Abstract
Transmission of bacteria vertically through host tissues ensures offspring acquire symbionts; however, horizontal transmission is an effective strategy for many associations and plays a role in some vertically transmitted symbioses. The bivalve Solemya velum and its gammaproteobacterial chemosynthetic symbionts exhibit evolutionary evidence of both transmission modes, but the dominant strategy on an ecological time scale is unknown. To address this, a specific primer set was developed and validated for the S. velum symbiont using a novel workflow called specific marker design (SMD). Symbionts were quantified in spawned eggs and sediment and seawater samples from S. velum habitats with qPCR. Each egg was estimated to contain 50-100 symbiont genomes. By contrast, symbiont DNA was found at low abundance/occurrence in sediment and seawater, often co-occurring with host mitochondrial DNA, obscuring its origin. To ascertain when eggs become infected, histological sections of S. velum tissues were labelled for symbiont 16S rRNA via in situ hybridization. This revealed symbionts in the ovary walls and mature oocytes, suggesting association in late oogenesis. These data support the hypothesis that S. velum symbionts are vertically transmitted every host generation, thus genetic signatures of horizontal transmission are driven by ecologically infrequent events. This knowledge furthers our understanding of vertical and horizontal mode integration and provides insights across animal-bacterial chemosynthetic symbioses.

Abstract
1. The objective of this study was to evaluate the effect of ferric tyrosine on the reduction of Campylobacter spp. and zootechnical performance in broilers exposed to Campylobacter spp. using a natural challenge model to simulate commercial conditions. Additionally, the minimum inhibitory concentrations (MICs) of ferric tyrosine against common enteropathogens were evaluated. 2. At the start of the trial, 840 healthy male 1-d-old birds (Ross 308) were randomly allocated to 6 replicate pens of 35 birds each and fed diets containing different concentrations of ferric tyrosine (0, 0.02, 0.05 and 0.2 g/kg) in mash form for 42 d. 3. Broilers fed diets containing ferric tyrosine showed significantly higher body weight at d 42 and weight gain compared to the control group. However, birds fed ferric tyrosine ate significantly more than the control birds so significant improvements in feed conversion rate were not observed. 4. Microbiological analyses of caecal samples collected on d 42 of the study showed, per gram of sample, 2-3 log10 reduction in Campylobacter spp. and 1 log10 reduction in Escherichia coli in the groups fed diets containing ferric tyrosine compared to the control. 5. The MICs of ferric tyrosine was >400 mg/l for C. jejuni and >200 mg/l for E. coli and Salmonella enterica, indicating that ferric tyrosine did not exert antimicrobial activity. 6. The results showed that birds fed ferric tyrosine grew faster and consumed more feed compared to the control group, indicating potential benefits of faster time to reach slaughter weight with no significant reduction on feed efficiency. Moreover, ferric tyrosine significantly reduced caecal Campylobacter spp. and E. coli indicating potential as a non-antibiotic feed additive to lower the risk of infections transmitted through the food chain.

Abstract
Probiotics are live microorganisms ingested for the purpose of conferring a health benefit on the host. Development of new probiotics includes the need for safety evaluations that should consider factors such as pathogenicity, infectivity, virulence factors, toxicity, and metabolic activity. Clostridium butyricum MIYAIRI 588® (CBM 588®), an anaerobic spore-forming bacterium, has been developed as a probiotic for use by humans and food animals. Safety studies of this probiotic strain have been conducted and include assessment of antimicrobial sensitivity, documentation of the lack of Clostridium toxin genes, and evaluation of CBM 588® on reproductive and developmental toxicity in a rodent model. With the exception of aminoglycosides, to which anaerobes are intrinsically resistant, CBM 588® showed sensitivity to all antibiotic classes important in human and animal therapeutics. In addition, analysis of the CBM 588® genome established the absence of genes for encoding for α, β, or ε toxins and botulin neurotoxins types A, B, E, or F. There were no deleterious reproductive and developmental effects observed in mice associated with the administration of CBM 588®. These data provide further support for the safety of CBM 588® for use as a probiotic in animals and humans.

