The phylogenetic relationships of all species in the genus Campylobacter, Wolinella succinogenes, and other gram-negative bacteria were determined by comparison of partial 16S ribosomal ribonucleic acid sequences. The results of this study indicate that species now recognized in the genus Campylobacter make up three separate ribosomal ribonucleic acid sequence homology groups. Homology group I contains the following true Campylobacter species: Campylobacter fetus (type species), Campylobacter coli, Campylobacter jejuni, Campylobacter laridis, Campylobacter hyointestinalis, Campylobacter concisus, Campylobacter mucosalis, Campylobacter sputorum, and

A survey of the isolation rate and population size of thermophilic campylobacters in lambs at slaughter was carried out to determine the seasonal variation of thermophilic campylobacters in ovine hosts. Isolation rates determined by enrichment methods were always higher than those using direct plating onto selective agar and showed that Campylobacter could be isolated from 91·7% (n = 360) of samples from the small intestine of the lambs. Enumerations (MPN), done monthly over a 2-year period, averaged 4·00 log 10 (n = 1080, S.D. 0·16) campylobacters g−1 fresh weight (fw) intestinal contents with some samples giving values higher than 7 log MPN gfw−1. These results show that the prevalence of thermophilic campylobacters in sheep intended for slaughter is much higher than previously reported. Statistical analyses showed that there was a significant seasonal periodicity in the Campylobacter populations in the small intestines of lambs at slaughter (P = 0·004) but that there was no ...
Campylobacter lanienae is a species of Campylobacter found in humans and other animals. Like other Campylobacter species, it is rod-shaped, non-glucose-fermenting, oxidase- and catalase-positive, Gram-negative and motile. Logan, J.; Burnens, A.; Linton, D.; Lawson, A. J.; Stanley, J.

From 1979 to 1996, 58 patients (mean age, 39.4 years) were treated for bacteremia due to Campylobacter species at the Hospitals Vall dHebron in Barcelona, Spain. Bacteremia was considered to be hospital acquired in 30% of these patients. Almost all the patients (93%) had underlying conditions; liver cirrhosis was the most frequent (34% of patients), and neoplasia, immunosuppressive therapy, and human immunodeficiency virus disease were also common. Of the 58 Campylobacter strains isolated, 81% were C. jejuni, 10% were Campylobacter species, 7% were C. fetus, and one (2%) was C. coli. Resistance rates were: cephalothin, 82%; co-trimoxazole, 79%; quinolones, 54%; ampicillin, 20%; amoxicillin/clavulanate, 4%; erythromycin, 7%; gentamicin, 0; and tetracyclines, 0. Even though the majority of patients were immunocompromised, mortality was low (10.5%), and only one patient relapsed. Because of the high level of resistance to the quinolones in Campylobacter species, these drugs should not be used as ...
Infections with Campylobacter spp. pose a significant health burden worldwide. The significance of Campylobacter jejuni/Campylobacter coli infection is well appreciated but the contribution of non-C. jejuni/C. coli spp. to human gastroenteritis is largely unknown. In this study, we employed a two-tiered molecular study on 7194 patient faecal samples received by the Microbiology Department in Cork University Hospital during 2009. The first step, using EntericBio® (Serosep), a multiplex PCR system, detected Campylobacter to the genus level. The second step, utilizing Campylobacter species-specific PCR identified to the species level. A total of 340 samples were confirmed as Campylobacter genus positive, 329 of which were identified to species level with 33 samples containing mixed Campylobacter infections. Campylobacter jejuni, present in 72.4% of samples, was the most common species detected, however, 27.4% of patient samples contained non-C. jejuni/C. coli spp.; Campylobacter fetus (2.4%),

