acidophiladj.n.

Brit.

/əˈsɪdəfɪl/, U.S.

/əˈsɪdəfɪl/

Forms: 1800s– acidophile, 1900s– acidophil.

Origin: Formed within English, by compounding. Etymons: acid n., -o- connective, -phile comb. form.

Etymology: < acid n. + -o- connective + -phile comb. form, after basophil adj. Compare scientific Latin acidophilus (see acidophilus adj.). With sense A. 2 compare earlier acidophilic adj. 2. Compare earlier acid-loving adj. at acid adj. and n. Compounds 1c.

A. adj.

1. Biology and Medicine. Of a cell or cellular component: staining readily with an acid dye; = acidophilic adj. 1. Cf. acidophilous adj. 1.Contrasted with basophil adj. and neutrophil adj. 1. Cf. oxyphil adj.

1895 Proc. Royal Soc. 59 71 They [sc. leucocytes] may be divided..into three main groups, the Hyaline, Acidophile, and Basophile.

1904 Science 23 Dec. 879/2 Cells with acidophile granules (eosinophiles).

1930 A. A. Maximow & W. Bloom Text-bk. Histol. v. 114 The protoplasm is purely acidophil, and stains a bright pink with the Romanowsky mixture.

1968 J. B. Jennings in M. Florkin & B. T. Scheer Chem. Zool. II. iii. ii. 308 A large proportion of the acidophile gland cells in the pharynx of Polycelis cornuta..secrete an active endopeptidase.

1998 N. Woolf Pathol. xl. 820/2 Growth hormone-producing tumours are usually acidophil in type.

2. Botany and Microbiology. In form acidophile. Of a plant, bacterium, etc.: growing well in an acidic environment. Cf. acidophilic adj. 2, acidophilous adj. 2.

1925 Jrnl. Hygiene 24 241 Organisms which are acid-tolerant, not acidophile, i.e., which..survive a concentration of acid lethal for B. coli, but which do not find at such a degree of acidity the optimum reaction for growth.

1993 R. L. Zimdahl Fund. Weed Sci. vi. 98 LeFevre..reviewed the pH tolerance of 60 weeds and grouped them into Basophile,..acidophile (love acid soil, e.g., red sorrel, corn marigold), and neutrophile.

B. n.

1. Biology and Medicine. A cell or cell component that can be readily stained with an acid dye.
