Dogs are highly susceptible to the leptospiral infection, notably stray and sheltered dogs. Unsanitary conditions often observed in dog shelters may predispose introduction spread of leptospires among populations, potentially increasing chances for inadvertent adoption asymptomatically infected animals. The present work describes a longitudinal study using multidisciplinary approach identification chronically dogs characterization pathogenic strains circulating populations São Paulo, Brazil....
Wild species are susceptible to several typical domestic animal pathogens, and the increasingly close contact between these groups is a predictive factor for disease exposure. Some viruses important old‐known, others emerging or reemerging carnivorans have been identified as threats conservation of wild mammals. The purpose study was investigate occurrence bocaparvoviruses (BoVs, Parvoviridae family, Parvovirinae subfamily, Bocaparvovirus genus), parvoviruses ( Protoparvovirus genus,...
Abstract Wild mammals are susceptible to several viruses that can be transmitted humans. However, wildlife also impacted by spillover of from humans or domestic animals. Many xenarthrans vulnerable extinction, underscoring the importance monitoring potentially life-threatening for conservation efforts. This study investigated molecular presence coronaviruses, paramyxoviruses, and poxviruses in free-ranging anteaters armadillos Cerrado Pantanal biomes Mato Grosso do Sul, Brazil. Among 236...
During the global Mpox outbreak, potential role of dogs and cats in epidemiological chain monkeypox virus was suspected. Additionally, Brazil is endemic for vaccinia recently described Brazilian porcupinepox virus, both which require further investigation regarding their reservoirs. Given that are among most popular pets worldwide poxvirus infections could impact multispecies households, this study aimed to assess circulation poxviruses during pandemic. A pan-pox polymerase reaction assay...
Bats have been implicated as the main reservoir of coronavirus (CoV). Thus role these hosts on evolution and spread CoVs currently deserve attention emerging diseases surveillance programs. On view interest importance in bats occurrence molecular characterization CoV were conducted from Brazil. Three hundred five enteric contents 29 bat species tested using a panCoV nested RT-PCR. Nine specimens positive eight was suitable for RdRp gene sequencing. phylogeny showed that all strains this...
A modified TaqMan real-time polymerase chain reaction targeting a 138bp fragment within the lipl32 gene was developed to identify exclusively pathogenic Leptospira spp. in dog urine samples. Thirty-five samples from dogs with suspected clinical leptospirosis and 116 apparently healthy were tested for presence of leptospiral DNA using TaqMan-based assay. The results compared those well-established conventional PCR 16S RNA encoding associated nucleotide sequencing analysis. overall agreement...
This study determined the group A rotavirus occurrence in pig farms from 7 different cities São Paulo State, Brazil. Out of 143 samples, 70 tested positive. Sequence analyses 37 strains indicated that had G3, G5, G9, and P[6], P[13]/P[22]-like, P[23] genotypes.
The aim of the study was to evaluate central nervous system (CNS) lesions in non-effusive and effusive cases feline infectious peritonitis (FIP) regarding aspects related astrocytic microglial reactions.
Felid herpesvirus 1 is an important respiratory pathogen of domestic cats. This report presents the first case severe nonsuppurative meningoencephalitis caused by this virus in a cat.
This paper expands on a previous report about coronaviruses in quail. After surveillance carried out 2009 and 2010, some farmers started vaccinating quail with the Massachusetts avian infectious bronchitis virus serotype. The samples for this study were collected 2013 from São Paulo state southeastern Brazil. Pools of trachea, lungs, reproductive tract, kidneys, enteric contents laying hens kept same farms quail-only as well both healthy birds those showing bronchitis–like symptoms sampled...
Feline infectious peritonitis virus (FIPV) is highly virulent and responsible for the fatal disease feline (FIP), whereas enteric coronavirus (FECV) widespread among population typically causes asymptomatic infections. Some candidates genetic markers capable of differentiating these two pathotypes a unique (feline coronavirus) have been proposed by several studies. In present survey, in order to search that can differentiate FECV FIPV, clones 3a–c, E, M genes were sequenced from samples...
