When udders were washed before milking, a post milking teat-dipping with a 5,000 mg available iodine/l iodophor induced an iodine residue of 33 to 54 micrograms l/kg in milk. The iodine contents of the first jets of milk were 1.08 to 8.27 times higher than those of average milk. However, the bulk of iodine residues in milk seemed to be an iodine transfer across teat skin to milk. From these dat...

In view of recent reports of contamination of the fibreoptic bronchoscope by tuberculous and non-tuberculous mycobacteria, we evaluated the disinfecting properties of aqueous glutaraldehyde (Cidex) and an iodophor (Prepodyne) against Mycobacterium tuberculosis and M gordonae. We found that a 15 minute disinfection procedure with either agent, coupled with initial vigorous mechanical cleaning of...

Efficacy of premiliking teat disinfection (predipping) with good udder preparation was compared with good udder preparation alone on four well-managed, commercial dairy farms. Three teat dip formulations containing iodophor were used for predipping. Predipping reduced the rate of intramammary infection with major mastitis pathogens approximately 54%. Infection rate with esculin-positive strepto...

MIC-tests in replicate were performed on 286 Salmonella isolates (269 from Danish poultry, including 256 from broiler houses, and 17 from England, mainly from poultry) against five disinfectants used in the poultry industry (glutaraldehyde/benzalkonium chloride compound, formaldehyde, oxidising compound, tar oil phenol, iodophor). Generally, the small variations in MIC could not be associated w...

To the Editor—We report that surgical site infections (SSIs) remain a major problem despite nearly a decade of national efforts to implement various practice-based recommendations targeting SSIs. According to a 2012 US Department of Health and Human Services news release, "Every day, approximately 1 in every 20 patients has an infection related to the patient's hospital care." SSIs exact a huge...

The sporicidal activity of hospital disinfectants was tested using two methods of test and two species of spores. Alcoholic hypochlorite and glutaraldehyde (Cidex) showed some sporicidal activity; the first was the more effective. Iodophors, formalin, and phenolics were less effective, in descending order. Chlorhexidine showed no activity.A freshly prepared solution containing 50% methanol and ...

Pseudomonas cepacia organisms were recently recovered from a povidone-iodine antiseptic solution. During the subsequent investigation, laboratory studies were initiated to determine the survival time of these organisms in the iodophor solution, which contains 1% titratable iodine. The solution was sampled weekly upon receipt in our laboratory, and P. cepacia was subsequently recovered through 2...

To the Editor: I would like to draw your attention to several points in "Brief Report: The Antiseptic Efficacy of Chlorxylenol-Containing vs. Chlorhexidine Gluco-nate-Containing Surgical Scrub Prep-arations" (Soulsby et al, Infect Control 1986; 7:223-226). In the discussion on page 2 2 5 , the a u t h o r s state that ".. . chlorhexidine gluconate-containing formulations are ineffective against...

The application of an established gloved-hand model to multiparameter measurements of skin-degerming activity is described. In particular, appropriate experimental designs are illustrated which allow characterization of performance of topical skin-cleansing preparations in terms of rapid, sustained, cummulative, and persistent skin-degerming effects on the hand. Single-contact studies were used...
