Sus Scrofa Domesticus

Antemortem domestic pig (Sus scrofa domesticus) dental pathology literature is sparse. This observational descriptive study evaluated 23 client-owned pigs that while sedated/anesthetized for routine annual care had intraoral dental radiographs and an oral examination performed. Age, gender, weight, and breed for each pig were recorded. Oral examination and radiographic findings were reviewed to create a comprehensive list of dental abnormalities identified. Descriptive statistics were performed to summarize the data. The study population included 14 castrated males and 20 Vietnamese pot-bellied mini-pigs. The median age was 3 years (range 2-12 years), and the median weight was 39 kg (range 11-140 kg). The most common finding was missing teeth (21/23 pigs); the first premolar tooth was the most likely to be absent (64/106 missing teeth). Periodontal disease was common (20/23 pigs). Advanced stages primarily affected the first molar teeth frequently in the form of a mucogingival defect. Supernumerary roots were discovered on the maxillary canine teeth in female pigs only (10/25 teeth with supernumerary roots). The most common persistent deciduous tooth was the maxillary second incisor (15/19 persistent deciduous teeth). Non-age or gender related open apices were most likely associated with mandibular first and second incisor teeth (26/96 teeth with open apices). Tooth resorption was also identified (7/23 pigs). The study findings prove that pet pigs commonly have dental pathology; therefore, thorough oral examinations with intraoral radiographs should be included in porcine routine health care regimens.

ABSTRACT We report here the genome sequences of three African swine fever virus isolates obtained from a domestic pig (Zaire [Zaire]), a warthog (RSA/W1/1999 [South Africa]), and a European wild boar (RSA/2/2004 [South Africa]) belonging to genotypes IV, XX, and XX, respectively. This report increases the number of genotype XX, wild boar, and warthog reference sequences available.

Aim. To provide a complex microbial-zoological characteristics of the postmortem period. Materials and methods: Microbiological studies: material for examination was isolated from three species of animals, including domestic pig (Sus scrofa domesticus) weighing 50-100 kg, domestic chickens (burnt and unburnt) (Gallus gallus) weighing 1.5–2 kg and house mice (Mus musculus) weighing 80 g. In addition, human corpses, bone remains and over 1000 microorganism isolates were investigated. Entomological studies: material for examination was isolated from human corpses and their bone remains (17), pigs (10), chickens (32), representatives of the mammalian class (20), 79 objects in total. 32394 insects were investigated. Studies of injuries caused by certain vertebrates: 34 human corpses and their bone remains were examined. Results. Main trends in the microbial decomposition of dead bodies have been determined, which are of great practical significance for the diagnosis of the remoteness of death during the course of forensic medical examination. General characteristics of the process of corpse decomposition by necrophilous insects are given. The effect of the thermal factor (high temperature) on the microbiological and entomological features of corpse decomposition has been established. Anatomical, topographical and morphological features of injuries caused by some vertebrates have been determined. Conclusion. Our results prove the existence of a close relationship between the objects of forensic medical examination and the microbial processes that occur during the decomposition of corpses and under the action of insects and scavengers.

The Impact

Gastrointestinal parasites are responsible for substantial loss of productivity in livestock production. This study was carried out with the aim of determining the prevalence of gastrointestinal parasites of pigs in Ushongo LGA of Benue State, Nigeria over a period of three months Four hundred fecal samples were collected from the rectum of pigs and screened using the simple tube floatation and tube sedimentation techniques. An overall prevalence of 33.5% was observed. A total of 9 parasite species were isolated. Ascaris, Fasciola, Taenia solium, Trichuris suis, Hymenolepsis, Isospora suis, Strongyloides, Eimeria Spp and Hookworm had a prevalence of 24.17%,16.48%, 19.78%, 6.59%, 1.09%, 3.29%, 18.69%, 6.59%, 3.29%respectively.This study reveals that gastrointestinal parasites are relatively low in Ushongo L.G.A. Further investigation should be carried out to study the impact of parasitic infestation of pigs on public health in the study area.

First Time

Cognitive bias has become a popular way to access non-human animal mood, though inconsistent results have been found. In humans, mood and personality interact to determine cognitive bias, but to date, this has not been investigated in non-human animals. Here, we demonstrate for the first time, to the best of our knowledge, in a non-human animal, the domestic pig ( Sus scrofa domesticus ), that mood and personality interact, impacting on judgement. Pigs with a more proactive personality were more likely to respond optimistically to unrewarded ambiguous probes (spatially positioned between locations that were previously rewarded and unrewarded) independent of their housing (or enrichment) conditions. However, optimism/pessimism of reactive pigs in this task was affected by their housing conditions, which are likely to have influenced their mood state. Reactive pigs in the less enriched environment were more pessimistic and those in the more enriched environment, more optimistic. These results suggest that judgement in non-human animals is similar to humans, incorporating aspects of stable personality traits and more transient mood states.

Abstract Morphometric peculiarities of the development of Оesophagostomum dentatum Rudolphi, 1803 from egg to infective larva were studied under laboratory conditions at various temperatures. The determined optimum temperature for embryonic and post-embryonic development of О. dentatum larvae from domestic pig (Sus scrofa domesticus Linnaeus, 1758) is 22 °С. At this temperature, 81 % of larvae develop to the third stage (L3) on the 10th day. Temperatures of 24 °С and 20 °С are less favorable for the development of the nematode, at those temperatures only 67 and 63 % of larvae, respectively, reached infective stage by the 10th day of cultivation. Embryonic development of О. dentatum eggs is characterized by their lengthening (by 8.87-9.50 %, р < 0.01) and widening (by 6.77-9.35 %, р < 0.05-0.01), and post-embryonic larval development is associated with lengthening (by 4.59-17.33 %, р < 0.01-0.001).
