Evaluating the safety and efficacy of cryopreserved ovarian tissue transplantation in leukemia patients with different bone marrow remission status using xenotransplantation.

Background: Leukemia patients undergoing cryopreserved ovarian tissue transplantation (OTT) may carry a high risk of disease induction. Measurable residual disease (MRD) in bone marrow is linked to an elevated risk of relapse. It is controversial whether leukemia patients must be allowed to achieve measurable residual disease negative (MRD-negative) status instead of measurable residual disease positive (MRD-positive) status before ovarian tissue cryopreservation (OTC). Objective: To explore the safety and efficacy of OTT in acute leukemia patients with different MRD status by using xenotransplantation. Method: Cryopreserved ovarian tissue from 19 leukemia patients was thawed and xenotransplanted to ovariectomized BALB/C nude mice (n=36). The mice were divided into 2 groups based on the patient's MRD status before OTC: MRD-negative group (n=18) and MRD-positive group (n=18), additionally, a control group consisted of ovariectomized mice (n=9). Body weight was measured weekly and mortality, emaciation, and other abnormalities were recorded. Twenty-six weeks post-surgery, livers, spleens, uteruses, and ovarian grafts were removed for macroscopic and histological examinations to evaluate the efficacy of xenotransplantation and assess malignant cell contamination in mice. Results: Follicle growth was visible in the ovarian grafts of the MRD-negative and MRD-positive groups. Compared with the ovariectomized group, a significant decrease in body weight (p<0.01) was noted, the uterine volume was notably larger, estradiol (E2) levels were significantly higher (p<0.01), and follicle-stimulating hormone (FSH) levels were significantly lower (p<0.001) in the other two groups. Mice in the MRD-positive group showed a significantly higher incidence of death (p<0.001) and emaciation (p<0.01), compared to the MRD-negative group. Histological observation revealed the presence of malignant cells in the grafts, livers, and spleens of 3 mice in the MRD-positive group. No abnormalities were observed in the mice from the MRD-negative group in both macroscopic and histological observations except one mouse was sacrificed for ascites unrelated to leukemia relapse. Conclusion: For leukemia patients having ovarian tissue preserved in the first and only centralized human ovarian tissue cryobank in China, immunodeficient mice xenotransplantation can be a method to evaluate the safety and efficacy of OTT; the risk of malignant cell reimplantation due to OTT is higher in leukemia patients with MRD-positive status than those with MRD-negative status before OTC.

Necropsy findings, meat control pathology and causes of loss in semi-domesticated reindeer (Rangifer tarandus tarandus) in northern Norway.

BACKGROUND: Reindeer herding in Norway is based on traditional Sámi pastoralism with the animals free ranging throughout the year. The animals move over large areas in varying terrain and often in challenging weather conditions. Winter crises, such as difficult grazing conditions caused by icing or large amounts of snow, are survival bottlenecks for reindeer. Calves are especially vulnerable, and many may die from starvation during winter crises. Predation and starvation are the predominant narratives to explain losses, however, carcasses are difficult to find and often little remains after scavenging and decay. Documentation of the causes of death is therefore scarce. RESULTS: In this study, we investigated the cause of reindeer mortality in Troms and Finnmark, Nordland and Trøndelag during 2017-2019. Necropsies (n = 125) and organ investigation (n = 13) were performed to document cause of death. Body condition was evaluated using visual fat score and bone marrow fat index. A wide range of causes of death was detected. The diagnoses were categorized into the following main categories: predation (n = 40), emaciation (n = 35), infectious disease (n = 20), trauma (n = 11), feeding related disease (n = 5), neoplasia (n = 4), others (n = 6) and unknown (n = 17). Co-morbidities were seen in a number of diagnoses (n = 16). Reindeer herders are entitled to economic compensation for reindeer killed by endangered predators, but a lack of documentation leads to a gap between the amount of compensation requested and what is awarded. An important finding of our study was that predators, during winter, killed animals in good as well as poor body condition. Emaciation was also shown to be associated with infectious diseases, and not only attributable to winter grazing conditions. CONCLUSIONS: This study highlights the importance of examining dead reindeer to gain knowledge about why they die on winter pasture. The work presented herein also shows the feasibility and value of increased documentation of reindeer losses during winter.

