Klebsiella species frequently cause clinically relevant human infections worldwide. We report the draft genome sequence of a Brazilian clinical isolate (Bz19) of the recently recognized species Klebsiella variicola. The comparison of Bz19 genome content with the At-22 (environmental K. variicola) and several clinical Klebsiella pneumoniae shows that these species share a set of virulence-associated determinants. Of note, this K. variicola strain harbours a plasmid-like element that shares the same backbone present in a multidrug-resistant plasmid found in a clinical K. pneumoniae isolated in USA.
BACKGROUND Mycolicibacterium fortuitum is an opportunistic pathogen associated with human and animal infection worldwide. Studies concerning this species are mainly represented by case reports, some of them addressing drug susceptibility with a focus on a specific geographic region, so there is a gap in relation to the global epidemiological scenario.OBJECTIVES We aimed determine the global epidemiological scenario of M. fortuitum and analyse its traits associated with pathogenicity.METHODS Based on publicly available genomes of M. fortuitum and a genome from Brazil (this study), we performed a genomic epidemiology analysis and in silico and in vitro characterisation of the resistome and virulome of this species.FINDINGS Three main clusters were defined, one including isolates from the environment, human and animal infections recovered over nearly a century. An apparent intrinsic resistome comprises mechanisms associated with macrolides, betalactams, aminoglycosides and antitubercular drugs such as rifampin. Besides, the virulome presented Type VII secretion systems (T7SS), including ESX-1, ESX-3, ESX-4 and ESX-4-bis, some of which play a role on the virulence of Mycobacteriaceae species.MAIN CONCLUSIONS Here, M. fortuitum was revealed as a reservoir of an expressive intrinsic resistome, as well as a virulome that may contribute to its success as a global opportunist pathogen.
Endoparasitic infections are associated with morbidity in cats. This study aimed to investigate the occurrence of endoparasites among cats of different life stages in the city of Rio de Janeiro, Brazil. The samples were analyzed individually by macroscopic exploration for proglottids and centrifugal-flotation. Stool samples were obtained from household cats (n = 57) and shelter cats (n = 336). Endoparasites were detected in 50.64% of the samples. Among household and shelter cats, 21.05% and 55.66% were infected with endoparasites, respectively. In household cats, the most prevalent endoparasites were Ancylostoma spp. (in 25.0%) and Strongyloides spp. (in 25.0%), followed by Toxocara spp. (in 16.67%), Dipylidium caninum (in 16.67%), Cystoisospora spp. (in 8.33%), and Uncinaria spp. + Ancylostoma spp. (in 8.33%). In shelter cats, the most prevalent endoparasite was Ancylostoma spp. (in 29.41%), followed by Cystoisospora spp. (in 26.20%) and Toxocara spp. (in 16.58%), as well as Cystoisospora spp. + Toxocara spp. (in 8.02%); Ancylostoma spp. + Toxocara spp. (in 11.76%); Cystoisospora spp. + Ancylostoma spp. (in 3.74%); Cystoisospora spp. + Toxocara spp. + Ancylostoma spp. (in 3.21%); and Dipylidium caninum + Ancylostoma spp. (in 0.53%). Endoparasitic infections in cats underscore the need for preventive veterinary care and routine coproparasitologic tests.
Mycolicibacterium fortuitum is a fast-growing bacterium and an opportunistic pathogen implicated in human and animal infections. Here we report the first case and genetic characterization of a strain of M. fortuitum isolated from skin lesions of a companion cat with atypical cutaneous mycobacteriosis in Brazil. In addition, the genome of this strain was sequenced, representing the first genome of this opportunistic pathogen isolated from an animal infection. The in silico and in vitro analysis regarding antibiotic resistance of this strain showed an intrinsic multiresistance antibiotic profile. However, this strain showed sensitivity to amikacin and ciprofloxacin, and the cat was treated long-term with these drugs.
RESUMOAs anomalias anorretais são defeitos congênitos de ocorrência rara em diversas espécies; dentre estas, a atresia anal é a mais frequentemente observada na espécie canina e geralmente está associada à fístula reto-vaginal. Nesse trabalho, é descrito o caso de uma cadela, sem raça definida, com 4 meses de idade, atendida no Hospital Universitário de Medicina Veterinária da Universidade Federal Fluminense (HUVET-UFF) com sintomatologia e histórico de eliminação de fezes e urina através de um único orifício, além de prostração, tenesmo e distensão abdominal. Durante os procedimentos diagnóstico e cirúrgico, verificou-se a comunicação entre o reto e a vagina, caracterizando a fístula reto-vaginal secundária à atresia anal. O procedimento cirúrgico é a única possibilidade de sobrevida para pacientes acometidos por esta enfermidade e deve ser realizado o mais precocemente possível. Portanto, esse trabalho objetivou relatar o resultado satisfatório da correção cirúrgica tardia da anomalia em uma cadela de quatro meses, resultando em recuperação da paciente e garantia da qualidade de vida. PALAVRAS-CHAVE: Anoplastia; Cão; Vagina.
