(1) Prevalence of Canine Monocytic Ehrlichiosis in Canine Population Across India.[TOP]

Pubmed ID :30242799
Publication Date : //
Canine ehrlichiosis is a very important emerging disease in India. This study is the first attempt screening a large number of canines in India for the detection of canine monocytic ehrlichiosis. In the present study, 510 blood samples of dogs were screened for the presence of Ehrlichia canis and other variants of Anaplasmataceae family by serological and molecular methods.Out of the 510 serum samples, 293 (57.5%) cases were found positive for the presence of E. canis antibodies through enzyme-linked immunosorbent assay (ELISA). Furthermore, and 45 (8.8%) and 1 (0.2%) specimens were positive for E. canis and A. platys, respectively, based on the polymerase chain reaction (PCR). In the clinical samples of E. canis, the minimum detection limit for PCR was9 ng. In the immunofluorescence assay (IFA), the positive blood samples showed comparable results with those obtained from the commercially available dot ELISA kit (giving equivalent IFA titer). The results of sequencing were compared with other reported isolates in various regions of the world, and a phylogenetic relationship was established. The 16S rRNA region that was amplified and sequenced for E. canis and A. platys was highly conserved and so was another Vir B9 region.

(2) Retrospective Evaluation of Anti-Toxoplasma gondii Antibody Among First Trimester Pregnant Women Admitted to Nenehatun Maternity Hospital between 2013-2017 in Erzurum.[TOP]

Pubmed ID :30070642
Publication Date : //
Echinococcus granulosus, the etiological agent of cystic echinococcosis (CE) in humans and livestock, is a widely distributed zoonotic pathogen tapeworm. The infection is transmitted to humans by the ingestion of E. granulosus eggs released in the feces of definitive hosts such as dogs. The larval stage of the parasite develops a slowly enlarging cyst in the visceral organs, particularly in the liver and/or lung. The aim of the present study was to evaluate the diagnostic value of an immunochromatographic test (ICT) for CE.

(3) Comparative performance of reference laboratory tests and in-clinic tests for Giardia in canine feces.[TOP]

Pubmed ID :30068364
Publication Date : //
We examined the performance of four in-clinic Giardia diagnostic tests by comparing results to three laboratory methods for detection of Giardia. A set of 177 fecal samples originally submitted to a commercial laboratory by veterinarians for routine ova and parasite (O&P) testing was used. Specimens were examined by direct immunofluorescence assay (DFA) for presence of Giardia cysts which served as the gold standard. Fecal samples were tested using a Giardia-specific cyst wall antigen microtiter plate format enzyme-linked immunosorbent assay (ELISA) and each of the in-clinic assays adhering to the package insert for each kit.

(4) Validation of a human angiopoietin-2 ELISA for measurement of angiopoietin-2 concentrations in canine plasma samples and supernatant of primary canine aortic endothelial cell cultures.[TOP]

Pubmed ID :30058854
Publication Date : //
OBJECTIVE To assess 2 human ELISA kits for measurement of angiopoietin-1 and -2 concentrations in canine plasma samples, determine whether plasma angiopoeitin-2 concentration differed between septic and healthy dogs, and determine the effect of tumor necrosis factor-α (TNF-α) stimulation on angiopoeitin-2 release from primary canine aortic endothelial cells (pCAECs) in vitro. ANIMALS 10 healthy dogs and 10 septic dogs. PROCEDURES Human angiopoietin-1 and -2 ELISAs were used to detect recombinant canine angiopoietins-1 and -2 in canine plasma samples. The angiopoietin-2 ELISA was further validated by use of plasma samples from healthy and septic dogs and supernatants of pCAEC cultures. Associations between plasma angiopoeitin-2 and C-reactive protein (CRP) concentrations were examined. RESULTS Angiopoeitin-2 but not angiopoeitin-1 was detected in canine plasma samples by the respective ELISAs. The angiopoeitin-2 ELISA had excellent dilutional linearity, parallelism, accuracy, precision, and reproducibility for measurements in canine plasma samples and pCAEC supernatants. Plasma angiopoeitin-2 concentration was significantly higher in septic dogs (median, 25.5 ng/mL) than in healthy dogs (median, 6.7 ng/mL) and was positively correlated with plasma CRP concentration (R = 0.60). Stimulation of pCAECs with TNF-α resulted in a significant increase in supernatant angiopoietin-2 concentration. CONCLUSIONS AND CLINICAL RELEVANCE The tested human angiopoietin-2 ELISA kit was useful for measuring angiopoietin-2 concentrations in canine plasma samples and pCAEC supernatants. Sepsis appeared to increase angiopoietin-2 concentration in dogs in vivo, whereas TNF-α stimulation caused release of angiopoietin-2 from pCAECs in vitro. These findings support the use of angiopoietin-2 as a marker of endothelial cell activation and inflammation in dogs.

(5) Cyclooxygenase inhibitors potentiate receptor tyrosine kinase therapies in bladder cancer cells in vitro.[TOP]

Pubmed ID :29942116
Publication Date : //
Receptor tyrosine kinase inhibitors (RTKIs) are used as targeted therapies for patients diagnosed with cancer with highly expressed receptor tyrosine kinases (RTKs), including the platelet-derived growth factor receptor (PDGFR) and c-Kit receptor. Resistance to targeted therapies is partially due to the activation of alternative pro-survival signaling pathways, including cyclooxygenase (COX)-2. In this study, we validated the effects of two RTKIs, axitinib and AB1010, in combination with COX inhibitors on the V-akt murine thymoma oncogene homolog 1 (Akt) and COX-2 signaling pathways in bladder cancer cells.