Comparison of specificity and sensitivity of diagnostic methods for Enteromyxum leei and Enteromyxum fugu detected from cultured tiger puffer, Takifugu rubripes in Korea.

Enteromyxum leei and Enteromyxum fugu, which are myxosporean parasites, were first found in cultured tiger puffer Takifugu rubripes in Korea. We collected four tiger puffers that showed severe emaciation signs for our experiments. DNA sequencing was confirmed that the tiger puffers were coinfected with E. leei and E. fugu. Furthermore, similar amounts of E. leei and E. fugu were confirmed using real-time PCR in the intestine. To the best of our knowledge, there have been no reports of E. fugu infection in the olive flounder Paralichthys olivaceus. However, the diagnosis of inflowing water, discharged water and olive flounder samples using highly sensitive diagnostic methods confirmed the presence of E. fugu in water and fish samples from olive flounder farms near the tiger puffer farm. Therefore, the present study aimed to develop highly sensitive diagnostic methods such as real-time and two-step PCR for early diagnosis and follow-up of the emaciation disease and multiplex PCR for rapid diagnosis. The multiplex PCR method exhibited the same sensitivity as the one-step PCR method developed in this study, demonstrating its efficacy for rapid diagnosis. Therefore, the suggested methods can be utilized for the early diagnosis and rapid diagnosis of emaciation diseases and reduction of economic losses through rapid disease control.

OBJECTIVES: To investigate the nutritional status and its influencing factors in children with newly diagnosed inflammatory bowel disease (IBD). METHODS: A retrospective analysis was conducted on the clinical data of children who were diagnosed with IBD for the first time in Hunan Children's Hospital from January 2015 to December 2021. Diagnostic delay was defined as the time from the symptom onset to IBD diagnosis being in the upper quartile (P76-P100) of all IBD children in the study. Multivariate logistic regression analysis was used to explore the risk factors for emaciation and growth retardation. RESULTS: A total of 125 children with newly diagnosed IBD were included, with Crohn's disease being the main type (91.2%). The rates of emaciation and growth retardation were 42.4% (53 cases) and 7.2% (9 cases), respectively, and the rate of anemia was 77.6% (97 cases). Diagnostic delay was noted in 31 children (24.8%), with the time from the symptom onset to IBD diagnosis of 366 to 7 211 days. Multivariate logistic regression analysis showed that diagnostic delay was a risk factor for emaciation and growth retardation (OR=2.73 and OR=4.42, respectively; P<0.05) and that age was positively associated with emaciation (OR=1.30, P<0.05). CONCLUSIONS: Children with newly diagnosed IBD have poor nutritional status, and the rates of anemia, emaciation, and growth retardation are high. Diagnostic delay is associated with malnutrition in children with IBD.

Diencephalic syndrome-like presentation of brainstem tumor: a series case-based review.

PURPOSE: Russel described a rare clinical entity known as diencephalic syndrome (DS) in 1951, which was traditionally caused by a neoplasm in the hypothalamic-optic chiasmatic region. DS is characterized by severe emaciation despite adequate or slightly reduced caloric intake, locomotor hyperactivity, euphoria and other minor features. Current evidence suggests that a rare population of children with a similar phenotype may have their tumor located in the posterior fossa instead, defining the DS-like presentation, a rare entity with few cases reported in the literature. METHODS: A thorough search of three databases (PubMed, Ovid Medline, and Ovid Embase) was conducted to identify relevant papers reporting children with DS associated with brainstem tumors. To our knowledge, only seven cases have been documented in the literature. Moreover, we present four of our own cases, focusing on the unusual clinical presentation, the diagnosis process, and the lag time between the initial symptoms and the definitive diagnosis. RESULTS: In this review, the mean lag time between the onset of symptoms and diagnosis was 20.9 months (median: 16 months; range: 1.5-72 months), whereas in our series of cases, the time was 32.5 months (median: 33 months; range: 7-57 months). CONCLUSION: Despite recent significant advances in neuro-oncology diagnostic tools, this mean lag time did not improve when compared with the previous literature review from 1976. Throughout these data, we aim to raise awareness in the hopes of detecting intracranial neoplasms earlier in cases of children with profound emaciation of unknown cause.