Poultry represent an important source of foodborne enteropathogens, in particular thermophilic Campylobacter species. Many of these organisms colonize the intestinal tract of broiler chickens as harmless commensals, and therefore, often remain undetected prior to slaughter. The exact reasons for the lack of clinical disease are unknown, but analysis of the gastrointestinal microbiota of broiler chickens may improve our understanding of the microbial interactions with the host. In this study, the fecal microbiota of 31 market-age (56-day old) broiler chickens, from two different farms, was analyzed using high throughput sequencing. The samples were then screened for two emerging human pathogens, Campylobacter concisus and Helicobacter pullorum, using species-specific PCR. The gastrointestinal microbiota of chickens was classified into four potential enterotypes, similar to that of humans, where three enterotypes have been identified. The results indicated that variations between farms may have
Campylobacter species are recognized as the most common cause of foodborne bacterial gastroenteritis in humans. In this study nine Campylobacter strains isolated from chicken meat and pork in Hanoi, Vietnam, were characterized using molecular methods and tested for antibiotic resistance. The nine isolates (eight C. jejuni and one C. coli) were identified by multiplex PCR, and tested for the presence or absence of 29 gene loci associated with virulence, lipooligosaccharide (LOS) biosynthesis and further functions. flaA typing, multilocus sequence typing and microarray assay investigation showed a high degree of genetic diversity among these isolates. In all isolates motility genes (flaA, flaB, flhA, fliM), colonization associated genes (cadF, docB), toxin production genes (cdtA, cdtB, secD, secF), and the LOS biosynthesis gene pglB were detected. Eight gene loci (fliY, virB11, Cje1278, Cj1434c, Cj1138, Cj1438c, Cj1440c, Cj1136) could not be detected by PCR. A differing
EN] Campylobacter is the most common bacterial cause of human gastrointestinal disease in most developed countries. It is generally accepted that poultry products are a significant source of foodborne Campylobacter infections in humans. Assessing the effectiveness of any potential intervention at farm level requires monitoring of the Campylobacter status of broiler flocks, using appropriate sampling methods. The aim of this study was to assess the influence of the sample type across the rearing period for the detection of Campylobacter spp. at farm level. During this study, 21 commercial broiler farms were intensively sampled. Each farm was visited and sampled at different times during the rearing period (d 1, 7, 14, 21, 28, 35, and 42). On the first day of rearing, the status of the house and the day-old flock was evaluated, and environmental and cecal samples were collected. During rearing, 4 different sample types were collected: feces with sock swabs (sock swabs), feces directly from the ...
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significance was tested by Fishers test (p,0.05). A Campylobacter prevalence of 81.8% was found in the broiler flocks (18/22), and within positive flocks, it varied between 85 and 100%. Campylobacter incidence among sample types was homogenous, being 81.8% in cecal droppings, 80.9% in feces, and 80.4% in cloacal swabs (230). Flocks fed by automatic feeding systems presented higher incidence of Campylobacter as compared to those fed by tube feeders. Litter was reused in 63.6% of the farm, and, despite the lack of statistical significance, there was higher likelihood of Campylobacter incidence when litter was ...
To identify epidemiological features of culture-proven campylobacter infections and to determine resistance rates, we conducted a 4-year demographic survey of culture-proven campylobacteriosis in one Dutch region. Examination of 24,435 fecal specimens revealed 1,315 cases of campylobacteriosis (5.4%). The ofloxacin-resistance rate among Campylobacter isolates increased from 11% to 29%. Resistance against tetracycline fluctuated between 7% and 15%, and resistance against erythromycin remained low. Resistance against fluoroquinolones was seasonally influenced, with relatively high rates during winter. We conclude that resistance of Campylobacter isolates to fluoroquinolones is still rising, probably because of the use of fluoroquinolones (enrofloxacin) in animal husbandry.. ...
Resistance to antimicrobial agents used to treat severe Campylobacter spp. gastroenteritis is increasing worldwide. We assessed the antimicrobial resistance patterns of Campylobacter spp. isolates of human and animal origin. More than half (n = 32) were resistant to sulphonamide, a feature known to be associated with the presence of integrons. Analysis of these integrons will further our understanding of Campylobacter spp. epidemiology.
Summary Broth-culture filtrates of Campylobacter pylori induced non-lethal cytopathic effects in vitro in 7 of 9 mammalian cell lines tested. Transmission electronmicroscopy revealed that the response consisted of intracellular vacuolisation. Intestine 407 cells were among the most responsive and were used for routine assay. About 55% of isolates of C. pylori tested, originating from four geographic regions worldwide, produced cytotoxic activity. The activity was neutralisable by specific antisera to broth-culture filtrates or to sonicated bacteria but not by antisera to other bacterial preparations. Cytotoxic activity was heat-labile (70°C for 30 min), was protease-sensitive and ammonium-sulphate precipitable. It did not pass through an ultrafiltration membrane with a nominal mol.-wt limit of 100 x 103. It was concluded that C. pylori can produce a factor that alters cultured cells in vitro. The relevance of this factor to the pathogenesis of gastritis associated with C. pylori remains to be

