the distribution and characterization of group b streptococci in new york b streptococcal isolates from bovine mastitis were classified according to the lancefield typing scheme. three types were found in new york state dairy herds; ia, ii and iii. the distribution within these types varies from area to area, however, on a state-wide basis ia is the most prevalent (69.6%) followed by type ii (16.7%) and type iii (10.1%). within a single herd one type predominants with only slight incidence of other types. attempts to determine distinguishing characteristics betw ...1976770075

isolation of s-n-butylcysteine sulfoxide and six n-butyl-containing thiosulfinates from allium siculum.isolation and identification of (s(s)r(c))-s-n-butylcysteine sulfoxide (1) from the bulbs of allium siculum is reported. this compound was found in all parts of the plant (bulbs, stem, leaves, and flowers) along with known compounds (s(s)r(c))-s-methyl- and (r(s)r(c))-(e)-s-(1-propenyl)cysteine sulfoxides (2 and 3, respectively). in addition, six n-butyl-containing thiosulfinates (4-9) have been found in a ch2cl2 extract of the bulbs. structures were determined by a combination of spectral metho ...200212141853
trends in methicillin-resistant staphylococcus aureus anovaginal colonization in pregnant women in 2005 versus 2005, the prevalence of methicillin-resistant staphylococcus aureus (mrsa) anovaginal colonization in pregnant women at our center (columbia university medical center) was 0.5%, and mrsa-colonized women were less likely to carry group b streptococcus (gbs). in this study, our objectives were to identify changing trends in the prevalence of mrsa and methicillin-susceptible s. aureus (mssa) anovaginal colonization in pregnant women, to assess the association between mrsa and gbs colonization, a ...201020686089

compliance with group b streptococcal disease prevention guidelines.this study assessed the degree of clinician compliance with nationally recommended guidelines for the prevention of early onset group b streptococcal (gbs) disease in infants. a secondary objective was to identify areas for specific educational interventions to enhance clinician compliance.200111725403
selecting linear-score distributions for modelling milk-culture results.the data for this cross-sectional retrospective study are from surveys of 65 dairy-cattle herds in central new york, usa sampled between february, 1993 and march, 1995. the objective was to identify probability distributions of logarithmically transformed somatic-cell counts (linear score) for use in a simulation model of mastitis and milk quality. probability density functions were estimated using maximum-likelihood estimators for the linear score of individual-cow composite-milk samples cultur ...19989500161

bovine mastitis pathogens in new york and pennsylvania: prevalence and effects on somatic cell count and milk production.milk samples were collected from 108,312 dairy cows during 1601 farm visits made between january 1991 and june 1995. the herd visits were made by personnel from the central laboratory of the quality milk promotion services at cornell university (ithaca, ny) to farms located in central new york and northern pennsylvania. dairy herd improvement association records were available for 32,978 cows in 327 herds. intramammary infections, as defined by positive milk cultures, were present in 48.5% of al ...19979361234
the changing spectrum of group b streptococcal disease in infants: an eleven-year experience in a tertiary care hospital.risk factors, clinical syndromes and the case-fatality rates associated with group b streptococcus (gbs) infections in infants managed at the university of rochester medical center during 1979 to 1989 were reviewed. overall 92 episodes of early onset disease (eod) and 54 of late onset disease (lod) were diagnosed in 143 infants (3 infants with eod presented later with lod). about one-third of patients with eod and controls were non-white compared with two-thirds of patients with lod that occurre ...19911749691
