The objective of this study was to determine the prevalence, associated factors, and geographic areas of D. immitis in dogs in the city of Sousa, Paraíba, Northeast Brazil. A total of 320 dogs were selected and evaluated, 160 domiciled and 160 wandering, from the 32 districts of the city. Clinical examination, blood collection, and epidemiological data retrieval were performed for each animal. The sanitation conditions of the environment were visually observed at the time of evaluation. Three methods were used to investigate the morphometric diagnosis of microfilariae: capillary blood smear (ESC), peripheral blood smear (ESP), and modified Knott test. The data were subjected to univariate and multivariate statistics for the observation of risk factors and qualitative assessment of the examinations. Of the 17.5% (56/320) of animals testing positive for D. immitis, 25% (40/160) were wandering and 10% (16/160) were domiciled dogs. Positive dogs were found in 24 of the 32 neighborhoods evaluated, with Angelim and Doutor Zezé having the highest percentages of 1.56% (5/320) each. Only the categories of cardiac alterations (OR 6.231 [1,539-25,236]) and stray dogs (OR 2.463 [1,281-4,735]) demonstrated potential risk factors for infection. Of the 56 positive animals, 28 were positive in the three tests, and another 28 showed variance between methods and/or between prepared slides. No other filaridae were observed. The city of Sousa is considered to have a significant prevalence of infection by D. immitis, and forms of control and prophylaxis are required to reduce the risks of transmission to animals, as well as to humans.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67516288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighty cows were followed from -60 to 60 days relative to calving and hoof injuries were reported on days -60, 7 and 60. Locomotion score (LS), body condition score (BCS), the concentrations of non-esterified fatty acids, β-hydroxybutyrate, glucose, cholesterol, albumin, total protein, blood urea nitrogen (BUN), calcium, phosphorus, and magnesium, and the activity of aspartate aminotransferase were determined at days -42, -21, -7, 0, 7, 21 and 42. The McNemar and Chi-square tests were used to compare frequencies of lameness and hoof injuries over time and to verify the associations between lameness, BCS, hoof injuries, and metabolic disorders. Two-way repeated measures ANOVA was used considering groups (non-lame × lame cows) and variations of BCS and metabolites over time. Lameness and hoof injuries increased between days -60 (20% and 66.3%) and 60 (44.7% and 98.6%). Excessive postpartum loss of BCS (P=0.017) and subclinical hypocalcemia (P=0.012) were associated with lameness on day 60. In general, the metabolic profile did not differ between lame and non-lame cows but cholesterol, albumin, BUN and magnesium concentrations were higher in non-lame cows. The postpartum decrease in BCS can affect the occurrence of lameness, and the metabolic profile of lame cows shows little difference from that of non-lame cows.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67518781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large extensions of agroforestry systems, where cocoa is grown under the shade of native trees, contribute to wildlife conservation in southern Bahia, Brazil. However, this system can increase contact between species of the native fauna and domestic dogs, which are frequently taken to the fields by rural workers. The aims of this study were to investigate the presence of domestic dogs inside cocoa agroforestry systems and the occurrence of helminths in dogs from cocoa farms near two protected areas: the Una Biological Reserve (REBIO-Una) and the Serra das Lontras National Park in Una, Bahia. We also investigated general characteristics of the dogs such as age, sex, breed, feeding frequency, vaccination, deworming and others, and evaluated possible risks of wildlife and human contamination by the domestic dog parasites. Camera traps were set up on eight cocoa agroforestry systems and three adjacent forest fragments. For parasitological investigation, fecal samples were collected from domestic dogs that lived on the eight cocoa farms. A total of 539 photos of 12 mammals were registered, of which 15% were of domestic dogs. The parasitological research was carried out with fecal samples from 32 of the 39 dogs that lived in the cocoa farms. We found one genus of cestode, Dipylidium sp. (7.7%), and five genera of nematodes, Ancylostoma sp. (80.7%), Strongyloides sp. (38.4%), Toxocara sp. (30.7%), Spirocerca sp. (15.4%) and Trichuris sp. (11.5%). Regarding animal care, all dogs were in poor body condition, 49% were fed twice a day, 90% defecated in the forest or cocoa agroforestry systems, only 33% were periodically dewormed, 64% were vaccinated against rabies in less than 12 months, and only one dog was vaccinated against other viruses. The results showed that domestic dogs share the same environment as wild animals yet lack some basic health care, increasing the possibility of parasitic transmission between domestic dogs, wildlife and humans from environmental contamination. We highlight the need for responsible pet ownership and the monitoring the health of wild animals and the human population living in this region.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67514235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Birds are relevant in the life cycle and epidemiology of protozoa due to the wide variety of bird species, feeding and migratory habits. The aim of this study was the molecular detection of T. gondii, N. caninum and Sarcocystis spp. in several species of naturally infected birds. Therefore, samples of brain and heart tissue were collected from birds received and necropsied at the Central Laboratory for the Diagnosis of Avian Pathologies (LCDPA), undergoing DNA extraction and amplification by the polymerase chain reaction (PCR) of the 18S rRNA gene to Sarcocystis spp., NC5 gene for N. caninum and repetitive gene 529 base pairs for T. gondii. N. caninum was detected in two birds (02/65, 3.07%), in a brain sample of Rupornis magnisrostris (accession number: ON182081, 267pb) and in a brain and heart sample of Dendrocygna bicolor (accession