Porcine Cysticercosis and Risk Factors in The Gambia and Senegal

During a stratified cross-sectional survey, 1705 pigs were sampled from 279 randomly selected households, 63 randomly selected communities and villages, from four study areas in The Gambia and Senegal during the period October 2007 to January 2008. Porcine cysticercosis prevalence detected by tongue inspection at animal level per study area ranged from 0.1% to 1.0%. Using an antigen-detection ELISA the seroprevalence of cysticercosis at both community/village and animal levels for the four selected study areas is: Western region 80.0% (95%CI: 52.4%–93.6%) and 4.8% (95%CI: 3.4%–6.5%), Bignona 86.7% (95%CI: 59.8%–96.6%) and 8.9% (95%CI: 5.0%–15.5%), Kolda 82.4% (95%CI: 46.8%–96.1%) and 13.2% (95%CI: 10.8%–16.0%), and Ziguinchor 81.3% (95%CI: 43.5%–96.1%) and 6.4% (95%CI: 4.0%–10.1%), respectively. No risk factors for cysticercosis were found significant in this study. This study proved that porcine cysticercosis is endemic and distributed widely in the study areas though its incidence might be suppressed by the generalised use of toilets and latrines in the study areas

The Disease Burden of Taenia solium Cysticercosis in Cameroon

Taenia solium cysticercosis is a zoonotic disease occurring in many developing countries. A relatively high prevalence in humans and pigs has been reported in several parts of the world, but insufficient data are available on the disease burden. Disease impact assessment needs detailed information on well-defined epidemiological and economic parameters. Our work conducted in West Cameroon over several years allowed us to collect the necessary information to estimate the impact of the parasite on the human and animal populations in this area using both cost and Disability Adjusted Life Year (DALY) estimations. This study identified the professional inactivity caused by the disease as the major loss factor in comparison to the cost of health care and losses due to infected pigs. These findings should allow a simpler estimation of the global disease burden based on information on salary levels and human cysticercosis prevalence in endemic areas of the world. In addition, the number of DALYs lost was higher than estimates already available for some other neglected tropical diseases in sub-Saharan Africa

Clonal Differences between Non-Typhoidal Salmonella (NTS) Recovered from Children and Animals Living in Close Contact in The Gambia

Salmonellosis is a neglected tropical disease causing serious dysentery and septicaemia particularly in young infants, elderly and immunocompromised individuals such as HIV patients and associated with substantial mortality in developing countries. Salmonellosis also constitutes a major public health problem as it is considered the most widespread bacterial zoonosis of food origin throughout the world. Many epidemiological data exist from developed countries concerning transmission of Non-Typhoidal Salmonella (NTS) but few are available from developing countries. In addition few studies in sub-Saharan Africa have considered the interface between humans and their environment in relation to animals present in the household and food hygiene. This study describes the prevalence of NTS among fourteen Gambian children and 210 domestic animals living in close proximity (household) to the children in a rural setting in The Gambia. We found that the domestic animals living in the same household as patients carried different NTS serovar and genotypes; indicating that zoonotic transmission does not occur in our setting. This study provides baseline data for future studies of transmission of NTS in rural Africa

Becoming the World's Biggest Brewer :Artois, Piedboeuf, and Interbrew (1880-2000)

La 4e de couverture indique :"AB InBev is today's uncontested world leader of the beer market. It represents over 20% of global beer sales, with more than 450 million hectolitre a year flowing all around the world. Its Belgian predecessor, Interbrew, was a success story stemming from the 1971 secret merger of the country's two leading brewers: Artois and Piedboeuf. Based on material originating from company and private archives as well as interviews with managers and key family actors, this isthe first study to explore the history of the company through the nineteenth and twentieth centuries.The story starts in the mid-nineteenth century with the scientific breakthroughs that revolutionised the beer industry and allowed both Artois and Piedboeuf to prosper in a local environment. Instrumental in this respect were the respective families and their successive heirs in stabilizing and developing their firms. Despite the intense difficulties of two world wars in the decades to follow, they emerged stronger than ever and through the 1960s became undisputed leaders in the nationalmarket. Then, in an unprecedented move, Artois and Piedboeuf secretly merged their shareholding in 1971, though keeping their operations separate until 1987 when they openly and operationally merged to become Interbrew.Throughout their histories Artois, Piedboeuf, and their successor companies have kept a controlling family ownership. This book provides a unique insight into the complex history of these three family breweries and their path to becoming a prominent global company, and the growth and consolidation of the beer market through the nineteenth and twentieth centuries."info:eu-repo/semantics/publishe

Bovine cysticercosis: Preliminary observations on the immunohistochemical detection of Taenia saginata antigens in lymph nodes of an experimentally infected calf

A newly developed immunohistochemical test was used for the first time to demonstrate the presence of Taenia saginata (Cysticercus bovis) antigens in the lymph nodes of a heifer calf experimentally inoculated with Taenia saginata eggs. The new test should aid in the differential diagnosis of eosinophilic lymphadenitis in cattle

THE TAENIASIS-CYSTICERCOSIS COMPLEX IN WEST AND CENTRAL AFRICA

Abstract. Taenia solium is present in most of the countries of West and Central Africa with the exception of strict Muslim areas, where pigs are not raised and pork is not eaten for religious reasons. Although the first reports about human and porcine cysticercosis date from the fifties, extensive surveys have only been carried out in a few countries such as Benin, Cameroon, and Togo. However, a lot of case reports and data from small scale surveys are available. Porcine cysticercosis is generally more widespread in Central than in West Africa. In several regions of Central Africa, prevalence figures in pigs of 20 to 30% (based on tongue or meat inspection) are not uncommon. In many West African countries, however, the prevalence of porcine cysticercosis is usually lower than 20% and often below 10%. There are indications that human cysticercosis is also more important in Central than in West Africa. Few data are available on human taeniasis and often no distinction is made between T. solium and T. saginata. Two large scale studies (Togo and Cameroon), in which the tapeworms were identified at the species level, revealed a percentage of about 0.1

Effects of an experimental Trypanosoma congolense infection on the reproductive performance of West African Dwarf goats.

Thirty-six West African Dwarf (WAD) goats were used to assess the effects of an experimental Trypanosoma congolense infection on their reproductive system. Estrous cycles were synchronised and when confirmed pregnant (n = 31), the does were randomly allocated into control and trypanosome-infected groups. After infection, the animals were carefully observed till parturition. Trypanosome infection caused an increase of rectal temperature, a significant drop in PCV (infected: 23.3 +/- 0.3%; control: 28.5 +/- 0.4%; P < 0.0001) and abortions in 27.8% of the infected does. Kids born from infected does had a lower birth weight than kids born from control goats (0.9 +/- 0.1 kg versus 1.6 +/- 0.1 kg; P < 0.0001). Eight out of 13 kids (61.5%) that were born alive from infected does died during their first week of life. Plasma pregnancy-associated glycoprotein (PAG) and progesterone concentrations were lower in the infected animals than in the controls. In general, PAG concentration in does which aborted dropped before abortion. Our results revealed that artificial T. congolense infection affected reproductive performance of WAD goats with abortions, premature births and perinatal losses being observed. Neither transplacental transmission of T. congolense nor histopathological lesions of the placenta could be demonstrated