USING WILDLIFE REHABILITATION AND POSTMORTEM DATA TO IDENTIFY KEY CAUSES OF MORBIDITY AND MORTALITY IMPACTING THE HEALTH AND WELFARE OF FREE-LIVING WILD ANIMALS IN CANADA.

The health and welfare of wild animals are of increasing concern, yet there are very few large-scale data syntheses examining how causes of wildlife morbidity and mortality vary across time, space, and taxa. Records for 18,540 animals submitted to the Canadian Wildlife Health Cooperative (CWHC) (2009-19) and 144,846 animals admitted to 19 wildlife rehabilitation centers (WRCs) (2015-19) were evaluated to 1) identify the main causes of morbidity and mortality for Canadian wildlife and 2) assess the utility and complementarity of these two data sources to further our understanding of wildlife health. The CWHC cases (mortality) were examined by pathologists and grouped by the presence or absence of five diagnostic categories: trauma, emaciation, infection or inflammation, toxicity, and other. These CWHC animals were also classified as "killed due to real or perceived human-wildlife conflict" based on finder history. The WRC admissions were categorized by health issue (according to intake records) and based on reported or observed situational reasons for admission: parental loss, unsafe or unsuitable location, nest or habitat disturbance, illegal possession, and abnormal behavior. For both datasets, the main reason for submission or admission was trauma (44 and 48%, respectively), especially vehicle collisions (7 and 11%) and window or building strikes (5 and 7%). Many other WRC admissions were due to parental loss (28%), cat attacks (6%), and immature animals being found in unsafe or unsuitable locations (6%). Most other CWHC mortalities were caused by infections (27%) and emaciation (23%). Relatively few birds, amphibians, and reptiles submitted to CWHC were killed due to human-wildlife conflict, but 22% of mammals were killed for this reason, highlighting the taxonomic differences in the perceived threat of wildlife to finders, and therefore their response. Together, these data sources highlight key issues impacting the health and welfare of wild animals in Canada.

Parasitism of Nelore (Bos indicus) calf from northern Brazil by Ctenocephalides felis.

Ctenocephalides felis is the most common hematophagous ectoparasite of domestic cats and dogs worldwide, causing allergic dermatitis, anemia, itching, discomfort, and it is responsible for the transmission of many pathogens. In cattle, parasitism is not common but occurs due to the high adaptability of this flea species. This study aimed to report infestation of a Nellore (Bos indicus) calf from Northern Brazil by C. felis and its clinical findings. A 45 kg male calf presented diarrhea, progressive emaciation after 50 days of birth, and flea infestation. Anemia was observed (4.11 × 106/µL of erythrocytes; 20.48% of hematocrit). Coproparasitological examination and molecularly detection of Anaplasma spp. and Babesia spp. indicated negatively. Fleas were collected and taxonomically identified as C. felis. Clinical manifestations of this ectoparasite in cattle were unspecific; however, they can develop severe conditions, such as restlessness and weakness, accompanied by alopecia, emaciation, anemia, and edema of the lower limbs with intense itching and self-excoriation.

Long-term exposure to environmental levels of phenanthrene induces emaciation-thirst disease-like syndromes in female mice.

