1. Papel das hemaglutininas 67-72p de Corynebacterium diphtheriae na ligação a proteínas plasmáticas, superfícies celulares, invasão e indução de apoptose / Participation of hemagglutinin 67-72p of corynebacterium diphtheriae in binding to plasma proteins, cells surfaces, invasion and induction of apoptosis
Corynebacterium diphtheriae pode ser isolado tanto de quadros de difteria clássica, quanto de infecções sistêmicas, como endocardite. O fibrinogênio (Fbn) e a fibronectina (Fn) são glicoproteínas presentes na matriz extracelular de tecidos conjuntivos. A influência destas proteínas na patogênese das infecções locais e invasivas causadas por C. di

2. Fibrinogen binds to nontoxigenic and toxigenic Corynebacterium diphtheriae strains
The production of fibrinous exudates may play an important role in determining the outcome of bacterial infection. Although pseudomembrane formation is a characteristic feature of diphtheria, little is known about the fibrinogen (Fbn)-binding properties of Corynebacterium diphtheriae strains and the influence of the gene that codes for diphtheria toxin (tox

3. Studies of the small bowel surface by scanning electron microscopy in infants with persistent diarrhea
We describe the ultrastructural abnormalities of the small bowel surface in 16 infants with persistent diarrhea. The age range of the patients was 2 to 10 months, mean 4.8 months. All patients had diarrhea lasting 14 or more days. Bacterial overgrowth of the colonic microflora in the jejunal secretion, at concentrations above 10(4) colonies/ml, was present i

4. Faecal toxin and severity of antibiotic-associated pseudomembranous colitis.
The relationship between faecal toxin titre, histological evidence of pseudomembrane in the rectum, and severity of antibiotic-associated colitis has been analysed from data on 62 patients whose faeces contained Clostridium difficile toxin. There was a significant correlation between a toxin titre of 6400 or more and the presence of pseudomembrane (p less th

6. Suicidal Membrane Repair Regulates Phosphatidylserine Externalization during Apoptosis*♦
One of the hallmarks of apoptosis is the redistribution of phosphatidylserine (PS) from the inner-to-outer plasma membrane (PM) leaflet, where it functions as a ligand for phagocyte recognition and the suppression of inflammatory responses. The mechanism by which apoptotic cells externalize PS has been assumed to involve “scramblases” that randomize phos

7. Epidemic keratoconjunctivitis and chronic papillary conjunctivitis in London due to adenovirus type 19.
Since July 1973 cases of keratoconjunctivitis resembling epidemic keratoconjunctivitis were observed in the External Eye Disease Clinic at Moorfields Eye Hospital; City Road, London. Adenovirus type 19 was isolated in human embryonic kidney cells from 21 patients. The majority were males between 20 and 40 years old. A small hospital outbreak involving six pa

8. Diarrhea induced by Treponema hyodysenteriae: a young chick cecal model for swine dysentery.
The experimental infection of 25 young chicks with Treponema hyodysenteriae was carried out. Treponemes were isolated from 21 of 25 chicks on day 21 after inoculation. The ceca of chicks infected with treponemes were atrophied. The lumen was filled with a white watery fluid instead of digested feed. In some infected chicks, a cecal core was observed with the