Introduction. Campylobacter is one of most common causative agents of bacterial food and waterborne illness in humans (Sheppard et al., 2009) and is responsible for an estimated 2.4 million cases of human illness per year in the US alone (Thomas et al., 1999; Center for Disease Control and Prevention, (CDC), National Center for Emerging Zoonotic and Infectious Diseases, 2010). Campylobacter is a gram negative, non-spore forming, rod-shaped bacterium and the genus is comprised of at least 17 species. Most Campylobacter species are microaerophilic, and most pathogenic species require thermophilic conditions for growth. The most common species affecting humans is C. jejuni. However, among several other species, C. coli,C. lariand C. ureolyticus have also been implicated in human infection (Thomas et al., 1999; Allos, 2001; Koziel et al., 2012). Poultry are considered a major source of human infection; however, other livestock such as cattle, sheep and pigs have also been identified as potential ...

Campylobacter (kamp-pi-lo-BAK-ter) is a type of bacteria that is a normal inhabitant of the digestive tract of many animals. People, however, do not normally carry Campylobacter, and exposure to it usually causes an intestinal infection called campylobacteriosis (kamp-pi-lo-bak-ter-ee-O-sis). The most common source of Campylobacter in the United States is chicken. When chickens (and other animals) are killed for food, the bacteria from their digestive tract can contaminate the meat. People get infected when they eat raw or uncooked meats and eggs (thorough cooking kills the bacteria), drink raw (unpasteurized) milk, or drink contaminated water. Oftentimes, juices from raw meats drip and contaminate other foods. In rare cases, contact with people or animals who are infected spreads the illness. Campylobacter is the most common bacterial cause of diarrhea in the United States, where more than 2 million cases occur each year. The illness most frequently affects infants and children younger than age ...
Dr. Taylors research on Campylobacter species, particularly antibiotic resistance, DNA transformation and vector construction, have advanced Campylobacter genetics and enabled others using techniques developed in her laboratory, to make major contributions to understanding Campylobacter pathogenesis. Dr. Taylor was the first to demonstrate that Campylobacter jejuni and Campylobacter coli harbored tetracycline resistance (TcR) plasmids, which were transmissible only within the Campylobacter species, but not to other species such as Escherichia coli. She has spent the past 30 years investigating the novel mechanism of TcR, initially identified on Campylobacter plasmids and called Tet(O) but now recognized as an extremely common cause of TcR. Her group coined the term ribosomal protection for this mode of resistance, determined its gene sequence and similarity to translocation factors EF-G and EF-Tu. Recently her group showed that the Tet(O) protein modifies the ribosome by changing its ...
Summary The pathogenesis of campylobacter enteritis is not well understood, but invasion into and translocation across intestinal epithelial cells may be involved in the disease process, as demonstrated for a number of other enteric pathogens. However, the mechanisms involved in these processes are not clearly defined for campylobacters. In this study, isolates were compared quantitatively in established assays with the enterocyte-like cell line, Caco-2, to determine the extent to which intracellular invasion contributes to translocation across epithelial cell monolayers, and whether isolates vary in this respect. Ten fresh Campylobacter isolates were compared and shown to differ in invasiveness by a factor of 10-fold by following their recovery from gentamicin-treated Caco-2 cells grown on non-permeable tissue-culture wells. Four of these isolates with contrasting invasive ability were also shown to vary in their ability to translocate across Caco-2 cells grown on semi-permeable Transwell inserts by a

