Boophilus Microplus Ticks

<p>En Colombia, la presencia de la garrapata Rhipicephalus (Boophilus) microplus ha sido registrada en altitudes que oscilan entre 0 y 2.600 metros sobre el nivel del mar (msnm). Actualmente, no existen reportes de distribución de esta especie en el Altiplano cundiboyacense, zona geográfica de importancia nacional en la producción de leche. Para el presente trabajo se buscaron especímenes de cada uno de los estadios de la garrapata en bovinos y en potreros de 108 predios situados entre los 2.000 y 3.000 msnm, en las diferentes zonas del Altiplano cundiboyacense. Se colectaron 851 garrapatas, en total, de la especie R. (B.) microplus (100% de las muestras) en 34 predios ubicados entre los 1.966 y 2.903 msnm Este es el primer estudio en Colombia que registra la presencia de esta garrapata a una altitud superior a los 2.600 msnm y que caracteriza su distribución en el Altiplano cundiboyacense. Los resultados obtenidos demuestran la existencia de esta especie, ectoparásito de bovinos y vector de hemoparásitos, en zonas geográficas donde hasta hace algunos años no se registraba su presencia. Lo anterior plantea un panorama de riesgo para la presentación de babesiosis y anaplasmosis bovina en poblaciones altamente susceptibles. Estudios posteriores deberán definir la bioecología de esta garrapata en esta región y la prevalencia de infección en bovinos de los patógenos asociados.</p><p> </p><p><strong>Distribution of Rhipicephalus (Boophilus) microplus Ticks on Cattle and Farms from Altiplano Cundiboyacense (Colombia)</strong></p><p>In Colombia, the presence of Rhipicephalus (Boophilus) microplus ticks has been registered in altitudes ranging from zero to 2,600 meters above the sea level. Currently, there are no reports of its distribution in the Altiplano Cundiboyacense, an important dairy region of Colombia. In the present work, ticks of each stage were searched on cattle and pastures from 108 farms ranging from 2,000 to 3,000 meters of altitude. A total of 851 specimens of R. (B.) microplus (100% of total) were collected from 34 farms located between 1,966 and 2,903 meters of altitude. This is the first report in Colombia on the presence of this tick in altitudes higher than 2,600 meters and on its distribution in the Altiplano Cundiboyacense. These results confirm the existence of this tick as an ectoparasite of cattle, vector of haemoparasites, in areas where it was no previously reported, and they present a potential risk of transmission of these pathogens in highly susceptible bovine populations. Future research must define the bioecology and population dynamics of this tick in that region and the prevalence of cattle infected with tick-borne pathogens.</p>

Oropharyngeal and cloacal swabs from 117 captive psittacine birds presented at veterinary clinics (88) and from shelters/rescue centers of wildlife (29) were collected to determine the prevalence ofC. psittaciin captive birds in Costa Rica. Samples were collected during 2009 from a total of 19 different species of parrots, withAra macao(33),Amazona autumnalis(24),Amazona ochrocephala(21), andAra ararauna(8) being the most representative species sampled.C. psittaciwas detected in four (3.4%) birds using molecular detection (PCR). The positive samples belonged to birds presented at veterinary clinics; three of them wereAra macaoand oneAmazona ochrocephala. Three birds were adults; all positive birds showed no symptoms of illness and lived in homes with other birds, two in San José and two in Heredia. Sequencing was used to confirm the PCR positive results, showing that two samples ofC. psittacibelonged to genotype A, representing the first report of the presence of this genotype in Costa Rica. The detection of this bacterium in captive psittacine birds shows that there is a potential risk for people living or having contact with them and that there is a possibility of infecting other birds.

Hemolysin Bl

Bacillus cereus can cause diarrhea and emetic syndromes after ingestion of food contaminated with it. This ability is due to the production of enterotoxins by this microorganism, these being the hemolysin BL complex, which is involved in the diarrheal syndrome, and cereulide, which is responsible for the emetic syndrome. The detection of genes associated with the production of these toxins can predict the virulence of strains isolated from contaminated food. In this paper, we analyzed 100 samples of vegetables, 25 of each kind (broccoli, coriander, carrot, and lettuce) obtained from different markets in Mexico City and its metropolitan area. B. cereus was isolated in 32, 44, 84, and 68% of the samples of broccoli, carrot, lettuce, and coriander, respectively. The hblA gene (encoding one of the three subunits of hemolysin BL) was amplified in 100% of the B. cereus isolates, and the ces gene (encoding the cereulide) could not be amplified from any of them. This is the first report of B. cereus isolation from the vegetables analyzed in this work and, also, the first report in Mexico of the isolation from vegetables of strains with potential virulence. The results should serve as evidence of the potential risk of consuming these foods without proper treatment.

