Leptospirosis is a neglected zoonosis with worldwide distribution. The causative agents are spirochete bacteria of the Leptospira genus, displaying huge diversity serovars, identity which critical for effective diagnosis and vaccination purposes. Among many other mammalian species, infects cattle, eliciting acute signs in calves, chronic disease adult animals often leading to abortions. In South America, including Uruguay, beef dairy export sources national income. Despite importance bovine...
Abstract Listeriosis is one of the most common nervous diseases in ruminants, and caused almost exclusively by Gram‐positive bacterium, Listeria monocytogenes . However, there are few reports listeriosis associated with L. innocua , which genetically closely related to but considered non‐pathogenic. In this work, we report two cases suppurative meningoencephalitis apparently previously healthy ruminants from different farms, strains were recovered. The whole genomes both isolates sequenced,...
Acute leptospirosis is an infrequent disease in sheep that can cause jaundice, haemolysis, haemoglobinuria, hepatitis and nephritis. In most reports the diagnoses have been made by clinical, pathological or serological evidence without isolation direct identification of agent. Here, we report one confirmed presumptive outbreak acute suckling lambs from two unrelated farms Uruguay with mortalities 9/60 (15%) 9/163 (5.5%) lambs. Both outbreaks occurred Sep-Oct 2017 after heavy rainfall...
Detection of bovine Babesia spp. and Anaplasma marginale is based on the reading Giemsa-stained blood or organ smears, which can have low sensitivity. Our aim was to improve detection A. by validating a multiplex PCR (mPCR). We used 466 samples and/or organs animals with signs presumptive autopsy findings babesiosis anaplasmosis. The primers in our mPCR amplified rap-1a gene region bovis B. bigemina, msp-5 marginale. Bayesian model non-informative priori distribution for prevalence estimate...
ABSTRACT: The aim of the study was to detect Listeria spp., particularly monocytogenes, in cattle and environment pasture based dairy farms Paysandú, Uruguay. A two-stage sampling conducted, 10 were selected by probability proportional size. single visit made each farm. Samples from bovine faeces, feedstuffs, bulk tank milk, drinking water soil entry exit pens milking parlour collected for bacteriological studies. PCR assays used confirm species determine serotype profile L. monocytogenes...
Two outbreaks of progressive hind limb paresis in cats (Felis catus) caused by parasitic meningomyelitis Uruguay are reported. The case studies occurred 2008 and 2009 respectively, the rural areas Fray Bentos (33° 07' 40.39'' S) were characterized hindquarter paralysis. This paralysis was had a chronic progression approximately 12 months until death or euthanasia animals. Clinical symptoms started with ataxia hindquarters lateral side-to-side swaying culminated total animals sent for...
ABSTRACT: Listeriosis is an infectious disease caused by bacteria of the genus Listeria, neurological form being more common in ruminants. There are many reports listeriosis small ruminants region that includes Brazil, Argentina and Uruguay. However, these diagnoses were mainly based on histological lesions central nervous system (CNS) without isolation characterization involved Listeria strains. The aim this study was to report sheep goats cases from 2016 2021 northwestern diagnosis made...
Intrauterine infusions have been widely used for the treatment of endometritis in mare. Nevertheless, their consequences on endocrine and endometrial molecular aspects are unknown. We studied effect a 1% povidone-iodine solution intrauterine infusion progesterone levels, histology estrogen (ERα) (PR) receptor distribution by immunohistochemistry.Fourteen healthy mares were this study. Estruses synchronized seven treated with at days 0 2 post ovulation two consecutive estrous cycles. Uterine...
ABSTRACT: We aimed to genotype the South American clinical isolates of Pythium insidiosum using single nucleotide polymorphisms (SNP) ribosomal DNA sequences (rDNA). Previously, an SNP-based multiplex-PCR was able distinguish three different clades P. isolates. Thus, we used this assay evaluate (n=32), standard strains from Costa Rica (n=4), Thailand (n=3), Japan (n=1), and India a strain aphanidermatum, Brazilian environmental torulosum, rhizo-oryzae pachycaule voucher (n=3). It possible...
Abstract An outbreak of Closantel intoxication in sheep Uruguay is described. The occurred a group 1300 weaning lambs treated orally with 10% solution Closantel. One hundred forty eight showed clinical signs and 14 died. included mydriasis, nystagmus, negative pupillary reflex, bilateral blindness, bump into objects, lateral movement the head. No macroscopic lesions were observed. histological retina cytoplasmic vacuolization ganglion cells inner outer nuclear layers different degrees...
A pastured 2-y-old cross-breed bull developed brainstem encephalitis (rhombencephalitis); Listeria monocytogenes was isolated from the brain. In brainstem, there perivascular cuffing, multiple microabscesses, and positive immunostaining for L. monocytogenes. Samples of bovine feces, water, feedstuffs, milking parlor soil, bulk tank milk were collected dairy farm. Seven isolates genus obtained, 6 innocua 1 monocytogenes, which found in pasture where grazed. Both belonged to serotype 4b...
espanolLa rangeliosis canina es una enfermedad causada por el protozoario Rangelia vitalii y transmitida garrapatas. Afecta caninos domesticos silvestres, provocando un cuadro de anemia hemolitica trombocitopenia. En Uruguay ha sido reportada en los Departamentos Artigas, Salto Treinta Tres. El presente trabajo describe foco litoral oeste del Uruguay, diagnosticado mediante estudios epidemiologicos, clinicos, hematologicos, anatomopatologicos tecnicas moleculares (PCR/secuenciacion). estudio...
Foi realizado um estudo retrospectivo de 14 focos febre catarral maligna (FCM) em bovinos, detectados nos anos 1999-2011, a partir dos arquivos da Seção Anatomia Patológica Divisão Laboratórios Veterinários (DILAVE) "Miguel C. Rubino" Montevideo. Foram analisados os dados epidemiológicos, apresentação clínica e lesões macroscópicas histopatológicas. Para detecção do herpesvírus ovino tipo 2 (OvHV-2) foi utilizada técnica PCR sobre as amostras sistema nervoso central bovinos 12 focos. Os...
The major surface protein 1a (MSP1a) gene has been used to characterize Anaplasma marginale genetic diversity. This pathogen causes significant productivity and economic losses the cattle industry. objective of present study was report first characterization A. diversity in Uruguay based on MSP1a genotypes their putative relationship with Rhipicephalus microplus . cross-sectional conducted between 2016 2020. included whole blood samples from clinical cases bovine anaplasmosis obtained 30...
<title>Abstract</title> In Uruguay and other countries of southern South America, listeriosis in cattle has been described, often relying solely on histological lesions for diagnosis. This study aimed to: i) analyze a case-series bovine diagnosed through combined pathological bacteriological methods and, ii) characterize the isolated <italic>Listeria</italic> strains. From 2014 to 2022, twelve cases were diagnosed. Eleven presented as neurolisteriosis, while one involved third-trimester...
Pythiosis is a disease widely distributed worldwide caused by Pythium insidiosum. It transmitted and propagated in semi-aquatic environments, mainly affecting equines, canines, felines, cattle humans. In Paysandu County, Uruguay, the month of May 2017, case pitiosis was registered 24-year-old Creole breed female equine. An extensive circular lesion located ventral abdominal area surgically removed. Macroscopically, it observed granulation tissue, multifocal areas necrosis with suppurative...
