Socio-economic indicators of the camel production sector in southeast Tunisia: main households survey results

This Socio-economic study has been conducted by a team of PROCAMED Project. This project falls within the framework of the promotion of the innovating camel systems and of the local camel value chains for a sustainable management of the Saharan territories. The socio-economic survey was conducted in four regions of southeast Tunisia (Medenine, Tataouine, Gabes and Kebeli). A total of 147 households were interviewed on the management, significance and constraints associated to the camel production in the area using a field diagnostic survey. According to the camel breeders' responses, the family living status of the camel herders has based on camels and small ruminant's livestock activities. Most of the camel herders were keeping areas occupied by natural vegetation which can provide a feed source for animals. For the most part of the areas have an average annual rainfall below 300 mm and either a Saharan or an arid Mediterranean bioclimate. Although the land ownership status may change, the rangelands are mostly subject to the system known as collective ownership. Major source of income of the camel herders at all zones were sale of milk and meat, sale of animals and crop cultivation. Majority of the herders kept their camels in open air system and take their camels for grazing from morning till evening at all the zones. But, because of rangelands degradation the trend of supplementation becoming more and more adopted. Camels play an important role in the socio-economics of the people in this area. In order to improve the camel production in the study area, Livestock and dairy development department and local public services, should take into consideration the importance of camel and the prevalent problems in the area.

Low milk cholesterol in camel milk: true or not?

Many authors argue that camel milk contains less cholesterol than cow milk while other reported the reverse. To compare the cholesterol content in camel and cow milk in similar farming conditions and to assess the impact of short underfeeding on cholesterol concentration in milk and serum, seven cows and seven camels were sampled (milk and blood) at the middle of lactation at morning and evening milking, then two weeks after distribution of low energy-protein diet, another sampling was achieved. Cholesterol content in camel milk (5.64 +- 3.18 mg 100g-1) was lower than in cow (8.51 +- 9.07 mg 100g-1), but the difference was not significant. Moreover, the ratio cholesterol/fat was similar in the two species (225 +- 125 mg 100g-1 fat in camel and 211 +- 142.4 mg 100g-1 fat in cow). Serum cholesterol concentration was significantly higher in cow (227.8 +- 60.5 vs 106.4 +- 28.9 mg 100mL-1). There was significant difference between morning and evening milking in milk fat composition and concentrations in cholesterol. The present study showed that cholesterol concentration in camel serum is lower than in cow in similar feeding and environmental conditions, but further researches are needed to demonstrate the relationship between feeding and cholesterol content in camel milk.

MERS-CoV (Middle East Respiratory Syndrome Coronavirus) outside the Arabian Peninsula an One Health approach: Understanding the role of wildlife, livestock and human in the virus dynamic

One of the big paradoxes of the MERS-CoV epidemiology is the apparent lack of human cases in large parts Africa where the virus and an animal host, the dromedary camel, are present. Understanding the differences between Africa and the Arabian Peninsula (where MERS-CoV is now endemic) would provide crucial understanding on how to reduce zoonotic infection. We set up field protocols for estimating (i) the prevalence of MERS-CoV infection in camel populations and other sensitive species outside Arabian Peninsula, (ii) the 'at risk' farming practices that facilitate transmission between camels, (iii) infection variation pattern in both camels and humans. The first project phase consisted in a descriptive serological and virological mapping of MERS-CoV in Africa and central Asia in camel populations (i.e. dromedary and Bactrian).The second project phase consists in a longitudinal epidemiological monitoring (monthly time step) in camel populations from Morocco and Ethiopia (blood, swabs, urine, milk); complemented by a questionnaire based survey of camel owners' practices. Finally, in parallel a cross-sectional sero-prevalence survey in human, particularly camel owners and animal workers in abattoirs is conducted by the Institut Pasteur in Morocco. A cross-sectional sero-prevalence survey is e also conducted on bats in houses and 'oasis' close to farms in Ethiopia. Addressing these questions is crucial for developing recommendations for animal and human health institutions and countries

Camel meat marketing and camel meat marketplace in the Algerian northern Sahara-case of the region of Souf

A field survey involving 62 camel butchers from Souf region the Algerian northern Sahara was implemented in order to establish a typology of camel butcher and collect data on camel meat marketing, the diversity in marketing practices and camel meat marketplace. The collected data allowed to identify 4 homogeneous groups of butchers well distinguished between them after cluster analysis. (specialized young camel butchers, non-specialized rural butchers, traditional non-specialized urban butchers, modern and old urban specialized butchers). The present study confirmed the predominance of beef meat compared to camel meat among consumers, camel meat consumption being less successful in its environment. In-depth studies on camel meat sector are mandatory to identify the bottlenecks invalidating the promotion of the camel meat consumption

