Escherichia coli isolated from pyometra and cystitis in the same animal exhibit a wide phenotypic similarity.

Aims: Pyometra and cystitis caused by Escherichia coli are common diseases identified in canine or feline females. The origin of pyometra infection remains uncertain, and effective prevention strategies for this disease are still unknown. This study aimed to provide a phenotypic characterization, including antimicrobial resistance and virulence profiles, of endometrial pathogenic (EnPEC) and uropathogenic (UPEC) E.

A cross-sectional study on Campylobacter fetus subsp. venerealis prevalence and associated factors in Brazilian southern cattle farms.

Cattle farming is a major livestock activity with economic relevance in Rio Grande do Sul (RS), Brazil. However, this activity is still considered of intermediate to low technological level, and in this region, there are few epidemiologic reports of Campylobacter fetus subsp. venerealis (Cfv), the causative agent of bovine genital campylobacteriosis (BGC).

Characterization of the cervicovaginal microbiota of female beef cattle harboring Campylobacter fetus subsp. venerealis using 16S rDNA gene sequencing.

Bovine genital campylobacteriosis (BGC) is a leading cause of return to estrus in cows. The etiologic agent, Campylobacter fetus subsp. venerealis (Cfv) is transmitted by venereal route.

Genetic and molecular Omp25 analyses from worldwide Brucella canis strains: Possible mutational influences in protein function.

Brucella canis is responsible for canine brucellosis, a neglected zoonotic disease. The omp25 gene has been described as an important marker for Brucella intra-species differentiation, in addition to the ability to interact with the host immune system. Therefore, this study investigated the omp25 sequence from B.

Cows' reproductive performances and parity order influences the cervicovaginal fungal community.

Fungi have already been described as etiological agents of reproductive diseases such as endometritis and infertility in cows. However, few studies have been developed to elucidate the entire cervicovaginal fungal communities in cows. Therefore, our study aimed to characterize the fungal community present in the cervix of cows with different reproductive performances.

Pet Pyometra: Correlating Bacteria Pathogenicity to Endometrial Histological Changes.

Pyometra is a life-threatening infectious disease that frequently affects bitches and queens. Although histopathological patterns of pyometra have been extensively explored, the microbiological aspects, such as bacteria pathogenicity, have not been correlated to microscopy endometrial lesions so far. In this study, these two pathological aspects of pyometra were analysed and correlated.

Frozen bovine preputial mucus as a suitable sample for the direct molecular diagnosis of Campylobacter fetus subsp. venerealis.

Long transportation times remain a challenge to the satisfactory diagnosis of Campylobacter fetus subsp. venerealis (Cfv). Here we demonstrated that samples of frozen bovine preputial mucus maintained at -20 °C for 10 days can be used as an alternative source for molecular diagnosis of Cfv.

Omphalitis, urachocystitis and septicemia by Streptococcus dysgalactiae in a southern right whale calf Eubalaena australis, Brazil.

Southern right whales Eubalaena australis (SRW) use the southern coast of Brazil as a wintering and calving ground. Other than anthropogenic threats, there is limited knowledge on health and disease aspects for this species. We report the gross and microscopic findings and microbiological identification of streptococcal septicemia in a SRW calf.
