Nghiên cứu được thực hiện nhằm xác định những đặc điểm và phương pháp chẩn đoán hiệu quả bệnh Ehrlichiosis do Ehrlichia canis (E. canis) gây ra trên chó. Tổng số 151 mẫu máu thu thập từ con chó nghi nhiễm E. canis. Mẫu bằng kit canis-Ab, đồng thời kiểm tra sự diện của phôi dâu tế bào bạch cầu nhuộm tiêu bản đếm lượng tiểu cầu. Kết cho thấy có 103/151 (68,21%) dương tính với canis-Ab. Tình trạng...

Brucella canis infection is an important cause of late-term abortion in pregnant bitches. The pathophysiological mechanisms leading to B. canis-induced abortion are unknown, but heavily infected trophoblasts are consistently observed. As trophoblasts responses to other pathogens contribute to placental inflammation leading to abortion, the aim of the present study was to characterize the cytoki...

Background Brucella canis is a pathogenic bacterium that causes brucellosis in dogs, and its zoonotic potential has been increasing in recent years. B. canis is a rare source of human brucellosis in China, where Brucella melitensis has been the major pathogen associated with human brucellosis outbreaks. In late 2011, a case of a B. canis infection was detected in a human patient in Zhejiang Pro...

Parasitemia with a large Babesia species was identified in two domestic cats from Israel. One cat, also coinfected with feline immunodeficiency virus and "Candidatus Mycoplasma haemominutum," had profound icterus and anemia which resolved after therapy, whereas a second cat was an asymptomatic carrier. Amplification and sequencing of the 18S rRNA gene, followed by phylogenetic analyses, indicat...

conclusions through these results, the applicability of the used extracts in the control of eggs and/or larvae of t. canis and a. caninum is suggested. however, it is worth mentioning that further studies should be performed with the species e. edulis, m. glomerata and m. laevigata, using different extracts, new concentrations, and in vivo studies, in order to ensure further clarification on th...

Canine babesiosis has recently been recognized as an emerging infectious disease of dogs in North America. We sought to develop a seminested PCR to detect and differentiate Babesia gibsoni (Asian genotype), B. canis subsp. vogeli, B. canis subsp. canis, and B. canis subsp. rossi DNA in canine blood samples. An outer primer pair was designed to amplify an approximately 340-bp fragment of the 18S...

The immune response expressed by IgG antibodies in BALB/c mice experimentally infected with Toxocara canis, was studied with the aim of verifying the possible in vivo cross-reactivity between antigens of T. canis and other parasites (Ascaris suum, Taenia crassiceps, Schistosoma mansoni, Strongyloides venezuelensis and Toxoplasma gondii). Experiments included three groups of mice: one infected o...

The genus Babesia comprises protozoa that cause diseases known as babesiosis. Dogs are commonly affected by Babesia canis or Babesia gibsoni. Babesia canis is divided into the subspecies Babesia canis canis, Babesia canis vogeli and Babesia canis rossi. Among these, Babesia canis vogeli predominates in Brazil. The objective of this study was to conduct a phylogenetic analysis on Babesia isolate...

Aim: To determine the seroprevalence of vector(tick)-borne Babesia canis, Babesia gibsoni, Ehrlichia canis and Borrelia burgdorferi and mosquito-borne Dirofilaria immitis in naturally exposed pet, working, and street dogs in Assam, India. Materials and Methods: Seroprevalence of B. canis and B. gibsoni was determined using Indirect Fluorescent Antibody Test (IFAT) kit and for D. immitis, E. can...

We aimed to investigate IgG antibody levels specific to Toxocara canis (T. canis), a parasite which subsists in dog's intestine, on serum samples obtained from patients with chronic urticaria (CU) to evaluate effective risk in CU etiopathogenesis. In this study, 73 patients diagnosed with CU and 109 healthy individuals as control group, were included. Various factors such as sex, age, education...