number: ON211312, 267pb). DNA of the genus Sarcocystis was detected in three birds (03/65, 4.62%), and in the genetic sequencing Sarcocystis spp. (accession number: MW463929) in brain of Nymphicus hollandicus and Sarcocystis speeri (accession number: MW464125) in brain and heart of Amazona aestiva. Phylogenetic analysis revealed that Sarcocystis spp. formed a clade with Sarcocystis spp. that use skunk (Didelphis aurita) as definitive host and Sarcocystis falcatula that use Moluccan loris (Trichoglossus moluccanus) as intermediate host. S. speeri formed a clade with S. speeri that used Mus musculus as an experimental intermediate host and formed a clade with Sarcocystis columbae, Sarcocystis corvusi, Sarcocystis halieti and Sarcocystis sp. that affect bird species. T. gondii DNA was not detected in any tissue. This is the first report of DNA detection of N. caninum, Sarcocystis spp. and S. speeri in tissue samples for these bird species extending the list of intermediate hosts.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"10 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67515633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of five herds, from which 72 cows (120 mammary quarters - MQ) were diagnosed with S. aureus subclinical mastitis, were included in this study. Cows were randomly allocated to one of three treatment groups: a) Control (no treatment); b) ATB (antibiotic therapy); and c) ATB+VAC (antibiotic therapy plus vaccination against S. aureus). Intramammary treatment consisted of twice-daily infusion of ampicillin 75mg + cloxacillin 200mg, for 5 days. Parenteral treatment was done by injection of a single dose (7.5mg/kg) of enrofloxacin, on the first day of the treatment protocol. Vaccinated cows received three doses of a commercial vaccine 14 days before treatment (d-14), on the first day of treatment protocol (d1), and 14 days after the treatment protocol (d+14). Non-treated cows had a lower cure rate (0.06) than cows treated with ATB (0.84) and ATB+VAC (0.85). No difference in cure rate was observed between cows treated with ATB and ATB+VAC. On the other hand, vaccinated cows had lower somatic cell count (SCC) after 28 days of the treatment protocols (4.76 log10) than non-treated cows (5.37 log10). In conclusion, treatment with intramammary ampicillin and cloxacillin, associated with intramuscular enrofloxacin presented a high cure rate for SCM caused by S. aureus during lactation. The use of vaccination against S. aureus in association with antibiotic therapy did not increase the cure rate of MQ during lactation, but it was effective in reducing the SCC when compared to non-treated MQ. Although to ensure that the decrease of the SCC in ATB+VAC group was associated with the vaccination, the study should have included an additional group of only vaccinated cows, without antimicrobial therapy, with was not done in the present study, and therefore is one of the limitations of the experimental protocol used.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67515998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although various heart diseases have different pathophysiologies, many morphological and hemodynamic changes can predispose patients to arrhythmias. The presence of arrhythmias can worsen the underlying heart disease and predispose patients to develop new alterations, making arrhythmia detection important for establishing adequate therapeutic protocols and a better prognosis. The present study aimed to determine the arrhythmias most frequently found in dogs treated at the Cardiology and Respiratory Diseases Service (SCDR) of the Small Animals Sector of the Veterinary Hospital of the Federal Rural University of Rio de Janeiro (UFRRJ), during the period from January to 2014 to December 2017, relating them to sex, age group, size, and the presence or absence of heart disease. A total of 586 medical records of dogs treated with SCDR-UFRRJ were retrospectively evaluated. Of these, 15.4% had arrhythmias, 95.6% had diagnoses of heart disease, 61.1% (55/90) were diagnosed with mitral valve disease, and 27.8% (25/90) had dilated cardiomyopathies. The most frequent rhythm disturbances were premature ventricular complexes associated with chronic degenerative mitral valve disease or dilated cardiomyopathy. Statistical analysis confirmed the risk of a cardiac patient developing rhythm or conduction alterations (OR, 4.46; p = 0.0003). In conclusion, the pathophysiology of heart failure can lead to the development of rhythm and conduction disorders.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67518587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the etiology of high mortality in Chukar partridges suspected of infection with these agents was investigated pathologically and molecularly. Twelve healthy partridges during the laying period and 30 partridges that died due to disease and were included in the study. In blood analysis, increased levels of WBC, NEU, LYM, MONO, EO and BASO suggesting bacterial and/or parasitic infection; decreased levels of HGB, MCH and MCHC, which are markers of anemia; and increased AST and LDH levels, which are important for liver degenerations. In the liver, which is one of the most pathologically affected organs, multifocal necrosis foci that sometimes merge with each other and spread to large areas, and severe fibrino-necrotic typhlitis were detected. There was amyloid deposition in the space of Disse and vascular sinuses in the liver. PAS positive protozoal agents were observed in and around the lesioned areas. By PCR analyzes using specific primers, 11 of the samples were positive for H. meleagridis only, whereas 5 were positive for T. gallinarum only; 14 samples tested positive for both agents. Sequence analysis showed 100% identity between all samples resulting in positive PCR. In addition, Escherichia coli was produced in microbiological culture (27 of 30). When all the results were evaluated together, it was concluded that H. meleagridis and T. gallinarum and secondary E. coli may cause high mortality in partridges under lay stress.","PeriodicalId":19991,"journal":{"name":"Pesquisa Veterinaria Brasileira","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67519297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
