Human Parainfluenza Virus

The most comprehensive phylogenetic classification of human parainfluenza virus 3 (HPIV-3) was recently developed [PLoS One 2012;7:e43893]. This classification included three distinct clusters (A, B and C) with subdivision of cluster C into four subclusters (C1-4). In the present report, the classification of HPIV-3 was refined by inclusion of 27 overlooked beside newly characterized Saudi variants. The new phylogram was developed and included the same clusters described before, in which cluster A remained unchanged and cluster B contained more recent isolates. The organization of cluster C was altered through inclusion of a new subcluster (C5), subdivision of C1 into two lineages C1a and C1b and subdivision of C3 into three lineages C3a, C3b and C3c. The majority of Saudi variants were classified as members of subcluster C1b, whereas only one variant was placed in each of subclusters C2 and C5. This study illustrates an up-to-date phylogenetic classification of HPIV-3 variants.

AbstractA dual molecular and cytogenetic study was performed with the aim to improve the controversial systematic classification of some species of Lamiinae (Coleoptera: Cerambycidae). The karyotypes of species belonging to genera Morimus, Herophila, Dorcadion, Neodorcadion and Lamia share a number of characters, which differentiate them from other species, belonging to genera Phytoecia, Parmena and Monochamus. The karyotypes of the last three species comprise 20 chromosomes, mostly metacentric or sub-metacentric, as in the presumed Cerambycidae ancestors. The karyotypes of the former species share many characters derived from the Lamiinae ancestors by a number of chromosome fissions and inversions indicating their monophyly. Comparisons of the CO1 gene sequence also show the monophyly of Morimus, Lamia, Herophila and Dorcadion and their distant relationship with others. These convergent results allow us to propose a phylogenetic classification of these genera, which places the monospecific genus Lamia close to Dorcadion, clearly separates Dorcadion and Neodorcadion and places Herophila closer to Morimus than to Dorcadion/Lamia. The genus Morimus is the most derived. CO1 mutations loosely separate the forms M. asper and M. funereus, which have similar karyotypes and behaviour and copulate in captivity. The form M. ganglebaueri may have a funereus X asper hybrid origin.

Human Parainfluenza Virus

Unusual, severe infections or inflammatory episodes in newborns and infants are largely unexplained and often attributed to immature immune responses. Inborn errors of immunity (IEI) are increasingly recognized as the etiology of life-threatening inflammatory and infectious diseases in infancy. We describe a patient with a unique neonatal-onset Familial Mediterranean Fever (FMF) due to compound heterozygous variants in <i>MEFV</i>, presenting as pleuritis following human parainfluenza virus-4 infection. Diagnostic challenges of FMF in infancy include the interpretation of the attacks as infectious episodes. Newborns and infants with acute, recurrent, or chronic, unusually severe infectious or inflammatory conditions should be screened for IEI, including both disorders with defective immunological responses and autoinflammatory disorders.