A CAMEL rating's shelf life

How quickly do the CAMEL ratings regulators assign to banks during on-site examinations become "stale"? One measure of the information content of CAMEL ratings is their ability to discriminate between banks that will fail and those that will survive. To assess the accuracy of CAMEL ratings in predicting failure, Rebel Cole and Jeffery Gunther use as a benchmark an offsite monitoring system based on publicly available accounting data. Their findings suggest that, if a bank has not been examined for more than two quarters, off-site monitoring systems usually provide a more accurate indication of survivability than its CAMEL rating. The lower predictive accuracy for CAMEL ratings “older” than two quarters causes the overall accuracy of CAMEL ratings to fall substantially below that of off-site monitoring systems. The higher predictive accuracy of off-site systems derives from both their timeliness—an updated off-site rating is available for every bank in every quarter—and the accuracy of the financial data on which they are based. Cole and Gunther conclude that off-site monitoring systems should continue to play a prominent role in the supervisory process, as a complement to on-site examinations.bank; bank failure; CAMEL; CAMEL rating; commercial bank; offsite supervision

Molecular and morphological characterization of Echinococcus granulosus of human and animal origin in Iran

Iran is an important endemic focus of cystic hydatid disease (CHD) where several species of intermediate host are commonly infected with Echinococcus granulosus. Isolates of E. granulosus were collected from humans and other animals from different geographical areas of Iran and characterized using both DNA (PCR-RFLP of ITS1) and morphological criteria (metacestode rostellar hook dimensions). The sheep and camel strains/genotypes were shown to occur in Iran. The sheep strain was shown to be the most common genotype of E. granulosus affecting sheep, cattle, goats and occasionally camels. The majority of camels were infected with the camel genotype as were 3 of 33 human cases. This is the first time that cases of CHD in humans have been identified in an area where a transmission cycle for the camel genotype exists. In addition, the camel genotype was found to cause infection in both sheep and cattle. Results also demonstrated that both sheep and camel strains can be readily differentiated on the basis of hook morphology alone

River Camel SAP Final Plan

This is the River Camel Salmon Action Plan Final document produced by the Environment Agency in 2002. This final Salmon Action Plan (SAP) for the River Camel catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Camel salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Camel

The Camel Corps Experiment

“Did you know there was a push to create a Camel Corps right before the beginning of the American Civil War?” This certainly seems like an interesting piece of trivia to share around the dinner table, but what was the Camel Corps and what insights can it provide on U.S. military thinking in the mid-19th century? I believe that the Camel Corps Experiment, regardless of whether it was deemed an utter failure or not, demonstrated progressive military thought and the desire of its advocates to explore advancements in both mobility and technology for military practices.

Camel Anatomy; More Than Just a Hump

The one-humped camel (Camelus dromedarius) is capable of living in extreme, arid environments due to its numerous anatomical adaptations. Its modified features of the muscular system, integument, skeletal system, and several internal organs allow this animal to survive in such harsh environmental conditions. Many of these adaptations allow for conservation of energy and water as well as improvement of locomotion to acquire scarce resources. In this paper we will look more closely at some of these adaptations and determine their function in promoting the survival and reproduction of the one-humped camel in desert environments

Performance analysis of anaplasma antibody competitive ELISA using the ROC curve for screening of anaplasmosis in camel populations in Egypt

Anaplasmosis is a tick-born and potential zoonotic disease caused by Anaplasma (A.) phagocytophilum, A. ovis, A. platys and A. capra. Anaplasma marginale affecting bovines and camels causing significant economic losses. Camels as an integral part of the socio-economic lifestyle of nomads in semi-arid to arid ecosystems are prone to suffer from subclinical Anaplasma infections. This study aimed to determine the performance and adaptation of commercial competitive Anaplasma ELISA (cELISA) as a tool for screening the seroprevalence of anaplasmosis whitin the camel populations in Egypt. This study was based on the serological investigation of 437 camel sera collected between 2015 and 2016 during a Q fever prevalence study in Egypt using commercially available cELISA for the detection of antibodies specific for Anaplasma in bovine serum. The receiver operating characteristic (ROC) curve, an analysis method for optimizing cutoff values in cELISAs, was used to estimate the sensitivity and specificity using 76 true as serological positive (n = 7) and negative (n = 60) for Anaplasma antibodies. ROC curve analysis was done for 7 true positive and 60 true negative bovine samples and 7 true positive and 29 true negative camel samples serum. Real time PCR and/or conventional PCR was applied to confirm Anaplasma spp. specific-DNA in camel serum as an indication of a true positive and true negative for ROC analysis. Chi square analysis was performed to estimate the association between risk factors and anaplasmosis in camels. The cutoff value was determined as 0.42 (p value ≤ 0.001). Data simulation with randomly generated values revealed a cutoff value of 0.417 (p ≤ 0.001) with resulting 58.1% Se and 97.8% Sp. Seven true positive and 29 true negative camel serum samples was confirmed by PCR. Using the estimated cut off, the seroprevalence in the Nile Valley and Delta and the Eastern Desert domain was 47.4% and 46.4%, respectively. The potential risk factors as domains and origin of animals were less significantly associated with the prevalence of anaplasmosis (domains: χ(2) = 41.8, p value ≤ 0.001 and origin: χ(2) = 42.56, p value ≤ 0.001). Raising awareness especially for veterinarians and animal owners will significantly contribute to the best understanding of anaplasmosis in camels in Egypt. Alternative (in silico) validation techniques and preliminary prevalence studies are mandatory towards the control of neglected anaplasmosis in the camel population