To study whether broiler and layer farms contribute to the environmental Campylobacter load, environmental matrices at or close to farms, and caecal material from chickens, were examined. Similarity between Campylobacter from poultry and environment was tested based on species identification and Multilocus Sequence Typing. Campylobacter prevalence in caecal samples was 97% at layer farms (n = 5), and 93% at broiler farms with Campylobacter-positive flocks (n = 2/3). Campylobacter prevalence in environmental samples was 24% at layer farms, and 29% at broiler farms with Campylobacter-positive flocks. Campylobacter was detected in soil and surface water, not in dust and flies. Campylobacter prevalence in adjacent and remote surface waters was not significantly (P , 0.1) different. Detected species were C. coli (52%), C. jejuni (40%) and C. lari (7%) in layers, and C. jejuni (100%) in broilers. Identical sequence types (STs) were detected in caecal material and soil. A deviating species distribution ...
Campylobacter is common in birds. Migratory birds result in large seasonal changes in the inputs to the environment from bird feces and could contribute to human Campylobacter exposure (55). Migratory birds could be a seasonally changing driver to human disease (56). The main likely exposure route if this were the case would be direct contact with contaminated bird feces in the garden, contamination of field-grown fruit and vegetables and contamination of source waters for drinking. Bird-pecked milk is a recognized route by which Campylobacter infection can be acquired (53,54). The contamination is thought to result from birds feeding consecutively on cow feces and milk in bottles. The infections related to bird-pecked milk appear to be seasonal in distribution with a marked increase in May (57 ...
Routine detection of Campylobacter typically involves a 48 hour cultivation by selective enrichment under specific growth conditions, followed by detection using selective agar plating (requiring a further 48 hours of incubation followed by confirmation testing). At present, there are no rapid and sensitive in situ Campylobacter tests available. The use of a lateral flow device (LFD) can significantly reduce the result time but LFDs do not have sufficient sensitivity to be used for environmental detection without preliminary (48 hour) enrichment. This is therefore not suitable as a rapid in situ test. Campylobacter can also be detected using PCR-based methods but requires that the sample undergoes extensive preparation to extract the DNA and remove the environmental contaminants that interfere with the PCR reactions. Further, should the amplicon (part of the DNA that is detected and is amplified as part of the process) escape into the environment, the area becomes contaminated, giving false ...

A number of investigators in a variety of countries have compared these two serotyping protocols in terms of the strengths and advantages of each and what they have achieved since their introduction; however, it is difficult to compare O antigen typing results to those of HL antigen typing given that each scheme is used to detect different antigens on the bacterium. In 1985, Patton et al. (21) performed a comparative study using the Penner and Lior methods for serotyping Campylobacter. Their findings indicated that 96.1% of isolates were typeable by the Penner method and that 92.1% were typeable by the Lior method. In 1993, a second study by the same group determined that, of a representative sample of 298 Campylobacter isolates from across the United States, a total of 24 O antisera were needed to serotype 84.6% of the strains by the HS scheme (20). Among the most common serotypes were O:1 (or O:1,8), O:13,16,43,50, O:8 (or O:8,17), O:4, O:5−,5+, O:2, O:3, O:6,7,25,29, O:19, and O:15,38. One ...

pathogen is C. jejuni, which accounts for 80-90% of all cases of recognized illness due to campylobacters and related genera. Other organisms that cause diarrheal disease include C. coli, C. upsaliensis, C. lari, C. hyointestinalis, C. fetus, A. butzleri, A. cryaerophilus, H. cinaedi, and H. fennelliae. The two Helicobacter species causing diarrheal disease, H. cinaedi and H. fennelliae, are intestinal rather than gastric organisms; in terms of the clinical features of the illnesses they cause, these species most closely resemble Campylobacter rather than H. pylori (Chap. 151) and thus are considered in this chapter. ...
Campylobacteriosis is an illness that is caused by the bacteria of the genus Campylobacter. Most of the disease is caused by the species called campylobacter jejuni. The symptoms of this disease is diarrhea, cramps and fever within 2-5 days of infection. The diarrhea can be bloody with nausea and vomiting. This bacteria is gram negative and has a spiral shape. This disease is one of the most common cause of diarrheal outbreaks in Indonesia though it usually do not cause death and seldom reported. The most commonly reported cases of campylobacteriosis are associated with the eating of raw meat or under cooked meat or from cross contamination of other foods from these items ...
Salmonella, Campylobacter, and Eschericia coli O157:H7 are important foodborne pathogens, but longitudinal studies of their prevalence in beef cattle feedyards have not been done. Our long- term study involved 24,556 samples taken from beef cattle feedyards found overall prevalences of 4.87% for Salmonella, 20.1% for Campylobacter in hospital pen fecal samples, and 0.20% for E. coli O157:H7. Yard and pen differences (P,0.05) were detected. All 53 E. coli O157:H7 isolates were resistant to Talmicosin and Erythromycin, two antimicrobials used in food animal medicine. Their genetic diversity was high and did not indicate the presence of resident strains at the yards studied. Salmonella, Campylobacter, and E. coli O157:H7 were probably brought into the yards by shipments of new cattle. Many of these organismswere susceptible to antibiotics commonly used to treat beef cattle ...
Campylobacter species are the commonest cause of food poisoning in man, affecting over 50,000 people in the UK and 69/100,000 population in Denmark each year, but Danish researchers have shown that potentially, only a small fraction of pig isolates are associated with man and these strains are also found in poultry, which appears to be a major source.

