Enumeration ofStreptococcus faecalis, with particular reference to polluted waters

Constrictive pericarditis with particular reference to etiology.

Phagocytosis, with particular reference to encapsulated bacteria.

The phagocytic cells of the mammalian host provide a remarkable defense against a wide variety of bacteria, fungi, and protozoa. Whether they play a protective role in infections caused by viruses and rickettsiae is at present a matter of conjecture. The discovery of "pinocytosis" (Gey, 1954), however, and recent observations relating to bacterial endotoxins (Berthrong and Cluff, 1953; Braude e...

Investigation of Dual Fuel Diesel Engine With Particular Reference to Engine Cycle Model

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...

Comparison of PCR and plaque assay for detection and enumeration of coliphage in polluted marine waters.

A total of 68 marine samples from various sites impacted by sewage and storm waters were analyzed by both the plaque assay and a reverse transcriptase (RT) PCR technique for F(sup+)-specific coliphage. The coliphage levels detected by the plaque assay averaged 1.90 x 10(sup4) PFU/100.0 ml. Using a most probable number (MPN) PCR approach, the levels averaged 2.40 x 10(sup6) MPN-PCR units/100.0 m...

Platichthys flesus in Dutch coastal and estuarine waters , with particular reference to environmental stress factors . I . Epizootiology of gross lesions

In order to investigate potential links between marlne pollution and fish diseases, an ep~zootiological study was conducted in The Netherlands during 1983-89. This study concentrated on grossly identifiable diseases of flounder Platichthys flesus. Flounder were found to be affected by the viral skin disease lymphocystis and by skin ulcers probably of bacterial origin. Overall prevalences of the...
