Ongoing scientific research in many parts of the world on the genomics, proteomics and genetic engineering of LAB is increasing our understanding of their physiology, pushing further the boundaries for their potential applications. "Lactic Acid Bacteria - R&D for Food, Health & Livestock Purposes" is a compilation and discussion of the outstanding scientific research activities concerning actually and future applications of LAB. It is directed to a vast public of readers - researcher, academics, corporate R&D, students or just curious interested in the subject....
Bacteria that associate with plants are diverse in their ability to affect plant health, their genotypic and phenotypic characteristics, and their phylogeny. These bacteria are typically members of complex microbial communities, with only a few establishing pure clonal populations within a plant.

Harrison's Internal Medicine Chapter 140. Infections Due to the HACEK Group and Miscellaneous Gram-Negative Bacteria
The HACEK Group HACEK organisms are a group of fastidious, slow-growing, gram-negative bacteria whose growth requires an atmosphere of carbon dioxide. Species belonging to this group include several Haemophilus species, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae. HACEK bacteria normally reside in the oral cavity and have been associated with local infections in the mouth.
Other Gram-Negative Bacteria
A. xylosoxidans (previously Alcaligenes xylosoxidans) is probably part of the endogenous intestinal flora and has been isolated from water sources. Immunocompromised hosts, including patients with cancer and post-
chemotherapy neutropenia, cirrhosis, and chronic renal failure, are at increased risk. Nosocomial outbreaks of A. xylosoxidans infection have been attributed to contaminated fluids, and clinical illness has been associated with isolates from many sites, including blood (often in the setting of intravascular devices).
Bacteria are microscopic, single-celled organisms that are the most numerous organisms on earth. They are so small that over five million could be placed on the head of a pin. Bacteria can live in numerous environments and perform many complex actions, some of which are beneficial and some harmful. Most bacteria, however, are not harmful and do not cause human health problems. Those that are disease producing are referred to as pathogenic. Viruses and some protozoans can also be pathogenic.
Sixty-six acetic acid bacteria (AAB) were isolated from fourty-five flowers and fruits collected in Hochiminh City, Vietnam. Of the sixty-six, thirty-one isolates were selected as dihydroxyacetone (DHA)-producing AAB based on the reaction with Fehling’s solution and grouped into three groups by routine identification with phenotypic features.

Abstract This study was conducted in order to evaluate the probiotic properties of lactic acid bacteria (LAB) isolated from intestinal tract of broilers and Thai indigenous chickens. The major properties, including the gastric juice and bile salts tolerance, starch, protein and lipid digesting capabilities, and the inhibition on certain pathogenic bacteria were investigated. Three-hundred and twenty-two and 226 LAB strains were isolated from ten broilers and eight Thai indigenous chickens, respectively....

ABSTRACT Bacillus spp. were isolated from the intestine of black tiger shrimp Penaeus monodon which were collected from the Gulf of Thailand at Chonburi province area during October 2005 to September 2006. The bacterial antagonist activity were tested with aquacultural pathogenic bacteria. The cross streak method results showed that Bacillus W803 and Bacillus W120 could inhibit Aeromonas hydrophila AQAH after 24 hours.

Because of the frequent, often daily, exposure to a large number and diversity of
pathogens (disease-causing agents), wastewater personnel have general and specific
concerns related to the potential health hazards presented by pathogens. Pathogens
commonly found in wastewater and of concern to wastewater personnel include
viruses, bacteria, fungi, protozoans, and helminths. Allergens, endotoxins, and exotoxins
are also found in wastewater and represent a concern to wastewater personnel.

Since the first edition of this book was published the popular idea of bacteria to which attention was drawn in the original preface has undergone considerable modification. Experimental medicine has added constantly to the list of diseases caused by bacterial organisms, and the general public has been educated to an adequate conception of the importance of the germ as the chief agency in the transmission of disease, with corresponding advantage to the efficiency of personal and public hygiene. At the same time knowledge of the benign bacteria and the enormous role