Campylobacter can cause a gastrointestinal infection called campylobacteriosis. The incubation period is 24-72 hours after infection.[22] This is characterized by inflammatory, sometimes bloody diarrhea or dysentery syndrome, mostly including cramps, fever, and pain.[23][24] The most common routes of transmission are fecal-oral, ingestion of contaminated food or water, and the eating of raw meat. Foods implicated in campylobacteriosis include raw or under-cooked poultry, raw dairy products, and contaminated produce.[25] Campylobacter is sensitive to the stomachs normal production of hydrochloric acid: as a result, the infectious dose is relatively high, and the bacteria rarely cause illness when a person is exposed to less than 10,000 organisms.[3] Nevertheless, people taking antacid medication (e. g. people with gastritis or stomach ulcers) are at higher risk of contracting disease from a smaller amount of organisms, since this type of medication inhibits normal gastric acid. The sites of ...

Campylobacter is one of the common causes of foodborne bacterial infection in the developed world. In the US the incidence of foodborne Campylobacter infection are estimated to be more than 2 million, resulting in more than 10,000 hospitalization and treatment cost exceeding 1.7 million (Mead et al., 1999). Many of these cases are believed to be due to unsafe food handling. This study encompasses three major aspects; preharvest, processing and postharvest and investigates possible sources of contamination from farm-to-table. ...

Campylobacter infections in humans have increased considerably in the past ten years. Since the beginning of Campylobacter history poultry has been considered to be an important cause of infection in humans. Good co-operation is essential in working towards effective methods to cope with the problems.
PulseNet USA is a network of public health laboratories from all 50 states, federal food regulatory agency laboratories, and a few state agricultural laboratories in the United States dedicated to molecular surveillance of food-borne bacterial infections. Regional and national PulseNet networks inspired by PulseNet USA have been established in different parts of the world dedicated to molecular surveillance of food-borne infections. PulseNets work together in investigations of international outbreaks in building capacity for molecular surveillance all over the world and in the development and validation of new PulseNet methods to ensure that data generated in all participating networks are comparable. As Campylobacter species are a common cause of diarrheal illness, active case finding during an outbreak can inevitably turn up additional Campylobacter infections that may or may not be related to the outbreak. Multilocus sequencing typing (MLST) has recently emerged as the current method of choice for
Campylobacter is part of the natural gut microflora in chickens, turkeys, swine, cattle and sheep. It only takes 500 Campylobacter cells to cause infections in humans, making it an important pathogen test for food manufacturers.

