use of real-time quantitative pcr to document successful treatment of mycoplasma haemocanis infection with doxycycline in a dog.an 8-year-old jack russell terrier was diagnosed with hemolytic anemia caused by hemoplasmosis 4 years following splenectomy. quantitative real-time pcr (qpcr) analysis was used initially to confirm infection with mycoplasma haemocanis and subsequently to monitor and direct medical therapy. doxycycline was administered beyond resolution of clinical signs until hemoplasma dna could no longer be detected by qpcr. the dog remained clinically healthy and hemoplasma-negative 8 months following cessat ...201223130935
bile and blood plasma cholesterol as influenced by blood destruction in normal and bile fistula dogs.destruction of large amounts of red cells in normal and bile fistula dogs by means of acetyl phenylhydrazine causes no significant alterations of the blood plasma but there is some decrease in the bile cholesterol. during bartonella canis infection the splenectomized bile fistula dog periodically breaks down large quantities of red cells with slight decrease in the plasma cholesterol and marked decrease in the bile cholesterol. in the periods of blood regeneration following such acute anemias th ...193819870758
bartonella bodies in the blood of a non-splenectomized dog.a non-splenectomized dog, on a vitamin-adequate basal diet, in the course of a plasmapheresis experiment, developed an uncontrollable anemia associated with the presence of bodies in or on the erythrocytes, indistinguishable from the descriptions of bartonella canis. the normal plasma protein level of 7.3 per cent was reduced to 4.1 per cent by diet and the removal of 5354 ml. of whole blood in 33 bleedings. the bartonella infection was transferred to a splenectomized dog by an intravenous injec ...193519870420
the association of bartonella bodies with induced anemia in the dog.on feeding to splenectomized dogs a diet producing black tongue, severe anemia developed associated with the presence of small bodies in or on the erythrocytes. the bodies were morphologically similar to bartonella muris and bartonella canis. the addition of lean beef to the diet, a material prophylactic against its effects, was followed by improvement of the blood levels, the presence of increased numbers of reticulocytes in the circulating blood, and the disappearance of the bodies. when the b ...193519870342
canine mycoplasmas.this review aims to summarise our current understanding of the role of mycoplasmas in domestic dogs. canine mycoplasmology is a small field, with less than 50 publications in the past 40 years. in this time we have gained knowledge about the number of species and have made associations with infections in dogs. however much evidence is still lacking. the importance of all canine mycoplasmas remains unknown, yet certain species are associated with canine anaemia (mycoplasma haemocanis), respirator ...200415894017
'candidatus mycoplasma haematoparvum', a novel small haemotropic mycoplasma from a dog.a novel small haemoplasma was detected following cytological examination of blood smears from a splenectomized dog with haemic neoplasia. the 16s rrna and rnpb genes of the organism were partially sequenced and a phylogenetic tree constructed. the organism was most closely related to the small feline haemoplasma, 'candidatus mycoplasma haemominutum' (94 % 16s rrna gene nucleotide sequence identity; 75 % rnpb) and was only distantly related to mycoplasma haemocanis (78 % 16s rrna gene nucleotide ...200515653848
can we continue research in splenectomized dogs? mycoplasma haemocanis: old problem--new insight.we report the appearance of a mycoplasma haemocanis infection in laboratory dogs, which has been reported previously, yet, never before in europe. outbreak of the disease was triggered by a splenectomy intended to prepare the dogs for a hemorrhagic shock study. the clinical course of the dogs was dramatic including anorexia and hemolytic anemia. treatment included allogeneic transfusion, prednisone, and oxytetracycline. systematic follow-up (n = 12, blood smears, antibody testing and specific po ...200415263824
haemobartonella canis infection in research dogs.during 1970-1972 haemobartonellosis occurred in research canines at 2 widely separated institutions. clinical anemia occurred in a splenectomized dog at a maryland facility, and subsequent screening disclosed an infection rate of 65% in a group of 20 splenectomized subjects. treatment was successful, and the animals were used in research. a research institution in texas encountered a number of dogs with fever (to 106 degrees f) and eosinophilia (to 42%) following minor surgery. blood from affect ...19751242503
candidatus mycoplasma haematoparvum and mycoplasma haemocanis infections in dogs from the united states.mycoplasma haemocanis (mhc) and candidatus mycoplasma haematoparvum (cmhp) have been described in dogs. historically, microscopic visualization of hemotropic mycoplasma spp. has occurred most often in immunocompromised or splenectomized dogs. the aim of this study was to determine the mhc and cmhp prevalences among dogs from the united states. novel 16s rrna and rnasep gene pcr assays were used to amplify hemotropic mycoplasma species dna for genbank sequence alignment. among the study populatio ...201222819621
