Abstract
A 2-year-old female spayed Epagneul-Breton dog was presented with ecchymoses, but an undisturbed general condition. Clinical examination additionally revealed petechia and a haematoma. Travel history included Italy and Denmark. Laboratory abnormalities were moderate thrombocytopenia, prolonged PT, aPTT and TT, and elevated d-dimers. Initial therapy consisted of plasma transfusions, fluids, doxycycline and famotidine administration. Babesiosis, ehrlichiosis, leishmaniosis, dirofilariosis or anaplasmosis could not be confirmed. Abdominal ultrasound was unremarkable, while thoracic radiographs showed a bronchointerstitial pattern. Faecal samples collected over 3 days were positive for Angiostrongylus vasorum after examination using the Baermann lungworm test. The A. vasorum infection was successfully treated with fenbendazole, whereupon thrombocytopenia and prolonged coagulation times were resolved. In regions of low prevalence, an infection with A. vasorum should also be considered as a differential diagnosis in dogs with coagulation abnormalities. Respiratory signs can be absent with this disease. The patient may have acquired the infection abroad or in Germany.

Abstract
OBJECTIVE The Rivalta's test is used to diagnose feline infectious peritonitis (FIP) in cats with effusion. Only little information on the influence of sample storage and reaction conditions on test results is available, and diagnostic sensitivity and specificity to diagnose FIP vary considerably between few available studies. This study determined the influence of storage of effusion, modifications on reaction conditions, and inter-observer variation. MATERIAL AND METHODS The Rivalta's test was repeated up to 21 days after storage at room temperature, in the refrigerator, or freezer. The test was performed by two independent, blinded investigators. It was also performed using different volumes of acetic acid, different acids, and different kinds of water. RESULTS Even after storage for 21 days, test results were comparable. While inter-observer variation revealed substantial disagreement, different modifications in performance showed no major influence on test outcome. CONCLUSION The Rivalta's test seems to be a very robust test concerning storage conditions. Modifications in reaction condition also do not substantially influence outcome. However, the test is subjective and depends on the evaluating person.

Abstract
OBJECTIVE The aim of the study was to establish reference values for haematological and clinical-chemical parameters in adult dogs and to evaluate whether they are influenced by age, sex and feeding. MATERIAL AND METHODS The study population consisted of 508 clinically healthy dogs of both genders and different breeds aged between ≤ 1 and 17 years. To establish reference values, results of 396 dogs aged 1-9 years were used. Analysis of haematological and clinical-chemical parameters was performed using the following devices: Cell-Dyn 3500, Hitachi 911, GEM Premier 3000 and the coagulometer BE CL 4. The statistical program SPSS was used to calculate the reference values. RESULTS In 75% of the tested parameters no major discrepancies were noted in comparison to existing reference values. For eosinophils, basophils, monocytes, alanine aminotransferase, alkaline phosphatase, glutamate dehydrogenase, lipase, creatine kinase, bilirubin and creatinine cleardeviationsfromthe existing referencevalues were demonstrated. The reference ranges for eosinophils, monocytes and glutamate dehydrogenase were higher than reported inthe literature whereas for basophils they were lower. The reference ranges for the enzymes alanine aminotransferase, alkaline phosphatase, and lipase in young (< 1 year) and old dogs (≥ 10 years) differed significantly from the reference values of dogs aged 1-9 years. CONCLUSION AND CLINICAL RELEVANCE Reference require regular re-evaluation because through continuing developments and new knowledge, some factors related to their determination, particularly methods and equipment, change.

Abstract
Current global patterns of biodiversity result from processes that operate over both space and time and thus require an integrated macroecological and macroevolutionary perspective. Molecular time trees have advanced our understanding of the tempo and mode of diversification and have identified remarkable adaptive radiations across the tree of life. However, incomplete joint phylogenetic and geographic sampling has limited broad-scale inference. Thus, the relative prevalence of rapid radiations and the importance of their geographic settings in shaping global biodiversity patterns remain unclear. Here we present, analyse and map the first complete dated phylogeny of all 9,993 extant species of birds, a widely studied group showing many unique adaptations. We find that birds have undergone a strong increase in diversification rate from about 50 million years ago to the near present. This acceleration is due to a number of significant rate increases, both within songbirds and within other young and mostly temperate radiations including the waterfowl, gulls and woodpeckers. Importantly, species characterized with very high past diversification rates are interspersed throughout the avian tree and across geographic space. Geographically, the major differences in diversification rates are hemispheric rather than latitudinal, with bird assemblages in Asia, North America and southern South America containing a disproportionate number of species from recent rapid radiations. The contribution of rapidly radiating lineages to both temporal diversification dynamics and spatial distributions of species diversity illustrates the benefits of an inclusive geographical and taxonomical perspective. Overall, whereas constituent clades may exhibit slowdowns, the adaptive zone into which modern birds have diversified since the Cretaceous may still offer opportunities for diversification.

