São Paulo (SP), a densely inhabited state in southeast Brazil that contains the fourth most populated city in the world, recently experienced its largest yellow fever virus (YFV) outbreak in decades. YFV does not normally circulate extensively in SP, so most people were unvaccinated when the outbreak began. Surveillance in non-human primates (NHPs) is important for determining the magnitude and geographic extent of an epizootic, thereby helping to evaluate the risk of YFV spillover to humans. Data from infected NHPs can give more accurate insights into YFV spread than when using data from human cases alone. To contextualise human cases, identify epizootic foci and uncover the rate and direction of YFV spread in SP, we generated and analysed virus genomic data and epizootic case data from NHP in SP. We report the occurrence of three spatiotemporally distinct phases of the outbreak in SP prior to February 2018. We generated 51 new virus genomes from YFV positive cases identified in 23 different municipalities in SP, mostly sampled from non-human primates between October 2016 and January 2018. Although we observe substantial heterogeneity in lineage dispersal velocities between phylogenetic branches, continuous phylogeographic analyses of generated YFV genomes suggest that YFV lineages spread in SP state at a mean rate of approximately 1km per day during all phases of the outbreak. Viral lineages from the first epizootic phase in northern SP subsequently dispersed towards the south of the state to cause the second and third epizootic phases there. This alters our understanding of how YFV was introduced into the densely populated south of SP state. Our results shed light on the sylvatic transmission of yellow fever in highly fragmented forested regions in SP state and highlight the importance of continued surveillance of zoonotic pathogens in sentinel species.

A major outbreak of yellow fever (YF) occurred in Brazil during 2016-2018. Epizootics in New World nonhuman primates are sentinel events for YF virus circulation. However, genus-specific susceptibilities and suitability for YF surveillance remain poorly understood. We obtained and compared epidemiologic, histopathologic, immunohistochemical, and molecular results from 93 human and 1,752 primate cases submitted during the recent YF outbreak in Brazil (2017), with the support of the Brazilian National YF Surveillance Program. We detected heterogeneous YF-associated profiles among the various genera of primates we analyzed. Alouatta primates were the most reliable sentinel; Sapajus and Callicebus primates had higher viral loads but lower proportional mortality rates. Callithrix primates were the least sensitive, showing lower viral loads, lower proportional mortality rates, and no demonstrable YF virus antigen or extensive lesions in liver, despite detectable viral RNA. These differences in susceptibility, viral load, and mortality rates should be considered in strategic surveillance of epizootics and control measures for YF.

Perineal hernia results from weakening and/or the inability of the pelvic diaphragm to support the rectal wall, promoting caudal displacement of abdominal or pelvic organs in the perineum. Unneutered male dogs aged between 7 and 10 years are the most affected, being rare in females. The main clinical signs are unilateral or bilateral swelling of the perineal region, associated or not with tenesmus, dysuria, urinary and/or fecal incontinence, anuria and pain during defecation. The diagnosis is based on clinical history, anamnesis, physical examination, and complementary tests such as radiography and ultrasound. Clinical treatment can be done in some cases, but surgical intervention is required to resolve the problem. The present work aims to report the case of a patient treated at the FullPet Veterinary Clinic in Guarulhos, São Paulo, Brazil, a 7-year-old male Yorkshire canine, unneutered, weighing 4.5 kg. The same was submitted to surgery by the tradi­tional method of suture with nylon thread and enteropexy. When there was recurrence, surgical reintervention was necessary to correct the hernia using a polypropylene mesh.

The sunflower cake and palm cake are two by-products of the biodiesel industry with different profiles of fatty acids (FA). The sunflower cake has 60% of unsaturated FA and the palm cake is rich in medium-chain fatty acids. Feeding both sources to ruminants may increase FA digestibility and improve energy intake. Here, an abstract of an article by de Souza et al evaluating the interaction of the dietary supplementation of sunflower cake and palm cake on DMI and blood parameters of feedlot lambs is presented.

La hernia perineal resulta del debilitamiento y/o incapacidad del diafragma pélvico para sostener la pared rectal, lo que promueve el desplazamiento caudal de los órganos abdominales o pélvicos en el perineo. Los perros machos no castrados de entre 7 y 10 años son los más afectados, siendo raro en las hembras. Los principales signos clínicos son tumefacción unilateral o bilateral de la región perineal, asociada o no a tenesmo, disuria, incontinencia urinaria y/o fecal, anuria y dolor durante la defecación. El diagnóstico se basa en la historia clínica, la anamnesis, el examen físico y pruebas complementarias como la radiografía simple y la ecografía. El tratamiento clínico se puede hacer en algunos casos, pero se requiere una intervención quirúrgica para resolver el problema. El presente trabajo tiene como objetivo relatar el caso de un paciente atendido en la Clínica Veterinaria FullPet de Guarulhos, São Paulo, Brasil, un canino Yorkshire macho de 7 años, sin castrar, con un peso de 4,5 kg. Fue intervenido quirúrgicamente por el método tradicional de sutura con hilo de nylon y enteropexia. Cuando hubo recidiva, fue necesaria la reintervención quirúrgica para corregir la hernia mediante una malla de polipropileno.

ABSTRACT IN FRENCH: L'article analyse les flux et reflux de la «capoeira» entre le Brésil et le Portugal, et met en évidence les déplacements, la complexité et la dynamicité du processus. Le caractère conflictuel des rapports inter-ethniques construits au moyen de pratiques culturelles significatives renforce la formation de processus identitaires qui articulent le général avec les singularités locales, avec des sujets qui dirigent et cherchent à donner un sens à leurs propres vies, bien que soumis à des contraintes structurelles qui influent sur les productions culturelles spécifiques. // ABSTRACT IN ENGLISH: This article analyses exchanges between Brazil and Portugal, demonstrating the shifts, the complexities and the dynamic nature of this process. The conflictual nature of inter-ethnic relationships built up through significant cultural practices help to consolidate identity-forming processes linking the general with the locally specific, with individuals directing and seeking meaning in their own lives, even if they are subject to the structural constraints which influence specific cultural production.
