pathological and microbiological studies on calf pneumonia occurring in mass rearing facilities.pathological and microbiological studies were conducted on lesions in the lungs of 194 calves from mass rearing facilities. macroscopically, the lesions were classified into six forms: nonlesion, atelectasis, mild pneumonia, moderate pneumonia, advanced pneumonia, and advanced pneumonia accompanied with abscess. histopathological examination revealed bronchopneumonia in most of the calves. lesions more advanced than moderate pneumonia were complicated with desquamation, severe exudation, and nec ...1979522891
immunity to lancefield's group e. streptococcus: flank inoculation of susceptible and immune swine.healthy swine flank inoculated with lancefield's group e streptococcus sp developed characteristic signs of streptococcal lymphadenitis of swine; however, abscesses were found in prefemoral lymph nodes rather than in cervical lymph nodes. after 6 months, swine (recovered from the cervical form of streptococcal lymphadenitis of swine caused by oral exposure to group e streptococcus) were flank inoculated with group e streptococcus sp. only transitory signs of diseases developed and abscesses did ...1978629468
immunity to lancefield's group e streptococcus: passive protection of swine.healthy swine from one source were randomly allotted to 3 groups of 3 pigs each. troup i and ii pigs were parenterally dosed with serum obtained from swine in the convalescent stage of streptococcic lymphadenitis of swine. group iii pigs were contact controls. the swine of all groups were orally exposed to lancefield's group e streptococcus sp. during the next 3 weeks, the controls evidenced little resistance to the development of streptococcic lymphadenitis of swine, whereas the principals evid ...1978677537
bacteriology of human experimental gingivitis: effect of plaque and gingivitis score.the plaque flora isolated from discrete dentogingival sites during a human gingivitis experiment was analyzed as a function of the plaque score and of the gingivitis score. when the gingivitis score was plotted as a function of the plaque score, a nonbleeding gingivitis was associated with a proportional increase in the actinomyces sp. at the expense of the streptococcus sp. in particular, the percentage of actinomyces israelii increased significantly, while the percent streptococcus sanguis dec ...1978711337

infection and mortality in captive wild-trapped canvasback ducks.fungal, bacterial and malarial infections, as well as malnutrition caused heavy mortality in a group of wild-trapped canvasbacks (aythya valisineria) held in 10 x 3 x 2 m open-water pens. deaths occurred between 21 and 158 days after confinement and were associated with infections of aspergillus fumigatus, escherichia coli, staphylococcus sp., streptococcus sp., klebsiella sp., enterobacter sp., and plasmodium sp. infection and mortality was believed to result from reduced resistance associated ...19761255909
novel streptococcal-integration shuttle vectors for gene cloning and new streptococcal integration shuttle vectors have been constructed which contain different antibiotic-resistance-encoding genes capable of expression in both streptococcus sp. and escherichia coli. these plasmids can replicate in e. coli, but not in streptococci because of the absence of a streptococcal origin of replication. the size, antibiotic resistance, and number of unique restriction sites available for cloning for each plasmid are as follows: psf141 (7.6 kb, cmr and kmr, 7 sites), ...19921327968
protein v, a novel type-ii igg receptor from streptococcus sp.: sequence, homologies and putative fc-binding site.we have cloned and sequenced the fc-receptor-encoding gene, fcrv, from a group g streptococcus. considerable similarity was revealed between the fcrv, fcra76 and m proteins of group a streptococci in their signal sequences and 3' termini, and between the fc-binding regions of fcrv and fcra76. the promoter and terminator regions showed no homology with those of the fcra76 and m protein-encoding genes. the a1-a4 domains of fcrv (protein v) exhibit a heptapeptide repeat motif which is characteristi ...19921398120
prevention of c3 deposition by capsular polysaccharide is a virulence mechanism of type iii group b streptococci.strains of type iii group b streptococci isolated from patients with neonatal sepsis are generally resistant to complement-mediated phagocytic killing in the absence of specific antibody. it has been suggested that the resistance of type iii group b streptococci to phagocytosis results from inhibition of alternative-complement-pathway activation by sialic acid residues of the type iii polysaccharide. to better define the relationship between structural features of the type iii capsule and resist ...19921398910