Abstract
This case report describes the disease progression of a male cat with pericardial effusion. Clinical signs (dyspnea, lethargy, and weakness) started very acutely. The initial laboratory profile showed only an increase in alanine aminotransferase enzyme activity. Diagnostic imaging revealed pericardial effusion. Effusion analysis showed a Rivalta-positive, modified transudate. Detection of feline coronavirus antigen in macrophages was negative. General condition and laboratory parameters dramatically worsened within seven days. Therefore, the owners decided to euthanize the cat. Even if effusion variables are macroscopically and microscopically suspicious for FIP, a definitive diagnosis of FIP could only be made by histology (including immunhistochemical staining).

Abstract
Due to increasing numbers of dogs that are imported from, or have been visiting Mediterranean countries, canine leishmaniasis has become a very important infectious disease in Germany. The aim of this study was to determine which laboratory and clinical parameters can be used as prognostic factors, whether level of antibody titre is a prognostic factor, and whether treatment leads to a better prognosis in a country in which reinfection is extremely unlikely. Data of 72 dogs infected with Leishmania infantum that had been presented to the Clinic of Small Animal Medicine of the LMU University of Munich, Germany, and whose owners answered a detailed questionnaire, were reviewed retrospectively. All dogs included in the study had clinical signs compatible with canine leishmaniasis. No correlation between the level of antibody titres (carried out by immunofluorescence assay) and survival time was found (p = 0.982). However, there was a significant correlation between survival time and presence of proteinuria (p < 0.001), hypoalbuminemia (p = 0.002), and lymphopenia (p = 0.040) in all treated dogs. Furthermore, treatment of diseased dogs resulted in a longer survival time (p = 0.003). In conclusion, levels of antibody titres did not correlate with prognosis. More useful parameters to predict shorter survival were proteinuria, hypoalbuminemia and lymphopenia. Also, treatment was correlated with a longer survival of almost two years.

Abstract
Progressive infection with feline leukaemia virus (FeLV) is considered one of the major risk factors for development of feline lymphoma. The aim of this study was to compare cats with lymphoma between 1980 and 1994 (first period) and between 1995 and 2009 (second period) concerning FeLV antigenaemia and age distribution. In addition, differences between FeLV antigen-positive and antigen-negative cats with lymphoma regarding patients' characteristics, tumour location and outcome were evaluated. There was a significant decrease in the percentage of lymphoma cases associated with progressive FeLV infection from the first (59 per cent) to the second (13 per cent) observation period. FeLV antigen-positive cats were significantly younger (median 3.7 v 11.3 years), and had significantly shorter response duration (median 25 days v 472 days) with therapy. In the cats of the second period, gastrointestinal and extranodal lymphomas were the most common anatomical sites, and the majority of those cats were FeLV antigen-negative. Thus, other aetiologies than progressive FeLV infection must have a greater impact on cancerogenesis among affected cats with lymphoma to date.

Abstract
BACKGROUND Bicyclam derivatives inhibit feline immunodeficiency virus (FIV) replication through selective blockage of chemokine receptor CXCR4. HYPOTHESIS/OBJECTIVES CXCR4 antagonist plerixafor (AMD3100, 1,1'-bis-1,4,8,11-tetraazacyclotetradekan) alone or combination with adefovir (PMEA, 9-(2-phosphonylmethoxyethyl)adenine) safe and effective for treating FIV-infected cats. ANIMALS Forty naturally FIV-infected, privately owned cats. MATERIALS AND METHODS Prospective, placebo-controlled, double-blind clinical trial. Cats randomly classified into 4 treatment groups. Received AMD3100, PMEA, AMD3100 in combination with PMEA, or placebo for 6 weeks. Clinical and laboratory parameters, including CD4(+) and CD8(+) cell counts, FIV proviral and viral load measured by quantitative polymerase chain reaction (qPCR) evaluated. Additionally, FIV isolates from cats treated with AMD3100 tested for drug resistance. RESULTS FIV-infected cats treated with AMD3100 caused significant decrease in proviral load compared to placebo group (2.3 ± 3.8% to 1.9 ± 3.1%, of blood lymphocytes P < .05), but did not lead to improvement of clinical or immunological variables; it caused a decrease in serum magnesium concentration without clinical signs. No development of resistance of FIV isolates to AMD3100 found during treatment period. PMEA administration improved stomatitis (stomatitis score [degree 1 - 100] PMEA group: 23 ± 19 to 11 ± 10, P < .001; AMD3100 + PMEA group: 12 ± 17 to 3 ± 5, P < .05), but did not decrease proviral or viral load and caused anemia (RBC [× 10(6) /μL] PMEA group: 9.07 ± 1.60 to 6.22 ± 2.16, P < .05; AMD3100 ± PMEA group: 8.80 ± 1.23 to 5.84 ± 1.58, P < .001). CONCLUSIONS AND CLINICAL IMPORTANCE Administration of CXCR4 antagonists, as AMD3100, can induce reduction of proviral load and may represent viable treatment of FIV-infected cats. Combination treatment with PMEA not recommended.

