background and objectives : 300 pseudomonas aeruginosa strains were isolated from hospitalized patients in iran. using international antigenic typing system (iats) antibodies, all strains were classified into 16 serotypes while serotype 14 was not identified among the 17 known serotypes. to evaluate the rate of cross-reactivity between o- antigenic determinants, monospecific polyclonal antibodi...

Flourescent antibody test (FAT) was applied to determine the cross-reactivities of monoclonal (mAb), polyclonal (pAb) antibodies to Neospora, Toxoplasma and Cryptosporidium and antisera from cattle naturally infected with Neospora canium against antigens from a number of sources. Both mAb and pAb to Neospora reacted strongly (FAT titre up to 2560) with the homologous antigens and demonstrated w...

background: mediterranean visceral leishmaniasis (mvl) is an infectious disease that affects both human and ani­mals. domestic dogs ( canis familiaris ) are principal reservoir hosts of mvl caused by leishmania infantum . dogs are definitive hosts for neospora caninum and a risk factor for infecting intermediate hosts. the immunosuppression caused by visceral leishmaniasis (vl) can promote the ...

The purpose of the present work was to identify Neospora caninum infections in beef bulls belonging to 19 herds from six counties located in the Corrientes province, Argentina. The presence of antibodies to N. caninum was evaluated in 305 serum samples of bulls (Bos taurus and Bos indicus). Age and breed were recorded. An indirect fluorescent antibody test was used to determine specific antibod...

background: visceral leishmaniasis (vl) or kala-azar is a parasitic disease caused by the species of leishmania donovani complex. mediterranean type of the disease is endemic in some parts of iran and more than 95% of cases were reported in children up to 12 years of age. this study was performed to determine the seroprevalence of vl in the rural areas of dashti district from bushehr province. ...

background: this study aimed to determine the seroprevalence of canine visceral leishmaniasis in meshkin-shahr district as endemic areas of human visceral leishmaniasis (hvl) for presenting control program of hvl to health authorities.  methods: a seroepidemiological study to determine seroprevalence of canine visceral leishmaniasis (cvl) among owner­ship dogs using direct agglutination tests (...

b a c k g r o u n d & aim: visceral leishmaniasis (vl) or kala-azar is a parasitic disease caused by the species of leishmania donovani complex. mediterranean type of disease is endemic in some parts of iran and more than 95% of seropositivity cases were reported in children up to 12 years of age. a cross-sectional study was conducted to determine the seroprevalence of vl in nomadic tribe’s pop...

OBJECTIVE The University Hospital in Hamburg (UKE) started to develop a test of knowledge in natural sciences for admission to medical school in 2005 (Hamburger Auswahlverfahren für Medizinische Studiengänge, Naturwissenschaftsteil, HAM-Nat). This study is a step towards establishing the HAM-Nat. We are investigating parallel forms reliability, the effect of a crash course in chemistry on test ...

We describe the search toward a fast and reliable strategy to detect and confirm the presence of methicillin-resistant Staphylococcus aureus (MRSA) in screening samples. First, we evaluated the sensitivities and specificities of oxacillin resistance screening agar (ORSA) with enrichment (tryptic soy broth [TSB] and ORSA [TSB-ORSA]) and without enrichment (ORSA), MRSA ID (MRSA_ID) plates, and CH...

background : neospora caninum is an intracellular parasite which causes abortion in cattle worldwide.  the aim of this study was to determine the seroprevalence of n. caninum in cattle in babol city, north of iran. methods: blood samples were collected from 237 cattle for determining the seroprevalence of n.  caninum .  a total of 237 serum samples were tested for anti- neospora antibodies.  se...
