Trypanosoma brucei: trypanocidal and cell swelling activities of lasalocid acid [PDF]
, 2017 Chemotherapeutic treatment of human and animal trypanosomaisis is unsatisfactory because only a few drugs are available. As these drugs have poor efficacy and cause adverse reactions, more effective and tolerable medications are needed.

Lasalocid in Prevention of Turkey Coccidiosis
Poultry Science, 1979 Lasalocid was tested at graded feed concentrations in controlled battery experiments against single and mixed Eimeria species infections in 2-week-old turykey poults. Eimeria meleagrimitis, E. gallopavonis, E. adenoeides, and E. dispersa infected poults medicated with lasalocid at concentrations of 0.15, .0125, .01, .0075, and .005% were heavier ...

The Journal of Antibiotics, 1974 Four isomeric homologs of lasalocid A have been isolated from cultures of Streptomyces lasaliensis. The homologs each arise by replacement of one of the four propionate derived methyls in lasalocid A by an ethyl group, which results in each homolog molecule containing four C-ethyls.

The Journal of Antibiotics, 1974 The biosynthesis of lasalocid A (formerly antibiotic X-537 A) in cultures of Strepto-myces lasaliensis has been studied using 13C- and 14C-labelled precursors. The antibiotic is derived from five acetate, four propionate and three butyrate units. This study has provided the first illustration of an ethyl group arising from butyrate and 2-ethylmalonate.

Effect of route of administration of lasalocid on response of young dairy calves [PDF]
, 1988 Forty newborn bull calves were assigned to one of four feeding groups. The feeds either contained lasalocid in milk (M), prestarter (PS), and starter (S); lasalocid in PS and S; lasalocid in S only; or no lasalocid.
