| molecular and biological characterization of first isolates of hammondia hammondi from cats from ethiopia. | toxoplasma gondii oocysts are morphologically and antigenically similar to oocysts of another feline coccidian, hammondia hammondi. the distinction between h. hammondi and t. gondii is important from an epidemiological perspective because all isolates of t. gondii are potentially pathogenic for humans and animals, whereas h. hammondi is not known to cause clinical disease in any naturally infected intermediate or definitive hosts. in the present report, h. hammondi (designated hhcatet1 and hhcat ... | 2013 | 23517380 |
| high prevalence of anti-toxoplasma antibodies and absence of toxoplasma gondii infection risk factors among pregnant women attending routine antenatal care in two hospitals of addis ababa, ethiopia. | toxoplasmosis is an infection caused by the protozoan parasite toxoplasma gondii. it is acquired mainly by eating raw or undercooked meat containing toxoplasma gondii tissue cyst, eating food or water contaminated with oocyst, and acquiring congenital infection through the placenta. this study was conducted to determine the prevalence of toxoplasmosis and assess possible risk factors associated with the infection among pregnant women in addis ababa, ethiopia. | 2015 | 25759324 |
| prevalence of toxoplasma gondii from free-range chickens (gallus domesticus) from addis ababa, ethiopia. | prevalence of toxoplasma gondii in free-range chickens (gallus domesticus) is a good indicator of the environmental contamination with oocysts because chickens become infected mainly by feeding from ground, feed, or soil contaminated with oocysts. the seroprevalence of t. gondii antibodies in 125 free-range chickens from the addis ababa, ethiopia, was determined. antibodies to t. gondii were assayed by the modified agglutination test; 48 of 125 (38.4%) chickens were seropositive, with titers of ... | 2013 | 23259902 |
| isolation of viable toxoplasma gondii from tissues and feces of cats from addis ababa, ethiopia. | cats are important in the epidemiology of toxoplasma gondii because they are the only hosts that excrete environmentally resistant oocysts in feces. in the present study, hearts, serum, and feces from 36 feral cats from addis ababa area, ethiopia, were examined for t. gondii infection. antibodies to t. gondii were determined with the modified agglutination test (mat, cutoff 1:25); 33 cats were seropositive. hearts of all 36 cats were homogenized, digested in pepsin, and bioassayed in mice. feces ... | 2013 | 22924928 |
| an investigation into the seroprevalence of toxoplasma gondii, bartonella spp., feline immunodeficiency virus (fiv), and feline leukaemia virus (felv) in cats in addis ababa, ethiopia. | toxoplasma gondii and bartonella spp. are zoonotic pathogens of cats. feline immunodeficiency virus (fiv), and feline leukaemia virus (felv) are immunosuppressive viruses of cats that can affect t. gondii oocyst shedding. in this study, the prevalence of antibodies to t. gondii, bartonella spp., fiv, as well as felv antigens were determined in sera from feral cats (felis catus) from addis ababa, ethiopia. using the modified agglutination test, igg antibodies to t. gondii were found in 41 (85.4%) ... | 2013 | 22857007 |
