To the Editor: Moraxella osloensis is an aerobic, gram-negative, lactose-nonfermenting coccobacillus. It is a commensal of the human upper respiratory tract and occasionally of the skin and urogenital tract ().Unlike M. catarrhalis, M. osloensis is rarely pathogenic in humans. However, several cases of serious infections caused by this organism have been documented (2–6). IntechOpen is a leading global publisher of Journals and Books within the fields of Science, Technology and Medicine. We are the preferred choice of o authors worldwide.
Moraxella is a genus of Gram-negative bacteria in the Moraxellaceae family. It is named after the Swiss ophthalmologist Victor organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase-positive, and catalase-positive properties. M. catarrhalis is the clinically most important species under this : Gammaproteobacteria. Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella.

Atypical Moraxella strains were significantly more resistant to Ch and Am. Moraxella strains were more resistant to PEA than were other gram negative bacteria of fishery origin.
At a concentration of mmoles PEA/1iter, Moraxella strains were not affected; however, an Arthrobacter strain of marine origin was totally inhibited and marine Pseudomonas strains showed an extended lag : Stephen M. Vernon.
Nutritional and biochemical characterization of Moraxella species isolated from fishery sources. Abstract. Graduation date: One hundred and fourteen strains of Moraxella species isolated\ud from marine fishery sources were investigated to determine the cause\ud of this organism's predominance in seafood.
The nutritional requirements. A number of nutritional and biochemical properties of more than strains of the oxidase-negative moraxellas (the Mima-Herellea-Acinetobacter group of bacteria) were studied.
These properties included the range of carbon sources that can support growth, the utilization of nitrate, the production of proteolytic and lipolytic enzymes, and the reactions involved in the oxidation of sugars and of aromatic Cited by: Bacteria of the genus Moraxella have been isolated from a variety of mammalian hosts.
In a prior survey of bacteria that colonize the rhesus macaque nasopharynx, performed at the Tulane National Primate Research Center, organisms of the Moraxella genus were isolated from animals with epistaxis, or “bloody nose syndrome.” They were biochemically identified as Moraxella catarrhalis, Cited by: 9.

The biochemical characterization with. Introduction. Members of the genus Moraxella are Gram-negative, aerobic, asaccharolytic bacteria that can be pleomorphic, resistant to Gram-stain decolorization, and occur predominantly in pairs or short chains.
Those of the subgenus Branhamella (e.g. Moraxella catarrhalis) are small (– μm) cocci, whereas organisms of the subgenus Moraxella are larger (– × – μm. Some Moraxella species are gram-negative bacilli. catarrhalis is the most important pathogen of this genus (Table ). Pathobiology.
The organism is isolated exclusively from humans and is found predominantly in the respiratory tract. catarrhalis adheres to mucosal cells with the aid of pili.
Infection is believed to result from contiguous spread of the organism from sites of colonization. Biochemistry. The lipopolysaccharide, that is an endotoxin, from M.

MODULE Bacterial Identification Tests Microbiology Notes 11 BACTERIAL IDENTIFICATION TESTS INTRODUCTION In the previous chapter we have discussed various methods of isolation of bacteria.
The bacteria thus isolated needs to be further identified to genus and species level. The identification is required so as to cure the illness or the.
Currently, presence of Moraxella sp. in internal organs of fish is not considered detrimental for fish farming. However, bacterial colonization of internal organs can affect fish wellness and decrease growth rate, stress resistance, and immune response.
Recently, there have been reports by farmers concerning slow growth, poor feed conversion, and low average weight increase of fish Cited by: Abstract. The Moraxella genus is comprised of two subgenera, Moraxella and Branhamella (Bøvre, ). Within the Moraxella subgenus are found six clearly delineated species: M.

The aim and scope of this book is to highlight the sources, isolation, characterization and applications of bioactive compounds from the marine environment and to discuss how marine bioactive compounds represent a major market application in food and other industries.
It discusses sustainable marine resources of macroalgal origin and gives examples of bioactive compounds isolated Reviews: 1. Non Technical Summary Moraxella bovoculi sp. nov is a novel species of Moraxella that has been isolated from eyes of calves with infectious bovine keratoconjunctivitis (IBK; 'pinkeye'); it is not known if M.
bovoculi sp. nov can actually cause IBK. This project examines whether M. bovoculi sp. nov when inoculated into the eyes of calves will induce IBK and therefore attempts to see whether.Phytochemical Analysis and Characterization Total Phenolic Content (TPC) and Total Flavonoid Content (TFC) Spirulina was considered a good source of nutritional phenolic and flavonoid compounds due to its higher production capacity compared to conventional plant-derived sources.
