Microscopic colonization

Nuclear alterations are a well-known manifestation of cancer. However, little is known about the early, microscopically-undetectable stages of malignant transformation. Based on the phenomenon of field cancerization, the tissue in the field of a tumor can be used to identify and study the initiating events of carcinogenesis.

Metastatic dissemination can exist before a pathologically and clinically detectable manifestation. The structural heterogeneity of colon cancer (CC) in histological sections with respect to the morphology of tumor aggressiveness and composition of the tumor microenvironment raises the question of whether the microscopical tumor architecture enables a discrimination of groups with different metastatic potential.

In Groundnut aflatoxin contamination is a major problem which affects the quality of the seed. These aflatoxins have carcinogenic, hepatotoxic, teratogenic and immunosuppressive effects which were produced by Aspergillus flavus and A. parasiticus. For the management of aflatoxin problem in groundnut, use of plant growth-promoting rhizobacteria (PGPR) is a viable and sustainable option. Our present study is aimed at determining the mode of action of these PGPR (Pseudomonas fluorescens) using Scanning Electron Microscope (SEM). A superior P.

The Microvirga zambiensis strain WSM 3693 is an endophytic strain isolated from saline area of kutch, Gujarat. The green fluorescent protein (GFP) was used to mark this endophyte in order to visualize and analyze the colonization processes in vivo. After inoculation for 2 to 15 d, it was visualized in cotton tissue using fluorescence microscopy.

Diagnostic Microbiology In patients with community-acquired pneumonia, a pneumococcal etiology is strongly suggested by the microscopic demonstration of large numbers of PMNs and slightly elongated gram-positive cocci in pairs and chains in the sputum. A sample such as the one shown in Fig. 128-2 is highly specific for pneumococcal infection of the lower airways. In the absence of such microscopic findings, the identification of pneumococci by culture is less specific, possibly reflecting colonization of the upper airways.
