Although most acute renal failure the ability to concentrate urine and retain sodium also in the newborn resolves, ischemic injury severe enough to result depends on gestational age. Chromosomal abnormalities and syndromes with multiple anomalies frequently include renal abnormalities. Such infants will generally also have pulmonary hypopla sia, and die from pulmonary rather than renal insufficiency. Rising serum creatinine; hyperkalemia; metabolic aci Ultrasonography identifies many infants with renal anoma dosis; fluid overload.

This figure shows the arrangement of the operon for to xins A and B of Clostridium difficile. The operon TcdB 270kD also carries a gene, TcdE, which produces a E T protein protein that is thought to assist in the TcdA 308kD release of the to xins across the bacterial E T cell wall. Each protein genes domains has an enzyme active domain E TcdD positive regula to r E enzyme activity glucosyltransferase (glucosyltransferase); a domain responsible TcdC negative regula to r T translocation across host membrane for binding B, which consists of multiple TcdE enzyme that may assist release of B oligopeptide repeat units involved oligopeptide repeat units; and a domain T to xins from the bacterial cell in binding to host recep to rs that is involved in translocation of the to xin TcdB to xin TcdA to xin across the host cell membrane. The pattern of bands produced by the restriction enzyme is characteristic for the different ribotypes and the patterns can be used to determine if there is cross infection or a common source outbreak where the bands would be identical. In neonates it is believed, based mostly on animal data, that they do not have the necessary adhesion to allow the to xin to bind. In adults who develop the illness the usual his to ry is of an elderly patient coming in to hospital, either already carrying C. Current thinking is that first antibiotics are given, which disturb the normal flora and appear to create an ecological niche where C. Those who arrive in the hospital already carrying the organism appear relatively protected from disease. Thus, arriving as a carrier may represent prior exposure with subsequent development of some type of immunity, as yet poorly defined. The environmental fac to rs that stimulate the to xin genes to be switched on and cause disease are unknown. In experimental systems it is known that consumption of some amino acids or the production of volatile fatty acids by the indigenous microflora inhibits the proliferation of C. It is also known that viable intestinal microflora is important in inhibition of out growth of C. Why dis ease affects the elderly more commonly than younger patients is also not known, although the disease is occurring increasingly in the younger age group, which might be associated with more virulent strains (see Section 3). Spread within the body the organism remains within the gastrointestinal tract and only rarely is extra-intestinal disease reported. Spread from person to person Patients with diarrhea, especially if it is severe or accompanied by incon tinence, may unintentionally spread the infection to other patients in hospital. In 2007 the number of cases recorded in patients over 65 years was 49 785 and since manda to ry reporting of cases less than 65 years old was introduced in April 2007 the number of cases reported in this age group to the end of 2007 was 7597. This strain produces large amounts of to xin A and B and in some strains a binary to xin. Immune responses Although some information has accumulated on the development of immune responses during infection with C. Systemic and mucosal antibodies (IgG and IgA) are produced by the host to the A and B to xins in some patients following C. Low levels of antibodies with low avidity for A and B to xins, typically acquired early in life, have been found in the serum of up to 70% of asymp to matic adults, which are probably not effective in preventing the initial infection. Understanding the immune response to this commensal is clearly of importance in protection against the severe consequences of infection. Pathogenesis TcdA binds to carbohydrate Gal-b 1,4N-Acetyl Glucosamine by repeat units at the C-terminal end of the to xin. Both TcdA and B are taken up in to the cy to sol of host colonocytes and are glucosyltransferases that inac tivate Rho, Rac, and Cdc42, thereby affecting actin polymerization. This leads to impairment of tight junctions, cell rounding up, and cell death (Figure 6). TcdB activates Ca influx, which is necessary for the disintegra tion of the actin cy to skele to n. Infection has usually occurred in those aged over 65 years and usually in association with antibiotics, bowel surgery or chemotherapeutic agents. The illness may follow antibi otics taken briefly or even several weeks previously. Mode of action of Clostridium host cell cy to plasmic membrane difficile to xins A/B. This figure shows the action of the to xins A and B on the host recep to r-mediated TcdB cell. The to xins morphology inhibit the normal functioning of glucose TcdA G proteins Rho, Rac, and Cdc42 by G TcdB G actin cy to skele to n glucosylating them. The recruitment of polymorphonuclear leukocytes by interleukin-8 to xins also stimulate the release of cy to kines. These relatively rare cases have been caused by hypervirulent strains such as ribotype 027. Patients present with colicky abdominal pain, bloating, and watery diarrhea with an almost characteristic smell for C. Toxic mega colon may occur, which can paradoxically cause diarrhea to s to p or in some cases not to appear at all, and colec to my may be required. The rare patients with extra-intestinal disease almost always have long term carriage of the organism or severe gastrointestinal disease. An additional assay that is likely to be useful is the detection of glutamate dehydrogenase in the feces as a surrogate marker for the organism. Culture is also available and is important for the investigation of suspected outbreaks where the isolates can be ribotyped. Pseudomembranous colitis is diagnosed by colonoscopy where raised yel lowish plaques may be seen on the mucosa. If severe disease is suspected lim ited sigmoidoscopy may be used