Abstract
Leitlinien sind systematisch erarbeitete Empfehlungen, um Kliniker und Praktiker bei Entscheidungen zur Versorgung ihrer Patienten im Rahmen spezifischer Umstände zu unterstützen. Leitlinien gelten für „Standardsituationen“ und berücksichtigen die aktuellen, zu den entsprechenden Fragestellungen zur Verfügung stehenden wissenschaftlichen Erkenntnisse. Leitlinien bedürfen der ständi-gen Überprüfung und eventuell der Ände-rung auf dem Boden des wissenschaftlichen Erkenntnisstandes und der Praktikabilität in der täglichen Praxis. Leitlinien entbinden den Arzt nicht von seiner Sorgfaltspflicht und der Beachtung der individuell angepassten diagnostischen und therapeutischen Maß-nahmen. Leitlinien erheben keinen Anspruch auf Vollständigkeit.

Abstract
Background Currently there is no drug proven to effectively treat cats with feline infectious peritonitis (FIP). Hypothesis Propentofylline (PPF) can decrease vasculitis, and therefore prolong survival time in cats with FIP, and increase their quality of life. Animals Twenty‐three privately owned cats with FIP. Methods Placebo‐controlled double‐blind trial. FIP was confirmed by histology or immunostaining of feline coronavirus (FCoV) antigen in effusion or tissue macrophages or both. The cats were randomly selected for treatment with either PPF or placebo. All cats received additional treatment with glucocorticoids, antibiotics, and low molecular weight heparin according to methods. Results There was no statistically significant difference in the survival time of cats treated with PPF (8 days, 95% CI 5.4–10.6) versus placebo (7.5 days, 95% CI 4.4–9.6). The median survival time of all cats was 8 days (4–36 days). There was neither a difference in quality of life (day 7, P = .892), in the amount of effusion (day 7, P = .710), the tumor necrosis factor‐alpha (TNF‐α) concentration (day 7, P = .355), nor in any other variable investigated in this study, including a complete blood count, and a small animal biochemistry profile. Conclusions and Clinical Importance This study did not detect an effect of PPF on the survival time, the quality of life, or any clinical or laboratory parameter in cats with FIP. Therefore, PPF does not appear to be an effective treatment option in cats with a late stage of the disease FIP.

Abstract
This study investigated doxycycline-related side effects in a large population of dogs. Data from 386 dogs that had received doxycycline for the treatment of various infectious diseases were analysed retrospectively. Potential side effects that developed during treatment were documented, and correlations with signalment, dose, duration of treatment, frequency of application, doxycycline preparation and use of additional drugs were investigated. Vomiting was reported in 18.3 per cent of dogs, 7.0 per cent developed diarrhoea and 2.5 per cent developed anorexia. While being treated with doxycycline, 39.4 per cent of dogs showed an increase in alanine aminotransferase (ALT) activity and 36.4 per cent showed an increase in alkaline phosphatase (ALP) activity. There was a dose-related risk of an increase in ALP activity (P=0.011, odds ratio [OR]=1.27, 95 per cent confidence interval [CI] 1.06 to 1.53), and older dogs treated with doxycycline were more likely to develop an increase in ALT activity (P=0.038, OR=1.23, 95 per cent CI 1.01 to 1.50) and vomiting (P=0.017, OR=1.11, 95 per cent CI 1.02 to 1.21).

