Cryptosporidium is comprised an apicomplexan parasitic protist, which infects a wide range of hosts, causing cryptosporidiosis. In cattle farms, the incidence of cryptosporidiosis results in high mortality in calves leading to considerable economic loss in the livestock industry. Infected animals may also act as a major reservoir of Cryptosporidium spp., in particular C. parvum, the most common cause of cryptosporidiosis in calves. This poses a significant risk to other farms via breeding centres, to trading of livestock and to human health. This study, funded by the Interreg-2-seas programme, is a part of a global project aimed at strategies to tackle cryptosporidiosis. To reach this target, it was essential to determine whether prevalence was dependent on the studied countries or if the issue was borderless. Indeed, C. parvum occurrence was assessed across dairy farms in certain regions of Belgium, France and the Netherlands. At the same time, the animal-to-animal transmission of the circulating C. parvum subtypes was studied. To accomplish this, 1084 faecal samples, corresponding to 57 dairy-farms from all three countries, were analysed. Well-established protocols amplifying the 18S rDNA and gp60 genes fragments, followed by DNA sequencing, were used for the detection and subtyping C. parvum; the DNA sequences obtained were further characterised using a combination of bioinformatics and phylogenetics methods. Our results show 25.7%, 24.9% and 20.8% prevalence of Cryptosporidium spp. in Belgium, France and the Netherlands respectively. Overall, 93% of the farms were Cryptosporidium positive. The gp60 subtyping demonstrated a significant number of the C. parvum positives belonged to the IIa allelic family, which has been also detected in humans. Consequently, this study highlights how widespread is C. parvum in dairy farms and endorses cattle as a major carrier of zoonotic C. parvum subtypes, which subsequently pose a significant threat to human health.

Health Significance

The importance of brucellosis is primarily due to its public health significance and economic loss for the animal industry. The present study was performed to determine the seroprevalence of brucellosis in man and animals. A total of 1,452 samples (cattle 913, buffaloes 99, sheep 40, goats 50 and persons 350) were collected from Central Cattle Breeding and Dairy Farms, Savar, Dhaka and 5 districts (Mymensingh, Jamalpur, Gaibandha, Rangpur and Bagerhat) of Bangladesh. All samples were screened by RBT and the RBT positive sera were re–tested with SAT CFT, ELISA and qRT-PCR. Out of 913 cattle and 99 buffalo sera, 48 cattle and 7 buffalo sera showed positive reaction to RBT i.e. prevalence of brucellosis is 5.3% in cattle and 7.1% in buffaloes. The 350 human sera and all sheep and goats samples were negative to RBT. Among the RBT positive sera, 12 sera were found to contain Brucella DNA by genus specific IS711 quantitative real time PCR (qRT-PCR); and all PCR positive samples were found to contain Brucella abortus DNA. This report confirms that B. abortus is endemic in cattle and buffaloes in Bangladesh.

Crops are the main victims of the accident of water pollution. The paper will discuss treatment program,investigation, crop damage symptom recognition, direct economic loss estimation of water pollution, confirmation, accident responsibility partition and arbitration of such links. It will provide principles for the other accidents. Besides, it can also be used as a handling reference to other issues of pollution and pollution accident.

Intensive systems of milk production in Brazil and Holland are compared by SWOT analysis. Twenty-one farms, 10 in Wageningen, central region of Holland, and 11 in Castro, central-eastern region of the state of Paraná, Brazil, were sampled. Data were retrieved from semi-structured interviews with the owners or people responsible for dairy activities, using a questionnaire guide and a digital recorder. After results were analysed, a table was elaborated representing the strengths, weaknesses, opportunities and risks for each country. Dairy farms in Holland were uniform, or rather, small and medium-sized farms with high production. It has also been observed that Dutch farms have several problems due to high intensification, for example, hoof diseases with great economic loss. In the case of Brazilian dairy farms, several types of systems and degrees were detected. Brazilian production in the region analysed features a higher quantity than that in Holland, with less intensity when compared to that on Dutch farms.
