| colonization of the gastrointestinal tract of the farmed south african abalone haliotis midae by the probionts vibrio midae sy9, cryptococcus sp. ss1, and debaryomyces hansenii ay1. | viable cell counts and/or in situ hybridization were used to determine whether the probionts vibrio midae sy9, cryptococcus sp. ss1, and debaryomyces hansenii ay1 can colonize the gastrointestinal tract of the south african abalone haliotis midae. the number of culturable probiotic cells reisolated from h. midae fed probiotic-supplemented feed for 3 weeks ranged from 10(6) to 10(7) cfu/g gut material. a significant decrease (p < 0.05) in probiont numbers 2 days after feeding the probiotic-supple ... | 2006 | 16532366 |

| discovery and evaluation of single nucleotide polymorphisms (snps) for haliotis midae: a targeted est approach. | in this study, we describe the first set of snp markers for the south african abalone, haliotis midae. a cdna library was constructed from which ests were selected for the screening of snps. the observed frequency of snps in this species was estimated at one every 185 bp. when characterized in wild-caught abalone, the minor allele frequencies and f(st) estimates for every snp indicated that these markers may potentially be useful for population analysis, parentage assignment and linkage mapping ... | 2008 | 18454808 |
| identification and characterisation of the mpeg1 homologue in the south african abalone, haliotis midae. | although haliotis midae is the most economically important cultured abalone species in south africa, infectious diseases have the potential to severely limit the production of this shellfish. consequently, it is becoming increasingly important to characterise the abalone immune system in order to better understand their ability to combat infection. this study reports the identification and characterisation of a perforin-like protein, designated hmmpeg1, which is believed to be involved in the h. ... | 2011 | 21803160 |
| a 100,000-year-old ochre-processing workshop at blombos cave, south africa. | the conceptual ability to source, combine, and store substances that enhance technology or social practices represents a benchmark in the evolution of complex human cognition. excavations in 2008 at blombos cave, south africa, revealed a processing workshop where a liquefied ochre-rich mixture was produced and stored in two haliotis midae (abalone) shells 100,000 years ago. ochre, bone, charcoal, grindstones, and hammerstones form a composite part of this production toolkit. the application of t ... | 2011 | 21998386 |
| domain repeats related to innate immunity in the south african abalone, haliotis midae. | molluscs predominately use the cellular defence system as the primary mechanism of defence against pathogenic infection, in which haemocytes play a pivotal role. haliotis midae is a commercially important south african species that it is susceptible to bacterial pathogens, fungal and yeast infections in the farming environment. the current study aims to enrich the current knowledge regarding h. midae innate immunity by investigating the presence and evolution of domain repeats. the bioinformatic ... | 2015 | 25936498 |
| detection and localisation of the abalone probiotic vibrio midae sy9 and its extracellular protease, vmproa, within the digestive tract of the south african abalone, haliotis midae. | probiotics have been widely reported to increase the growth rate of commercially important fish and shellfish by enhancing the digestion of ingested feed through the production of extracellular enzymes such as proteases and alginases. in order to investigate this further, the objective of this study was to localise the bacterial probiont vibrio midae sy9 and one of the extracellular proteases it produces in the digestive tract of the south african abalone haliotis midae. this was accomplished by ... | 2014 | 24466176 |
