AbstractA 6-year retrospective study based on abattoir records was carried out to determine the prevalence of hydatidosis in dromedaries in Khorasan province in north–eastern Iran. Between 20 March 2004 and 19 March 2010, 25,255 dromedaries were slaughtered in the study area and the livers of 2791 (11.1%) and the lungs of 3289 dromedaries (13.2%) were discarded due to hydatidosis. The annual prevalence of liver condemnations due to hydatidosis decreased from 24.1% in 2004–2005 to 13.3% in 2009, and finally to 6.8% in 2010. The corresponding features for lung condemnation due to hydatidosis were relatively higher than liver, declining from 28.7% in 2004–2005 to 14.9% in 2009, and finally to 7.1% in 2010. Liver and lung condemnations due to hydatidosis were significantly higher in the spring. This could be attributed to various factors such as sources of slaughtered animals, changes in management practice and ecological factors. The present survey provides baseline data for the future monitoring of this potentially important parasitic disease in the region.

AbstractA 6-year (2004–2010) retrospective study was carried out to determine the prevalence of hydatidosis in livestock slaughtered in Mashhad abattoir, Mashhad, in north-eastern Iran and the capital of Khorasan province. Between 20 March 2004 and 19 March 2010, 5,131,485 animals (411,163 cattle; 4,547,618 sheep; 172,704 goats) were slaughtered in the study area and 388,399 (7.5%) livers and 1,139,529 (22.2%) lungs were discarded. Hydatidosis was responsible for 4% and 6.5% of total livers and lungs inspected, respectively. Of the cattle livers and lungs inspected over the survey period, 5.5% and 7.9% were condemned, respectively, because they held hydatid cysts. The corresponding values for livers and lungs of sheep (2%, 4%) and of goats (4.5%, 7.8%), respectively, were also condemned due to hydatidosis. Data showed a prominent seasonal pattern for hydatidosis. Liver condemnations due to hydatidosis were higher in winter and autumn for cattle and sheep, respectively, whereas lung condemnations were higher in summer for sheep and cattle. In goats, liver and lung condemnations were higher in winter. This could be attributed to various factors, such as sources of slaughtered animals, changes in management practice and ecological factors. The present survey provides baseline data for the future monitoring of this potentially important parasitic disease in the region.

Direct Economic Losses

A retrospective study was conducted to investigate the prevalence of bovine tuberculosis and direct economic losses (DEL) from tuberculosis in cattle slaughtered in Makurdi abattoirs from 2008 to 2012, using abattoir records obtained from the Ministry of Agriculture and Natural Resources. Out of 61654 cattle slaughtered during the study period 1172 (1.90%) were positive for tuberculosis lesions. The annual prevalence of bovine tuberculosis ranges from 0.90% in 2008 to 4.04% in 2012. There was significant (P<0.05) difference in annual prevalence of bovine tuberculosis. It was also observed that there was no seasonal difference in the prevalence of bovine tuberculosis. A total of 1935 affected organs by BTB weighing 3046.50 kg, amounting to 2.91 × 106 Naira (1.82 × 104 USD), were condemned within the study period. Seasonal variation in organ condemnation due to bovine tuberculosis was significantly different (Mann-WhitneyUstatistics = 774 × 103,P=0.034). It was concluded that bovine tuberculosis is prevalent in Makurdi and accounts for heavy economic losses due to condemnation of edible organs.

The One

The following is a preliminary report on the results achieved during approximately six weeks' archaeological fieldwork in north-eastern Iran in July and August 1963. The primary objective was to explore the area for traces of the local Upper Pleistocene cultural sequence, and in particular to establish if possible the date and character of the local Upper Palaeolithic. In the event no traces of Upper Palaeolithic were obtained. However, a start was made towards defining the problem by the discovery of two well-stratified deposits, the one yielding a Middle Palaeolithic (Mousterian) industry with distinctive regional affinities, and the other an early Post-glacial Mesolithic industry. Reliable samples were obtained for defining the statistical properties of both, together with carbon samples, traces of vertebrate fauna, and some other climatic data.Representative collections were lodged with the Musée Iran Bastan at Teheran; and the expedition's share is to be offered in part to the Museum of Archaeology and Ethnology in Cambridge and in part to the British Museum. The expedition was financed mainly by a grant from the British Academy, supplemented by further grants from the Crowther-Beynon Fund and the British Museum.

SUMMARYPrevalence and abundance ofBartonellaspp. infections were studied over a 3-year period in woodland and grassland rodents in North-Eastern Poland. Prevalence of bacterial infections was similar in the two rodent communities, with one leading host species in each habitat (46·3% inApodemus flavicollisversus 29·1% inMyodes glareolusin forest, or 36·9% inMicrotus arvalisversus 13·7% inMi. oeconomusin grassland). Prevalence/abundance of infections varied markedly across the 3 years with 2006 being the year of highest prevalence and abundance. Infections were more common during autumn months inMy. glareolusandA. flavicollis, and in juvenile and young adult (age classes 1 and 2)My. glareolusandMi. oeconomusthan in adults (age class 3). Higher prevalence and abundance ofBartonellainfections were found in maleA. flavicollisin comparison to females. These data are discussed in relation to the parasite genotypes identified in this region and with respect to the role of various ecological factors influencingBartonellaspp. infections in naturally infected host populations.