Abstract
PURPOSE Quality of life in women receiving adjuvant endocrine therapy for breast cancer (BC) may be impaired by hot flushes and night sweats. The cool pad pillow topper (CPPT) is a commercial product, promoted to improve quality of sleep disrupted by hot flushes. This study aimed to identify if the CPPT reduces severity of sleep disturbance by minimising effects of hot flushes. METHODS This randomised phase II trial, recruited women with BC, on adjuvant endocrine therapy, experiencing hot flushes and insomnia. Participants were randomised (stratified by baseline sleep efficiency score (SES) and menopausal status) to the intervention arm (CPPT + standard care) or control arm (standard care). Participants completed Hospital Anxiety and Depression Scale and Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaires and fortnightly sleep/hot flush diaries (where responses were averaged over 2-week periods). The primary endpoint was change in average SES from -2 to 0 weeks to 2 to 4 weeks. RESULTS Seventy-four pre- (68.9 %) and post-menopausal (31.1 %) women were recruited. Median age was 49.5 years. Endocrine therapies included tamoxifen (93.2 %). Median SES at weeks 2 to 4 improved in both arms but the increase on the intervention arm was almost twice that on the control arm (p = 0.024). There were significantly greater reductions in hot flushes and HADS depression in the intervention arm (p = 0.09 and p = 0.036, respectively). There were no significant differences in FACT-B or HADS anxiety. CONCLUSION This study supports the use of the CPPT as an aid to reduce sleep disturbance and the frequency/severity of hot flushes.

Abstract
AIM Current management of locally advanced rectal cancer includes neoadjuvant chemoradiation in selected patients to increase the chance of a tumour-free circumferential resection margin. There is uncertainty over the role of and selection criteria for additional systemic therapy in this group of patients. In this retrospective study we investigate the association between markers of systemic inflammatory response (SIR) and outcome from treatment. METHOD One hundred and fifteen patients with locally advanced rectal cancer undergoing preoperative chemoradiation had recording of full blood count parameters including neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratios (PLR). Postoperative surgical margins (R status) and pathological stage were documented. Outcome measures were overall survival (OS), time to local recurrence (TTLR) and disease-free survival (DFS). Cox regression analysis was performed to identify predictors of outcome. RESULTS Only NLR and R status were significant predictors for all outcome measures on univariate and multivariate analysis. Elevated NLR (≥5) was associated with decreased OS, [hazard ratio (HR) and 95% CI, 7.0 (2.6-19.2)], decreased TTLR [HR 3.8 (1.3-11.2)] and shorter DFS [HR 4.1 (1.7-9.8)]. Median survival for patients with an elevated NLR was 18.8 months compared with 54.4 months without an elevated NLR (P<0.001). CONCLUSION In addition to postoperative R-status, an elevated NLR is also a valuable prognostic marker in patients undergoing chemoradiation for locally advanced rectal carcinoma. It is associated with worse OS, TTLR and DFS. An elevated NLR may be a useful additional tool in guiding the decision-making process for adjuvant or neoadjuvant therapies.

