to investigate the prevalence of cryptosporidium infection in horses, a total of 200 fecal specimens were collected randomly from five farms in tehran. samples were taken during a year, 50 specimens each season. of these specimens, 57 were obtained from caspian pony. the presence of oocysts in the samples was confirmed by modified ziehl-neelsen staining of direct smears of the fecal material fr...

The Ponto-Caspian mysid shrimp Hemimysis anomala was found in Ireland for the first time in April 2008. During 2009 it was found throughout most of the Shannon River Navigation (~250km) occurring in swarms at estimated densities of ~6 per litre in shallows and in lower densities at depths of ~20m where its distribution overlaps with the native Mysis salemaai. Broods were found from March to Sep...

The present study was designed to characterize phenotypically and genotypically seven Arcanobacterium haemolyticum strains obtained from infections of six horses. All seven strains showed the cultural and biochemical properties typical of A. haemolyticum and were susceptible to most of the antibiotics tested. The species identification could be confirmed by amplification and sequencing of the 1...

The objective of the present study was to determine clinical and arthroscopic characteristics associated with dorsoproximal proximal phalanx (P1) fragments in Warmblood horses, as well as to examine their histopathological appearance. One hundred sixty-eight fragments were removed from 150 fetlocks of 117 Warmblood horses. Details of signalment and results of clinical examination were collected...

Salivary proteins of Culicoides biting midges are thought to play a key role in summer eczema (SE), a seasonal recurrent allergic dermatitis in horses. The present study describes the identification, expression and clinical relevance of a candidate allergen of the North American midge Culicoides sonorensis. Immunoblot analysis of midge saliva revealed a 66 kDa protein (Cul s 1) that was bound b...

We characterized the scintigraphic and sonographic appearance of the thyroid gland in clinically normal horses to establish the value of these modalities for assessment of the thyroid gland in this species. Horses were divided into two age groups. One group consisted of eight horses between 3 and 10 years of age and the other of seven horses between 11 and 20 years of age. Total T4 concentratio...

After the 1999 outbreak of West Nile (WN) encephalitis in New York horses, a case definition was developed that specified the clinical signs, coupled with laboratory test results, required to classify cases of WN encephalitis in equines as either probable or confirmed. In 2000, 60 horses from seven states met the criteria for a confirmed case. The cumulative experience from clinical observation...

This paper is focused on the discussion of the exact age, and environmental setting of the ‘Khvalynian’ Transgression of the Caspian Sea with the use of novel radiometric, isotopic evidence and GIS-linked modelling. Based on this evidence the Khvalynian transgression is viewed as coeval with the warm Late Glacial episodes in the higher latitudes, reaching its peak at 13.6 11.8 ka. During that p...

The Childhood and Adolescence Surveillance and PreventIon of Adult Non-communicable disease (CASPIAN) study is implemented in the Islamic Republic of Iran from 2003. The aim of this national school- based surveillance program was to provide accurate data of regular surveys of this program to be reviewing methodology, protocols, data collection and questionnaires of these surveys. Information wa...
