There is a high mortality rate in patients with systemic inflammatory response syndrome (SIRS) or sepsis. Therefore, an early diagnosis and prognostic assessment important for optimal therapeutic intervention. The objective of the study was to evaluate if baseline values changes serum C-reactive protein (CRP) might predict survival dogs SIRS sepsis.Prospective study; July 2004 2005.Small Animal Clinic, Berlin, Clinic Small Medicine, Munich.Sixty-one dogs.For CRP analysis blood drawn on day...

Tick-borne diseases are a major health risk for humans and dogs. In addition to collection analysis of questing ticks, host-associated ticks the presence pathogens is valuable method gain insight into transmission patterns tick-borne diseases.Ticks were collected from dogs living in Berlin/Brandenburg area. The three tick species Ixodes ricinus, hexagonus Dermacentor reticulatus examined Babesia spp., Borrelia Rickettsia spp. Anaplasmataceae. Conventional PCR followed by sequencing was used...

Abstract Immune thrombocytopenia (ITP) is the most common acquired primary hemostatic disorder in dogs. less commonly affects cats but an important cause of mortality and treatment‐associated morbidity both species. remains a diagnosis exclusion for which diagnostic guidelines are lacking. Primary, or non‐associative, ITP refers to autoimmune platelet destruction. Secondary, associative, arises response underlying disease trigger. However, evidence comorbidities serve as triggers has not...

During a 6-year period, primary (idiopathic) immune-mediated thrombocytopenia was retrospectively evaluated in 30 dogs. Ages of the dogs ranged from 3 months to 10 years (median 4 years); female were markedly overrepresented with 73%. Clinical examination revealed hemorrhages 70% Platelet counts 0 111,000/μL 8000/μL); 77% had platelet <30,000/μL. Seventeen anemic (hematocrit 9% 36%; median 31%).

Abstract Methicillin-resistant Staphylocoocus aureus (MRSA) harboring mecALGA251 has been isolated from humans and ruminants. Database screening identified this MRSA variant in cats, dogs, a guinea pig Germany during 2008–2011. The novel is not restricted to ruminants or humans, contact with companion animals might pose zoonotic risk.

Sepsis is still a major cause of death in both human and veterinary medicine. Early diagnosis essential for appropriate treatment. Identification patients at risk developing sepsis already possible medicine through the measurement plasma interleukin-6 (IL-6) levels.

ABSTRACT “ Candidatus Neoehrlichia mikurensis” ( Anaplasmataceae ) is an emerging pathogen transmitted by Ixodes ticks. Conventional PCR and the newly developed high-resolution melt were used to detect discriminate Anaplasma phagocytophilum . Both bacterial species frequently found in ricinus hexagonus but virtually absent from Dermacentor reticulatus In rodents, N. was significantly more prevalent than A. , whereas cats, only found.
