Abstract
The aim of this study was to evaluate the potential role of office fomites in respiratory (human parainfluenza virus 1-HPIV1, human parainfluenza virus 3-HPIV3) and enteric (norovirus GI-NoV GI, norovirus GII-NoV GII) viruses transmission by assessing the occurrence of these viruses on surfaces in office buildings. Between 2016 and 2017, a total of 130 surfaces from open-space and non-open-space rooms in office buildings located in one city were evaluated for HPIV1, HPIV3, NoV GI, and NoV GII viral RNA presence. Detection of viruses was performed by RT-qPCR method. Study revealed 27 positive samples, among them 59.3% were HPIV3-positive, 25.9% HPIV1-positive, and 14.8% NoV GII-positive. All tested surfaces were NoV GI-negative. Statistical analysis of obtained data showed that the surfaces of office equipment including computer keyboards and mice, telephones, and desktops were significantly more contaminated with respiratory viruses than the surfaces of building equipment elements such as door handles, light switches, or ventilation tracts (χ 2 p = 0.006; Fisher's Exact p = 0.004). All examined surfaces were significantly more contaminated with HPIVs than NoVs (χ 2 p = 0.002; Fisher's Exact p = 0.003). Office fomites in open-space rooms were more often contaminated with HPIVs than with NoVs (χ 2 p = 0.016; Fisher's Exact p = 0.013). The highest average concentration of HPIVs RNA copies was observed on telephones (1.66 × 102 copies/100 cm2), while NoVs on the light switches (1.40 × 102 copies/100 cm2). However, the Kruskal-Wallis test did not show statistically significant differences in concentration levels of viral RNA copies on surfaces between the all tested samples. This study unequivocally showed that individuals in office environment may have contact with both respiratory and enteric viral particles present on frequently touched surfaces.

Abstract
Human parainfluenza viruses (HPIVs) are a common cause of acute respiratory illness throughout life. Infants, children, and the immunocompromised are the most likely to develop severe disease. HPIV1 and HPIV2 are best known to cause croup while HPIV3 is a common cause of bronchiolitis and pneumonia. HPIVs replicate productively in respiratory epithelial cells and do not spread systemically unless the host is severely immunocompromised. Molecular studies have delineated how HPIVs evade and block cellular innate immune responses to permit efficient replication, local spread, and host-to-host transmission. Studies using ex vivo human airway epithelium have focused on virus tropism, cellular pathology and the epithelial inflammatory response, elucidating how events early in infection shape the adaptive immune response and disease outcome.

Abstract
The lungs are among the most vulnerable to microbial assault of all organs in the body. From a contemporary vantage, lower respiratory tract infections are the greatest cause of infection-related mortality in the United States, and rank seventh among all causes of deaths in the United States.2,3 From a global and historic perspective, the scope and scale of lower respiratory tract infection is greater than any other infectious syndrome, and viral pneumonias have proven to be some of the most lethal and dramatic of human diseases. The 1918–1919 influenza pandemic, perhaps the most devastating infectious disease pandemic in recorded history, resulted in an estimated 40 million deaths worldwide, including 700,000 deaths in the U.S.4 The global outbreak of severe acute respiratory syndrome (SARS) during 2003, although considerably smaller in scale, resulted in 8098 cases and 774 deaths5 and is a dramatic contemporary example of the ability of viral pneumonias to rapidly disseminate and cause severe disease in human populations.

Abstract
Human parainfluenza viruses (HPIV) were first discovered in the late 1950s. Over the last decade, considerable knowledge about their molecular structure and function has been accumulated. This has led to significant changes in both the nomenclature and taxonomic relationships of these viruses. HPIV is genetically and antigenically divided into types 1 to 4. Further major subtypes of HPIV-4 (A and B) and subgroups/genotypes of HPIV-1 and HPIV-3 have been described. HPIV-1 to HPIV-3 are major causes of lower respiratory infections in infants, young children, the immunocompromised, the chronically ill, and the elderly. Each subtype can cause somewhat unique clinical diseases in different hosts. HPIV are enveloped and of medium size (150 to 250 nm), and their RNA genome is in the negative sense. These viruses belong to the Paramyxoviridae family, one of the largest and most rapidly growing groups of viruses causing significant human and veterinary disease. HPIV are closely related to recently discovered megamyxoviruses (Hendra and Nipah viruses) and metapneumovirus.

