AbouLaila, M; El-Bahy, N; Hilali, M; Yokoyama, N; Igarashi, I; 横山, 直明; 五十嵐, 郁男.

This study of enteric parasites of ducks was undertaken to determine their prevalence and the relationships between their prevalence and the age and breed of ducks in the Behera governorate, Egypt. A total of 110 ducks of different ages and breeds were examined. The prevalence of helminths was 4.54% from which the prevalence of nematode, cestode, and trematode infections was 2.72%, 3.63%, and 1.81%, respectively. The recovered nematodes were Ascaridia galli (0.9%) and Heterakis gallinarum (1.81%). The reported trematodes were Echinoparyphium recurvatum (0.9%) and Echinoparyphium paraulum (1.81%). The new reported cestodes were Cladogynia phoeniconaiadis (3.63%), Echinolepis carioca (3.63%), and Baerfainia anoplocephaloides (3.63%). The helminths infections...

Babesia bovis, B. bigemina, Trypanosoma evansi, and Anaplasma marginate infections cause serious diseases in cattle, and are primarily transmitted by arthropod vectors (ticks for B. bovis, B. bigemina, and A. marginate and various types of flies for T. evansi). In the last few years, there have been many reports of a high prevalence of certain protozoan infections in northern Egypt, but no accurate or adequate data are available for the southern regions. Therefore, in this study, we screened for evidence of such diseases in economically important cattle species using serum samples. The seroprevalence of protozoan infections in cattle was determined with enzyme-linked immunosorbent assays using species-specific diagnostic antigens. In a total of 301 cattle...

Serodiagnosis of Toxoplasma gondii in ducks from Behera Governorate, Egypt

Serological detection and epidemiology of Neospora caninum and Cryptosporidium parvum antibodies in cattle in southern Egypt

AbouLaila, M; El-Bahy, N; Hilali, M; Yokoyama, N; Igarashi, I; 横山, 直明; 五十嵐, 郁男.

Toxoplasma gondii is an important zoonotic parasite. The diagnosis of infection in animals is an important tool to prevent human infection. In the present study, Toxoplasma gondii was diagnosed by using the modified agglutination test (MAT) in ducks from Behera Governorate, Egypt. The prevalence of Toxoplasma gondii was 13.9%. The prevalence of Toxoplasma gondii was the highest in the Native breed (17.65%) and in 6-8-months age group (19.4%). End-point titer of 1:25, 1:50, and 1:100 were recorded in 61.9%, 19.05%, and 19.05% of the positive samples, respectively. Duck meat is one source of the Toxoplasma gondii infection for human in Egypt.

Neospora caninum and Cryptosporidium parvum are intracellular protozoan parasites that are distributed worldwide and of major economical concern in cattle industry. N. caninum can cause abortion storms and high culling rates, whereas C. parvum has zoonotic implications and can cause diarrhea in calves. There are currently no data on the prevalence of neosporosis and cryptosporidiosis in humans or animals in southern Egypt. Prevalence of these two infections was determined in a sample of cattle from two different areas in southern Egypt, Sohag and Qena, using enzyme-linked immunosorbent assay. A total 301 cattle were sampled, of which 18.9% were positive for N. caninum, 35.9% were positive for C parvum and 10.0% were positive for both. Geographical location...

Toxoplasmosis is a cosmopolitan protozoan disease that has been recorded in a wide range of vertebrate hosts, including humans. In response to the paucity of available data, this study was undertaken to comprehensively establish the seroprevalence of Toxoplasma gondii among various farm animals in different localities of Egypt. The latex agglutination test and TgGRA7-based enzyme-linked immunosorbent assay were used to screen the investigated animals for anti-T. gondii IgG antibodies. When only samples with simultaneously positive results for both the latex agglutination test and the TgGRA7-based ELISA were considered positive, 174 (26.7%) of 652 serum samples from different animals were seropositive. The prevalence of antibodies according to species was:...

The demand for meat in Egypt: An almost ideal estimation

Alboghdady, Mohamed Altabei; Alashry, Mohamed Khairy.