Campylobacters are spiral-shaped bacteria that often colonize the intestines of animals grown for food (as well as other animals)-and they can cause acute diarrheal disease (called campylobacteriosis) in humans.
Campylobacter is considered to be one of the major pathogens responsible for food poisoning that occurs particularly after consuming the incorrectly stored or improperly thermally treated poultry meat. Thus, research studies are intensified that are targeted at searching for disinfection techniques, which are environmentally safe and effectively eliminate that pathogen. The Department of Food Quality at the Institute of Agricultural and Food Biotechnology in Łódź undertook research the objective of which was to determine the effectiveness of environmentally friendly disinfection with the use of ozone and ultraviolet irradiation to inactivate Campylobacter sp. inoculated on agar plates, and, then, in poultry meat. It was proved that the two disinfecting agents caused the counts of Campylobacter spp. to decrease. When applying the method with agar plates, the reduction degree of bacteria was above 2 log cfu /ml regardless of the strain and sanitising agent. After 30 minutes of sterilizing the ...
Campylobacteriosis is an infection by the campylobacter bacterium, most commonly c. It is among the most common bacterial infections of humans, often a foodborne illness.
The past 10-15 years has seen an almost unprecedented interest in the pathogenic ability of Helicobacter pylori. This is perhaps because it is the main cause of gastritis, responsible for up to 80% of gastric and 95% of duodenal ulcers,1 and is implicated in the pathogenesis of gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma.2 The importance of this bacterium was not appreciated until 1983, although it had been recognised in the gastric mucosa nearly a century ago. Initially research concentrated on classification, in vitro culture, and histopathology. The bacterium was first called Campylobacter pyloridis, but was subsequently differentiated from campylobacter by, among other properties, the presence of multiple flagellae. A new genus (helicobacter) was devised in 1989. Since then many different strains have been identified with variable virulence-for example, those carrying the cagA gene cause a greater gastric inflammatory response.. However, the gastroenterology ...
Among all brands and types of broilers tested, 68 percent of the salmonella and 60 percent of the campylobacter organisms analyzed showed resistance to one or more antibiotics. All of the antibiotics were effective against 32 percent of salmonella samples and 40 percent of the campylobacter samples, as compared to just 16 and 33 percent in 2007.. USDA recently released a survey [PDF] testing these same pathogens in chicken, and reported finding much lower numbers. The method CR used for campylobacter presence is one of two methods cited in the USDA study and the method used for salmonella presence in the USDA study is the same used by CR. The difference is that CR obtained its samples at retail stores while the USDA samples were obtained at two points in the processing plant.. According to CR, there is more likelihood that chicken can be further contaminated once it leaves the processing plant and travels to the store. Testing chicken bought from a retailer is in all likelihood a better ...
Clark G. Tristshauser, MD, Medina, N.Y.. Stool culture is the best way to diagnose infection with Campylobacter, which is the most common bacterial cause of infectious colitis. In most patients, symptoms resolve without need for antibiotic therapy. Antibiotics should be given for those who are severely ill, elderly, pregnant, or immunosuppressed. Erythromycin is the drug of choice (500 mg twice daily for five days); macrolides can be used for resistant strains. For strains resistant to erythromycin or fluoroquinolone, try azithromycin or clarithromycin. In the event of severe systemic infections, an aminoglycoside or carbapenem can be used ...
US - Revised guidelines have been published by the US Department of Agriculture’s Food Safety and Inspection Service (FSIS) to assist poultry processors in controlling Salmonella and Campylobacter in raw food products and prevent cases of foodborne illness.
The report also shows a total of 5,648 food-borne outbreaks recorded across the EU in 2011. Food-borne outbreaks include two or more human cases in which the same contaminated food has been consumed. These affected 69,553 people and caused 93 deaths. Salmonella continued to be the most frequently reported cause of the outbreaks with known origin (26.6 per cent of all outbreaks), followed by bacterial toxins (12.9 per cent) and Campylobacter (10.6 per cent ...
1. A medium was formulated to support aerobic growth of Campylobacter, bacterium associated with processed poultry that is recognized as a major cause of human, bacterial foodborne illnesses. Current methods for growing this pathogen require expensive equipment to produce atmospheres containing less oxygen and more carbon dioxide than normal atmospheres. Initial experiments indicated that supplementing a basal medium composed of tryptose, yeast extract, and a mineral-vitamin solution with organic acids supported the aerobic growth of this pathogen. Additional experiments indicated adding agar and sodium bicarbonate to the media enhanced aerobic growth of Campylobacter. Experiments were conducted to compare growth of the bacteria under aerobic and microaerobic conditions by inoculating the medium with Campylobacter then incubating aerobically or microaerophilically for 72 h at 37C, and enumerating the number of Campylobacter/ml recovered from the media. There was also a 5 to 6 log increase in the ...
Food borne diseases are receiving high priority in human nutrition. Campylobacter is a major cause of such a gastrointestinal disease, which to a large extent is attributed to poultry. Tackling this contamination throughout the chain seems to be the solution.

Biological molecules, like organisms themselves, are subject to genetic drift and may even become "extinct". Molecules that are no longer extant in living systems are of high interest for several reasons including insight into how existing life forms evolved and the possibility that they may have new and useful properties no longer available in currently functioning molecules. Predicting the sequence/structure of such molecules and synthesizing them so that their properties can be tested is the basis of "molecular resurrection" and may lead not only to a deeper understanding of evolution, but also to the production of artificial proteins with novel properties and even to insight into how life itself began ...

View more ,Abstract: Campylobacter species are the most common cause of foodborne disease in Australia and many countries throughout the World. Although campylobacteriosis is usually self-limiting, severe cases and those in the young, elderly and immunocompromised require antibiotic therapy. Antibiotic resistant Campylobacter isolates however may prolong illness and increase the risk of invasive disease. Antibiotic resistance in Campylobacter is thought to have arisen through the selective pressure of exposure to antimicrobial agents in veterinary medicine or animal husbandry, leading to the acquisition and dissemination of antibiotic resistance determinants, and genetic elements that harbour such genes, amongst isolates. Little was known about tetracycline and trimethoprim resistance in Australian campylobacters, including the presence of resistance genes and associated genetic elements. Aims of this study were therefore to identify in Australian Campylobacter jejuni and Campylobacter coli ...

