birds, whereas intact larvae, identified as Angiostrongylus cantonensis, were recovered from the brain and spinal cord of 2 birds. Angiostrongylus cantonensis, the rat lungworm. has an obligatory migratory phase through the host's central nervous system, which can cause severe pathologic lesions. Natural infections in accidental hosts have been documented only in mammals, and to our knowledge, angiostrongyliasis in avian hosts has not been previously reported.
