Chemical symbols may be used for elements, groups and simple compounds, but
excessive use should be avoided. Abbreviations other than the above should not be
used in titles.
Bacterial nomenclature. Organisms should be referred to by their scientific
names according to the binomial system. When first mentioned the name should be
spelt in full and underlined to denote italics. Afterwards the genus should be
abbreviated to its initial letter, e.g. 'S. aureus' not 'Staph. aureus'. If abbreviation is
likely to cause confusion or render the intended meaning unclear the names of
microbes should be spelt in full. Only those names which were included in the
Approved List of Bacterial Names, Int J Syst Bacteriol 1980; 30: 225?420 and those
which have been validly published in the Int J Syst Bacteriol since 1 January 1980
have standing in nomenclature. If there is good reason to use a name that does not
have standing in nomenclature, the names should be enclosed in quotation marks
and an appropriate statement concerning the nomenclatural status of the name
should be made in the text (for an example see Int J Syst Bacteriol 1980; 30:
547?556). When the genus alone is used as a noun or adjective, use lower case
roman not underlined, e.g.'organisms were staphylococci' and 'streptococcal
infection'. If the genus is specifically referred to underline e.g. 'organisms of the
genus Staphylococcus'. For genus in plural, use lower case roman e.g.
'salmonellae'; plurals may be anglicized e.g.'salmonellas'. For trivial names, use
lower case roman e.g. 'meningococcus'.
Numbers, measurements and statistics. Numbers one to nine are spelled
unless they aremeasurements (e.g.5mL). Numbers greater than nine are spelled
out if they begin in a sentence, or when clarity requires it. Numbers above and
including 10 000 have a space, not a comma. A decimal point is preceded by a
number or cypher e.g. '0.5'.Decimal points in columns should be aligned vertically.
Dates are usually provided in full: 14 April 1949. Measurements may be expressed
in SI or non-metric units. Use 10 ml/h rather than -1 or per.
Abbreviations. Use capitals for: MIC, MBC, WBC, RBC, DNA, RNA, Group A, B etc.
for antigenic or other groups, PHLS, CDSC, CDC, WHO, CSF, MSU, EMU, CSU. Use
cfu, pfu, mm, m, min, h, in, ft, g, kg, mL, L, im, iv, iu, P(probability). Use sp. and
spp. (species, singular and plural). Use Gram's stain and Gram-negative bacillus.
Use in-vitro (adjective) but in vitro (adverb), post-mortem (adjective) but post
mortem (adverb). Spelling. Use British spellings: Haemophilus, haematology,