Abstract
Sequencing studies of limited regions of the human parainfluenza viruses (HPIVs) genomes have helped describe patterns of virus circulation and characterize institutional outbreaks of HPIVs-associated respiratory illness. In this study, we sequenced reverse transcription polymerase chain reaction (RT-PCR)-amplified HPIVs RNA obtained from a multiplex RT-PCR assay described previously for simultaneous detection of HPIV-1, 2 and 3. Differences in the nucleotide sequences of limited regions of the HN gene allowed us to distinguish temporally and geographically diverse HPIV isolates (43 HPIV-1, 7 HPIV-2, 12 HPIV-3 isolates from this and previously published studies). In addition, an outbreak of HPIV-3-associated illness among infants on a pediatric ward was investigated by comparing sequences of three ward isolates with three matched community controls. Sequences of all ward isolates were identical and differed from those of the community controls, suggesting a single introduction and nosocomial transmission of the virus. Combining multiplex reverse transcription polymerase chain reaction (RT-PCR) assays with direct sequencing of the PCR products can provide an integrated system for rapid diagnosis and characterization of HPIVs.

Abstract
Reverse transcription (RT)-PCR assays have been widely described for use in the diagnosis of human parainfluenza viruses (HPIVs) and other respiratory virus pathogens. However, these assays are mostly monospecific, requiring separate amplifications for each HPIV type. In the present work, we describe multiplex RT-PCR assays that detect and differentiate HPIV serotypes 1, 2, and 3 in a combined reaction. Specifically, a mixture of three pairs of primers to conserved regions of the hemagglutinin-neuraminidase gene of each HPIV serotype was used for primary amplification, yielding amplicons with similar sizes. For typing, a second amplification was performed with a mixture of nested primers, yielding amplicons with sizes easily differentiated by agarose gel electrophoresis. A modified single-amplification RT-PCR assay with fluorescence-labeled nested primers, followed by analysis of the labeled products on an automated sequencing gel, was also evaluated. Fifteen temporally and geographically diverse HPIV isolates from the Centers for Disease Control and Prevention archives and 26 of 30 (87%) previously positive nasopharyngeal specimens (8 of 10 positive for HPIV serotype 1 [HPIV1], 9 of 10 positive for HPIV2, and 9 of 10 positive for HPIV3) were positive and were correctly typed by both assays. Negative results were obtained with naso- or oropharyngeal specimens and/or culture isolates of 33 unrelated respiratory tract pathogens, including HPIV4, enterovirus, rhinovirus, respiratory syncytial virus, adenovirus, influenza virus, and Streptococcus pneumoniae. Our multiplex RT-PCR assays provide sensitive, specific, and simplified tools for the rapid diagnosis of HPIV infections.

Abstract
A series of experiments were undertaken to examine how interferon and neutralizing antibodies influence the ability of simian virus 5 (SV5) (strain W3) to establish and maintain persistent infections in murine cells. In contrast to the rapid decline in SV5 protein synthesis observed in murine BALB/c fibroblasts (BF cells), which produce and respond to interferon, between 24 and 48 h postinfection there was no inhibition of virus protein synthesis in MSFI- cells, skin fibroblasts derived from alpha/beta-interferon receptor knockout BALB/c mice. Furthermore, the addition of anti-interferon antibodies to the culture medium of infected BF cells significantly reduced the observed decline in virus protein synthesis. Following infection of untreated BF cells, the majority replicated virus but survived the infection and eventually cleared the virus after 8 to 15 days. However, not all the cells were cured, and the cultures became persistently infected. Upon passage of persistently infected cultures, the virus fluxed between active and repressed states as a consequence of interferon production. This resulted in a balance being reached in which only 5 to 20% of the cells were infected at any one time. After 30 passages of the persistently infected cells, highly fusogenic virus variants arose (one of which was isolated and termed W3-f). W3-f remained as sensitive to interferon as the parental W3 isolate but, in the absence of interferon, spread much more rapidly than the parental W3 strain through BF cell monolayers. Sequence analysis revealed no deduced amino acid differences between the F proteins of W3 and W3-f. BF cell cultures persistently infected with W3-f were rapidly cleared of virus by the addition of virus-neutralizing antibodies to the culture medium. In contrast, neutralizing antibodies had little effect on the numbers of cells persistently infected with W3 over several passages. These results suggest that the ability of paramyxoviruses to cause cell-cell fusion may be selected for in vivo as a consequence of their adaptation to the interferon response rather than their need to escape from neutralizing antibodies. The significance of these observations with regard to persistent parainfluenza virus infections in vivo is further discussed.