Abstract
OBJECTIVES To compare language outcomes following direct individual therapy [speech and language therapist (SLT) working individually with a child], indirect individual therapy [speech and language therapy assistant (SLTA) working individually with a child], direct group therapy (SLT working with a small group of children) and indirect group therapy (SLTA working with a small group of children) for primary school-age children with persistent primary receptive and/or expressive language impairment relative to a comparison group receiving current models and levels of SLT service. DESIGN The trial had a 2 x 2 factorial design (direct/indirect versus individual/group therapy) together with a control group that received existing levels of community-based speech and language therapy and served as a comparator for the economic analysis. All postintervention language outcome measures were blind assessed. A short-run economic evaluation across the four different modes of therapy was carried out using the primary outcome measure. A comparable method was used for estimating the costs of providing services in the community for children allocated to the control group. SETTING Research intervention took place in school settings in Scotland, with some of the children randomised to group therapies transported to join a group in a different school. PARTICIPANTS Children aged between 6 and 11 years, attending a mainstream school, with standard scores on the Clinical Evaluation of Language Fundamentals (CELF-3UK) of less than -1.25 SD (receptive and/or expressive) and non-verbal IQ on the Wechsler Abbreviated Scale of Intelligence (WASI) above 75, and no reported hearing loss, no moderate/severe articulation/phonology/dysfluency problems or otherwise requiring individual SLT work. Informed, written parental consent was required. INTERVENTIONS A therapy manual was constructed that provided a range of procedures and activities for intervention in areas identified by a search of the research and professional literature for examples of language therapies of proven effectiveness. SLTs planned activities for children seen by therapists and SLTAs, using the manual. MAIN OUTCOME MEASURES Primary outcome measures were standardised scores on tests of expressive and receptive language. Secondary outcome measures were scores on a test of receptive vocabulary, together with questionnaire, rating scale and focus group data from parents, teachers, project SLTs and SLTAs, and an audit of therapy sessions. RESULTS There was no evidence that the five modes involved in the project were different at the onset in terms of primary outcome measures, although there were significant gender differences. The results from both the intention-to-treat analyses of the outcomes from the 161 children randomised who met the eligibility criteria and the protocol analyses of the outcomes from the 152 children for whom postbaseline data were available revealed that there were no significant postintervention differences between direct and indirect modes of therapy on the one hand, or between individual and group modes on the other on any of the primary language outcome measures. However, there was evidence of some benefits from direct therapy from an SLT in secondary outcome measures. Intervention delivered three times a week for 30-40 minutes over a 15-week period also yielded significant improvements in age-corrected standardised scores for expressive language, although not for receptive language, relative to those receiving community-based SLT services. Children with specific expressive language delay were more likely to show improvement than those with mixed receptive-expressive difficulties, and non-verbal IQ was not a significant moderating variable. The within-trial economic evaluation identified indirect therapy, particularly indirect group therapy, as the least costly of the modes investigated in the study, with direct individual therapy as the most costly option. CONCLUSIONS SLTAs can act as effective surrogates for SLTs in the delivery of services within primary schools to children with primary language impairment who do not to require the specialist skills of an SLT. Generalising the central estimates of the relative cost of different therapy modes to other educational/health systems is possible, but the precise differences reported in resource use need to be qualified by the level of programme intensity and other characteristic features of education and therapy services that may differ from those observed in this trial. Further research is needed into effective interventions for receptive language problems and also investigations of the efficacy of the relationship between dose and treatment effect in both expressive and receptive language. Research is also needed into models of integrative service delivery, cluster models of delivery via integrated community schools, and the involvement of class teachers, classroom assistants and parents/carers. There is also a need for studies to identify the characteristics of children who are most likely to succeed with indirect intervention approaches, and also to evaluate alternative methods of working with those who may benefit from different modes. Finally, research to refine the therapy manual would also be helpful.

Abstract
BACKGROUND Roifman syndrome (OMIM 300258) is a multi-system disorder with a physical phenotype that includes Beta-cell immunodeficiency, intra-uterine and postnatal growth retardation, spondyloepiphyseal dysplasia, retinal dystrophy and characteristic facial dysmorphism. So far, six cases, all boys, have been reported in the literature. Roifman postulated that the syndrome may be due to a mutation in an X-linked gene or an autosomal gene giving rise to a sex-limited trait, but the definitive pathogenetic mechanism has still not been elucidated. Very little is known about the cognitive and behavioural phenotype of Roifman syndrome and no standardized measures of cognitive abilities have been reported. METHODS We report the seventh case of a boy with Roifman syndrome and present the first systematic documentation of the cognitive and behavioural phenotype of an individual with the syndrome. RESULTS In spite of having been reported as appearing intellectually 'able', formal evaluation showed very significant intellectual disability and neuropsychological impairment across cognitive domains. CONCLUSIONS The findings suggest that Roifman syndrome may be an example of an X-linked mental retardation syndrome (XLMRS).

Abstract
Panoramic Camera (Pancam) images from Meridiani Planum reveal a low-albedo, generally flat, and relatively rock-free surface. Within and around impact craters and fractures, laminated outcrop rocks with higher albedo are observed. Fine-grained materials include dark sand, bright ferric iron-rich dust, angular rock clasts, and millimeter-size spheroidal granules that are eroding out of the laminated rocks. Spectra of sand, clasts, and one dark plains rock are consistent with mafic silicates such as pyroxene and olivine. Spectra of both the spherules and the laminated outcrop materials indicate the presence of crystalline ferric oxides or oxyhydroxides. Atmospheric observations show a steady decline in dust opacity during the mission. Astronomical observations captured solar transits by Phobos and Deimos and time-lapse observations of sunsets.

