A new species of parasitic nematode, Cystoopsis atractostei (Trichinelloidea: Cystoopsidae), is described based on female specimens recovered from the subcutaneous tissue of the tropical gar, Atractosteus tropicus Gill (Lepisosteiformes: Lepisosteidae), from 2 localities (Canal Nueva Esperanza and Canal Tabasquillo) of the Pantanos de Centla Biological Reserve, State of Tabasco, southeastern Me...

A 72 year old Thai male; a resident of Kapoe district, Ranong Province, Southern Thailand presented with conjunctivitis of the left eye. A filariid nematode was recovered from under the medial side of ocular conjunctiva of the left eye. The filariid nematode was identified as a young adult female Parafilaria bovicola, based on the following characteristics: no alteration of the transverse stria...

Capoeta buhsei is native species in the Namak Lake basin and biological aspects of life history of this fish in Iranian waters is not very well known. Life history of this fish examined by collecting 92 samples in Gharachay River. Sampling done by using Electroshoker in July and January 2011 and October 2012. The maximum age was found +4 years in female. Sex Ratio (male: female) was 1:0.73, and...

the purpose of this research was to determine the effect of two kinds of diet (zinc deficiency and iron deficiency) on some anthropometrical indexes (body weight and crown-rump length), brain growth and motor function in young rats. adult male and female albino wistar rats were obtained from the breeding colony of pasteur institute, iran. the female albino rats were mated with normal male rats....

introduction: root-knot nematodes (meloidogyne spp.) are important plant pathogens that make large damage to the crops. the activity of root-knot nematode and reaction of host plant results in the development of several knots on the root, which interrupts water and food absorption system of the plant. among popular methods for controlling root-knot nematodes are physical methods (soil solarizat...

We previously reported significant body size change in the nematode Caenorhabditis elegans, depending on the food strain of E. coli. Here, we examined this body size change in 11 other nematode species as well, and found that it is common to most of these nematodes. Furthermore, this food-dependent body size change is influenced by sex and growth temperature.

In this study, nematodes were first reported in the amphipods, Ischyrocerus commensalis, collected from introduced and commercially important red king crabs, Paralithodes camtschaticus, coastal Barents Sea July 2022. Commensal amphipods registered on all crabs captured (n = 70, prevalence 100%). Further laboratory analysis revealed that 11 out of 467 amphipod individuals (prevalence 2.4%) harbo...

abstract background: critical care patients are at higher risk for untreated pain. pain has persistent and untreated effects on most of the body systems and results in development of complications, chronic pain, and increased length of stay. the aim of this study was to determine the effects of the implementation of a pain management program on the length of stay in patients with decreased leve...
