Hemotropic Mycoplasmas (Hemoplasmas) in Free-Ranging Azara's Agoutis (Dasyprocta azarae) from an Urban Area of Southern Brazil.

Hemotropic mycoplasmas (hemoplasmas) are opportunistic bacteria that attach to the erythrocyte surface, causing infectious anemia in several mammalian species, including rodents. Studies surveying native Azara's agoutis (Dasyprocta azarae) in Brazil are lacking. Accordingly, the present study aimed to assess hemoplasmas infection in free-ranging agoutis from an urban environmental conservation area in Curitiba, southern Brazil.

A Primer for the Evaluation of Bone Marrow.

The traditional role of cytologic and histologic evaluation of bone marrow remains important in understanding diseases and conditions that affect this tissue. It is only through correlation of historical and clinical findings with hematologic, bone marrow, and other ancillary data that an accurate diagnosis can be made. Thus, the clinician is an essential link in helping establish a correct diagnosis.

Complete Blood Counts and Blood Smear Analyses in 312 Diabetic Dogs (2007-2017).

Diabetes mellitus is a common endocrinopathy in dogs that has been associated with various biochemical changes and comorbid diseases, but hematologic abnormalities have been rarely reported. The aim of this retrospective study was to evaluate complete blood count and blood smear alterations and to describe their relationship with, and incidence of comorbid diseases in, diabetic dogs. Three-hundred twelve diabetic dogs, 286 dogs diagnosed with systemic, nondiabetic illnesses, and 506 healthy dogs were identified during the study period.

Atypical multiple myeloma in 3 young dogs.

Three dogs under 12 months old were diagnosed with atypical multiple myeloma (MM), having an aggressive multifocal anaplastic round cell sarcoma in bone marrow, viscera, and/or peripheral blood, which were confirmed by cytology and immunohistochemistry to be of plasma cell origin. The intramedullary sarcomas caused myelophthisis, osteolysis, and hypercalcemia. Complete or free light chain monoclonal gammopathy in the serum and/or urine was demonstrated by protein electrophoresis and immunofixation.

Hemophagocytic syndrome associated with large granular lymphoma in an adult dog.

Hemophagocytic syndrome (HPS) is a rare disorder characterized by dysregulation of the immune response resulting in uncontrolled activation of macrophages with exacerbated phagocytosis of host cells. In dogs, the criteria for diagnosis include the presence of pancytopenia or bicytopenia in the peripheral blood and >2% hemophagocytic macrophages in bone marrow aspirates. When HPS is associated with lymphoma, it is called lymphoma-associated hemophagocytic syndrome (LAHS).

A case of acute monocytic leukemia (AMoL or AML-M5) in an adult FeLV/FIV-positive cat.

A 7-year-old castrated male domestic shorthair cat was presented for evaluation of decreased appetite and respiratory signs. A CBC run on presentation revealed severe nonregenerative anemia, thrombocytopenia, and leukocytosis characterized by a prominent population of blasts, having morphologic features suggestive of a monocytic lineage. The cat tested positive for FIV, FeLV, Mycoplasma haemominutum, and only mild abnormalities were identified on the chemistry panel.

Genomic profile of Brazilian methicillin-resistant Staphylococcus aureus resembles clones dispersed worldwide.

Purpose: Comparative genomic analysis of strains may help us to better understand the wide diversity of their genetic profiles. The aim of this study was to analyse the genomic features of the resistome and virulome of Brazilian first methicillin-resistant Staphylococcus aureus (MRSA) isolates and their relationship to other Brazilian and international MRSA strains.

Methodology: The whole genomes of three MRSA strains previously isolated in Vitória da Conquista were sequenced, assembled, annotated and compared with other MRSA genomes.

RNA-Seq based transcriptome of whole blood from immunocompetent pigs (Sus scrofa) experimentally infected with Mycoplasma suis strain Illinois.

Pigs are popular animal models in biomedical research. RNA-Seq is becoming the predominant tool to investigate transcriptional changes of the pig's response to infection. The high sensitivity of this tool requires a strict control of the study design beginning with the selection of healthy animals to provide accurate interpretation of research data.

A cross sectional study evaluating the prevalence of Coxiella burnetii, potential risk factors for infection, and agreement between diagnostic methods in goats in Indiana.

Coxiella burnetii is the etiologic agent of the zoonotic disease Q fever and is considered to be endemic in domestic ruminants. Small ruminants in particular are important reservoirs for human infection. Serologic and molecular methods are both available for diagnosis of infection with C.

Occurrence and identification of hemotropic mycoplasmas (Hemoplasmas) in free ranging and laboratory rats (Rattus norvegicus) from two Brazilian zoos.

Background: Hemotropic mycoplasmas (hemoplasmas), bacteria belonging to the class Mollicutes, are obligatory red blood cell pathogens of a variety of animal species. They may cause acute anemia that is life-threatening or chronic disease that is clinically silent, but may interfere with results of experimental studies when using infected animals. Since these bacteria cannot be cultivated, molecular techniques are the gold standard for diagnosing an infection, investigating its prevalence, and describing new species.

Hemoplasma prevalence and hematological abnormalities associated with infection in three different cat populations from Southern Brazil.

Three hemoplasma species are recognized in domestic cats: Mycoplasma haemofelis, 'Candidatus Mycoplasma haemominutum' and 'Candidatus Mycoplasma turicensis'. We report the prevalence and hematological abnormalities of hemoplasma infection in 369 domestic cats from three different populations (blood donors, hospitalized cats and shelter cats) from Southern Brazil. Complete blood counts were performed at the time of blood collection, and DNA was extracted and tested by conventional PCR for each hemoplasma species.
