| protective effects of supplemental vitamin e against infection. | vitamin e supplementation (dl-alpha-tocopheryl acetate except where noted) in excess of requirement significantly increased humoral immune response or disease resistance. mice immunized with sheep red blood cells or tetanus toxoid and fed the supplemental vitamin demonstrated increased plaque-forming cells (pfc) and hemagglutinin (ha) titers. a vitamin e deficiency resulted in decreased pfc and little igg which was partially corrected by n,n-diphenyl-p-phenylenediamine but not as effectively as ... | 1979 | 376353 |

| experimental pneumonia in red deer (cervus elaphus l) produced by an ovine chlamydia. | an isolate of chlamydia psittaci from ovine pneumonia produced extensive pneumonia in red deer after endobronchial inoculation. associated clinical signs lasting for several days included pyrexia, inappetance, increased pulse and respiration rate, and physical distress after handling, but no coughing or upper respiratory symptoms. histologically, an acute exudative reaction was present after two days, and an early proliferative response after seven days. both the clinical and pathological respon ... | 1979 | 532073 |
| [a method for the preparation of a chlamydiae group-specific antigen on hela-229 cells infected with a strain of "chlamydia trachomatis" for use in the complement fixation test (author's transl)]. | a simple method for the preparation of a potent group-specific antigen on hela-229 cells infected with mrc-1 (lb) (tric/gb/mrc-1 gf) strain of chlamydia trachomatis is outlined. hela-229 cells are infected (mrc-1 strain, 102 inclusion-forming units per cell) with centrifugation at 4,000 g for 1 h in flat-bottomed vials. the cells are removed by brief trypsinization with 0.25% trypsin and put into 75 cm2 culture flasks (12 x 106 cells by flask) in bhk-21 medium supplemented with foetal bovine ser ... | 1979 | 533072 |
| chlorhexidine as an effective agent against chlamydia trachomatis in vitro and in vivo. | in a small field trial, chlorhexidine (50 micrograms/ml) was as effective against clinical trachoma as topical tetracyclines or oral co-trimoxazole; in vitro, 2.5 micrograms/ml was chlamydicidal. | 1979 | 533265 |

| clinical evaluation of a commercial vaccine against chlamydial abortion of ewes. | the immunity of ewes vaccinated prior to breeding with an adjuvant vaccine prepared from yolk sac propagated chlamydiae, was challenged at 70 days of pregnancy by intravenous (iv) or intradermal (id) inoculation of a suspension of virulent yolk sac propagated chlamydiae. the response to challenge inoculation was followed by recording rectal temperature, cf antibody titer, lambing performance and by chlamydial isolation from vaginal swabs. that vaccine did not protect against iv challenge: 7 of 1 ... | 1979 | 539776 |

| infection of untreated primary human amnion monolayers with chlamydia trachomatis. | for development of a laboratory model for chlamydial infection of the human genital tract, untreated primary human epithelial cell monolayers, prepared from each of four placentas, were infected with a stock strain of chlamydia trachomatis isolated from the nasopharynx of an infant with pneumonia. infectivity titrations were performed with use of standard procedures of chlamydial inoculation, and inclusions grown in amnion cell monolayers and in mccoy cells were measured versus infectious units ... | 1979 | 541524 |

| experimental transmission of chlamydia psittaci to turkeys from wild birds. | wild birds were inoculated with chlamydia psittaci to determine species that could be potential hosts and vectors in transmitting the agent to domestic turkeys. infection occurred in turkeys exposed to starlings (sturnus vulgaris), common grackles (quiscalus quiscula), brown-headed cowbirds (molothrus ater), and inca doves (cardafella inca). mourning doves (zenaidura macroura) shed the agent sparingly, but turkeys exposed to them did not become infected, these findings and knowledge of the habit ... | 1979 | 546413 |
| the aetiology of a keratoconjunctivitis occurring in goats in the sudan. | an infectious keratoconjunctivitis occurring in goats in the sudan is described. experimental transmission using infective ocular discharges resulted in a conjunctivitis in young kids and a severe keratoconjunctivitis in an adult goat. a pleomorphic organism which resembled rickettsia spp was found in conjunctival smears from naturally and experimentally infected animals. neither mycoplasma nor chlamydia spp were isolated in microbiological cultures. | 1979 | 552726 |
| field studies on enzootic abortion of ewes in south east scotland. | statistical data were collected from 20 sheep flocks in which enzootic abortion of ewes (eae) was diagnosed by examination of fetal material and maternal blood samples. the abortion rate in the 10,645 ewes in these flocks was 7.6 per cent. thirteen of the flocks were fully vaccinated against eae but the abortion rate in these was still in the order of 6.5 per cent. eae was the major cause of the problem as ascertained from the laboratory examination of samples from a wide range of cases of abort ... | 1979 | 552732 |
| [the replication cycle of chlamydia trachomatis and chlamydia psittaci: ultrastructural analysis]. | an ultrastructural comparative analysis is reported on the replication cycle of six strains of chlamydia trachomatis, recently isolated, and chlamydia psittaci strain 6bc, grown in cell cultures. important morphological distinctions of the bacterial walls are documented. in chlamydia trachomatis the cell wall seems more rigid. this causes, during the morphogenesis of the elementary body, its separation from the cell membrane with formation of an electron transparent space, which is not demonstra ... | 1979 | 553521 |

| chlamydia trachomatis in cell culture. ii. susceptibility of seven established mammalian cell types in vitro. adaptation of trachoma organisms to mccoy and bhk-21 cells. | trachoma organisms of serotype b were grown serially in irradiated cells (mccoy, bhk-21, microbiological associates, and bhk-21, lister) and tested for infectivity in monolayers of five mammalian cell lines (bhk-21, cho, hela s3, mccoy and owmk) and two diploid strains (st/btl and wi-38). all cell types had low susceptibility to chlamydial infection but the number of inclusions increased when the inoculum was centrifuged onto the monolayers, or when the cells were irradiated. infection was highe ... | 1977 | 559642 |

| growth of chlamydia psittaci in macrophages. | survival and growth of l-cell-cultivated chlamydia psittaci occurred in mouse macrophages in vitro. two major factors governing the intracellular fate of chlamydiae in macrophages are: (i) the multiplicity of infection (moi), i.e., the elementary body (eb)-to-macrophage ratio, and (ii) the state of the eb. at a low moi (1:1) survival and growth of live, untreated chlamydiae were optimal. the chlamydiae were internalized in macrophages within 30 to 40 min. eb proceeded to differentiate into retic ... | 1978 | 565338 |
| interaction of chlamydia psittaci with mouse peritoneal macrophages. | l-cell-grown chlamydia psittaci elementary bodies (eb) were rapidly phagocytized by mouse peritoneal macrophages in vitro. however, the intracellular fate of chlamydiae in macrophages appeared to be dependent on the multiplicity of infection (moi), i.e., the eb-to-macrophage ratio, and the treatment of the eb. at an moi of 1:1 or less, survival is maximal, and growth and multiplication of live, untreated chlamydiae did occur. in contrast, at a high moi (100:1), survival of chlamydiae is reduced, ... | 1978 | 565339 |
