Restriction endonucleases are named in accordance with the proposals of Smith and Nathans (1973). Their names consist of a three letter abbreviation for the host organism (e.g. Eco for E. coli, Hin for Haemophilus influenzae. Bam for Bacillus amyloliquefaciens) followed by a strain designation and a Roman numeral. Thus Haemophilus influenzae, strain Rd contains at least three distinct restriction endonucleases and these are called Hindi, Hindll and Hindlll respectively. Restriction enzymes are generally known and described in the catalogues of suppliers by this code. 

Some recent reports on the presence of L-glycero-D-manno-heptose (46) include the LPS of Pseudomonas syringae pv. atrofaciens IMV 948240 and the LPS of nontypeable Haemophilus influenzae strain 486.241 The LPS of Helicobacter pylori contains, in the inner core, both L-g/ycero-D-manno-heptose (LD-Hep) and D-glycero-D-manno-heptose (DD-Hep, 45), 242...

There is a systematic way in which restriction enzymes are named (Smith and Nathans, 1973). The first three letters are in italics, and represent the genus and species names of the host bacterium. A nonitalicized letter may appear next, representing the particular strain from which the isolate was purified. The name will end with a roman numeral to indicate the order of discovery for multiple restriction enzymes arising from the same bacterium. For example, ficoRl was isolated from Escherichia coli RY13, while HindUl was isolated from Haemophilus influenzae strain d, and was the third enzyme isolated from this strain. (Note that the strain for HindUl can be found in older publications listed as Rd. The R is part of an R-M system, which denotes Restriction endonuclease versus Modification enzymes. The R and M strain designations are routinely dropped.)... 

Virus infections such as influenza and the common cold (in reality 300-400 different strains ofrhinovirus) infect epithelial cells ofthe respiratory tract and nasopharynx, respectively. Release ofthe virus, after lysis ofthe host cells, is to the void rather than to subepithelial tissues. The epithelia is further infected resulting in general degeneration ofthe tracts. Such damage predisposes the respiratory tract to infection with opportunistic pathogens such as Neisseria meningitidis and Haemophilus influenzae. 

Haemophilus influenzae is a bacterial respiratory pathogen that causes a wide spectrum of disease ranging from colonization of the airways to bacterial meningitis. It causes considerable morbidity and mortality, especially in children less than 5 years of age. H. influenzae is either encapsulated or unencapsulated. The encapsulated strains can be further differentiated into six antigenically distinct serotypes, a through f. H. influenzae type b was primarily found in cerebrospinal fluid and blood of children with meningitis, while the unencapsulated strains were found in the upper respiratory tract of adults. Before the introduction of the vaccine, H. influenzae was responsible for 20,000 to 25,000 cases of invasive disease annually and was the most common cause of bacterial meningitis. Since the introduction of the vaccine, invasive disease due to H. influenzae type b has been nearly eliminated.

Streptococcus pneumoniae is the most common cause of acute otitis media (20% to 35%). Nontypable strains of Haemophilus influenzae and Moraxella catarrhalis are each responsible for 20% to 30% and 20% of cases, respectively. In 44% of cases, a viral etiology is found with or without concomitant bacteria.