Phenanthrene (Phe) is a polycyclic aromatic hydrocarbon widely present in foods and drinking water. To explore the detrimental effects of Phe on body metabolism, female Kunming mice were treated with Phe in drinking water at concentrations of 0.05, 0.5 and 5 ng/mL. After exposure for 270 d, the animals exhibited dose-dependent reduced body weight and increased water consumption. The dose-dependent accumulation of Phe in the brain decreased hypothalamic neuron numbers, upregulated hypothalamic expression of anaplastic lymphoma kinase, elevated norepinephrine levels in white adipose tissue (WAT) and further activated lipolysis in WAT, leading to a reduction in fat mass. Brown adipose tissue formation was reduced, accompanied by the inhibition of the bone morphogenetic protein signaling pathway. A simultaneous reduced serum levels of antidiuretic hormone (arginine vasopressin) might be one of the reasons for increased water consumption. The present results indicate an environmental etiology and prevention way for the development of emaciation-thirst disease.

Laparoscopic transabdominal preperitoneal hernioplasty for bilateral obturator hernias and left inguinal hernia with emaciation caused by anorexia nervosa: A case report.

A 55-year-old woman receiving treatment for anorexia nervosa presented with abdominal pain and right thigh pain. Her body mass index was 12.9 kg/m2 . Computed tomography showed fluid storage in the distal side of the right obturator foramen and revealed a dilated small bowel without a starting point of obstruction. We diagnosed a naturally reduced incarcerated right obturator hernia and performed elective surgery with a laparoscopic approach for hernia repair the next day. Intraperitoneal observation revealed bilateral obturator hernias and a left direct-type inguinal hernia. Transabdominal preperitoneal hernioplasty was performed using two self-gripping polyester meshes for bilateral obturator hernia repair and a lightweight 3D-shaped mesh for left inguinal hernia repair. Women with emaciation caused by anorexia nervosa may be more likely to have complex hernias, including obturator hernia, and laparoscopic approaches may be useful for preoperatively diagnosed nonstrangulated obturator hernias.

[Germinoma in a patient with emaciation and growth retardation. Case report]. / Germinoma en un paciente con emaciación y retraso de crecimiento. A propósito de un caso.

Central nervous system tumors are the second most frequent oncological disease among children and teenagers. Among the intracranial tumors, the germ cells ones are infrequent. The symptoms they cause are headaches, nausea and vomiting, hormonal deficits, visual disturbances, weight loss, poor growth and early puberty. Less frequently, they produce movement or psychiatric disorders. Some of these tumors can be asymptomatic for a long period leading to a late diagnosis. The case of a 14-year-old female patient is presented. She showed weight loss and growth failure, with wrong diagnosis of eating disorder. After proper study methods, we arrived to central nervous system germinoma diagnosis. Because this pathology is rare and has a variable form of presentation, it requires that the family involved and the health team to be alert, to avoid delays in diagnosis and treatment.

Los tumores del sistema nervioso central representan la segunda enfermedad oncológica más habitual en niños y adolescentes. Entre los tumores intracraneales, los de células germinales son infrecuentes. Los síntomas que desencadenan son cefalea, náuseas, vómitos, déficits hormonales, alteraciones visuales, pérdida de peso, pobre crecimiento y pubertad precoz. Menos frecuentemente, producen trastornos del movimiento o psiquiátricos. Algunos de estos tumores pueden ser asintomáticos un largo período, lo que desencadena un diagnóstico tardío. Se presenta a una paciente femenina de 14 años con pérdida de peso y falla del crecimiento, con diagnóstico erróneo de trastorno de la conducta alimentaria. Tras estudios pertinentes, se arribó al diagnóstico de germinoma del sistema nervioso central. Al ser esta patología infrecuente y de presentación variable, requiere alto sentido de alerta por parte de la familia involucrada y del equipo de salud para evitar retrasos en el diagnóstico y el tratamiento.