as colonoscopy may result in perforation. The differential diagnosis includes other infective causes of diarrhea, inflamma to ry bowel disease, and diverticulitis. Management For patients who are on antibiotics and who develop diarrhea, one should s to p the antibiotics if at all possible. Vancomycin and metronidazole must be given orally, although metronidazole may also be given parenterally. Pulsed or tapering doses of both antibiotics have been given at the end of the course of treatment and vancomycin has also been given by enema. In mild to moderate disease both are equally effective but in severe disease vancomycin was more effective in a controlled trial. Other antibiotics that have been used are bac itracin, fusidic acid, nitazoxanide, and rifaximin. Rifampin, which had been rec ommended, has not been effective in a controlled trial. Alternative treat ments are also available including cholestyramine (which binds the to xin but also binds vancomycin, so the two should not be given simultaneously); monoclonal anti- to xin antibodies; intravenous immune globulin (although there are no controlled trials and reported results are contradic to ry); probiotics such as Saccharomyces boulardiae (which is really a strain of S. Prevention In hospitals and nursing homes, prevention is by strict control-of-infection procedures. If more than one patient has the illness the patients should be nursed in a dedicated ward. A decision whether to close the ward/unit must be made on an individual basis but if there is evidence of widespread cross-infection then the unit should be closed. All items and rooms after discharge of the patient(s) should be cleaned in the same manner. Attention to hand-wash ing practices is important and should be undertaken with soap and water rather than alcohol, as the latter has no effect on the spores of C. There is currently no vaccine although research is ongoing with at least two candidate vaccines.

The patient was referred for out that during the previous year she had had several surgery where the prosthetic graft was resected and episodes of fever, which resolved without medical help. Due to the infection the prosthetic graft beats/minute and an arterial pressure 110/46 mmHg. However, labora to ry tests showed a white blood was prescribed: doxycycline and hydroxychloroquine. After 10 diagnosis of cardiac endocarditis, but detected large months the patient was well, although antibiotic therapy vegetations in the prosthetic tube (Figure 1A). There was no recurrent infection of the blood cultures were sterile, serological tests revealed homograft tube. The patient is infected with Coxiella burnetii and is suffering from chronic Q fever. A spore-like stage does not have dipicolinic acid or a spore coat with cysteine characteristic for other gram-positive bacterial spores. Humans usually become infected from cattle, goats, sheep, domestic rumi nants, and pets or contaminated dung and bedding. Cats and dogs can become infected through tick bites, eating contaminated placentas or milk, and by the aerosol route. However, ticks may contribute to the infec tion of wild animals such as rodents and wild birds. Although genomic strain variations are associated with the geo graphic distribution of isolates it appears that host susceptibility to C. Detection of antibodies to the antigens expressed by these two forms is used in diagnosis (see Section 4). Only exposure to high (fi to 5%) concentra tions of formalin for no less than 24 hours may kill C. Its cell wall is rich with proteins and peptidogly can that may render the bacterium high resistance to harsh environmental conditions. Which of these is involved in attachment determines successful internalization and survival in macrophages and monocytes (see Section 2). The dissemination route is mostly via the blood monocytes and, rarely, through the gastrointestinal route by drinking raw milk or eating raw cheese or raw eggs. Spread from person to person Person to person transmission of the bacteria is extremely rare. There are some cases described when human Q fever infection has occurred in an obstetrician who performed an abortion on a pregnant parturient woman, or during au to psies, intradermal inoculation, and blood transfusion. Risk fac to rs Q fever is considered to be an occupational hazard for farmers, veterinar ians, abat to ir workers, and labora to ry personnel. People in charge of pet dogs and cats are also at risk, particularly if present at their birth. Age appears to be a risk fac to r for Q fever: symp to matic Q fever is more likely to occur in those 15 years old or above than in those under 15 years of age. There is some indication that although men and women seem to be equally susceptible to infection by C. The reasons for age and sex bias remain unknown, although this may be explained by the hormonal influences. Epidemiology Q fever has been reported in almost every country, except for New Zealand. However, since this disease does not reach epidemic proportions its detection and identification are not very accurate. The disease is endemic in California; a cat-associated outbreak was reported in 1989 in Goldsboro, Maine. In Canada, Q fever was diagnosed in Nova Scotia in 1981; most of the recent cases are associated with expo sure to infected cats, dogs, wild hares, and deer. In Europe, the majority of acute Q fever cases are diagnosed in spring and early summer, outside the lambing period, which correlates with increased contamination of the environment with C. Interestingly, detec tion of Q fever is very high in areas contaminated with rickettsia, although this can be due to a better organized epidemiological service. Incidence of acute Q fever is approx imately 50 per 100000 inhabitants per year, while Q fever-induced endo carditis is estimated to be 5% of all national endocarditis cases. Due to the current decline in rural population, Q fever is increasingly diagnosed in the urban population, after occasional exposure to infected animals or con taminated raw milk with a peak in spring or early summer. Several outbreaks were associated with living near flocks of sheep, and here the prevalent mode of contamination was considered to be air-borne.

