“…Infectious causes evaluated in this study were limited to parasitic or algae infections, and no viral or obligate enteropathogenic bacteria were identified as a primary cause of chronic diarrhea. Potentially pathogenic organisms can be frequently found in the feces of clinically healthy dogs and dogs with chronic enteropathy making it difficult to determine whether a specific organism identified acts as an etiologic factor, is a result of a changing microbiota due to the chronic enteropathy, or is in fact unrelated to the disease process . With respect to the multifactorial etiology of chronic enteropathies, the resolution of clinical signs after elimination of the identified organism is essential to determine disease causation .…”

BackgroundChronic diarrhea (CD) is common in dogs, and information on frequency and distribution of primary and secondary causes is lacking.ObjectivesTo evaluate underlying causes and predictors of outcome in dogs with CD.AnimalsOne hundred and thirty‐six client‐owned dogs with CD (≥3 weeks duration).MethodsRetrospective review of medical records (Small Animal Clinic, Freie Universität Berlin, Germany, 09/2009‐07/2011). Quantification of final diagnoses and comparison of clinical aspects including disease severity and clinicopathological abnormalities among dogs with clinical remission (either complete [gastrointestinal signs absent] or partial [clinical improvement of gastrointestinal signs and reduced episodes with shortened duration]), and those without recovery.ResultsNinety percent of dogs were diagnosed with a primary enteropathy: inflammatory (71%; of those 66% dietary responsive, 23% idiopathic, 11% antibiotic responsive), infectious (13%), neoplastic (4%), and in one dog each mechanical disease or systemic vasculitis. Secondary causes were diagnosed in 10% of dogs: exocrine pancreatic (6%), endocrine (2%), and in one dog each hepatic, renal, and cardiac disease. In total, 87% of dogs had clinical remission, whereas 13% died or did not respond to treatment: Lack of recovery was frequently recorded for dogs with primary inflammatory (idiopathic) or neoplastic disease and was significantly associated with increased disease severity scores (P = .005), anemia (hematocrit < 40%, P < .001), severe hypoalbuminemia (serum albumin <2.0 g/dL, P = .008), and severe hypocobalaminemia (serum cobalamin concentration <200 pg/mL, P = .006).Conclusions and clinical importanceInflammatory enteropathies and particularly those of dietary origin were the most common causes of CD in dogs. Findings support the usefulness of hematocrit, and serum albumin and cobalamin concentration as prognostic markers in dogs with CD.

“…Canine Coronavirus (CCoV) is an important enteropathogen of dogs, as it has caused many outbreaks (Decaro and Buonavoglia, 2008). CCoV is widespread in canine population, mainly in kennels and shelters, which are overcrowded, according to serological and virological investigations (Naylor et al, 2001;Schulz et al, 2008). Infection with Canine Coronavirus is characterised by high morbidity and low mortality and it is transmitted via the fecal-oral route (Tennant et al, 1991).…”

Dogs and cats play an important role in modern society, enhancing the psychological and physiological well-being of many people. However, there are well-documented health risks associated with human animal interactions. More specifically, enteric pathogens of zoonotic risk which are transmitted by feces of dogs and cats can be grouped as follows: (a) Parasites such as Toxocara canis, T. cati, Ancylostoma sp, Uncinaria sp, Strongyloides stercoralis, Echinococcus granulosus, E. multilocularis and Dipylidium caninum (b) Protozoa including Toxoplasma gondii, Giardia duodenalis and Cryptosporidium spp. (c) Bacteria of the genera Clostridium, Campylobacter, Salmonella, Escherichia, Yersinia and Helicobacter and (d) Viruses mainly Rotaviruses and Coronaviruses. Among them, Salmonella, Campylobacter, Rotaviruses, Toxoplasma gondii, Echinococcus have been reported to be of considerable importance for many countries including Greece. Even though official records of the cases in humans and livestock in Greece continuously decline, cystic echinococcosis is considered to be a serious problem for public health and livestock economy. Regarding other parasites, the overall prevalence of parasitism was 26% in owned shepherd and hunting dogs examined in Serres. Furthermore, seroepidemiological studies revealed the presence of antibodies against T. gondii in a considerable percentage of hospitalized children. Rotaviruses were confirmed as a major cause of acute gastroenteritis in children. Finally, bacterial zoonotic enteropathogens were identified in a notable number of pediatric cases. Most of these zoonoses are associated with the exposure of immunodeficient people or children to pets and/or conditions of poor hygiene. Studies on the presence of all these pathogens in animals are required to identify the extent of problem, to define control strategies and evaluate their effectiveness.

“…Since then, several CCoV outbreaks have been reported worldwide, showing that CCoV is an important enteropathogen of the dog. Serological and virological investigations have demonstrated that CCoV is widespread in dog population, mainly in kennels and animal shelters (Carmichael, 1978;Rimmelzwaan et al, 1991;Tennant et al, 1993;Möstl et al, 1994;Bandai et al, 1999;Naylor et al, 2001b;Yeşilbag et al, 2004;Schulz et al, 2008). CCoV infection is characterised by high morbidity and low mortality, as well as by a typical faecal-oral route of transmission (Tennant et al, 1991).…”