Abstract
BACKGROUND Antibiotics generally are recommended to treat hemorrhagic gastroenteritis (HGE). Inappropriate use of antibiotics may promote risk of antimicrobial resistance and unnecessary adverse drug reactions. The necessity of antimicrobial therapy in dogs with HGE has not been demonstrated. OBJECTIVE The purpose of this prospective, placebo-controlled, blinded study was to evaluate whether treatment with amoxicillin/clavulanic acid improves the clinical course and outcome of HGE in dogs that show no signs of sepsis. ANIMALS The study included 60 dogs diagnosed with HGE between 2007 and 2009 at the Clinic of Small Animal Medicine, LMU University of Munich, Germany. The inclusion criterion was the presence of acute hemorrhagic diarrhea (<3 days). Dogs pretreated with antibiotics, with signs of sepsis, or diagnosed with any disease known to cause bloody diarrhea were excluded from the study. METHODS Patients were randomly divided into treatment (amoxicillin/clavulanic acid for 7 days) and placebo groups. To evaluate treatment efficacy, severity of clinical signs (based on a newly developed HGE index), duration of hospitalization, and mortality rate were compared between the 2 groups. RESULTS Fifty-three of 60 dogs completed the study. No significant difference between treatment groups concerning mortality rate, dropout rate, duration of hospitalization, or severity of clinical signs, either on any individual day or over the course of disease, was observed. CONCLUSIONS AND CLINICAL IMPORTANCE In some dogs with HGE that show no signs of sepsis, antibiotics may not change the case outcome or time to recovery.

Abstract
Amniotic fluid (AF) has become an interesting source of fetal stem cells. However, AF contains heterogeneous and multiple, partially differentiated cell types. After isolation from the amniotic fluid, cells were characterized regarding their morphology and growth dynamics. They were sorted by magnetic associated cell sorting using the surface marker CD 117. In order to show stem cell characteristics such as pluripotency and to evaluate a possible therapeutic application of these cells, AF fluid-derived stem cells were differentiated along the adipogenic, osteogenic, and chondrogenic as well as the neuronal lineage under hypoxic conditions. Our findings reveal that magnetic associated cell sorting (MACS) does not markedly influence growth characteristics as demonstrated by the generation doubling time. There was, however, an effect regarding an altered adipogenic, osteogenic, and chondrogenic differentiation capacity in the selected cell fraction. In contrast, in the unselected cell population neuronal differentiation is enhanced.

Abstract
OBJECTIVE The aim of this study was to evaluate differences between young cats (< 6 months) and adult cats (≥ 6 months) with feline panleukopenia with respect to clinical signs, laboratory abnormalities, environmental conditions, vaccination status, and outcome. MATERIAL AND METHODS Medical records of 244 cats diagnosed with panleukopenia between 1990 and 2007 at the Clinic of Small Animal Medicine, Ludwig-Maximilians University of Munich, Germany, were evaluated retrospectively. Cats that tested positive for feline panleukopenia virus (FPV) via electron microscopy, polymerase chain reaction (blood, faeces), antigen ELISA (faeces), or that had histopathological lesions consistent with panleukopenia at necropsy were included. Cats were excluded if they had been vaccinated against FPV within 3 weeks before admission. RESULTS In total 43.3% of cats were older than 6 months. There was no statistically significant difference between the two age groups regarding outcome, breed, sex, environmental conditions, vaccination status, clinical signs, and laboratory parameters with the exception of haematocrit: cats < 6 months had significantly lower haematocrit on the day of presentation than cats ≥ 6 months. CONCLUSIONS AND CLINICAL RELEVANCE Feline panleukopenia is predominantly in young cats, but older cats can also suffer from the disease. Although young cats are at a higher risk of infection, cats at the age of < 6 months suffering from clinical disease do not have a higher risk of death. Clinical presentation, laboratory abnormalities, prognosis, and outcome did not differ significantly between cats younger versus older than 6 months of age.

Abstract
OBJECTIVE of the study was to evaluate tissue velocity imaging (TVI) with respect to its reproducibility and to introduce reference values in a large canine population. In addition, the influence of gender, heart rate, age, weight and breed of the dogs was evaluated. MATERIAL AND METHODS A total of 199 healthy dogs were included. The longitudinal TVI was recorded from an apical four-chamber view using colour Doppler technique in unsedated dogs. Each myocardial wall was recorded as a single wall image, aligning the ultrasound beam as parallel as possible to the longitudinal motion of the respective wall. Off-line analysis was performed using the Q-analysis software. RESULTS Coefficients of variance for intrareader and interreader variability for each parameter were less than 10.0% and 12.4%, respectively. Tissue velocities were heterogeneously distributed within the myocardium, demonstrating an apico-basal gradient. Whereas gender did not influence TVI variables, heart rate, age, breed and weight had a significant influence on the tissue velocity. CONCLUSION AND CLINICAL RELEVANCE TVI is a sophisticated and promising echocardiographic technique. It is relatively easy to perform and can be included in the evaluation of systolic and diastolic myocardial function in routine daily practice. One limitation is that it is influenced by heart rate, age, breed and weight of the dogs. This study provides a basis for further investigation on this topic and supplies reference values for different weight groups in dogs.