This paper analyzes the demand for meat in Egypt for the period 1990–2005 using the linearized Almost Ideal Demand System to estimate own-price, cross-price and expenditure elasticities. It found that the Marshallian own-price elasticity was the highest for fish, followed by chicken, beef and duck. On the other hand, the crossprice elasticity of beef showed a complementary relationship with the other meat types, except for fish, which is substitutive. Chicken and fish showed a substitutive relationship with all other meat types. Duck showed a substitutive relationship with all meats except rabbit. Mutton and rabbit showed a versatile relationship with the other meat types. The highest substitutive relationship was between mutton and beef. Compensated...

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia

Kim, Ungtae; Kaluarachchi, Jagath J.; Smakhtin, Vladimir U..

The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Adjustment of Wheat Production to Market Reform in Egypt

Kherallah, Mylene; Minot, Nicholas; Gruhn, Peter.

In response to slow growth in the agricultural sector and as part of a general shift towards a more market-oriented economy, the Government of Egypt started liberalizing the agricultural sector in 1987. Controls over wheat production and marketing were eliminated and wheat producer prices were brought closer to international levels. As a result, there has been remarkable increases in wheat crop area and yields, causing wheat production to triple from 1986 to 1998. This study analyzes the results of a survey of 800 Egyptian wheat farmers in order to address three issues that are of interest to agricultural reform policy in Egypt. First, what are the patterns in wheat production and marketing that have emerged following the economic reforms? Second, why is...

Fabiosa, Jacinto F..

This study characterizes the household food-away-from-home (FAFH) expenditure pattern in Egypt. Specifically, a standard Tobit model was estimated to quantify the responsiveness of Egyptian household FAFH expenditures to changes in their income and selected household demographic characteristics. We found that the proportion of households with a positive FAFH expenditure is small, at 36% to 38% of the total number of households. These households spent 5% to 8% of their total expenditure on FAFH. Households that are located in urban areas, with more family members, and whose household head is young and male had generally higher levels of FAFH expenditure. The estimated conditional income elasticity is only 0.02, and the unconditional income elasticity is...

Addressing longer-term issues of economic development in Egypt, the paper employs a dynamically recursive computable general equilibrium (CGE) model to assess the outcomes associated with two types of development approaches over the period 1998-2012. One is a targeted sector development approach, and the second is a more broad-based development approach. Under the first development approach technological advancement is separately targeted to three sectors: agriculture, food processing, and textiles. Each sectoral choice is intended to represent alternative development strategies which we label (i) agricultural-demand- led industrialization (ADLI); (ii) food-processing-based (FOOD); and (iii) textile-based industrialization (TEXTILE). Under the second...

The paper shows how, when the enforceability of regulations is size-sensitive, price competition can lock firms into informality and, thus, smallness, depending on the form of the production function. In that context, exogenours "help"packages targeted to informal firms "promote" micro and small enterprises (i.e., increase their numbers) but do not "develop" them (i.e., foster their growth). The "help" only generates a short-term span of abnormal profits for existing informal firms, and a long-term income transfer toward informal-market consumers. The model is tested in the context of Egypt's micro and small enterprise sector.

China's and India's rapid rise in the global arena has not only captured the attention of the world but has also set into motion a rethinking of the very paradigm of economic development. Today, China and India together account for 40 percent of the world's population. Both have implemented a series of economic reforms in the past two and half decades: China initiated this process at the end of the 1970s, while India began in the early 1990s. These reforms have led to rapid economic growth, with a growth rate of 8-9 percent per annum in China and 6-7 percent per annum in India. Despite similar trends in the reforms, the two countries have taken different reform paths; China started off with reforms in agriculture sector and in rural areas, while India...

Determinants of the Adaption of Organic Agriculture in Egypt Using a Duration Analysis Technique

Adams, Richard H., Jr..

Many low-income people, especially those from poor rural areas, seek to improve their lives by immigrating in search of work and income, increasingly moving across national borders and further afield. In recent years, the remittances they earn have come to have an important effect on the economies of many developing countries, profoundly affecting poverty, income distribution, and rural economic development in the villages from which the migrated. The results of this study compliment the findings of other IFPRI studies on poverty alleviation, income sources, and rural development. The study uses primary household data from small area of rural Egypt in a innovative way to address such vital questions as who immigrates, how remittances affect poverty and...