Abstract
Pulmonary disease is a common presenting feature and complication of T-cell immunodeficiency. We retrospectively reviewed 15 children with severe combined immune deficiency (SCID) and 19 children with DiGeorge syndrome at the time of their first presentation to the Royal Children's Hospital in the 15-year period from 1981 to 1995. In children with SCID, pulmonary disease was a common (67%) presenting feature and the organisms identified were Pneumocystis carinii (PCP) (n = 7), bacteria (n = 4), viruses (n = 3), and a fungus (n = 1). Late pulmonary complications included lower respiratory tract infections, bronchiolitis obliterans, and lymphointerstitial pneumonitis. Pulmonary infections were common (17 occasions) and the organisms identified were bacteria (n = 7), viruses (n = 6), fungi (n = 3), and Mycobacterium tuberculosis (n = 1). Pulmonary complications were responsible for 5 of 9 deaths. PCP was not identified as a late complication in any child, presumably as a result of effective prophylactic therapy. Although pulmonary disease was not a major presenting feature in children with DiGeorge syndrome, pulmonary complications were common. These included recurrent bacterial and viral infections and bronchomalacia, which complicated management and predisposed to morbidity and mortality, even in those without a T-cell defect. We conclude that pulmonary disease is a common manifestation in children with SCID and DiGeorge syndrome.

Abstract
Children, 36, predisposed to frequent upper respiratory infections were treated with endonasal administration of an IgA enriched preparation or placebo in a randomized double blind trial. We found a reduction in the number of infectious episodes and in the number of enlarged regional lymph nodes. Also, an increase of IgA levels in saliva in the treated group was observed, probably not only due to the effect of IgA supplementation, but also to an immunoregulatory effect on the mucosa caused by the preparation administered. We found this therapy very useful in the prophylaxis of upper respiratory infections, being the nasal administration very convenient to be used in children.

Abstract
An autopsy case of measles giant cell pneumonia with intranuclear inclusion bodies is reported. This case of giant cell pneumonia was studied by light microscopy and immunohistochemistry using monoclonal and polyclonal antibody to measles and by electron microscopy (EM). Light microscopic examination showed multinucleated epithelial giant cells with intranuclear and intracytoplasmic inclusions. The giant cells contained prominent, sharply marginated, eosinophilic intranuclear inclusions typical of classic measles pneumonia. Presence of measles antigen was confirmed using both monoclonal and polyclonal antibodies by peroxidase antiperoxidase method. Monoclonal antibody stained positively for intracytoplasmic and intranuclear inclusions. Electron microscopic examination of lung tissue showed intranuclear inclusions of filamentous or worm like nucleocapsid materials in multinucleated epithelial giant cells. The results suggest that this is a case of measles giant cell pneumonia and the intranuclear inclusion bodies are measles viral particles.

