Summary Escherichia coli has long been used as an indicator organism for water quality assessment. Recently there accumulation of evidence that suggests some strains this are able to proliferate in the environment, a characteristic would detract from its utility faecal pollution. Phenotypic and genotypic characterization E. isolated blooms two Australian lakes, separated by distance approximately 200 km, identified were dominated three strains. A major phenotypic similarity among bloom was...
Parasites from the Cryptosporidium genus are most common cause of waterborne disease around world. Successful management and prevention this emerging requires knowledge diversity species causing human their zoonotic sources. This study employed a spatiotemporal approach to investigate sporadic cryptosporidiosis in New South Wales, Australia, between January 2008 December 2010. Analysis 261 fecal samples showed that is caused by four species; C. hominis, parvum, andersoni, fayeri. Sequence...
ABSTRACT Gut microbiota play an important role in maintenance of mammalian metabolism and immune system regulation, disturbances to this community can have adverse impacts on animal health. To better understand the composition gut marine mammals, fecal bacterial communities Australian sea lion ( Neophoca cinerea ), endangered pinniped with localized distribution, were examined. A comparison samples from individuals across 11 wild colonies South Western Australia three captive populations...
This brief report reviews findings from a longitudinal study of skin-to-skin contact (SSC) with mothers and full-term infants follow-up these dyads when the children were 9 years. Findings infer positive influence SSC on mother-child interactions in infancy into children's middle childhood. Mothers control groups seen 1 week, month, 2 months, 3 months. group reported fewer depressive symptoms infants' early weeks had greater reduction salivary cortisol, physiological stress indicator, first...
Cryptosporidiosis is one of the most common waterborne diseases reported worldwide. Outbreaks this gastrointestinal disease, which caused by Cryptosporidium parasite, are often attributed to public swimming pools and municipal water supplies. Between months January April in 2009, New South Wales, Australia, experienced largest cryptosporidiosis outbreak Australia date. Through course contamination event, 1,141 individuals became infected with Cryptosporidium. Health authorities Wales...
The effect of maternal responsiveness on infants' emergence social bidding‐like behavior during the Still Face Task was examined longitudinally at infant ages one week, month, two months, and three months. Infants' behaviors smiling or making non‐distress vocalizations while looking mother still face phase significantly increased when infants were months age. These correlated with in initial interactive concurrent previous visits positive Regression analyses indicate that vocal visit sole...
ABSTRACT. The morphology and infectivity of the oocysts a new species Cryptosporidium from faeces red kangaroo ( Macropus rufus ) are described. Oocysts structurally indistinguishable those parvum . passed fully sporulated, lack sporocysts, measure 4.5–5.1 μm (mean=4.9) × 3.8–5.0 (mean=4.3 μm) with length to width ratio 1.02:1.18 (mean 1.14) n =50). were not infectious for neonate ARC Swiss mice. Multi‐locus analysis numerous unlinked loci demonstrated this be distinct (90.64%–97.88%...
The effects of skin-to-skin contact (SSC) on the maintenance mothers' decision to breastfeed, breastfeeding and SSC mother–infant interactions, whether maternal depressive symptoms mediate these were investigated over infants' first 3 months. When infants 1 week, month, 2 months, months age, mothers in control groups reported type infant feeding provided completed Edinburgh Postnatal Depression Scale (EPDS; J.L. Cox, J.M. Holden, & R. Sagovsky, 1987); interactions coded Nursing Child...
Management strategies associated with captive breeding of endangered species can establish opportunities for transfer pathogens and genetic elements between human animal microbiomes. The class 1 integron is a mobile element clinical antibiotic resistance in gram-negative bacteria. We examined the gut microbiota brush-tail rock wallabies Petrogale penicillata to determine if they carried integrons. No integrons were detected 65 animals from five wild populations. In contrast, 48% fecal...

Cryptosporidium macropodum n. sp is described. Oocysts of C. from the feces kangaroos (Macropus spp.) are morphologically indistinguishable other mammalian species, including parvum, hominis, suis, and canis. The oocysts fully sporulated on excretion, lack sporocysts, have an average width 4.9 microm (4.5-6.0), a length 5.4 (5.0-6.0), length:width ratio 1.1. Phylogenetic analyses 18S ribosomal RNA, actin, heat shock protein 70 (HSP70) loci demonstrate that genetically distinct all described...
The effects of maternal responsiveness on infant and behavior in the Still‐Face Task were longitudinally examined through infants' first 3 months. Maternal vocal smiling significantly increased when infants 2 months age. Mothers showed continuity individual differences from newborn period. predicted within across sessions. Compared with low‐responsive mothers, high‐responsive mothers more attentive affectively engaged during 1 month Infants discriminated between task phases their at month, a...
Greater interaction between humans and wildlife populations poses significant risks of anthropogenic impact to natural ecosystems, especially in the marine environment. Understanding spread microorganisms at interface is therefore important if we are mitigate adverse effects on wildlife. We investigated establishment Escherichia coli endangered Australian sea lion (Neophoca cinerea) by comparing fecal isolation from wild captive populations. Fecal samples were collected colonies March...
