Study of lobation and vascularization of the lungs of wild boar (Sus scrofa)

The purpose of this study was to describe the anatomy of the lungs of wild boars for comparison with those of domestic swine. It was found that the right lung of the wild boar is divided into four lobes: cranial, median, caudal and accessory, whereas the left lung is divided into two lobes: cranial and caudal. In 93.4% of the cases, right pulmonary artery separates into the ascendant, descendant, median, accessory and caudal branches. In 73.3% of the cases, left pulmonary artery separates most frequently to form three branches to the cranial lobe, whereas the median lobe is generally supplied by only one arterial branch. There is a single pattern of bronchial distribution: in the right lung a tracheal bronchus leads to the cranial lobe, where it separates into the cranial and caudal bronchi and there are also bronchi to the median, caudal and accessory lobes. In the left lung, the large bronchus separates to form two branches, one of which further separates to form two branches to the cranial lobe whereas the other forms a single branch to the caudal lobe.

Purification and partial characterization of cathepsin D from porcine (Sus scrofa) liver using affinity chromatography

Cathepsin D, a lysosomal aspartic protease, has been purified from porcine liver using a combination of pepstatin-A agarose and Affi-Gel Blue affinity chromatography, followed by size-exclusion chromatography. The purified protein consists of two polypeptide chains of 15 and 30 kDa, and has an isoelectric point of 6.8. Porcine liver cathepsin D has maximum activity at pH 2.5-3.0 as determined by its activity against hemoglobin, with a K-cat of 14.3 s(-1) and a k(cat)/K-M of 2.70 x 10(6) s(-1) M-1 as determined by the hydrolysis of a fluorogenic peptide substrate.

Carcass and meat quality traits of wild boar (Sus scrofa s. L.) with 2n=36 karyotype compared to those of phenotypically similar crossbreeds (2n=37 and 2n=38) raised under same farming conditions. 1. Carcass quantity and meat dressing

The aim of this study was to compare wild boar (chromosomal number 2n = 36) to phenotypically similar animals of 2n = 37 and 2n = 38 chromosomes (crossbreeds) with respect to live weight, carcass yield, meat yield, fat and weight of inner organs. All animals were born and raised on the same farm and slaughtered at 39 weeks. The final live weight of wild boar 2n = 36 was significantly lower (47.2 kg) as compared to crossbreeds (80.0 kg). Animals 2n = 36 had more carcass yields (65.5%) than 2n = 37 karyotype (64.9%) and 2n = 38 (64.4%). Wild boar had the highest yields for the cuts with bones and boneless cuts compared to crossbreeds. Therefore, variations in karyotype are accompanied by differences in some carcass quantitative traits, i.e., 2n = 36 grow and fatten slower than crossbreeds 2n = 37 and 2n = 38.

Occurrence record of Sus scrofa Linnaeus, 1758 (Mammalia: Artiodactyla) at Estação Ecológica de Itirapina, São Paulo state, Brazil

Invasive species are the second cause of biodiversity decline in the world. Among the many invasive species, the Sus scrofa (wild boar) is amongst those that cause more impacts. Our aim was to report the presence of the wild boar in the last remaining open area of Cerrado in the São Paulo state, Brazil. In September 2007 an individual was seen and tracks were also observed during the same period at the Estação Ecológica de Itirapina. © 2013 Check List and Authors.

Bronchopneumonia in wild boar (Sus scrofa) caused by Rhodococcus equi carrying the VapB type 8 plasmid

