An outbreak of influenza A(H7N2) virus in cats in a shelter in New York, NY, USA, resulted in zoonotic transmission. Virus isolated from the infected human was closely related to virus isolated from a cat; both were related to low pathogenicity avian influenza A(H7N2) viruses detected in the United States during the early 2000s.

Characterization of Streptococcus pyogenes from Animal Clinical Specimens, Spain

Emerging Infectious Diseases December 2017 V.23 N.12 P.2011-2016


Streptococcus pyogenes appears to be almost exclusively restricted to humans, with few reports on isolation from animals.

We provide a detailed characterization (emm typing, pulsed-field gel electrophoresis [PFGE], and multilocus sequence typing [MLST]) of 15 S. pyogenes isolates from animals associated with different clinical backgrounds.

We also investigated erythromycin resistance mechanisms and phenotypes and virulence genes.

We observed 2 emm types: emm12 (11 isolates) and emm77 (4 isolates).

Similarly, we observed 2 genetic linages, sequence type (ST) 26 and ST63. Most isolates exhibited the M macrolide resistance phenotype and the mefA/ermB genotype.

Isolates were grouped into 2 clones on the basis of emm-MLST-PFGE-virulence gene profile combinations: clone 1, characterized by the combined genotype emm12-ST36-pulsotype A-speG; and clone 2, characterized by the genotype emm77-ST63-pulsotype B-speC.

Our results do not show conclusively that animals may represent a new reservoir of S. pyogenes but indicate the ability of human-derived S. pyogenes isolates to colonize and infect animals.

LEPTOSPIROSIS – Puesta al día

Revista Chilena de Infectología Junio 2007 V.24 N.3 P.220-226

Zunino, P. Pizarro

We review epidemiological, clinical, laboratory and therapeutic aspects of leptospirosis. In relation to the epidemiology it is worth noting the importance of recreational and occupational risk factors, as well as the lack of date available in Chile before the year 2000, when leptospirosis became the object of epidemiological surveillance. There are many forms of clinical presentations for this disease and often signs and symptoms may be nonspecific. Thus, differential diagnosis must include many clinical entities. Laboratory diagnosis, on the other hand, is complex and not widely available. Although still controversial, a literature review supports antimicrobial treatment, with different antibiotics to choose from.

Leptospirosis is a worldwide zoonotic infection with a much greater incidence in tropical regions and has now been identified as one of the emerging infectious diseases. The epidemiology of leptospirosis has been modified by changes in animal husbandry, climate, and human behavior. Resurgent interest in leptospirosis has resulted from large outbreaks that have received significant publicity. The development of simpler, rapid assays for diagnosis has been based largely on the recognition that early initiation of antibiotic therapy is important in acute disease but also on the need for assays which can be used more widely. In this review, the complex taxonomy of leptospires, previously based on serology and recently modified by a genotypic classification, is discussed, and the clinical and epidemiological value of molecular diagnosis and typing is also evaluated.

Leptospirosis. Puesta al día

Revista Chilena de Infectologia Junio 2007 V.24 N.3 P.220-226

Se revisan los aspectos clínicos, diagnóstico de laboratorio y alternativas terapéuticas para la leptospirosis. Destaca en la epidemiología el riesgo ocupa-cional y laboral y la falta de datos, por no haber constituido en Chile tema de vigilancia epidemiológica hasta el año 2000.

Los datos clínicos evidencian una notable heterogeneidad de manifestaciones, muchas veces inespecíficas. La complejidad del diagnóstico diferencial que plantea hace necesario incluirlo en el análisis causal de múltiples situaciones clínicas.

El diagnóstico de laboratorio es aún complejo y poco accesible. Aunque es todavía controvertido, el análisis de la literatura apoya el beneficio del tratamiento antimicrobiano con varias alternativas de elección.