Abstract
Parainfluenza virus type 3 (PIV-3), an important lower respiratory tract pathogen in young children and immunocompromised individuals, may be underdiagnosed because of the insensitivity of available culturing systems and delay in identification of virus in cell culture. We developed a reverse transcription-PCR-enzyme immunoassay (RT-PCR-EIA) for PIV-3, using primers specific for a highly conserved region of the hemagglutinin-neuraminidase gene. Testing of nasal washes spiked with PIV-3 or other respiratory viruses showed that this assay detected seven strains of PIV-3 but not other respiratory viruses. Of 103 respiratory tract samples obtained from children experimentally infected with a liver PIV-3 vaccine or naturally infected with wild-type PIV-3, 51 were positive by culture and 48 were positive by RT-PCR-EIA. Eleven of the culture-positive samples were negative by RT-PCR-EIA; however, none of these grew virus upon reinoculation into cell culture, indicating that virus was lost or was present at a very low titer. Eight of the culture-negative samples were positive by RT-PCR-EIA: two were obtained from a subject who was culture negative but had a serologic response to PIV-3, four were obtained 7 to 9 days after the first positive culture, and two were obtained 1 day prior to the first positive culture. Thus, this RT-PCR-EIA for PIV-3 is sensitive and specific and can detect viral RNA in samples from which virus cannot be cultivated. This assay could be used for diagnosis late in the course of PIV-3 infection and for accurate detection of disease outbreaks.

Abstract
When purified dimers of hemagglutinin-neuraminidase molecules released by protease digestion from three strains of human parainfluenza virus 1 were used in crystallization trials, long thin needle crystals formed. Electron microscopic analysis of these needle crystals revealed that they are composed of stacks of triple-stranded helices with each strand of the helix made up of subunits of hemagglutinin-neuraminidase. To our knowledge, this is the first direct demonstration of the assembly of protein subunits into large triple-stranded helices. An understanding of the organization of these triple helices may shed light on the structural properties of the hemagglutinin-neuraminidase molecules that cause them to form these helices.

Abstract
As a result of the enlarging pool of unvaccinated children and young adults, there has been an increase in serious measles pneumonitis in our areas. We recently examined autopsy and/or lung biopsy material from five children with fatal measles pneumonitis. Two patients were immunocompromised because of either prematurity or acute leukemia and died 13-16 days following onset of symptoms. Both had classic giant cell pneumonitis, with readily demonstrable intranuclear inclusions. Three other children without known immunocompromise had a more prolonged course. The lungs of these patients lacked the classic pattern and displayed instead a spectrum of less specific findings ranging from organizing diffuse alveolar damage to interstitial pneumonia with giant cells, but without viral inclusions. An accompanying necrotizing bronchiolitis was also present. Electron microscopy and/or detection of elevated measles-specific immunoglobulin M was necessary to confirm the diagnosis in these apparently immunocompetent patients. We conclude that the histologic features of fatal or serious measles pneumonitis are variable and depend to some extent on the immunocompetence of the host as well as the duration and tempo of the disease. Ancillary studies may be necessary to establish the diagnosis in cases lacking classic histopathologic features.

Abstract
Human parainfluenza virus 3 replicates well in the noses and lungs of two species of cotton rats, Sigmodon hispidus and Sigmodon fulviventer. Peak viral titers of nearly 10(6) PFU/g are reached 2 days after infection in both tissues, are maintained through day 5, and are equivalent in the two species. Infectious virus is eliminated by day 8 after infection. Both species produce a strong neutralizing antibody response with titers of 1:10,000 4 weeks after infection. Viral replication in the nasal epithelium results in only minor histological changes, and viral antigen is found only in the apical portion of epithelial cells. Infection of S. hispidus causes a bronchiolitis with a peribronchiolar lymphoid cell infiltration that reaches a peak 6 days after infection, and there is only a minor component of interstitial pneumonia. In contrast, infection of S. fulviventer causes an interstitial pneumonia, and this lesion reaches its maximal extent by 6 days after infection. There is minimal peribronchiolar lymphoid cell infiltration in infected S. fulviventer. Lung lesions in both species of cotton rats are largely healed 9 days after infection, and the lungs are indistinguishable from those of uninfected controls 16 days after infection. These species of cotton rats offer separate models for the two major pulmonary manifestations of human parainfluenza virus 3 infection. The models may be useful for basic studies of the pathogenesis of this infection and for initial evaluation of candidate vaccines.