Non-invasive hormone monitoring as a robust method for determining adrenocortical activity in injured, emaciated and oil-contaminated African penguins undergoing rehabilitation.

Anthropogenic activity is a major driver of seabird injury and mortality in the 21st century. Although most seabirds perish within the natural environment as a result of human activities, some are rescued and admitted to rehabilitation centres. Despite the considerable number of admissions, little is known regarding the physiological response seabirds have to specific admission reasons and the rehabilitation process. In this study, we aimed to determine the effect of injury, emaciation, oiling, individual removal from the natural environment and the rehabilitation process on the physiological stress response of the African penguin (Spheniscus demersus). Urofaecal samples were collected from African penguins throughout a three-stage rehabilitation process and quantified for glucocorticoid metabolites (ufGCM). The three stages included an initial ICU crate stage (Stage 1), an ICU pen stage (Stage 2) and a rehabilitation stage (Stage 3). Data were analysed using a generalised linear model in order to determine the effect of admission reason, age and rehabilitation stage (Stage 1, 2 and 3) on ufGCM levels. Although the model indicated that only Stage 1 was a significant driver of adrenocortical activity in the study population, ufGCM levels of injured and emaciated animals within Stage 1 were considerably higher than those of birds with any other admission reason across all stages. This is the first study examining the causes and effect of rehabilitation on the physiological stress response in African penguins. Enhanced care and attention should be given to rescued individuals, especially during the first stage of rehabilitation, to reduce perception of additional stressors and thus increase the chance of full recovery.

Effect of late versus early initiation of parenteral nutrition on weight deterioration during PICU stay: Secondary analysis of the PEPaNIC randomised controlled trial.

BACKGROUND & AIMS: Critically ill children are at increased risk of weight deterioration in the paediatric intensive care unit (PICU). Whether early initiation of parenteral nutrition (PN) prevents weight deterioration is unknown. The aims of this study were to assess the effect of withholding supplemental PN during the first week on weight Z-score change in PICU and to evaluate the association between weight Z-score change in the PICU and clinical outcomes. METHODS: This is a secondary analysis of the Paediatric Early versus Late Parenteral Nutrition in Intensive Care Unit (PEPaNIC) randomised controlled trial (N = 1440), which focused on the subgroup of patients with longitudinal weight Z-scores available on admission and on the last day in PICU. Patients were randomly allocated to initiation of supplemental PN after one week (Late-PN) or within 24 h (Early-PN) when enteral nutrition was insufficient. The effect of Late-PN versus Early-PN on the change in weight Z-score was investigated, adjusted for risk factors. Moreover, the association between weight Z-score change and clinical outcomes was explored, adjusted for risk factors. RESULTS: Longitudinal weight Z-scores were available for 470 patients. Enteral nutrition intake was equal in the Early-PN and Late-PN group. Less weight Z-score deterioration during PICU stay was associated with a lower risk of new infections (adjusted OR per Z-score increase 0.72 [0.55-0.96], p = 0.02), and with a higher likelihood of an earlier discharge from PICU alive (adjusted HR per Z-score increase 1.22 [1.10-1.37], p < 0.001). During PICU-stay, the change in weight Z-score did not differ among both groups (Late-PN median 0.00 [-0.34-0.12] vs Early-PN median -0.03 [-0.48-0.01], adjusted ß = 0.10 [-0.05-0.25], p = 0.18). CONCLUSIONS: Weight deterioration during the PICU stay was associated with worse clinical outcomes. Withholding supplemental PN during the first week did not aggravate weight Z-score deterioration during PICU stay. TRIAL REGISTRATION: clinicaltrials.gov NCT01536275.

Severe infection caused by nymphs of Armillifer armillatus (Pentastomida, Porocephalidae) in a leopard, Panthera pardus, in the Kruger National Park, South Africa.

