The genus Campylobacter  is of great importance to public health because it includes several species that may cause diarrhoea. Poultry and poultry products are known as important sources of human campylobacteriosis. In this study, during the autumn months of 2005, a total of 100 samples from poultry carcasses, representing 20 broiler flocks were obtained by rinse test, after the chilling stage ...

To study the epizootiology of malignant catarrhal fever viruses (MCFV), serum and spleen samples collected in 2004-2011 from a free-ranging musk ox (Ovibos moschatus) population in Dovrefjell, Norway, were examined. Sera were tested for antibodies against MCFV by competitive enzyme-linked immunosorbent assay and spleen samples were examined by a consensus polymerase chain reaction (PCR) for her...

An experimental study was conducted to evaluate the potential presence of porcine circovirus type 2 (PCV2) in the semen of infected boars. Four mature boars were inoculated intranasally with PCV2 isolate LHVA-V53 propagated on PK15 cells. Two boars inoculated with the supernatant of noninfected PK15 cells were kept as controls. Serum samples were collected from all boars at 4, 7, 11, 13, 18, 21...

A total of 123 water samples were examined in parallel by culture and semi-nested PCR for the presence of Legionella. They comprised: 35 samples of hot water distributed by the urban municipal water supply system (MWSS) taken in institutions, 45 samples of hot water distributed by urban MWSS taken in dwellings, 27 samples of cold water distributed by rural MWSS taken in dwellings, and 16 sample...

African swine fever (ASF) epizootic outbreaks often result in the deaths of large numbers either through confirmed or suspected disease depopulation for outbreak control. Identification effective biosecure livestock mortality disposal methods, capable inactivating ASF virus (ASFV) contaminated carcasses, remains an important component development localized response and recovery plans. In this s...

OBJECTIVE To clarify the relationship between enteroviral infection and febrile seizures. STUDY DESIGN Cerebrospinal fluid (CSF), serum, throat swab, and rectal swab samples were collected for virologic examination from 67 children with febrile seizures from April 1997 to March 1999. Those samples were examined for the presence of enterovirus using cell culture and 2 polymerase chain reaction...

background: toxoplasmosis is a worldwide spread disease. the present study examined the prevalence of toxoplasma gondii infection among animals of ediblemeat (cattle and sheep) in chaharmahal va bakhtiari province (southwest of iran) in 2012. furthermore, we attempted for the first time to identify this parasite from the meat products in the province. methods: the tongue, brain, femur muscle an...

background : acanthamoeba- bacteria interactions enable pathogenic bacteria to tolerate harsh conditions and lead to transmission to the susceptible host. the present study was aimed to address the presence of bacterial endosymbionts of acanthamoeba isolated from recreational water sources of tehran, iran. to the best of our knowledge this is the first study regarding occurrence of bacteria in ...

Abstract Background and Aims: Hop stunt viroid (HSVd, genus Hostuviroid, family Pospiviroidae) has a wide host range among trees and herbaceous plants. The objectives of this study were to compare biological and physical characteristics of three isolates of HSVd from mulberry, fig and citrus and search for other hosts of this viroid in Iran. Materials and Methods: Plant samples were col...

From autumn 2004 to spring 2005, 70 fallow deer (Dama dama), 27 female and 43 male, living in a natural preserve of central Italy were examined by indirect immunofluorescence assay (IFA) to detect specific antibodies to Anaplasma phagocytophilum. Thirty-one (44.28%) sera scored positive: in particular 10 fallow deer (8 male and 2 female) scored positive at 40 antibody titer, 21 deer (8 male and...
