Validation of Loop-Mediated Isothermal Amplification (LAMP) Field Tool for Rapid and Sensitive Diagnosis of Contagious Agalactia in Small Ruminants
2020
Simple Summary Contagious agalactia (CA) is an infectious disease of small ruminants endemic in the Mediterranean countries, causing significant socioeconomic impacts predominantly on small-scale farmers who still subsist on marginal lands. Mycoplasma agalactiae is historically considered the principal etiological agent of CA, especially in sheep. Clinical signs are characterised by mastitis, arthritis, keratoconjunctivitis and occasionally, abortion. Rapid, accurate and cost-effective field tests are urgently needed for effective control of M. agalactiae mastitis. Our study illustrated the validation of a Loop-Mediated Isothermal Amplification (LAMP) test for the detection of M. agalactiae…
Prevalency of Nematode in Bali Cattle at Manokwari Regency
2015
This study was conducted from August to October 2006, a disease caused by worms digestive tract is one of the causes of the decline in beef production . The purpose of this study was to assess the number of infected cattle nematode, the nematode types and amount of each type of nematodes in Bali cattle in Manokwari. Based onobservations on the worm eggs, total of 23 individuals (44.23 %) of Bali cattle ( puppies and adults ) infected with nematodes. Most of the infected cow is a cow that as many as 16 puppies cattle (69.56 %), while the remaining 7 animals (30.44 %) is the mother cow. Types of nematodes that infect cattle puppies and adult cattle are Cooperiasp., Bunostomum sp., Mecistocirr…
Comment on "Epidemiological Survey on Porcine Cysticercosis in Nay Pyi Taw Area, Myanmar".
2015
We have read with interest the paper by Khaing et al. [1], in which first data on Taenia solium cysticercosis in pigs from Myanmar are published. The authors found a porcine cysticercosis prevalence of 23.67% in slaughtered pigs, which, as they mention, indicates the presence of human taeniasis and also the risk of acquiring human cysticercosis and, therefore, neurocysticercosis. The high porcine cysticercosis prevalence detected by the authors means, obviously, that there has to be a high prevalence of human T. solium taeniasis among the inhabitants of Myanmar leading to a high presence of infective eggs in the environment. However, as far as we know, the presence of T. solium taeniasis, a…
Evidence for Transmission of Taenia solium Taeniasis/Cysticercosis in a Rural Area of Northern Rwanda
2021
Cysticercosis is a parasitic infection caused by the metacestode larval stage (cysticercus) of Taenia solium. In humans, cysticercosis may infect the central nervous system and cause neurocysticercosis, which is responsible for over 50,000 deaths per year worldwide and is the major cause of preventable epilepsy cases, especially in low-income countries. Cysticercosis infection is endemic in many less developed countries where poor hygiene conditions and free-range pig management favor their transmission. A cross-sectional study was conducted in 680 children from a rural primary school in Gakenke district (Northern province of Rwanda). Stool samples were collected from participants and analy…
Ping-pong configurations and circular orders on free groups
2017
We discuss actions of free groups on the circle with "ping-pong" dynamics; these are dynamics determined by a finite amount of combinatorial data, analogous to Schottky domains or Markov partitions. Using this, we show that the free group $F_n$ admits an isolated circular order if and only if n is even, in stark contrast with the case for linear orders. This answers a question from (Mann, Rivas, 2016). Inspired by work of Alvarez, Barrientos, Filimonov, Kleptsyn, Malicet, Menino and Triestino, we also exhibit examples of "exotic" isolated points in the space of all circular orders on $F_2$. Analogous results are obtained for linear orders on the groups $F_n \times \mathbb{Z}$.
Teichmuller Space and Related Topics : Proceedings of the workshop on Geometry, January 20, 2011, JOSAI UNIVERSITY
2012
The theory of geometric structures on a surface with nonempty boundary can be developed by using a decomposit,ion of such a surface into hexagons, in the same way as the theory of geometric structures on a surface without boundary is developed using the decomposition of such a surface into pairs of pants. The basic elements of the theory for surfaces with boundary include the study of measured foliations and of hyperbolic structures on hexagons. It turns out that there is an interesting space of measured foliations on a hexagon, which is equipped with a piecewise-Iinear structure (in fact, a natural cell-decomposition), and this space is a natural boundary for the space of hyperbolic struct…
On the classification of mapping class actions on Thurston's asymmetric metric
2011
AbstractWe study the action of the elements of the mapping class group of a surface of finite type on the Teichmüller space of that surface equipped with Thurston's asymmetric metric. We classify such actions as elliptic, parabolic, hyperbolic and pseudo-hyperbolic, depending on whether the translation distance of such an element is zero or positive and whether the value of this translation distance is attained or not, and we relate these four types to Thurston's classification of mapping class elements. The study is parallel to the one made by Bers in the setting of Teichmüller space equipped with Teichmüller's metric, and to the one made by Daskalopoulos and Wentworth in the setting of Te…
Defining gut mycobiota for wild animals: a need for caution in assigning authentic resident fungal taxa
2021
Animal gut mycobiota, the community of fungi that reside within the gastrointestinal tract, make an important contribution to host health. Accordingly, there is an emerging interest to quantify the gut mycobiota of wild animals. However, many studies of wild animal gut mycobiota do not distinguish between the fungi that likely can reside within animal gastrointestinal tracts from the fungal taxa that are non-residents, such as macrofungi, lichens or plant symbionts/pathogens that can be ingested as part of the host’s diet. Confounding the non-resident and resident gut fungi may obscure attempts to identify processes associated with the authentic, resident gut mycobiota per se. To redress th…
Untargeted metabolomics of rind essential oils allowed to differentiate two closely related clementine varieties
2021
[EN] Chemical characterization of clementine varieties (Citrus clementina Hort. ex Tan.) essential oils (EO) can lead to variety identification and valorization of their potential use in food and aroma industries. The goal of this study was the chemometric discrimination between two very closely related and morphologically identical clementine varieties, Clemenules (NL) and Clemenpons (PO), based on their rind EO, to identify the differential volatile organic compounds (VOCs) and to determine their antioxidant capacity. EO rind volatile profile was determined by gas chromatography coupled to mass spectrometry in Citrus fruit at different ripening stages grown two independent years in two di…