Abstract
Three dilutions of each of three parainfluenza strains were placed on nonabsorptive (stainless steel, laminated plastic, skin) and absorptive (hospital gown, facial tissue, laboratory coat) surfaces to assess persistence of virus recovery at 0, 0.5, 1, 2, 4, 6, 8, and 10 hours. Virus persisted longest on stainless steel. Additionally, the ability to recover virus was enhanced by increasing the initial concentration of virus in the initial inoculum. Drying of the inoculum on surfaces reduced but did not immediately eliminate the ability to recover virus. Cleaning the contaminated surface with a number of commonly available disinfectant or antiseptic agents reduced or eliminated virus with only short exposure times. It is likely that removal of contaminated material by vigorous cleaning was as important as the actual disinfecting substance. In general, all three strains of parainfluenza virus responded similarly. Persistence of all three strains of parainfluenza virus for up to 10 hours on nonabsorptive surfaces and up to 4 hours on absorptive surfaces suggests a need to consider fomites a possible source of transmission of the parainfluenza viruses inside and outside the hospital.

Abstract
We report a 21-day-old preterm infant who had severe respiratory distress of 6 days' duration and whose lungs revealed a giant cell pneumonia at necropsy. Measles antigen was demonstrated in mononuclear and multinucleated epithelial cells of the lung by immunoperoxidase staining. We recommend the immunostaining procedure to differentiate measles from other viruses, such as parainfluenza 2 or 3, and respiratory syncytial virus, all of which may produce giant cell pneumonias.

Abstract
The localization of measles virus proteins was analyzed by immunoperoxidase method using both monospecific and monoclonal antibodies. In Vero cells infected with the Edmonston or EB-L strain, the former being a laboratory strain and the latter a fresh isolate from a measles patient, nucleocapsid protein was located in the nuclei, and matrix protein, phosphoprotein, haemagglutinin and fusion protein were located in the cytoplasm. In the lung tissues of eight cases with measles giant cell pneumonia, the similar findings were obtained. The presence of haemagglutinin on the surface of giant cells at the luminal side was also noticed. Histopathologically, measles giant cells had nuclear and cytoplasmic eosinophilic inclusion bodies with some differences in appearance. The significance of localization of viral proteins is discussed in comparison with histopathological findings in measles giant cells.

Abstract
The primary manifestation of the immunodeficiencies is undue susceptibility to infection. This means too many, too severe, too prolonged, too complicated and too unusual infections. Infections in immunodeficiency have a characteristic cause depending on the nature of the immune deficiency. Antibody deficiencies are associated with infections with gram-positive infections. Cellular immune deficiencies are associated with mycobacterial, protozoan, fungus, virus, and opportunistic bacterial infection. Phagocytic disorders are associated with staphylococcal, fungal, and gram-negative organisms. Complement disorders are associated by neisserial infections. Infections have also been implicated in the pathogenesis of some immunodeficiencies in some circumstances. These include human T lymphotropic virus type III (HTLV-III), rubella virus, cytomegalovirus, and Epstein-Barr virus. Several infectious syndromes in specific immunodeficiencies have been identified. Examples include enteric cytopathic human orphan (ECHO) virus encephalitis in agammaglobulinemia, and meningococcal meningitis in C6 deficiency. Infections can also be induced by live vaccines given in immunodeficiency (e.g., paralytic polio in agammaglobulinemia.) Unusual infectious syndromes will be illustrated including parainfluenza infection in severe combined and immunodeficiency, Legionella pneumonia in chronic granulomatous disease, and Cryptosporidium infection in hyper-IgM immunodeficiency.