Clinical Infectious Diseases 2007;45:941 2007 by the Infectious Diseases Society of America. The highest incidence is reported from Austria, the Czech Republic, Germany, and Slovenia, as well as from the northern countries bordering the Baltic Sea. Ticks may live for more than three years and are highly sensitive to changes in seasonal climate. Indirectly, climate affects both tick and pathogen occurrence through effects on habitat conditions and reservoir animal density. In addition, climate-induced changes in land use and in recreational behaviour influence human exposure to infected ticks and thus disease prevalence. Since the 1980s, tick vec to rs have increased in density and spread in to higher latitudes and altitudes in Europe. There is a need to strengthen preventive measures such as information to the general public, surveillance activities within a pan-European network and to use standardized methods to provide data for future research activities.

Important changes in climatic conditions are predicted and these will have implications for human health in Europe. About 85 000 cases are reported annually in Europe (estimated from available national data). In the United States between 15 000 and 20 000 cases are registered each year and the disease is currently endemic in 15 states (Steere, 2001). Following the discovery in 1982 of the spirochete (spiral-shaped bacterium) Borrelia burgdorferi s. Spirochetes are maintained in nature in ticks and in the blood of certain animal species: in Europe particularly insectivores, small rodents, hares and birds. Humans as well as larger animals, such as deer and cattle, do not act as reservoirs for the pathogen. Current knowledge of the impact of different climatic fac to rs on vec to r abundance and disease transmission is rather extensive. In addition, daily climatic conditions during several seasons (as ticks may live for more than three years) influence tick population density both directly and indirectly. During the last decades ticks have spread in to higher latitudes (observed in Sweden) and altitudes (observed in the Czech Republic) in Europe and have become more abundant in many places (Talleklint & Jaenson, 1998; Daniel et al. These tick distribution and density changes have been shown to be related to changes in climate (Lindgren et al. However, studies from localized areas that have reliable long-term surveillance data show that such incidence increases are real, and that they are related to the same climatic fac to rs that have been shown to be linked to changes in tick abundance (Lindgren, 1998; Lindgren & Gustafson, 2001; Daniel et al. Where the two species overlap there are microclimatic conditions separating their distribution. Recent studies of the Baltic regions of the Russian Federation showed for example that 11. In addition, a large number of other tick species have been reported as carriers of B. Seasonal climatic conditions limit the latitude and altitude distribution of ticks in Europe (Daniel, 1993; Lindgren et al. At high northern latitudes, where the inland climate generally is to o harsh for ticks to survive, small tick populations can be found in locations where the landscape characteristics help in modifying the climatic conditions. Incidence Surveillance in Europe varies and does not allow direct comparison between countries. In addition, data obtained from various European labora to ries are often not directly comparable because of different serological tests used to detect antibodies to B. Despite these caveats, it appears that both disease incidence and antibody prevalence are higher in the central and eastern parts of Europe than in the western parts (Table 1). A gradient of decreasing incidence from south to north in Scandinavia and from north to south in Italy, Spain and Greece has also been noted. This is partly due to an increased level of awareness in the general population and among medical personnel, and to better reporting. However, studies from the Czech Republic and Sweden show changes in vec to r abundance as well as changes in latitudinal or altitudinal distribution of ticks during the same time period (Talleklint & Jaenson 1998; Daniel et al. The possible fac to rs underlying these reported changes will be discussed in the sections below. However, there exist valid serological data from some extensive studies, such as those of Berglund et al. Possible causes of inter annual variations in incidence will be discussed in the sections below. Lyme borreliosis incidence, Czech Republic 70 60 50 40 30 20 10 0 199019911992199319941995199619971998199920002001 Fig. This has been shown in several studies on antibody prevalence in human blood and on disease incidence (Cris to folini et al. Higher seroprevalence of antibodies has been reported for men, probably owing to higher exposure to ticks (Carlsson et al. The highest risk periods from a public health point of view take place when peaks in tick activity occur simultaneously with peaks in human visits to tick infested areas. These seasonality patterns are explained by the fact that more people than usual visit B. Several genospecies may be present simultaneously both in infected ticks (Schaarschmidt et al. Different clinical manifestations are often associated with the different genospecies, as are different reservoir hosts; see Table 5, in Section 7. However, this does not seem be the case in the Russian Federation and eastern parts of Europe where non-specific maintenance cycles involving small mammals and various borrelia species have been described (Gorelova et al. Of about 850 described species of ticks world-wide this family is the most important from a medical and veterinary point of view (Sonenshine, 1991). Woodlands are preferred to open land, with a preference for deciduous compared to coniferous woodlands (Adler, 1992; Glass et al. On-going studies show that not only are woodland habitats important but habitat configuration, i.
