Blood-borne mycoplasmas, known collectively as hemotropic mycoplasmas or hemoplasmas, are small, pleomorphic, epicellular bacteria that adhere to the host’s red blood cells. They cannot be cultured. They can be detected microscopically in blood smears and, more reliably, through use of PCR assays on whole blood. The hemoplasmas vary in severity of disease caused to the host and most infected an...

Mycoplasma parvum [Eperythrozoon parvum] is the second hemotrophic mycoplasma (hemoplasma) described in pigs. Unlike M. suis, its closest phylogenetic relative, M. parvum, is considered a non-pathogenic bacterium in this host species. Natural infection of a domestic, 6-month-old splenectomized pig with M. parvum strain Indiana is described herein. Light and scanning electron microscopy of the b...

Hemotrophic mycoplasmas and Bartonella species are important pathogens that circulate between cats and invertebrate hosts, occasionally causing diseases in humans. Nevertheless, there are few reports on occurrences of these agents in cats in Brazil. The present study aimed to detect the presence of hemoplasma and Bartonella DNA by means of PCR and sequencing. FIV antigens and anti-FeLV antibodi...

Immune-mediated hemolytic anemia (IMHA) is characterized by the destruction of erythrocytes or sometimes bone marrow erythroid precursors mediated by immunoglobulins (IgG, IgM), with or without complement (C 3). The main objectives of this study were to assess the laboratory test results of IMHA and to investigate its possible underlying causes in cats referring to the Veterinary Teaching Hosp...

The purpose of this study was to evaluate the effect of successful treatment for Bartonella spp, Mycoplasma hemofelis or Candidatus Mycoplasma haemominutum infection of cats on results of diagnostic test results commonly available to veterinary practitioners through commercial diagnostic laboratories. Evidence of infection or exposure to Bartonella spp, M hemofelis or Candidatus M. haemominutum...

Complete physical examinations and biomedical sample collection were performed on 70 free-ranging ring-tailed lemurs (Lemur catta) from three different habitats in the Beza Mahfaly Special Reserve (BMSR), in southern Madagascar, to assess the impact of humans and habitat on lemur health. Lemurs were chemically immobilized with ketamine and diazepam administered via blow darts for concurrent bio...

background :     feline haemotropic mycoplasma are a group of pleomorphic bacteria causing hemolytic anemia along with anorexia, lethargy, dehydration, weight loss and in many cases sudden death in infected animal. however, there is a limited data on the prevalence of these organisms in iranian cats.   methods :    we investigated the presence of feline haemotropic mycoplasma and probable risk ...
