An additional method for differentiating between Campylobacter fetus subsp. jejuni and C. fetus subsp. intestinalis is reported. Strains of C. fetus subsp. jejuni (18/20) were shown to hydrolyze hippurate in the 2-h rapid test, whereas strains of C. fetus subsp. intestinalis did not.

Presently, the two most commonly used drugs for treating microsporidiosis in persons with AIDS are albendazole and fumagillin. Albendazole is effective for treating disseminated infections due to Encephalitozoon spp. but is variably effective against Enterocytozoon bieneusi infections. Fumagillin is highly effective when used topically to treat ocular infections with Encephalitozoon hellem or E...

Giardia intestinalis, a cosmopolitan zoonotic parasite, is one of the most common causes of protozoal diarrhea in both humans and animals worldwide. Although G. intestinalis has been detected in many animals, information regarding its prevalence and genotype in Chinese racehorses is scarce. In the present study, we investigated the prevalence of G. intestinalis in racehorses and performed molec...

Anti-inflammatory drugs presently available for the treatment of various inflammatory disorders have diverse and undesirable side effects. In recent years; active principles of varied chemical structures have been isolated from plants possessing anti-inflammatory activity. Sulfated polysaccharides present in algae were shown to posses anti-inflammatory properties. Ulva lactuca the green alga av...

Since fouling-release coating systems do not prevent settlement, various methods to quantify the tenacity of adhesion of fouling organisms on these systems have been offered. One such method is the turbulent channel flow apparatus. The question remains how the results from laboratory scale tests relate to the self-cleaning of a ship coated with a fouling-release surface. This paper relates the ...

In this paper we report on the effect of surface wettability on surface selection and adhesion properties of settled (adhered) spores of the biofouling marine alga Enteromorpha and cells of the diatom Amphora, through the use of patterned self-assembled monolayers (SAMs). The SAMs were formed from alkanethiols terminated with methyl (CH(3)) or hydroxyl (OH) groups, or mixtures of the two, creat...

Food choice is known to be correlated with genotype in the crustacean Gammarus palustris. Given a choice of Enteromorpha intestinalis (E) over Ulva lactuca (U), individuals homozygous for the Amy II.52 allele have a greater preference for E than do Amy II.55 homozygotes. To account for this correlation, we hypothesized that the proportions of saccharides released by the enzymatic action of Amy ...

Marine algae are easily produced and are good sources of Fe. If this Fe is bioavailable, algae consumption could help to combat Fe deficiency and anaemia worldwide. The objective of the present study was to evaluate Fe bioavailability, polyphenol content and antioxidant capacity from three species of marine algae distributed worldwide. A total of eighty-three subjects received maize- or wheat-b...
