Development and application of genomic tools for characterising genetic variation in soil-transmitted helminths
… and identification of eggs or larvae in faecal samples. However, these techniques can be labour-intensive, and their diagnostic performance and sensitivity rely heavily on sample preparation and the prevalence of infections. Molecular tests, such as quantitative polymerase chain reactions …

Die ondersoek na spesifieke bakteriegroepe in die feses van geselekteerde proefpersone
… in the human gastrointestinal tract. Eight faecal samples were examined for the presence of the following bacteria, viz ., lactobacilli, methane producing- and sulphate reducing bacteria. Total aerobic and anaerobic counts as well as the number of enterobacteria were determined. These …

Effectiveness of visceral osteopathic treatment on gastrointestinal indicators and behaviour patterns in autistic children: using questionnaire and biochemical markers to measure outcomes
… study aimed to evaluate inflammatory markers in faecal samples taken from autistic children with GI dysfunction before, during and after visceral osteopathic techniques (VOT), and to link these findings with contemporaneous questionnaires. These data assessed whether GI status could be reliably …

Prevelance of Avian Influenza Viruses in Northern Zambia
… and domestic ducks. Cloacal, tracheal swabs and faecal samples were examined in the Biosafety level-3 laboratory in the School of Veterinary Medicine at the University of Zambia. A total of 294 paired cloacal and 294 paired tracheal swabs were collected from hunted wild migratory waterfowl around …

Should I stay or should I go? Hormonal and demographic correlates of natal dispersal in a population of wild vervet monkeys
… to the difficulties of obtaining sufficient faecal samples of the same individuals before, during and after a successful dispersal. In this study, I aimed to better understand the hormonal correlates (i.e. testosterone and cortisol) of dispersal in free ranging, habituated male vervets …

Ταχεία ανίχνευση της εντεροτοξίνης του C. perfringens τύπου Α με την ανοσοενζυμική μέθοδο ELISA, σε κόπρανα ασθενών με συμπτώματα τροφικής δηλητηρίασης
… assay (ELISA) for tracing of the enterotoxin in faecal samples was considered to be essential. In the present study an effort was made to detect the presence of enterotoxin of C. perfringens in stools. 280 faecal samples taken from patients with symptoms of food poisoning suspected to be caused …

Gastrointestinal parasite infections in Chacma baboons (Papio ursinus) of the Cape Peninsula, South Africa : the influence of individual, group and anthropogenic factors
… diversity and prevalence were obtained from 616 faecal samples collected from over 350 individuals in eight troops (six from the Cape Peninsula, one from Pringle Bay, and one from Wildcliff Nature Reserve) between July 2006 and August 2007.

Potential of faeces for non-invasive assessment of Juan Fernandez fur seals and their environment
… of the JFFS, I explored the potential of faecal samples as a non-invasive method to obtain diverse information while lowering sampling cost and logistic complexities. Here, I focused on only three of the multiple topics that can be studied from faecal samples. First, I used 16S rRNA …

Characterisation and public health significance of selected enteropathogenic bacteria isloated from Japanese quails(Cortunix cortunix japonica) in Lusaka, Zambia
… indicate that Salmonella was absent from the faecal samples collected however other bacteria of public health significance such as Proteus and E. coli were isolated. From the E. coli species isolated, six isolates were identified and shown to have resistant genes CTX-M. Extended Spectrum …

Genetic variation and parentage in the Ethiopian wolf Canis simensis
… (microsatellite genotyping) based on existing faecal samples collected between 2007 and 2010 to (i) determine the standing amount of genetic variation after recent rabies outbreaks, (ii) reveal the family structure within and between packs using genetic parentage analysis, comparing the …

The ecology of venom use in the Javan Slow Loris (Nycticebus Javanicus) and its implications for conservation
… including feeding and ranging data, examined faecal samples for diet remains and parasites, and regularly checked animals for ectoparasites. I also captured arthropods over five months. I monitored the coexistence with potential predator species using camera traps and by conducting forest …

Interactions between salmonella typhimurium and human gut bacteria
… after infection. In this study the effect of faecal bacteria on the growth and survival of S. Typhimurium was investigated. Initially, experiments involved co-cultures of the pathogen and single strains of intestinal bacteria obtained from culture collections; results showed that when E. coli …

Phylogeny and phylogeography of the Chacma Baboon (Papio ursinus): the role of landscape in shaping contemporary genetic structure in the southern African baboon
… the hypervariable D-loop. DNA was extracted from faecal samples of 261 free living chacma baboons across southern Africa. Phylogenetic and phylogeographic techniques, including coalescent modeling, were used to examine past and present population dynamics of chacma baboon populations. Bayesian …

Novel insights into fibre and lipid substrates on the microbiome
… and assessing pathogen growth following 24-hour faecal fermentation. Glucose was used as a positive control to compare the success of pathogen growth in the presence of various pre-digested dietary fibres. Pathogen abundance was evaluated by 16S rDNA sequencing, qPCR and the effects on metabolic …
