Abstract
Hospitalized children < 2 years of age in Amman, Jordan, admitted for fever and/or respiratory symptoms, were tested for Middle East respiratory syndrome coronavirus (MERS‐CoV): MERS‐CoV by real‐time RT‐PCR (rRT‐PCR). This was a prospective year‐round viral surveillance study in children <2 years of age admitted with acute respiratory symptoms and/or fever from March 2010 to September 2012 and enrolled from a government‐run hospital, Al‐Bashir in Amman, Jordan. Clinical and demographic data, including antibiotic use, were collected. Combined nasal/throat swabs were collected, aliquoted, and frozen at −80°C. Specimen aliquots were shipped to Vanderbilt University and the Centers for Disease Control and Prevention (CDC), and tested by rRT‐PCR for MERS‐CoV. Of the 2433 subjects enrolled from 16 March 2010 to 10 September 2012, 2427 subjects had viral testing and clinical data. Of 1898 specimens prospectively tested for other viruses between 16 March 2010 and 18 March 2012, 474 samples did not have other common respiratory viruses detected. These samples were tested at CDC for MERS‐CoV and all were negative by rRT‐PCR for MERS‐CoV. Of the remaining 531 samples, collected from 19 March 2012 to 10 September 2012 and tested at Vanderbilt, none were positive for MERS‐CoV. Our negative findings from a large sample of young Jordanian children hospitalized with fever and/or respiratory symptoms suggest that MERS‐CoV was not widely circulating in Amman, Jordan, during the 30‐month period of prospective, active surveillance occurring before and after the first documented MERS‐CoV outbreak in the Middle East region.

Abstract
The incidence and type distribution of enteric human adenoviruses (HAds) among diarrheic children in south-western Hungary was investigated from 2003 through 2006. Laboratory studies were conducted using commercial antigen detection tests (latex agglutination or immunochromatography), polymerase chain reaction (PCR) amplification, single-strand conformation polymorphism, and sequencing and phylogenetic analysis of a conservative region of the HAd hexon gene. The overall rate of HAd infection in childhood gastroenteritis cases during the 4-year study was 8.1%, with a gradual decrease in detection rates from 11.7% in 2003 to 5.7% in 2006. Molecular studies of a subset of HAd-positive samples found that enteric HAd type 40 strains were identified only in 2003 and 2004, while HAd type 41 strains were identified throughout the 4-year study. Higher detection rates of non-enteric HAds was documented during the first half of the study period when latex agglutination was used in our laboratory for detection. Our study suggests that the choice of diagnostic method may profoundly influence the epidemiologic picture and disease burden attributed to enteric HAd infections.

Abstract
Community-acquired respiratory virus (RV) infections are an important cause of disease in immunocompromised adults with cancer. To investigate the viral etiology, incidence, clinical presentation, and outcome of RV infections in an outpatient cohort of adult bone marrow or peripheral blood stem cell transplant (SCT) recipients, we monitored 62 outpatient volunteers from January 1 to April 30, 2001. A nasopharyngeal aspirate was collected from subjects when they reported new respiratory symptoms and tested for RV (influenza A, influenza B, human parainfluenza 1-3, adenovirus, and respiratory syncytial virus) by culture and reverse transcription polymerase chain reaction (RT-PCR) assay. Of 62 subjects enrolled, 27% had received allogeneic SCT and 45% were within 1 year of their transplant. In all, 35 participants (56%) reported 37 episodes of respiratory symptoms. Of the 37 specimens tested, five (14%) were positive for RV by culture and 20 (54%) were positive by RT-PCR. Only six patients with RV infections developed lower respiratory tract illnesses; these patients had received either autologous or allogeneic transplants and developed illnesses between 41 and 2666 days post transplant. Although RV infections were common in SCT outpatients during the RV season, most participants had upper respiratory tract infections, which resolved without the need for hospitalization.

Abstract
The common species C adenoviruses (serotypes Ad1, Ad2, Ad5, and Ad6) infect more than 80% of the human population early in life. Following primary infection, the virus can establish an asymptomatic persistent infection in which infectious virions are shed in feces for several years. The probable source of persistent virus is mucosa-associated lymphoid tissue, although the molecular details of persistence or latency of adenovirus are currently unknown. In this study, a sensitive real-time PCR assay was developed to quantitate species C adenovirus DNA in human tissues removed for routine tonsillectomy or adenoidectomy. Using this assay, species C DNA was detected in Ficoll-purified lymphocytes from 33 of 42 tissue specimens tested (79%). The levels varied from fewer than 10 to greater than 2 x 10(6) copies of the adenovirus genome/10(7) cells, depending on the donor. DNA from serotypes Ad1, Ad2, and Ad5 was detected, while the rarer serotype Ad6 was not. When analyzed as a function of donor age, the highest levels of adenovirus genomes were found among the youngest donors. Antibody-coated magnetic beads were used to purify lymphocytes into subpopulations and determine whether viral DNA could be enriched within any purified subpopulations. Separation of T cells (CD4/8- expressing and/or CD3-expressing cells) enriched viral DNA in each of nine donors tested. In contrast, B-cell purification (CD19-expressing cells) invariably depleted or eliminated viral DNA. Despite the frequent finding of significant quantities of adenovirus DNA in tonsil and adenoid tissues, infectious virus was rarely present, as measured by coculture with permissive cells. These findings suggest that human mucosal T lymphocytes may harbor species C adenoviruses in a quiescent, perhaps latent form.