Abstract
An experiment was designed to assess the effects of graded levels of beta-mannanase on performance and body weight uniformity of male broilers provided with diets based on corn and soybean meal and devoid of antibiotic growth promoters or coccidiostats. Four dietary treatments contained 0, 50, 80, and 110 MU of Hemicell/ ton (where 1 MU = 10(6) enzyme activity units, 100 MU/ton is manufacturer's recommendation). Each treatment contained 15 pens with 40 birds/pen. Individual bird weights were determined on d 0, 21, and 42. From 21 to 42 d of age, feed intake for the 80 MU/ton treatment was significantly greater than the 50 MU/ton treatment. beta-Mannanase inclusion at 80 or 110 MU/ton induced improvements (P < 0.05) in weight gain (3.9 to 4.8%) and feed efficiency (3.5 to 3.8%) over the control, whereas inclusion of 50 MU/ton resulted in no significant benefit. There were no significant differences between 80 or 110 MU/ton. The experiment demonstrated that dietary inclusion of beta-mannanase at approximately 50 MU/ton is not sufficient for maximum response. Inclusion at 80 MU/ ton improved broiler gains and feed conversion and increasing to 110 MU/ton resulted in no significant additional response.

Abstract
Panoramic Camera images at Gusev crater reveal a rock-strewn surface interspersed with high- to moderate-albedo fine-grained deposits occurring in part as drifts or in small circular swales or hollows. Optically thick coatings of fine-grained ferric iron-rich dust dominate most bright soil and rock surfaces. Spectra of some darker rock surfaces and rock regions exposed by brushing or grinding show near-infrared spectral signatures consistent with the presence of mafic silicates such as pyroxene or olivine. Atmospheric observations show a steady decline in dust opacity during the mission, and astronomical observations captured solar transits by the martian moons, Phobos and Deimos, as well as a view of Earth from the martian surface.

Abstract
We report major element composition ratios for regions of the asteroid 433 Eros imaged during two solar flares and quiet sun conditions during the period of May to July 2000. Low aluminum abundances for all regions argue against global differentiation of Eros. Magnesium/silicon, aluminum/silicon, calcium/silicon, and iron/silicon ratios are best interpreted as a relatively primitive, chondritic composition. Marked depletions in sulfur and possible aluminum and calcium depletions, relative to ordinary chondrites, may represent signatures of limited partial melting or impact volatilization.

Abstract
A systems approach is used to examine the barriers to collaboration found in the working practices of speech and language therapists and teachers. Functional, structural and systems-environment barriers are found, but few process barriers, which may explain why good collaborative practice can be found in the field. The differences that serve as barriers are listed and discussed, with a view to fostering mutual understanding between teachers and speech and language therapists.

Abstract
Reports on a survey of 1990 and 1991 graduates entering the speech and language therapy profession in the UK and on the experiences of six new therapists in one "good practice" area, Ayrshire and Arran Health Board. Results show that new therapists were given a great deal of help and support from professional managers, and valued it highly. They chose posts which offered a mixed client load and good induction packages. Pre-service training reflected work carried out in service, but all client groups had not been accessed during training. Issues relating to throughput and case-load management required most support. They made successful personal adaptations to the work environment, and managers found them effective overall. Calculates the costs of supporting new therapists. Highlights the need to maintain professional support and discusses the potential difficulties involved in doing so in relation to NHS reforms.

Abstract
This article presents a morphologic assessment of the effect of silicon nitride ceramic (Si3N4) on rabbit marrow stromal cells and their differentiation when grown in vitro and in vivo. In vitro marrow stromal cells (MSC) attached initially to upper portions of ceramic discs. However, at four weeks, cells only attached to disc edges. Fresh marrow or first passage MSC, inoculated into diffusion chambers with and without Si3N4, formed cartilage, bone, and fibrous tissue after being implanted intraperitoneally for five weeks. Tissue differentiated adjacent to Si3N4 but not within the pores. In contrast, Si3N4 implants inserted into femoral marrow cavities were surrounded initially by woven bone and within three months by mature bone that had permeated implants with a pore size of 255 +/- 64 microns. Plugs having a pore diameter of 170 +/- 45 microns mainly contained vascularized fibrous tissue with occasional foci of osteoid or bone in the peripheral pores. In a pilot experiment, three femoral segmental Si3N4 endoprostheses were implanted in three adult rabbits, and the osseous reactions were monitored during their natural life. Each implant was enclosed by a stable cuff of bone within four months of implantation and remained unchanged during the rest of the animal's life. Autopsies confirmed these roentgenographic observations, and tissue appositional to each prosthesis was morphologically normal. Si3N4 has the potential of an important ceramic for use in osseous reconstruction.