Abstract Background Hepatitis E virus (HEV) is a zoonotic pathogen and wild boars are recognised as reservoirs. HEV is the most common cause of acute viral hepatitis worldwide and it is usually transmitted by faecal-oral route. EU reported more than 21.000 human cases over the last 10 years (1). At the present, HEV comprises 8 genotypes and several subtypes. HEV genotypes 3 and 4 (HEV-3 and HEV-4) are zoonotic. This is the first report of HEV-3 subtype e and f in the wild boar population in Abruzzo region. Methods During the hunting season 2018-2019, liver samples from wild boars were analysed using Real Time RT-PCR for the detection of HEV RNA. Among these, positive sample were subjected to Whole Genome Sequencing for genotyping. After the quality check, reads were mapped using the nearest identified ref. sequence (KU176129) and the resulting HEV RNA sequences have been analysed using HEV net (open source software). Results Overall, 40 samples were tested positive for the detection of HEV RNA. Among these, 19 samples, with a Ct value ≤ 38, were selected for phylogenetic analysis. All RNA viral samples belonged to HEV-3. In particular, 2 RNA viral samples belonged to subtype e and 1 to subtype f. The others, instead, belonged to HEV-3 subtype c. Conclusions Up to now, only HEV-3 subtype c has been reported among wild boars in Abruzzo, an Italian region officially recognized as an HEV hot spot because of the high number of human cases and for the strong sero-prevalence among blood donors. In this study, we report for the first time the presence of HEV-3 subtypes e and f in the wild boar population of this area. Since HEV-3 subtypes e and f are commonly associated to human disease from consumption of raw/undercooked pork meats, these findings suggest the potential risk also associated with the consumption of wild boar meat. Nevertheless, this speculation needs further investigations. 1.EFSA (2017). Public health risks associated with HEV as a food-borne pathogen. E. Jou., 15(7) Key messages First report of the presence of HEV-3 subtypes e and f among wild boar population in Abruzzo region.

Risk Patients

Venous aneurysms are uncommon but they can have devastating consequences, including pulmonary embolism, other thromboembolic events and death. We report six cases of venous aneurysm of the extremities, in which the first sign of presence was acute pulmonary embolism. Surgical resection is recommended whenever possible. Our experience suggests that prophylactic surgery is cautiously recommended for low-risk patients with venous aneurysms of the abdomen and strongly recommended for extremity deep and superficial venous aneurysms for their potential risk of developing thromboembolic complications despite adequate anticoagulation. Other venous aneurysms should be excised only if they are symptomatic or enlarging.

Analyse Morphométrique

Les effets morphologiques et fonctionnels de la revascularisation transmyocardique au laser (RTML) sont analysés en conditions aiguës sur un modèle porcin. La paroi latérale du ventricule gauche de 15 porcs (poids moyen: 73 +/- 4kg) a été percée de 10 canaux laser (laser: Ho-YAG; longueur d'onde: 2.1 u, diamètre de la sonde: 1.75 mm). Une échocardiographie a été effectuée avant, ainsi que 5 min et 30 min après la procédure. Les paramètres échocardiographiques ont été enregistrés en court axe à la hauteur des canaux laser. Ils comprenaient la fraction d'éjection, la fraction de raccourcissement et la motilité segmentaire de la région lasérisée (échelle de 0 à 3: 0 = normal, 1 = hypokinésie, 2 = akinésie, 3 = dyskinésie). Après sacrifice de l'animal, la région lasérisée a été coupée dans un plan perpendiculaire aux canaux pour histologie et analyse morphométrique. Après 5 min, tous les index échocardiographiques ont montré une aggravation significative par rapport aux valeurs de base (p < 0.01). Après 30 min, plus aucun des paramètres ne présentait de variation significative par rapport aux valeurs de base. La surface de section des lésions mesurait 8.8 +/- 2.4 mm2 soit plus du triple de celle de la sonde laser elle-même (p < 0.01). En conditions aiguës, les lésions dues à la sonde de RTML sont nettement plus grande que la sonde elle-même et entraînent une baisse transitoire de la contractilité segmentaire sur un coeur sain. Ces résultats suggèrent que la RTML doit être utilisée avec prudence en clinique chez les patients avec une mauvaise fonction ventriculaire.
