Protein chromatographic study on adult ascaris lumbricoides, ascaris vitulorum and toxocara canis

Chromatographic analysis using Sephacryl S.300 was done on protein extract of adult Ascaris lumbricoides, A. vitulorum and Toxocara canis worms. Six fractions were separated from both Ascaris species and nine from T. canis. Fractions revealed a variety of molecular weights in relation to the three species of worms that ranged from 6,000 - 70,000 daltons. Crude extract of T. canis showed cross reaction with both species of Ascaris sera using double gel diffusion, while no reaction was obtained using a partially purified antigen

Acanthamoeba keratitis

Fifty-five patients of active keratitis, contact lens wearers, corneal opacities prepared for keratoplasty, and 20 controls were involved in this study. All cases were subjected to ophthalmological and laboratory investigations. In some cases of corneal biopsy histopathological investigations were applied. This was aimed for detection of acanthamoeba as a causative pathogen for keratitis among the Egyptian patients. Results demonstrated no evidence of acanthamoeba in the examined samples except infiltration with inflammatory cells on histopathological examination of the corneal tissues of 5 cases

Concomitant toxoplasma and toxocara infections

Toxoplasmosis being to a large extent a soil transmitted infection is acquired in the same manner and often at the same time as toxocariasis, the source being concomitantly infected cats. 110 sera of patients suspected of toxoplasmosis and found positive by the indirect fluorescent antibody test [IFAT], were also tested for Toxocara antibodies by the IFAT. Seropositivity was found to be 18.1%. On the other hand, 12 sera from patients presenting with toxocariasis and proved serologically positive, were tested to detect Toxoplasma antibodies and only one was positive [8.3%]. Association of antibodies of the two parasites was found in 21 sera [17.2%]

Toxoplasmosis as a cause of ocular and nervous mainfestations

This study was done on 287 cases with different age and sex from ophthalmic and neurologic clinics. The indirect fluorescent antibody test [IFAT] was performed on all cases and gave 19.5% positivity for those who gave positive reaction, the IFAT-IGM as well as the immuno-electrophoresis [CIEP] tests were done. The IFAT-IGM was positive in two cases

survey of some ophthalmic problems in hurghada

An organised survey of the inhabitants off Hurghada attending the outpatient clinic and of school children was carried out. Among the 300 outpatient clinic visitors, pterygium was searched for in adults and refractive errors in children below 15 years of age. Pterygium was found ion 5% of patients [15/300]. Of the 720 school children examined, a search for the different stages of trachoma and refractive errors was stressed upon. Two hundred and ninety two [292] children [40.56%] were affected with different stages off trachoma, while 112 [15.6%] had refractive errors. One hundred and thirty [130] persons were randomly selected to test for the incidence of toxoplasmosis, of them 15 persons [11.54%] gave positive results

Involvement of the eyes infection with trichinella spiralis

Eyes were collected from swines. The extraocular muscles in each eye were examined for the presence of larvae. Examination of diaphragm muscles of the corresponding swiness was done. Larvae were seen in most of the extraocular muscies. Indirect fluorescent antibody test [IFAT] was performed on the aqueous humor collected from eyes to determine the presence of antibodies for trichinella