To evaluate the most controversial issue concerning current feline coronavirus (FCoV) virology, coexisting hypotheses of intrahost and interhost origins infectious peritonitis virus (FIPV) in regard to pathogenesis (FIP), this study aimed assess molecular diversity membrane gene FCoVs 190 samples from 10 cats with signs FIP 5 faecal without FIP. All non‐FIP 25.26% were positive for FCoV (M) gene. Mutations consisted SNP changes randomly scattered among sequences; few mutations resulted amino...
This study investigated the occurrence of rotavirus in porcine and Rattus norvegicus, at same time, on a pig farm city Jaguariúna, São Paulo, Brazil. Swine (n = 21) rat 6) fecal samples were analyzed by nested RT-PCR assay. Rotavirus occurred seven two samples. A total three one further submitted to genetic sequencing. The partial NSP5 gene phylogeny showed that all strains segregated genotype H1. These results point toward cross-species transmission between rats pigs surveyed represent...
We obtained the complete sequence of a novel poxvirus, tentatively named Brazilian porcupinepox virus, from wild porcupine (Coendou prehensilis) in Brazil that had skin and internal lesions characteristic poxvirus infection. The impact this lethal on survival species its potential zoonotic importance remain to be investigated.
Introduction: Staphylococci are the most important agents associated with bovine mastitis. This study aimed at characterizing resistance factors to antimicrobials in Staphylococcus spp. isolated from milk of cows subclinical mastitis.
 Methodology: In vitro 243 isolates commonly used clinical practice was evaluated. The detection and expression genes encoding mecA (gene penicillin binding protein 2a) mecALGA251 (mecA homologue), blaZ resistance), femA femB (genes essential - A B for...
Tritrichomonas foetus is an emergent and important enteric pathogen of cats, which causes prolonged diarrhoea in cats. This study describes a T. infection seven-month-old, entire male domestic shorthair kitten with six-month history persistent large intestinal diarrhoea, faecal incontinence, prostration, apathy weight loss. Parasites were microscopically observed confirmed by PCR DNA sequencing. Molecular analyses carried out comparing the sequence obtained this suis. Retrieved from GenBank....
ABSTRACT Avian coronavirus is the causative agent of infectious bronchitis in chickens, leading to multisystemic disease that might be controlled if adequate vaccine strains are used. This paper reports first complete genome sequence a Brazil type this virus (27,615 nucleotides [nt]) isolated from kidneys chicken.
Abstract Phage display (PD) is a tool for developing new molecules to control pathogens. Peptides selected by PD are commonly synthesised and tested, but the use of phage M13 displaying peptides as direct biding in intestinal tract has not yet been tested. This study evaluated whether can remain viable chicken gastrointestinal it causes injury or humoral immune response. We inoculated E. coli ER2738 (ECR) infected with into birds at different ages. found virus faeces 5 13 days after...
The total impact of the worldwide COVID-19 pandemic is still emerging, changing all relationships as a result, including those with pet animals. In infection process, use angiotensin-converting enzyme 2 (ACE2) cellular receptor to spike protein new coronavirus fundamental step. this sense, understanding which residue plays what role in interaction between SARS-CoV-2 glycoprotein and ACE2 from cats, dogs, ferrets an important guide for helping choose animal model can be used study pathology...
ABSTRACT Bovine clinical mastitis caused by Staphylococcus spp. is a serious and widespread disease in the world of dairy farming. Antimicrobial therapy fundamental importance prevention treatment infectious mastitis, but indiscriminate use antimicrobials acts as determining factor for spread disease. The present study evaluated resistance profiles 57 isolated from bovine to beta-lactams gentamicin, relating characteristics phenotype (in vitro susceptibility tests) genotype (detection...
