myxosporeans are best known for the diseases they cause in commercially important fish species. identification of myxosporeans at the species-level is mainly based on conventional methods. the 18s rrna gene sequence of morphologically identified myxobolus orissae infecting the gill lamellae of mrigal carp cirrhinus mrigala was characterized in the present study. the plasmodia of m. orissae were...

acanthamoeba keratitis is a vision-threatening infection caused by pathogenic species of the genus acanthamoeba. in this study, 13 acanthamoeba keratitis cases were diagnosed among 52 keratitis patients. to confirm the identity of acanthamoeba at the genus level, a pcr-based method was used, and their pathogenic potential was determined using in vitro cytotoxicity assays on human corneal epithe...

UNLABELLED Poxviruses are large DNA viruses of vertebrates and insects causing disease in many animal species, including reptiles, birds, and mammals. Although poxvirus-like particles were detected in diseased farmed koi carp, ayu, and Atlantic salmon, their genetic relationships to poxviruses were not established. Here, we provide the first genome sequence of a fish poxvirus, which was isolate...

It must be clearly understood that the disease, as it occurs in jails, is in no way different from that occurring in the free population ; the only difference is one of severity, being more virulent in certain jails, and this I put down to the large number of men confined in a certain space, not necessarily overcrowded, to the depressing effect of jail life, and in certain cases to bad sanitati...

Entamoeba histolytica is an enteric protozoan that exclusively infects human beings. This parasite requires iron for its metabolic functions. Lactoferrin is a mammalian glycoprotein that chelates extracellular iron on mucosal surfaces, including the surface of the large intestine, where E. histolytica initiates infection. This work examined the interaction in vitro of E. histolytica trophozoite...

introduction: determination of the efficacy of crude entamoeba histolytica extract and its fractions (fi,fii & fiii) in antiamoebic antibody detection by elisa. material and methods: entamoeba histolytica nih:200 was cultured axenically and different fractionsof its crude amoebic extract, i.e. fi, fii & fiii, were obtained by column chromatography. efficacy of crudeand fractioned antigens for a...

During a survey on Myxobolus infection of pond-cultured common carp in Syria three Myxobolus spp. were found. Myxobolus dispar infected the gill arteries, forming large elongated plasmodia in the gill filaments. The plasmodia of M basilamellaris were located in the gill arches at the base of the filaments. Elongated filiform plasmodia of M. encephalicus were found in the blood vessels of the br...

Fulminant necrotising amoebic colitis is a complication of untreated amoebiasis. This is seen in mainly low-income countries. It has a high mortality rate and is difficult to diagnose. We present an extremely rare case of fulminant necrotising amoebic colitis that caused diagnostic confusion in mimicking an acute abdomen, presumably caused by a perforated duodenal ulcer.
