RESUMO
The coinfection of Avibacterium paragallinarum and Ornithobacterium rhinotracheale in two outbreaks of infectious coryza from Peru is reported. The diagnosis was confirmed by bacteriologic isolation, PCR testing, and sequencing of the 16S rRNA gene. The susceptibility of the isolates to 12 antimicrobial agents was tested by a disk diffusion method. The isolates were susceptible to amoxicillin/clavulanic acid and florfenicol and were resistant to oxacillin and sulfamethoxazole/trimethoprim. The coinfection of Av. paragallinarum and O. rhinotracheale and the severity of clinical signs were evaluated by experimental infection of specific-pathogen-free chickens. The group inoculated with O. rhinotracheale alone presented minimal clinical signs in 3 of 10 chickens. However, the groups inoculated with both Av. paragallinarum and O. rhinotracheale induced the most-severe clinical signs compared with the group inoculated with Av. paragallinarum alone. In conclusion, coinfections with Av. paragallinarum and O. rhinotracheale may occur, and these outbreaks could be more severe than single infections. Hence, the prevention, control, and diagnosis of Av. paragallinarum with O. rhinotracheale are important in outbreaks of infectious coryza.

In the course of an investigation to prepare the hypothetic new double perovskite La(3)Co(2)VO(9) with Co(2+) and V(5+) in octahedral sites, we obtained the new simple perovskite LaCo(0.71(1))V(0.29(1))O(2.97(3)) as the main phase. The pure compound was then synthesized by the citrate decomposition method. The crystal structure was studied by X-ray (PXRD) and powder neutron diffraction (PND). Physical properties were characterized by X-ray absorption spectroscopy (XAS), X-ray emission spectroscopy (XES) and thermogravimetric analysis (TGA). Rietveld refinements were performed in the orthorhombic space group Pnma (#62). Refined cell parameters were a = 5.4762(2) Å, b = 7.7609(2) Å and c = 5.5122(1) Å. Magnetization measurements showed that this perovskite is an antiferromagnet with a Neel temperature of 15 K. At high T the magnetization follows the Curie-Weiss law corrected by temperature independent paramagnetism (TIP) showing an effective magnetic moment of 3.03µ(B) well described by the contribution of Co(2+) (HS), Co(3+) (IS), V(3+) and V(4+) ions. The crystallographic formula was refined by PND and oxidation state distribution was determined by the combination of PND, XAS, TGA and magnetic measurements.
RESUMO
El dolor ha sido considerado un aspecto dentro de los sìntomas más comunes dentro de las laceraciones de la mucosa oral. El tratamiento aplicado en estos va dirigido fundamentalmente a la dismunución de esta sintomatología. Numerosos han sido los métodos para lograr este propósito, que van desde los ácidos que cauterizan la lesión, hasta sustancias protectoras y cicatrizantes. El trabajo tiene como objetivo mostrar los resultados clínicos de la aplicación de un cianocrilato de n-butilo (Tisuacryl)en la disminución de las molestias dolorosas en lesiones de la mucosa oral producidas por diferentes causas. El producto se ha evaluado en esta aplicación desde 1998 en 25 pacientes, sin restringir edad o sexo que acudieron a los servicios estomatológicos de la Empresa Aerogaviota y la clìnica estomatológica Docente de Bauta con lesiones o laceraciones de la mucosa oral de cualquier localización, dimensión y etiología. Los resultados demuestran que el tratamiento con Tisuacryl disminuye el dolor en los casos de lesiones de mucosa oral, permitiendo al paciente la ingestión inmediata de alimentos(AU)
