Description:
A component of the ure gene cluster in E. coli, ureC, encodes a subunit of urease. We have investigated the distribution of ureC in 202 Shiga toxin-producing E. coli (STEC) strains from Austria belonging to 61 different serotypes. These strains were of human (n=150), animal (n=38), and food (n=14) origin. ureC was present in all 72 E. coli O157:H7 and O157:NM (non-motile) strains, as well as in all 29 strains of serotypes O26:H11/NM, O111:H8/NM and O145:NM. In contrast, none of eight sorbitol-fermenting E. coli O157:NM were ureC-positive. ureC occurred significantly more frequently among STEC that carry eae (113 of 132; 85.6%) than among eae-negative STEC strains (four of 70; 5.7%; p<0.0001). However, only 4 (2%) of the 202 strains (3.4% of ureC positive strains) expressed urease activity. There was no significant association (p=0.56) between urease expression and the source of the isolates (humans vs. animals). Nucleotide sequence analysis of PCR amplicons derived from all seven genes of the ure cluster in STEC of 10 different serotypes demonstrated a high degree of homology (>=99%), indicating a recent acquisition of not necessarily expressed ure genes. ...

Description:
Buruli ulcer (BU), an often-deforming skin ulceration caused by Mycobacterium ulcerans (MU), is now considered by the World Health Organization to be the third most common mycobacterium infection. However, the reservoir of MU in the environment and the epidemiology of BU are poorly understood. The disease is prevalent in riverine, slow-flowing and swampy areas of several tropical and subtropical regions of the world, especially in West Africa where the disease is rapidly increasing in incidence. This paper presents a review of published literature concerning epidemiology of, transmission and susceptibility to MU infection. It considers several endemic natural environments and their influence on infection. ... Read more

Description:
Blooms of the freshwater cyanobacterium Anabaena circinalis are recognised as an important health risk worldwide due to the production of a range of toxins such as saxitoxin (STX) and its derivatives, also known as paralytic shellfish poisoning (PSP) toxins. In this study the transcriptional profile of PSP toxin-producing and non-toxic strains of A. circinalis was investigated by means of a DNA microarray approach. Additionally, gene expression was studied after exposure of toxic A. circinalis cultures to lidocaine hydrochloride at 1 @mM for 2 h. Under standard growth conditions, a limited number of putative toxic-strain distinctive DNA fragments, identified in previous studies, were preferentially expressed in toxic versus non-toxic strains. The same genes did not significantly change their expression after exposure to 1 @mM lidocaine, conditions previously shown to induce STX production in the cyanobacterium Cylindrospermopsis raciborskii T3. Lidocaine supplementation, however, enhanced the transcription of genes involved in physiological adaptive responses and bloom formation in cyanobacteria, such as the gas vesicle structural protein A and phycocyanin. The heat shock protein HSP-70 and the chlorophyll-a binding protein isiA were significantly repressed by lidocaine exposure. Stress response proteins and genes implicated in secondary metabolism were repressed, including phosphopantetheinyl transferases. The BGGM^1 DNA microarray, used in this study, was shown to be suitable for gene expression studies in cultured toxic cyanobacteria and allowed the analysis of gene transcripts associated with surface scum formation by toxic A. circinalis. ...

Toxic Cyanobacteria in Water-from beginners to advanced
I would recomend this book to anyone looking for a comprehensive and easy to read text about toxic cyanobacteria.Chorus and Bartram have managed to fit together a great deal of very informative notes by many differentauthors in a format that progresses naturally from basic concepts ofcyanobacteria and their helpful/harmful effects to what can be done tomonitor, and manage them.Wheter you are just becoming interested incyanobacteria or lake health, or have been studying it for many years, thisbook should be part of your collection. The section on analytical methodsfor cyanobacteria provide excellent basic methodology in this area, butanyone wishing to undertake detailed analysis not from scratch would alsobe well off searching published methods in scientific journals as they willnot find all the nitty gritty details they will need.

A comprehensive and usefulbook on toxic cyanobacteria
This publication is useful to professionals dealing with problems related to Harmful Algal Blooms, including public health, water supply and management staff, since it discusses monitoring programmes and criteria fordifferent water uses (drinking water, recreational uses, organismsconsumption, haemodialysis), as well as a thorough discussion on remedialmeasures. It is essential to environment control officers, and because itwas published on behalf of the World Health Organization (WHO) it can beused as an official advice for countries lacking specific legislation onthe subject. It is useful as well for undergraduate and graduate studentsas its introduction and initial chapters present a summary on cyanobacteriaand its ecology (diversity, distribution, related environmental factors)and physiology. It then presents the different toxins produced by theseorganisms and their consequences to human health as well as a discussion onsafe levels and safe practices for each water use. This book discusses theimportance of this problem worldwide, through several case studies and wasproduced by a group of well known researchers from various continents. Someissues and events are discussed in several self-explained boxes within thepublication, which are intelligible and useful. The final chapters discussrisk management, monitoring programmes, field work, sampling and analyticalmethodology, including phytoplankton, clorophyll a and nutrients analysis,essential for those concerned with hazard identification and evaluation. This book is also interesting to everyone concerned with water quality andenvironmental issues, for cyanobacteria blooms are a widespread problemwhich results of excessive nutriet loads on water bodies, mostly because ofinadequate land use and inefficient water quality policies. Ultimately itsremediation depends on public awareness.

Description:
A survey of residents in an area subject to annual toxic cyanobacterial blooms was undertaken to examine potential health effects of cyanobacteria toxins. The survey assessed the health of marine recreational water users in Deception Bay/Bribie Island area in northern Moreton Bay, Queensland, which is exposed to blooms of the nuisance and potentially harmful cyanobacterium Lyngbya majuscula. A postal survey was mailed to 5000 residents with a response rate of 27%. High numbers of people (78%) responding to the survey reported recreational water activity in Moreton Bay. Of those having marine recreational water activity, 34% reported at least one symptom after exposure to marine waters, with skin itching the most reported (23%). Younger participants had greater water exposure and symptoms than older participants. Participants with greater exposures were more likely to have skin and eye symptoms than less exposed groups, suggesting agents in the marine environment may have contributed to these symptoms. Of those entering Moreton Bay waters 29 (2.7%) reported severe skin symptoms, 12 of whom attended a health professional. Six (0.6%) reported the classic symptoms of recreational water exposure to L. majuscula, severe skin symptoms in the inguinal region. Participants with knowledge of L. majuscula were less likely to report less skin, gastrointestinal and fever and headache symptoms. In conclusion, high numbers of participants reported symptoms after exposure to waters subject to L. majuscula blooms but only a small number appeared to be serious in nature suggesting limited exposure to toxins. ...

Product Description
Cyanobacteria, or blue-green algae, commonly occur in a variety of water types throughout the world. A variable but high proportion of the cyanobacterial blooms and scums, which can develop annually in lakes, reservoirs, canals and slow-flowing rivers contain potent toxins. Although animal poisonings and human health problems associated with the ingestion of, or contact with, cyanobacterial scums have long been recognised, a developing understanding of the health hazards posed by the toxins requires that reliable, sensitive, specific and convenient methods are available for their detection and quantification. Detection Methods for Cyanobacterial Toxins looks at the application of biological, toxicological, biochemical and physicochemical techniques in studies of cyanobacterial toxins and at experiments that have identified at least 50 cyanobacterial compounds toxic to vertebrates.Academics, public health bodies, environmental protection agencies and water companies are all involved in monitoring cyanobacterial levels and effects, and this book will help to ensure that their research is not duplicated, is standardised and comparable, and that optimal progress can be made in an important area that is still in its development stages. ...