Abstract
Campylobacter mucosalis and C hyointestinalis have been associated with the proliferative enteropathies of pigs. An examination of the antibody response to these organisms and to the intracellular campylobacter-like organism was undertaken. Antibody to the campylobacter-like organism was predominantly IgM, short lived, and could be detected by an immunofluorescence test using bacteria released from lesions as antigen. The majority (75 per cent) of pigs with proliferative enteropathy at necropsy were antibody positive and a small number (4 per cent) of pigs in which lesions were not observed were found to have antibody. Antibody appeared to be correlated with the presence of lesions rather than with exposure to infection and was independent of the presence of antibody to C mucosalis or C hyointestinalis. In natural outbreaks of the disease antibody to the campylobacter-like organism was more prevalent than clinical signs in the affected animals.

Abstract
Following the transplantation of bone marrow cells to extra-osseous sites, bone formation occurs in those sites. This osteogenic potential of bone marrow cells might be utilized for filling defects in bone if they could be transported on porous ceramic materials. Before such an approach becomes feasible, it is important to know what happens to the cells in the presence of the ceramics that might be used. In order to investigate the interaction between bone marrow cells and ceramics, in vitro, a system for culturing bone marrow cells on ceramic materials has been developed. Bone marrow cells adhered well to the surface of calcium hydroxyapatite and tricalcium phosphate ceramics, and this was followed by the formation of fibrous tissue on and within the ceramics. These ceramics were compatible with bone marrow cells even in culture conditions in which there was a large surface area of ceramic interfacing with cells. The results support the proposal that calcium hydroxyapatite and tricalcium phosphate are appropriate as bone replacement materials. In contrast, calcium aluminate had an adverse effect on bone marrow cells when there was a high proportion of ceramic to culture medium. However, this effect was not present if the proportion of ceramic to culture medium was low. Therefore, a large amount of biodegradable porous calcium aluminate ceramic should not be used as an alternative to autogeneous bone grafting.

Abstract
The pathogenicity of classical enteropathogenic Escherichia coli strains of human origin was investigated in gnotobiotic piglets. One to two day old piglets in groups of four were infected perorally with approximately 10(8) colony forming units of one of eight enteropathogenic E coli strains or a non-pathogenic control strain. Animals were necropsied 24 or 48 hours after infection and their intestines were subjected to histological examination, quantitative bacterial culture and estimation of lactase activity. Four enteropathogenic E coli strains caused mild to moderate diarrhoea in nine of the 16 piglets inoculated with them. Piglets given two of these strains later became moribund. One enteropathogenic E coli strain caused a severe illness unaccompanied by diarrhoea. Inflammation of the intestinal mucosa occurred with all eight enteropathogenic E coli strains, but not with the control strain. Pathological changes were most pronounced in the distal ileum and colon and adherent bacteria were seen on the surface of the inflamed mucosa. The extent of the inflammatory response in infected piglets for the most part paralleled the severity of the clinical signs, the degree of bacterial colonisation and the reduction in lactase activity. Electron microscopic examination of tissue from piglets infected with three different strains showed that bacterial adherence to the apical plasma membrane of epithelial cells was accompanied by distinctive ultrastructural changes. These included degeneration of the microvillous brush border, together with cupping and pedestal formation of the plasma membrane at sites of bacterial attachment. The same changes have been seen in naturally occurring enteropathogenic E coli diarrhoea in humans and rabbits. The combined clinical and pathological findings indicate that the neonatal gnotobiotic piglet is a suitable model of infection with enteropathogenic E coli.

Abstract
Three different porous ceramics--calcium aluminate, calcium hydroxyapatite, and tricalcium phosphate--were implanted into the proximal tibia in rats and rabbits to study the interactions between these ceramics and a bony site that is abundant in bone marrow. New bone was consistently formed within the bone marrow surrounding and adjacent to all three types of ceramics. Calcium hydroxyapatite and tricalcium phosphate ceramics permitted bone ingrowth into their pores. The newly formed bone was found only in the part of the ceramic intruding into the bone, not in the portion protruding in the soft tissues outside the tibia. Partial replacement of the new bone opposite the medullary portion by new hemopoietic marrow occurred with longer implantation times. In contrast, no bone was seen within the pores of any of the calcium aluminate implants.

Abstract
Gnotobiotic pigs were dosed orally with Campylobacter sputorum subspecies mucosalis, either alone, or combined with rotavirus or non-pathogenic Escherichia coli and Streptococcus bovis to study the behaviour of C s mucosalis in defined conditions, to assess intracellular parasitism of enterocytes by C s mucosalis, and if possible to establish an experimental model of porcine intestinal adenomatosis. C s mucosalis colonised the gut of gnotobiotic pigs, persisting for up to 47 days after infection, but did not induce adenomatosis. Despite evidence of limited penetration of the mucosa up to two days after infection, the majority of C s mucosalis remained in the gut lumen. Rotavirus did not enhance invasion of enterocytes by C s mucosalis. The presence of E coli and S bovis caused an increase in the total numbers of C s mucosalis in the gut, but did not affect their distribution. Thus C s mucosalis was largely non-pathogenic in gnotobiotic pigs.