The necropsy of an adult male leopard, Panthera pardus, shot in the Kruger National Park, revealed the presence of large numbers of Armillifer armillatus nymphs in the intestine, liver, spleen, mesentery, peritoneal fold, mediastinum and lungs. The animal had been observed to be blind in the right eye and severely debilitated. The infection with A. armillatus clearly contributed to its emaciation and anaemia. Armillifer armillatus is a parasite of snakes, using mammals that form part of the snakes' prey as intermediate hosts. It is also one of the pentastomids with the highest zoonotic potential in Africa. It is unclear if the leopard's partial blindness and injuries of its extremities forced it to forego larger prey items for easier prey, such as snakes, and this in turn led to exposure to this unusual parasite, or if he had simply developed a preference for snakes. The incidental finding of A. armillatus in a large carnivore emphasises the importance of necropsies in expanding our knowledge on wildlife diseases.

Emaciation and Sporadic Mortality in Older Laying Hens Caused by Intussusception of the Proventriculus.

Laying hens (n = 2267) ranging in age from 2 to 4 yr in a study evaluating ovarian cancer prevention were necropsied. Those that died or were culled during the 2-yr study (n = 1591) were necropsied weekly to determine the most probable cause of death or culling and cancer status. Hens surviving until the end of the study (n = 676) were euthanized and necropsied. Hens necropsied before and after a hen with proventricular intussusception served as cohorts (n = 38). Nineteen hens (13 dead, 6 culled) had intussusceptions of the proventriculus into the ventriculus. Mean age of affected hens was 154 wk (range 110-204 wk). None of the hens in the study had an intestinal intussusception, and none of the hens euthanized at the end of the study had a proventricular intussusception. Hens with proventricular intussusceptions were severely emaciated; mean body weights were 1040 and 1736 g for affected and cohort hens, respectively. Necropsy findings included prominent keel, marked muscle atrophy, generalized serous atrophy of fat, no visible proventriculus, esophagus directly entering the ventriculus, and an enlarged, spherical, firm ventriculus, which contained an invaginated, swollen, diffusely ulcerated proventriculus. Eighteen affected hens were anovulatory (94.7%) compared to 27 cohorts (71.1%). Severe, diffuse necrosis and ulceration of the proventricular mucosa was confirmed microscopically, but no etiologic agent was identified. In conclusion, proventricular intussusception of undetermined etiology was identified as a cause of sporadic emaciation, culling, and mortality in older laying hens.

Reporte de caso- Emaciación y mortalidad esporádica causadas por intususcepción del proventrículo en gallinas de postura maduras. Se realizaron necropsias de gallinas ponedoras (n=2267) de dos a cuatro años de edad en un estudio que evaluó la prevención del cáncer de ovario. Las aves que fueron eliminadas semanalmente durante el estudio de dos años (n=1591) se sometieron a la necropsia para determinar la causa más probable de muerte o de desecho y el estado de cáncer. Las gallinas que sobrevivieron hasta el final del estudio (n=676) se sacrificaron y se les realizó la necropsia. Las gallinas a las que se les practicó la necropsia antes y después de la intususcepción proventricular sirvieron como cohortes (n=38). Diecinueve gallinas (13 muertas y seis sacrificadas) tuvieron intususcepciones del proventrículo dentro de la molleja. La edad media de las gallinas afectadas fue de 154 semanas (con un rango de 110 a 204 semanas). Ninguna de las gallinas en el estudio mostró una intususcepción intestinal y ninguna de las gallinas sometidas a eutanasia al final del estudio tuvo una intususcepción proventricular. Las gallinas con intususcepciones proventriculares estaban severamente emaciadas; los pesos corporales medios fueron 1040 g y 1736 g para las gallinas afectadas y para las gallinas cohorte, respectivamente. Los hallazgos de la necropsia incluyeron la quilla de la pechuga prominente, atrofia muscular marcada, atrofia serosa de la grasa generalizada, no proventrículo visible, esófago entrando directamente en la molleja y una molleja esférica y firme, que contenía un proventrículo, invaginado, abultado y difusamente ulcerado. Dieciocho gallinas afectadas fueron anovulatorias (94.7%) en comparación con 27 cohortes (71.1%). La necrosis y la ulceración severas y generalizadas de la mucosa proventricular se confirmaron microscópicamente, pero no se identificó ningún agente etiológico. En conclusión, la intususcepción proventricular de etiología indeterminada se identificó como una causa de emaciación esporádica, sacrificio y mortalidad en gallinas ponedoras maduras.

