| the clinical presentations of rocky mountain spotted fever. comments on recognition and management based on a study of 63 patients. | rocky mountain spotted fever continues to increase in the united states and the case-fatality ratio remains unchanged despite the availability of effective antibiotics. the apparent reason for the continuing deaths from this disease is the failure of physicians to consider the diagnosis in patients presenting with febrile exanthems in the late spring and summer months. a clinical diagnosis should be based on the history of tick exposure and the presence of fever and the typical exanthem. serolog ... | 1978 | 679582 |

| structure and replication of echovirus type 12. 1. analysis of the polypeptides and rna of echovirus 12 particles. | the propagation of echovirus 12 in green monkey kidney (gmk) cells, a continuous cell line, is described. virions and empty capsids are purified to homogeneity by cscl density and by velocity centrifugation. the protein composition of the particles as compared to poliovirus 2 particles is analyzed by dodecyl sulfate/polyacrylamide gel electrophoresis. infectious virions were found to be composed of four different polypeptide chains of molecular weights 33,000, 31,000, 24,000 and 7,000. some addi ... | 1978 | 729593 |
| structure and replication of echovirus type 12. 2. viral polypeptides synthesized in the infected cell. | a technique has been devised which allows us to label predominantly echovirus-12-specific proteins: upon infection in the presence of d-(--)-2-(alpha-hydroxybenzyl)benzimidazole plus actinomycin d the shut-off of host-cell protein synthesis takes place as in infected, untreated cells, but the bulk of viral protein synthesis is inhibited. upon removal of 2-(alpha-hydroxybenzyl)benzimidazole a peak of viral protein synthesis is visible 3 h later. the time course of appearance of viral proteins is ... | 1978 | 729594 |

| congenital tremor in pigs in sweden. a case report. | the authors describe an outbreak of congenital tremor in piglets in a herd for the integrated production of fattening pigs. all sows farrowing within a period of slightly over a month gave birth to piglets affected to a varying degree. all the sows were of the swedish land race and covered by boars representing two different lines not genetically related to each other. the case history comprised information on oral treatment of the sows with an antiparasitic trichlorfon compound (neguvon) during ... | 1978 | 733481 |
| paralytic poliomyelitis in the gaza strip and west bank during recent years. | numerous cases of paralytic poliomyelitis occurred during epidemic years and in interepidemic periods in recent years in the gaza strip and the west bank. during the epidemics of 1974 and 1976, more than 100 paralytic cases were recorded each year. the dominant poliovirus was type 1. in interepidemic years, especially in the gaza strip, type 3 poliovirus was the prevalent type. the age group affected were infants and children up to 3 years and 50% of cases occurred during the first 12 months of ... | 1978 | 753648 |

| antigenicity and polypeptide composition of native and heated echovirus type 7 procapsids. | the native procapsid (naturally occurring empty capsid) of echovirus type 7 (e7) possesses n-antigenicity, which is as highly strain-specific as the native virion. when the native procapsid is heated, its antigenicity is converted to h-antigenicity which is common among strains of e7 and thus type-specific. however, no difference was detected in the sedimentation rate (80s) and polypeptide composition (vp0, 1 and 3) of the native and heated procapsids. | 1979 | 759555 |
| [the mechanism of plaque production by enteroviruses under bentonite overlay. relationship between plaque production and the dynamics of intracellular virus reproduction and membrane potential of the host cell]. | the association of plaque production under bentonite overlay with the cycle of intracellular reproduction of enteroviruses and the dynamics of the membrane potential of infected cells was studied. it was shown that by the time of termination of the intracellular enterovirus reproduction cycle (4 1/2-5 hours postinfection) bentonite particles were torn away from the cell surface. at the same time the membrane potential of the host cell began to decline progressively. the data obtained explain the ... | 1975 | 769340 |