(7) Comparison of six commercial antigen kits for detection of Dirofilaria immitis infections in canines with necropsy-confirmed heartworm status.[TOP]

Pubmed ID :29657005
Publication Date : //
Patient-side test kits for detecting antigenemia in dogs associated with sexually mature female heartworms (Dirofilaria immitis) have been available for three decades, and these tests are continually updated and improved. To define the sensitivity (Se) and specificity (Sp) of contemporary antigen detection tests against cardiopulmonary D. immitis burden, we evaluated five patient-side kits-Anigen Rapid One Step (Bio note), SNAP 4Dx Plus Test Kit (IDEXX), WITNESS Heartworm Canine Heartworm Antigen Test Kit (Zoetis), VetScan Canine Heartworm Rapid Test (Abaxis), and Solo Step CH Canine Heartworm Antigen Test (Heska), and one microplate ELISA (DiroCHEK; Zoetis), using archived canine sera divided into five subclasses of female worms (0, 1-5, 6-20, 21-40, and >40). The patient-side tests were performed once, side-by-side according to each manufacturer's protocol by personnel blinded to the D. immitis status of each dog. The overall Se and Sp of the patient-side kits was ≥97.5 and =94.0%, respectively. For samples from dogs with 1-5, 6-20, and 21-40 D. immitis, the Se was between 96 and 100%, with a slight increase in Se in dogs with ≥41 worms. The agreement between tests for all subclasses of D. immitis burden was between 99 and 100%. The Se and Sp for the ELISA compared with the necropsy results of dogs was 99 and 96%, respectively. Agreement between each patient-side test and the ELISA was between 97 and 100%. All commercially available tests can give practitioners excellent patient-side information, allowing them to make informed decisions on the need for additional diagnostic work-up before instituting new or continuing D. immitis prophylaxis.

(8) Prevalence of Neospora spp. in donkeys in China.[TOP]

Pubmed ID :29557777
Publication Date : //
This study was conducted to detect specific anti-Neospora antibodies using a commercial competitive-inhibition ELISA kit, and to evaluate the risk factors for Neospora spp. infection. Out of a total of 2,228 donkey sera collected in three provinces in China, 211 (9.5%) were found to be positive for anti-Neospora antibodies. Statistical analysis revealed that age (p = 0.019, OR = 1.62, 95%CI: 1.08-2.44), feeding status (p < 0.001, OR = 3.79, 95%CI: 2.65-5.43), miscarriage history (p = 0.006, OR = 2.56, 95%CI: 1.27-4.01), and contact with dogs (p < 0.001, OR = 2.69, 95%CI: 1.86-3.88) were significant risk factors for Neospora spp. infection. This is the first evidence of Neospora infection in donkeys in China.

(9) Canine Monocytic Ehrlichiosis among working dogs of organised kennels in India: A comprehensive analyses of clinico-pathology, serological and molecular epidemiological approach.[TOP]

Pubmed ID :29254723
Publication Date : //
Canine Monocytic Ehrlichiosis (CME) is a serious tick-borne rickettsial disease affecting canine populations globally. Besides few reports from stray and pet dogs from localised geographical regions (cities/towns/small states), a comprehensive study on prevalence of Ehrlichia canis (E. canis) among working dogs from different geo-climatic zones of India was pertinently lacking. Study of CME among these dog populations was thus carried out, encompassing clinical aspects and different diagnostic methodologies viz., microscopy, serology and molecular biology. During the two-year study period, clinical specimens from 225 cases suspected of canine ehrlichiosis were examined for clinical pathology and presence of the haemoparasites. Overall prevalence of ehrlichiosis by microscopic examination, commercial dot-ELISA kit and nested PCR assay was estimated to be 1.3%, 19.1% and 5.8%, respectively, which were found to be statistically significant by McNemar Chi squared test (p<0.05). It was also observed that possibly due to widespread use of doxycycline therapy in field, CME presently does not remain a potential threat which it uses to pose earlier. However, concurrent infections of E. canis and Babesia gibsoni were found to be mostly fatal. Keeping in view of high number of apparently healthy dogs (24) out of total positive cases (46) observed during the study, it is recommended that prevalence studies on CME should also involve screening of apparently healthy dogs. Phylogenetic analysis carried on partial sequencing of 16S rRNA of E. canis strains revealed that all of the Indian strains clustered in a single clade with other E. canis species from India and rest of the world. Molecular divergence was observed among the sequences of Brazilian and American isolates which were also included in the present study. These findings have thus opened a new paradigm for planning of pragmatic control strategies against CME.

(10) Seroprevalence of toxoplasmosis and risk factors of Toxoplasma gondii infection among pregnant women in Sri Lanka: a cross sectional study.[TOP]

Pubmed ID :29202747
Publication Date : //
Toxoplasma gondii is an intracellular protozoan infecting humans and animals. Infection in adults usually causes mild disease but greater importance lies in preventing transplacental transmission which can cause major foetal anomalies and is vital to identify infection in pregnancy. Research on this regard in Sri Lanka is scarce and would be beneficial in developing antenatal care strategies for improved foetal outcome.
