“…It has been reported that A. phagocytophilum isolates vary with respect to pathogenicity and that some isolates display zoonotic potential (Overzier et al 2013). Moreover, in the present study, nucleotide sequence of one of the dogs presented 99% similarity with isolates derived from a human patient in USA.…”

958RESUMO.-[Importante frequência da infecção por Anaplasma phagocytophilum em uma população de cães domiciliados em área urbanizada no sudeste do Brasil.] Anaplasma phagocytophilum é responsável pela anaplasmose granulocítica, doença que acomete seres--humanos e várias espécies de animais. O objetivo do presente estudo foi determinar a prevalência de cães acometidos por A. phagocytophlium em uma área residencial de Belo Horizonte, MG, Brasil. Sessenta e dois cães foram submetidos a testes sorológicos (reação de imunofluorescência indireta -IFAT) e moleculares (PCR). Anticorpos anti-A. phagocytophilum foram detectados em 43,8% dos cães. Sete cães (10,9%) foram positivos no PCR para o gene msp4 de A. phagocytophilum, seis para o gene msp2/ p44 A. phagocytophilum e quatro para a região 16S rRNA de Anaplasmataceae granulocíticas. Esse estudo confirma a frequência relativamente alta da infecção por A. phagocytophilum em uma população de cães domiciliados em área urbanizada no sudeste do Brasil e destaca a necessidade de pesquisas para determinar o papel do carrapato Rhipicephalus sanguineus sensu lato na transmissão desse microrganismo para cães de áreas urbanas brasileiras.

“…The prevalence for A. phagocytophilum was 34.2%. It is worth noting that the prevalence of A. phagocytophilum in roe deer from Europe presents high variability depending on the country; while only 5.1% of roe deer were positive in Italy (Carpi et al 2009), the prevalence in the Bavarian region (Germany), where ticks and roe deer are in close contact, raised to 98.9% (Overzier et al 2013). In Spain, only two studies have been performed in roe deer up-to-now.…”

In order to provide up-to-date information about the prevalence of infectious and parasitic agents in Spanish roe deer (Capreolus capreolus), samples from 93 animals hunted from January 2013 to April 2015 were collected and analysed by parasitological, serological and molecular techniques. Sampled animals came from four roe deer populations corresponding to Oceanic, Continental, Mediterranean and Mountainous ecosystems of Spain. Data regarding sex, age and year were also considered. A high percentage of roe deer (95.7%) resulted positive for at least one agent. Sarcocystis spp. was the most frequently diagnosed genus (88.8%), followed by gastrointestinal nematodes (62.9%) and Schmallenberg virus (53.5%). Varestrongylus capreoli (38%), Anaplasma phagocitophylum (34.2%), Eimeria spp. (29.2%), Toxoplasma gondii (25%) and Cephenemyia stimulator (23.8%) displayed medium prevalences and, finally low percentages were registered for Moniezia spp. (6.7%), Dictyocaulus noerneri (2.4%) and Mycobacterium avium subsp. paratuberculosis (1.5%). No infections by Neospora caninum, Bovine herpesvirus, pestivirus or Coxiella burnetii were found. Climate was significantly associated with the prevalence of T. gondii, C. stimulator and A. phagocitophylum, with higher prevalences in animals from Oceanic and Mediterranean areas. Our results suggest that infections affecting Spanish roe deer, especially those of parasitic aetiology, represent one of the causes of the descent in the abundance of this ungulate in the last years. Moreover, the high prevalence of zoonotic agents such as T. gondii and A. phagocitophylum could also have a great relevance in the environmental and/or Public Health. ARTICLE HISTORY

“…Natural infection with A. phagocytophilum has been reported in wild deer, and these animals are considered reservoirs in Europe, Asia and North America (revised by Stuen et al (2013)). Pathogenic and apathogenic genetic variants have been found in these animals SILAGHI et al, 2011;OVERZIER et al, 2013).…”

Post-mortem hemoparasite detection in free-living Brazilian brown brocket deer (Mazama gouazoubira, Fischer 1814) AbstractTick-borne infections can result in serious health problems for wild ruminants, and some of these infectious agents can be considered zoonosis. The aim of the present study was the post-mortem detection of hemoparasites in free-living Mazama gouazoubira from Minas Gerais state, Brazil. The deer samples consisted of free-living M. gouazoubira (n = 9) individuals that died after capture. Necropsy examinations of the carcasses were performed to search for macroscopic alterations. Organ samples were collected for subsequent imprint slides, and nested PCR assays were performed to detect hemoparasite species. Imprint slide assays from four deer showed erythrocytes infected with Piroplasmida small trophozoites, and A. marginale corpuscles were observed in erythrocytes from two animals. A. marginale and trophozoite co-infections occurred in two deer. A nested PCR analysis of the organs showed that six of the nine samples were positive for Theileria sp., five were positive for A. phagocytophilum and three were positive for A. marginale, with co-infection occurring in four deer. The results of the present study demonstrate that post-mortem diagnostics using imprint slides and molecular assays are an effective method for detecting hemoparasites in organs.
