Microbiology (non-medical)

The fact that none of the known DNA polymerases is able to initiate DNA chains but only to elongate from a free 3' -OH group raises the problem of how replication is initiated, both at the replication origin and on Okazaki frag- ments.

In diesem Buch werden die verschiedenen Viren (Hepatitis-B-Virus, Hepatitis-Non-A-Non-B-Viren, Cytomegalievirus, Epstein-Barr-Virus, Papovaviren, HIV), die Blut, Plasma und Plasmapräparate kontaminieren können, besprochen.

Genetic constraints on adaptive evolution can be understood as those genetic aspects that prevent or reduce the potential for natural selection to result in the most direct ascent of the mean phenotype to an optimum.

Die durch das menschliche Immundefektvirus HIV verursachte erworbene Immunschwäche AIDS gewinnt aufgrund steigender Erkrankungszahlen zunehmend an praktisch-ärztlicher Bedeutung.

Crystalline surface layers (S-layers) represent an almost universal feature of archaebacterial cell envelopes and can be found in gram-positive and gram-negative eubacterial species from nearly all phylogenetic branches.

During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology.

In recent years, papillomaviruses in general and human papillo- maviruses in particular have been recognized as possible agents of important diseases, including some forms of human cancer.

The Plant Root and the Rhizosphere was a major topical feature of the first International Symposium on Factors Determining the Behavior of Plant Pathogens in Soil held at the University of California, Berkeley in 1963.

The contributions to this book derived from the Seventh Munich Symposium on Microbiology on June 3 and 4, 1981, which was organized by the WHO Centre for Collection and Evaluation of Data on Comparative Virology at the Institute of Medical Microbiology, Infectious and Epidemic Diseases, University of Munich, Federal Repub- lic of Germany.

A puzzling epidemiological problem was the driving force behind the discovery of human adenoviruses by Wallace Rowe and his colleagues 30 years ago.

Binding of various ligands (hormones, neurotransmitters, immunological stimuli) to membrane receptors induces the following changes: 1.

The present atlas is addressed mainly to those who, departing from different spheres of interest, are studying the dispersal of fungus spores in the air, like aero biologists, plant pathologists, medical mycologists, allergologists, or those interested in spore morphology as a taxonomic tool.

For more than ten years cell fusion techniques have been applied in studies on various lymphocyte functions.

A knowledge, which is as accurate as possible of microbial ecology is indispensible for ecosystem research and environmental protection.

The plan for this atlas evolved from the necessity of providing the biology student interested in protozoology, cytology, and para- sitology with an introduction to the study of fine structure in Protozoa.

Expression of an immune response is the net result of complex synergis- tic and antagonistic activities performed by a variety of cell types.

Prominent progress in molecular biology was only made when it became possible to separate functionally distinct molecules by taking advantage of their biophysical properties.

Four decades ago, lymphocytic choriomeningitis virus was discovered, at about the same time and independently, in 3 different localities in the U.

When I prepared the first German edition of this book in 1955, it was my intention to acquaint biologists in my country with the new and exciting results being obtained on the other side of theAtlantic Ocean (incl.

Reaction Centers of Photosynthetic Bacteria is an updated record on the most recent insight into the struc- ture/function relationship of reaction centers from photosynthetic bacteria.

General pathologists see many biopsies from transplanted organs but few are in large enough centres so that this forms the bulk of their work.