Campylobacter species are one of the leading causes of foodborne disease in the United States. Campylobacter jejuni and Campylobacter coli are the two main species of concern to human health and cause approximately 95% of human infections. Molecular typing methods, such as pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) are often used to source track foodborne bacterial pathogens. The aim of the present study was to compare PFGE and MLST in typing strains of C. jejuni and C. coli that were isolated from different Oklahoma retail meat sources. A total of 47 Campylobacter isolates (28 C. jejuni and 19 C. coli) isolated from various retail meat samples (beef, beef livers, pork, chicken, turkey, chicken livers, and chicken gizzards) were subjected to pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). PFGE was able to group the 47 Campylobacter isolates into two major clusters (one for C. jejuni and one for C. coli) but failed to differentiate the
Biopsy specimens of gastric and duodenal mucosa from 290 patients were examined histologically for metaplasia and Campylobacter pyloridis. Estimates of pH on samples of fasting gastric juice from 55 of the patients were performed, and mucosal biopsy specimens from 33 patients were also cultured for C pyloridis. Active duodenitis was seen in 34 duodenal biopsy specimens. Thirty (88%) of the patients with active duodenitis had both greater than 5% gastric metaplasia in the duodenal specimen and C pyloridis associated gastritis. These two factors coexisted in only 0.43% of patients with no duodenal inflammation. When C pyloridis were seen histologically in duodenal biopsy specimens they were confined to areas of gastric metaplasia and never occurred in the absence of a polymorph infiltrate. Of the 55 patients with measurements of gastric juice pH, gastric metaplasia was present in the duodenum in 20 of 42 with a pH of less than 2.5, and in 0 of 13 with a pH of greater than 2.5. These results ...
Duodenal biopsy specimens from 80 patients with chronic renal failure, who were undergoing haemodialysis, were examined by light microscopy for evidence of inflammation, gastric metaplasia, and Campylobacter pylori infection. Chronic duodenitis was present in 47 (59%) of patients, of whom only seven (9%) showed evidence of active inflammation. Gastric metaplasia was present in 50 (62.5%) of patients, yet Campylobacter pylori was identified in only two patients (2.5%). It is suggested that the duodenal environment of patients with chronic renal failure remains hostile to the growth of these organisms in spite of the presence of gastric metaplasia.. ...
The failure to reduce the Campylobacter contamination of intensively reared poultry may be partially due to Campylobacter resisting disinfection in water after their internalization by waterborne protozoa. Campylobacter jejuni and a variety of waterborne protozoa, including ciliates, flagellates, and alveolates, were detected in the drinking water of intensively reared poultry by a combination of culture and molecular techniques. An in vitro assay showed that C. jejuni remained viable when internalized by Tetrahymena pyriformis and Acanthamoeba castellanii for significantly longer (up to 36 h) than when they were in purely a planktonic state. The internalized Campylobacter were also significantly more resistant to disinfection than planktonic organisms. Collectively, our results strongly suggest that protozoa in broiler drinking water systems can delay the decline of Campylobacter viability and increase Campylobacter disinfection resistance, thus increasing the potential of Campylobacter to ...
Conventional crossbred pigs from different sources and of different weights were examined for susceptibility to porcine proliferative enteritis. The ileal mucosa of pigs with the disease was emulsified and suspended in Mueller-Hinton broth. Pigs weighing 15, 120 and 200 lb (6.8, 54.5 and 91 kg) (four pigs per group) were stressed and inoculated orally with 80 ml of emulsified proliferative ilea. Severe lesions of porcine proliferative enteritis were detected in three of the four pigs weighing 6.8 kg. Mild lesions were detected in two of the four pigs in each of the other two groups. Gross lesions consisted of reticulation of the serosa, and hyperaemia and thickening of the mucosa with either fibrin or blood clots adherent to the mucosal surface. Inflammation, numerous mitotic figures and epithelial cell proliferation were observed microscopically in the crypts. Silver stained sections revealed numerous comma-shaped organisms in the crypts of infected epithelial cells. Using this method, serial ...