Background: Rhodococcus equi is associated with pyogranulomatous infections, especially in foals, and this bacterium has also emerged as a pathogen for humans, particularly immunocompromised patients. R. equi infections in pigs, wild boar (Sus scrofa) and humans are mainly due to strains carrying the intermediate virulence (VapB) plasmid. In Brazil, R. equi carrying the VapB type 8 plasmid is the most common type recovered from humans co-infected with the human immunodeficiency virus (HIV). R. equi infection in pigs and wild boar is restricted predominantly to the lymphatic system, without any reports of pulmonary manifestations. Findings. This report describes the microbiological and histopathological findings, and molecular characterization of R. equi in two bronchopneumonia cases in wild boar using PCR and plasmid profile analysis by digestion with restriction endonucleases. The histological findings were suggestive of pyogranulomatous infection, and the plasmid profile of both R. equi isolates enabled the characterization of the strains as VapB type 8. Conclusions: This is the first report of bronchopneumonia in wild boar due to R. equi. The detection of the VapB type 8 plasmid in R. equi isolates emphasize that wild boar may be a potential source of pathogenic R. equi strains for humans. © 2013 de Vargas et al.; licensee BioMed Central Ltd.

Avaliação imunofenotípica de subpopulações linfocitárias no sangue do cordão umbilical e periférico de suínos neonatos (Sus scrofa)

Considering the importance of umbilical cord blood as a potential source of stem cell and, on the other hand, the use of the domestic swine (Sus scrofa) as a useful model for biomedical research in regenerative medicine and aiming to contribute about the quantification of lymphocyte subsets in umbilical cord blood and peripheral blood of newborn piglets, this study aimed to quantify CD4+, CD5+ and CD8+ cells from umbilical cord blood and peripheral blood from pigs at term blood samples. Were analyzed samples of the umbilical cord blood and peripheral of 48 piglets of Topigs lineage, from healthy mothers, artificially inseminated and natural birth. Blood samples were collected from the umbilical cord at birth, by the umbilical vein, and peripheral blood by venous sinus retro-ophthalmic. The immunological measurements of CD4+, CD5+ and CD8+ were obtained by flow cytometry. The relative average values for the CD4+, CD5+ e CD8+ counts in umbilical cord blood and peripheral blood of newborn piglets were inferior to those reported for peripheral blood in adult pigs, suggesting immunological immaturity. The ratio CD4+:CD8+ in umbilical cord blood (3.2±1.2%) and peripheral blood (3.2±1.7%) showed a predominance of TCD4+ over TCD8+. The percentage of CD4+ and CD8+ cells was 1.37±0.86% and 1.15±0.57%, respectively, in umbilical cord blood and peripheral blood.

Valores de referência de uréia e creatinina para javali (sus scrofa scrofa, linnaeus, 1758) em cativeiro

In Brazil, the commercial breeding of wild boars (Sus scrofa scrofa) is rapidly expanding. Given the significance of reference values for biochemical analysis for diagnosis of pathological processes and the limitation of data in the literature on this species, Blood samples were collected for determination of biochemical values in 160 wild boars from 180 to 300 days old, clinically healthy farms. The reference range for creatinine was similar to the normal range for swine (1,0 – 2,7mg/dL). There were differences between genders, only for the determination of urea, where the males were higher, although similar to pigs (10 – 30mg/dL). The females, with values from 13.03 to 44.78 mg / dL, do not have statistically significant.

Influence of carrion smell and rebaiting time on the efficiency of pitfall traps to dung beetle sampling

Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) are very useful insects, as they improve the chemo-physical properties of soil, clean pastures from dung pads, and help control symbovine flies associated with bovine cattle. Their importance makes it fundamental to sample and survey them adequately. The objectives of the present study were to determine the influence of decaying insects trapped in pitfalls on the attractiveness of Moura pig Sus scrofa L. (Suidae) and collared peccary Tayassu tajacu (L.) (Tayassuidae) dung used as baits to lure dung beetles, and to establish how long these baits remain attractive to dung beetles when used in these traps. Some dung beetle species seemed to be able to discriminate against foul smell from decaying insects within the first 24 h, hence decreasing trap efficiency. This was more evident in peccary dung-baited traps, which proved to be the least attractive bait. Attractiveness lasted only 24 h for peccary dung, after which it became unattractive, whereas the pig dung bait was highly attractive for 48 h, after which its attractiveness diminished but was not completely lost.