Abstract
OBJECTIVES To study prospectively HIV-positive patients admitted to the hospital because of pneumonia by extensive laboratory tests to determine specific microbiologic diagnoses and to establish the best clinical diagnosis after review of all available data by expert clinicians. METHODS Patients admitted to one of two hospitals had extensive questionnaires completed and defined diagnostic tests performed on blood, sputum, urine and bronchoalveolar lavage specimens, when available. RESULTS A total of 230 patients had a diagnosis of pneumonia verified. A definite or probable etiologic diagnosis was made in 155 (67%) of these patients. Pneumocystis carinii caused 35% of all cases of pneumonia. Twenty-seven percent of cases of pneumonia with a single etiology had a definite or probable bacterial etiology. 'Atypical agents' were distinctly uncommon. Few clinical or laboratory parameters could differentiate specific etiologies. CONCLUSIONS P. carinii continues to be a common cause of pneumonia in these patients. The rarity of 'atypical agents' could simplify the empiric approach to therapy. Despite the use of extensive testing we did not find a definite etiology in a large number of cases.

Abstract
Prefabrication of a latissimus dorsi myocutaneous flap was performed in adult male Landrace pigs. Gelfoam sponges were used as a delivery system for basic fibroblast growth factor (bFGF) at the muscle-subcutaneous tissue interface. Skin survival and angiogenesis were augmented in the growth-factor-treated animals. These data support the use of basic fibroblast growth factor to enhance flap prefabrication.

Abstract
OBJECTIVES To determine the causes of an outbreak of lobar pneumonia. DESIGN Matched (1:2) case-control study. SETTING A 70-bed chronic care facility for older people. PARTICIPANTS Residents of the facility. RESULTS Ten residents developed pneumonia over a 10-day period. Two residents died. One case-patient had Streptococcus pneumoniae bacteremia; another had polymerase chain reaction evidence of S. pneumoniae infection. No other etiologic agent was identified. Only four of 10 case-patients had received routine diagnostic cultures of blood or sputum before the administration of antibiotics. Symptoms of upper respiratory illness (URI) among residents before the pneumonia outbreak corresponded with elevation of antibodies to human parainfluenza virus 1 (HPIV1). In a matched case-control study, six of 10 case-patients, compared with five of 20 controls, had symptoms of URI during the preceding month (matched odds ratio (MOR) = 4.5, 95% CI = 0.8-33). Nine case-patients had serum available, and five of these had both serologic evidence of recent HPIV1 infection and recent URI, compared with two of 18 controls (MOR = 9.0, 95% CI = 1.2-208). Only three residents had documentation of pneumococcal vaccination. CONCLUSIONS Noninfluenza viral infections may play a role in the pathogenesis of some bacterial pneumonias. S. pneumoniae was the cause of at least two pneumonias; lack of preantibiotic cultures may have interfered with isolation of S. pneumoniae in others. Recent HPIV1 infection was epidemiologically linked to subsequently developing pneumonia. Spread of HPIV1 in the facility may have contributed to increased susceptibility to S. pneumoniae and, potentially, to other bacterial pathogens.

Abstract
A numerical method was applied to a system of differential rate equations describing the monomer-dimer-inhibitor (M-D-I) interaction involving human immunodeficiency virus type 1 protease and a peptidomimetic, competitive inhibitor. Two pairs of progress curves were obtained, one involving the M-D interaction and the other the M-D-I interaction. Each pair of reactions was designed to begin with extreme conditions and end at the identical equilibrium position. The results were compared with analytical (exact mathematical) methods reported previously. Good agreement between the two methods was observed at high- and low-salt conditions for the rates of monomer association and dimer dissociation. Not surprisingly, however, the major difference was observed in the analyses involving the M-D-I interaction, since analytical methods cannot account for dimer dissociation in the presence of inhibitor. While the estimates for the inhibitor off rate were comparable for high-salt conditions (where dimer dissociation is minimized), the analytical method underestimated this parameter for low-salt conditions by an order of magnitude, the consequence of mistaking inactive M for inactive DI.

Abstract
Enterocytozoon bieneusi is a microsporidian that causes a severe, debilitating, chronic diarrhea in some patients with the acquired immunodeficiency syndrome. Specific diagnosis of E. bieneusi currently requires an invasive biopsy procedure and time-consuming preparation of specimens for electron microscopy. Our attempts to establish an in vitro culture system using mammalian cell cultures inoculated with duodenal aspirates, biopsy, or both, from 2 infected patients resulted in inadvertent coculture of an adenovirus and E. bieneusi. The adenovirus-infected cells deceptively appeared to contain spores of microsporidia based on light microscopic examination. Transmission electron microscopy revealed only a few microsporidia, but numerous cells infected with an adenovirus that was subsequently identified as adenovirus type 8. We believe that adenovirus infections prevented the cultured cells from supporting the proliferation of E. bieneusi and ultimately destroyed the cell cultures.

Abstract
Sera from infants aged 5 to 11 months and from their mothers were used to investigate the level and duration of transplacentally derived measles antibody. The infants of foreign-born, inner-city mothers were more likely to have measles antibody and were less likely to get measles. Infants of foreign-born mothers, because they are less likely to respond to measles vaccine, may require different vaccine strategies than infants of mothers born in the United States.