Abstract
The ability of four different ceramic materials to support osteogenesis when placed with bone marrow into an intermuscular site was studied. In the search for biodegradable porous ceramic materials that could be used for bone replacement and that would slowly be replaced by bone by means of "creeping substitution," the authors fabricated porous alumina, calcium aluminate, calcium hydroxyapatite, and tricalcium phosphate. Specially shaped compacts, impregnated with autologous bone marrow, were inserted into intermuscular pouches in rabbits and retrieved after 14-182 days. Newly formed bone was found within the contents of the well after 14 days and was visible at all times up to 182 days. The bone was frequently found to have adhered to the ceramic and to have penetrated the interior if the pore size was greater than 100 micron. Further investigation of the use of synthetic materials in bone replacement is warranted due to the finding that some porous ceramic material permit bony ingrowth from autologous marrow cells.

Abstract
Pigs affected with intestinal adenomatosis had agglutinating antibodies to Campylobacter sputorum subspecies mucosalis. The titres obtained varied, depending on the strain used as antigen and appeared to rise with the age of the affected animal. Examination of sera from experimental animals showed that pigs between 30 and 77 days old rarely had antibody, even when they had been exposed to infection. Evidence is also presented indicating that the serological response is specific and that in a limited examination of sera derived from pigs at slaughter almost all animals had high levels of antibody.

Abstract
Piglets from five litters were doses orally with cryptosporidium originally derived from diarrhoeic calves. The piglets were either nursed by the sow, artificially reared after sucking colostrum, or weaned on to creep feed. Colostrum-fed, artificially reared piglets obtained from two litters and exposed in the first week of life developed clinical signs of inappetence, vomiting and diarrhoea and shed oocysts in the faeces. Histologically the parasite was observed throughout the small and large intestine attached to epithelial cell surfaces and its presence was associated with extensive mucosal damage, particularly in the posterior small intestine, stunting and fusion of villi, immaturity of villous epithelial cells and oedema with increased cellularity of the lamina propria. Piglets from two other litters, both sucking and colostrum-fed artificially reared, exhibited similar but milder clinical signs. Histological lesions were less severe and cryptosporidium infection less extensive. When weaned piglets were exposed they remained clinically healthy although histologically there was evidence of cryptosporidium attachment in the small intestine and minor mucosal damage. There appears to be a good correlation between the extent of intestinal infection, the degree of mucosal damage and the severity of clinical disease induced by cryptosporidium in piglets.

Abstract
Hearing, speech, and language were studied in 26 children who survived severe perinatal asphyxia. The results of hearing tests showed that most children had a favourable outcome. Only 1 child had sensorineural deafness. Hearing loss in 6 others was due to middle-ear disease which resolved after treatment, and on retesting was found to be normal. The study also showed that neither gentamicin treatment nor incubator noise seemed to affect hearing. The results of speech and language assessment were less encouraging and about one-third of the children without serious mental or physical handicap had deficits in speech and language. It is suggested that the quality of life in such children could be improved if these deficits were detected early and adequately treated.

Abstract
Hearing and receptive vocabulary (E.P.V.T. full-range version) of the trainees of an adult training centre have been studied. A high incidence of hearing loss (47.1 per cent) was found. The correlation between receptive vocabulary and hearing loss was significant at the five per cent level for the adult Down syndrome subjects in the study. Recommendations are made on the services required, particularly with reference to audiology, that could significantly contribute to the reduction in the number of hearing-impaired mentally handicapped subjects who are at present in hospital care.

Abstract
This study indicates that viable Campylobacter sputorum subsp mucosalis are not present or are present in small numbers in the mucosa of pigs dying of proliferative haemorrhagic enteropathy. The changes present in the mucosa are similar to those seen in pigs recovering from adenomatosis and the evidence obtained indicates that the intracellular organisms observed in this condition are indeed mucosalis. The presence of large amounts of IgA in the altered tissue of both proliferative haemorrhagic enteropathy and porcine intestinal adenomatosis indicates that the failure to recover bacteria may be immunologically mediated but is not simply related to the presence or absence of antibody in the respective conditions.