Abstract
The survival of human parainfluenza virus types 1, 2, and 3 was measured in both indoor and outdoor environments at South Pole Station, Antarctica, in an effort to determine the long-term survival of these viruses in this environment and to identify the possible source of respiratory tract illnesses which occurred in this isolated population in 1978 after 10 and 27 weeks of total social isolation. Viruses were applied to plastic petri plate surfaces which were then stored in indoor (21.4 degrees C; water vapor density, 1.50 g of water per m3) and outdoor environments (-22.4 to -33.2 degrees C; water vapor density, 0.706 and 0.247 g of water per m3). Parainfluenza virus type 1 at an initial titer of 3.75 log10 50% tissue culture infective doses per ml was inactivated after 4 days at room temperature and after 7 days outside. Parainfluenza virus type 2 and 3 at initial titers of 5.58 and 5.38 log10 50% tissue culture infective doses per ml were inactivated after 7 and 12 days, respectively, at room temperature and after 17 days of storage outside. Results indicate that the long-term survival of parainfluenza virus in either environment for up to 10 weeks is unlikely and probably did not provide the source of infectious virus responsible for the midisolation outbreaks of parainfluenza virus-related respiratory tract illnesses observed in this population during the 1978 winter season.

Abstract
In order to determine the natural history of parainfluenza virus infection in early life, we followed prospectively 130 infants and children from birth or a few months of age for evidence of infection with PV. Using rapid diagnostic techniques, standard tissue culture infectivity, and serologic techniques we were able to document primary PV infection in 92% of these infants, and repeated infection with heterotypic or homotypic PV strains in 49% by 30 months of age. Increasing patient age had no significant effect in reducing the incidence of lower respiratory tract illness as a result of PV infection. Infection with one PV serotype provided no protection against LRTI at the time of subsequent infection with a heterotypic PV strain. In contrast, primary PV infection provided a brief period of immunity to LRTI upon homotypic reinfection. Secretory IgA responses to PV were determined by immunofluorescent techniques. Antibody response to PV strains causing primary infection and heterotypic repeated infection were transient and of low magnitude. Homotypic reinfection resulted in significantly enhanced production of secretory antibody to PV. At least in early life, repeated exposures to PV appear to be essential for maintaining immunity to severe forms of illness caused by PV infection.

Abstract
Giant cell pneumonia associated with parainfluenza virus type 3 infection and chronic poliovirus type 2 meningoencephalomyelitis are documented in an infant with combined immunologic deficiency (Swiss type). Caution should be exercised in attributing cases of giant cell pneumonia to measles virus without serologic or virologic evidence.

Abstract
A patient with DiGeorge syndrome developed pneumonia caused by para-influenza virus type 3 two years after immunological reconstitution with foetal thymic eptihelium. There was a transient reduction of mitogen-induced lymphocyte transformation at the time of the pneumonia. Although she recovered from the pneumonia, brochitis persisted and the virus could still be isolated from her pharyngeal secretions 3 1/2 months later.

Abstract
The effects of monospecific antibodies to the viral glycoprotein with hemagglutinating and neuraminidase activity (HN) and the viral glycoprotein with membrane-fusing activity (F) of the paramyxovirus simian virus 5 (SV5) on the spread of infection in two cell types have been investigated. In CV-1 cells, infection can spread by either released progeny virus adsorbing to and infecting other cells, or by fusion of an infected cell with an adjacent cell as a result of the cell-fusing activity of the F glycoprotein. In these cells, antibodies specific for the HN glycoprotein prevented the dissemination of infection by released infectious virus, but spread by cell fusion was not inhibited. Antibodies to the F glycoprotein completely prevented the spread of infection in these cells. In Madin-Darby bovine kidney cells, which are relatively resistant to SV5-induced fusion, antibodies to either the HN or F glycoproteins were capable of preventing the dissemination of infection. These results indicate that effective immunological prevention of the spread of paramyxovirus infection requires the presence of antibodies that inactivate the F glycoprotein. This requirement for anti-F antibodies has obvious implications for the design of effective paramyxovirus vaccines and provides an explanation for previous failures of formalin-inactivated paramyxovirus vaccines as well as additional insight into the possible immunopathological mechanisms involved in the atypical and severe infections that have occurred in individuals who received inactivated paramyxovirus vaccines and were subsequently infected by the virus.