Nutrition consult was sought and he was found to have a BMI of 6.8kg/m2. He was started on nutrition support along with supportive therapy, which resulted in weight gain and improvement in his condition.

Methodology of Maternal and Child Health Populational Surveys: A Statewide Cross-sectional Time Series Carried Out in Ceará, Brazil, from 1987 to 2017, with Pooled Data Analysis for Child Stunting.

BACKGROUND: Cross-sectional studies are fundamental studies in the practice of epidemiological science. This article aims to present in detail the methodology for conducting a series of cross-sectional studies, as well as the analysis of data through pooled data. METHODS: The series of studies are population cross-sectional studies, with statewide coverage, searching for representative sample of reproductive aged women and pre-school children in Ceará, Brazil. The sampling plan followed simple random, stratified, systematic and by conglomerates, in sequence. About 300 variables were collected. For each of the individual studies, multivariate data analysis was used to verify associations between dependent variables. For all the studies together, techniques used were trend chi-squared and pooled data analysis using linear mixed modeling procedures. RESULTS: There were 6 studies in sequence, for 30 years. Among other findings, the variables income, maternal education and breastfeeding time proved to be associated with the reduction of malnutrition in children considering all the period (p values 0.013, 0.033 and 0.037, respectively). CONCLUSIONS: Cross-sectional studies can be replicated at regular time series following the methodology exposed in this, even for locations with limited resources, ensuring adequate management of decisions of using federal funding aimed at achieving targeted programs to maximize the results obtained with the public resource available.

Spontaneous outbreak of Astragalus pehuenches (Fabaceae) poisoning in cattle in Argentina.

This is the first report of a spontaneous outbreak of Astragalus pehuenches poisoning on a farm in Argentine Patagonia, where 63 out of 70 cattle died. The main clinical signs of affected animals were ataxia, balance loss and progressive emaciation. Purkinje cells presented vacuolation and marginalization of the nucleus. Astragalus pehuenches was detected in the paddock as well as in the ruminal content and fecal matter samples of the affected animals. Swainsonine concentrations in Astragalus specimens were found to be as high as 0.096%.

Hepatic Dicrocoelium dendriticum infection in a miniature horse.

A miniature horse which died following humane seizure from an Ontario farm was emaciated with serous atrophy of fat. Autopsy revealed hepatic atrophy and moderate periportal fibrosis. Eggs and trematodes seen in the liver were identified as Dicrocoelium dendriticum. This appears to be the first reported case of infection of equids in North America with Dicrocoelium dendriticum.

Un cheval miniature qui est mort à la suite d'une saisie humanitaire dans une ferme de l'Ontario était émacié et avait une atrophie séreuse des tissus adipeux. L'autopsie a révélé une atrophie hépatique et une fibrose périportale modérée. Des oeufs et des trématodes observés dans le foie ont été identifiés comme Dicrocoelium dendriticum. Il semblerait qu'il s'agit du premier cas signalé d'infection des équidés par Dicrocoelium dendriticum en Amérique du Nord.(Traduit par Isabelle Vallières).

Invasive Colonic Entamoebiasis in Wild Cane Toads, Australia.

We detected a disease syndrome in free-ranging Australian cane toads involving atypical behavior and emaciation that is associated with a previously undescribed Entamoeba sp. that infiltrates the colonic lining, causing it to slough. The organism may become seasonally pathogenic when toads are under hydric and nutritional stress.
