Abstract
Dogs entering shelters can carry gastrointestinal parasites that may pose serious risks to other animals, shelter staff and visitors. Shelters provide an environment that could facilitate the spread of parasitic infections between animals. Nematodes and protozoa that transmit through ingestion or skin penetration are major enteric parasites of concern in shelter settings. Ancylostoma spp., Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis and Dipylidium caninum are the major helminths while Giardia, Cryptosporidium, Isospora spp. and Sarcocystis spp. are the most prevalent protozoan parasites in shelter dogs. The prevalence of gastrointestinal parasites in shelter dogs is typically higher than in owned dogs. A range of cost-effective drugs is available for prevention and control of helminths in shelters, notably fenbendazole, pyrantel, oxantel, and praziquantel. Parasiticide options for protozoan parasites are often cost-prohibitive or limited by a lack of veterinary registration for use in dogs. Environmental control measures reliant upon hygiene and facility management are therefore a mainstay for control and prevention of protozoan parasites in shelters. This philosophy should also extend to helminth control, as integrated parasite control strategies can allow anthelmintics to be used more sparingly and judiciously. The purpose of this article is to comprehensively review the current knowledge on the prevalence of gastrointestinal parasites most commonly found in dogs in shelters, canvass recommended treatment programs in shelter dogs, and to explore the likelihood that parasiticide resistance might emerge in a shelter environment.

da Silva JB, Piva C, Falavigna-Guilherme AL, Rossoni DF, de Ornelas Toledo MJ. Spatial distribution and enteroparasite contamination in peridomiciliar soil and water in the Apucaraninha Indigenous Land, southern Brazil. ENVIRONMENTAL MONITORING AND ASSESSMENT 2016; 188:217. [PMID: 26960764 DOI: 10.1007/s10661-016-5216-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Accepted: 03/01/2016] [Indexed: 06/05/2023]
Abstract
The prevalence and distribution of soil and water samples contaminated with enteroparasites of humans and animals with zoonotic potential (EHAZP) in Apucaraninha Indigenous Land (AIL), southern Brazil, was evaluated. An environmental survey was conducted to evaluate the presence of parasitic forms in peridomiciliary soil and associated variables. Soil samples were collected from 40/293 domiciles (10 domiciles per season), from November 2010 to June 2011, and evaluated by modified methods of Faust et al. and Lutz. Analyses of water from seven consumption sites were also performed. The overall prevalence of soil samples contaminated by EHAZP was 23.8 %. The most prevalent parasitic forms were cyst of Entamoeba spp. and eggs of Ascaris spp. The highest prevalence of contaminated soil samples was observed in winter (31 %). The probability map obtained with geostatistical analyses showed an average of 47 % soil contamination at a distance of approximately 140 m. The parasitological analysis of water did not detect Giardia spp. or Cryptosporidium spp. and showed that all collection points were within the standards of the Brazilian law. However, the microbiological analysis showed the presence of Escherichia coli in 6/7 sampled points. Despite the low level of contamination by EHAZP in peridomiciliar soil and the absence of pathogenic protozoa in water, the AIL soil and water (due to the presence of fecal coliforms) are potential sources of infection for the population, indicating the need for improvements in sanitation and water treatment, in addition periodic treatment of the population with antiparasitic.

FOOD AND ENVIRONMENTAL VIROLOGY 2015; 7:159-163.

Abstract
Hepatitis E virus (HEV) is now accepted as a zoonotic virus, and domestic pigs, wild boars and deer are recognised as natural reservoirs of the pathogen. In this study, 762 animals (wild boars, fallow deer, red deer, sika deer, roe deer and mouflons) originating from the wild and from game enclosures were tested for the presence of HEV RNA by qRT-PCR. HEV RNA was detected in wild boars (96/450), red deer (2/169), roe deer (1/30) and mouflons (5/39). The sequence relationship between HEV isolates from wild boars and domestic pigs or humans indicate a circulation of HEV in the Czech Republic.

Burden of acute gastrointestinal illness in the Metropolitan region, Chile, 2008. Epidemiol Infect 2010; 139:560-71.

Abstract
The purpose of this study was to determine the magnitude and distribution of acute gastrointestinal illness (GI) in the Chilean population, describe its burden and presentation, identify risk factors associated with GI and assess the differences between a 7-day, 15-day and a 30-day recall period in the population-based burden of illness study design. Face-to-face surveys were conducted on 6047 randomly selected residents in the Metropolitan region, Chile (average response rate 75·8%) in 2008. The age-adjusted monthly prevalence of GI was 9·2%. The 7-day recall period provided annual incidence rate estimates about 2·2 times those of the 30-day recall period. Age, occupation, healthcare system, sewer system, antibiotic use and cat ownership were all found to be significant predictors for being a case. This study expands on the discussion of recall bias in retrospective population studies and reports the first population-based burden and distribution of GI estimates in Chile.

Abstract
Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a significant cause of immunosuppression that puts infected individuals at higher risk for developing severe complications from zoonotic infections and other animal-related hazards. The number of people living with HIV grows each year, assuring that veterinary practitioners will have clients and/or employees who are afflicted with HIV/AIDS. Veterinarians need to better understand HIV/AIDS for many reasons: to dispel unfounded beliefs; to address discrimination and liability issues; to educate and protect the health of clients and employees; to help those with HIV/AIDS keep their pets; and to meet legal and professional requirements. To do this, veterinarians must become proactive in learning about HIV/AIDS and in reaching out to pet owners living with HIV/AIDS, as well as the physicians of those individuals. Through discussion on historical and contemporary issues surrounding HIV/AIDS, this article examines why veterinarians need to better understand HIV/AIDS, advocates for more time in the veterinary curriculum on the topic of HIV/AIDS, and provides resources for veterinarians and their clients.

Abstract
Numerous reports exist of the transmission of zoonoses to humans during and after solid-organ and hematopoietic stem cell transplantation. Donor-derived infections of numerous etiologies, including West Nile virus infection, Chagas disease, toxoplasmosis, rabies, lymphocytic choriomeningitis virus infection, and infection due to Brucella species have been reported. Most zoonoses occur as a primary infection after transplantation, and immunocompromised patients are more likely to experience significant morbidity and mortality from these infections. Risks of zoonotic infection in the posttransplantation period could be reduced by patient education. Increased recognition of the risks of zoonoses, as well as the advent of molecular biology-based testing, will potentially augment diagnostic aptitude. Documented zoonotic infection as it affects transplantation will be the primary focus of this review.
