| prevalence of group a and group b rotaviruses in the feces of neonatal dairy calves from california. | 136 fecal samples, collected from 47 dairy calves on a calf ranch and in a dairy herd in california, were tested for the presence of group a and group b rotaviruses by reverse transcription-polymerase chain reaction (rt-pcr). samples were collected from each calf at days 1, 7 and 14. within the 14 day period, 44 calves (94%) were positive for group a rotavirus and an unexpectedly high number of calves (38 calves, 81%) were positive for group b rotavirus. when these samples were examined by polya ... | 1995 | 7621673 |
| enteric pathogens in intensively reared veal calves. | observations were made on development of diarrhea in special-fed calves (n = 460) on 8 commercial facilities during 2 successive 16-week production cycles at weeks 0, 2, 4, 8, 12, and 16. a total of 23% were affected, with peak number of calves with diarrhea observed at week 0. suspected enteropathogens were identified in 86% of these calves, most commonly cryptosporidia, coronavirus, and rotavirus. identified potential zoonotic pathogens included giardia and salmonella spp and verotoxigenic esc ... | 1994 | 7879973 |
| serotypic differentiation of rotaviruses in field samples from diarrheic pigs by using nucleic acid probes specific for porcine vp4 and human and porcine vp7 genes. | of 216 fecal and intestinal samples collected from nursing or weaned diarrheic pigs in the united states and canada, 57 were identified as group a rotavirus positive by rna electrophoresis and silver staining. fifty-seven and 52 rotavirus-positive samples were analyzed by hybridization with gottfried and osu pcr-derived gene 9 and 4 probes, respectively. only 17 samples were identified with either homologous vp4 (p)- or vp7 (g)-coding genes or both. one rotavirus identified as g4 and p7 was simi ... | 1994 | 8150940 |
| epidemiology of diarrheal disease among children enrolled in four west coast health maintenance organizations. vaccine safety datalink team. | we used information from the vaccine safety datalink (vsd) about approximately 1 million children enrolled in four health maintenance organizations to assess the morbidity from diarrhea and estimate the disease burden of rotavirus. | 1998 | 9686726 |
| trends in intussusception-associated hospitalizations and deaths among us infants. | the newly licensed tetravalent rhesus-human reassortant rotavirus vaccine has been withdrawn following reports of intussusception among vaccinated infants. | 2000 | 11099597 |
| lack of association between rotavirus infection and intussusception: implications for use of attenuated rotavirus vaccines. | withdrawal of the tetravalent rhesus-human rotavirus vaccine rotashield because of its association with intussusception raised concerns about a potential link between natural rotavirus disease and intussusception. our objective was to determine whether such an association exists. | 2002 | 11840074 |
| clinical presentations of rotavirus infection among hospitalized children. | although rotaviruses (rvs) are the most common cause of severe gastroenteritis in children, there is a lack of information detailing the spectrum of clinical manifestations of rv disease resulting in hospitalization. | 2002 | 12005086 |
| hexamita meleagridis (spironucleus meleagridis) infection in chukar partridges associated with high mortality and intracellular trophozoites. | an outbreak of infectious catarrhal enteritis, associated with the flagellated protozoan spironucleus meleagridis (syn. hexamita meleagridis), is reported from a commercial flock of chukar partridges in california. the disease affected birds between the ages of 4 and 6 wk and resulted in diarrhea, listlessness, depression, and high mortality. concurrent infection with other intestinal pathogens, including cryptosporidia, group e salmonella, long-segmented filamentous microorganisms (lsfmos), and ... | 2004 | 15529998 |
| electron microscopic identification of viruses associated with poult enteritis in turkeys grown in california 1993-2003. | poult enteritis (pe) is one of the most common diseases seen in young turkey flocks. since 1993, more than 1800 cases of suspected pe have been submitted for examination by negative stain electron microscopy; this has involved more than 2400 individual results, because in many cases more than one virus was identified; at least 1500 individual results were positive for viruses. viruses have been identified in poults as young as 3 days and up to 9 wk of age. the most commonly found viruses are rot ... | 2008 | 18646448 |
| burden of rotavirus disease among children visiting pediatric emergency departments in cincinnati, ohio, and oakland, california, in 1999-2000. | we assessed the incidence of rotavirus disease requiring an emergency department visit among children <5 years of age. | 2008 | 18977975 |
| evaluation of seasonal patterns of kawasaki syndrome- and rotavirus-associated hospitalizations in california and new york, 2000-2005. | kawasaki syndrome (ks) is an uncommon childhood disease with unknown etiology. it has been suggested that rotavirus infection may play a causative role in the development of ks. | 2009 | 19835612 |
| sequencing and phylogenetic analysis of the coding region of six common rotavirus strains: evidence for intragenogroup reassortment among co-circulating g1p[8] and g2p[4] strains from the united states. | the segmented genome of rotaviruses provides an opportunity for rotavirus strains to generate a large genetic diversity through reassortment; however, this mechanism is considered to play little role in the generation of mosaic gene constellations between wa-like and ds-1-like strains in genes other than the neutralization antigens. a pilot study was undertaken to analyze these two epidemiologically important strains at the genomic level in order to (i) identify intergenogroup reassortment and ( ... | 2011 | 21264876 |
| [Current events in vaccination]. | The annual meeting of the Infectious Disease Society of America (IDSA) ; which brought together nearly 5000 participants from over 80 countries in Vancouver, Canada, October 21 to 24, 2010 ; provided a review of the influenza (H1N1) 2009 pandemic, evaluated vaccination programmes and presented new vaccines under development. With 12,500 deaths in the United States in 2009-2010, the influenza (H1N1) 2009 pandemic was actually less deadly than the seasonal flu. But it essentially hit the young, an ... | 2011 | 22019286 |
| mass screening of cattle sera against 14 infectious disease agents, using an elisa system for monitoring health in livestock. | mass screening elisa methods were developed for testing cattle serum for antibodies against 14 common livestock diseases simultaneously. the absorbance values were transformed to a %elisa (spectrophotometric antibody end point) by a computer interfaced with a microplate reader. a histogram indicating a cutoff point and a report for the veterinarian also was generated. the computer program produced a print-out of the antibody profile for each animal tested, the antibody concentration against each ... | 1991 | 1767993 |
