Host List

Published and personal records have been compiled into a reference list of the helminth parasites of guineafowls. Where data on other avian hosts was available these have been included for completeness' sake and to give an indication of host range. The parasite list for the Helmeted guineafowls, Numida meleagris, includes five species of acanthocephalans, all belonging to a single genus, three trematodes belonging to three different genera, 34 cestodes representing 15 genera, and 35 nematodes belonging to 17 genera. The list for the Crested guineafowls, Guttera edouardi, contains a single acanthocephalan together with 10 cestode species belonging to seven genera, and three nematode species belonging to three different genera. Records for two cestode species from genera and two nematode species belonging to a single genus have been found for the guineafowl genus Acryllium. Of the 70 helminths listed for N. meleagris, 29 have been recorded from domestic chickens.

The mammalian gut is a remarkable organ: with a nervous system that rivals the spinal cord, it is the body’s largest repository of immune and endocrine cells and houses an immense and complex microbiota. Infection with helminth parasites elicits a conserved program of effector and regulatory immune responses to eradicate the worm, limit tissue damage, and return the gut to homeostasis. Discrete changes in the nervous system, and to a lesser extent the enteroendocrine system, occur following helminth infection but the importance of these adaptations in expelling the worm is poorly understood. Approximately 90% of the body’s serotonin (5-hydroxytryptamine (5-HT)) is made in enterochromaffin (EC) cells in the gut, indicative of the importance of this amine in intestinal function. Signaling via a plethora of receptor subtypes, substantial evidence illustrates that 5-HT affects immunity. A small number of studies document changes in 5-HT levels following infection with helminth parasites, but these have not been complemented by an understanding of the role of 5-HT in the host–parasite interaction. In reviewing this area, the gap in knowledge of how changes in the enteric serotonergic system affects the outcome of infection with intestinal helminths is apparent. We present this as a call-to-action by investigators in the field. We contend that neuronal EC cell–immune interactions in the gut are essential in maintaining homeostasis and, when perturbed, contribute to pathophysiology. The full affect of infection with helminth parasites needs to define, and then mechanistically dissect the role of the enteric nervous and enteroendocrine systems of the gut.

An epidemiological study of the nematode parasites of the eastern grey kangaroo (M. giganteus) was made in an enclosed reserve north of Melbourne, Victoria, Australia. Adult and juvenile kangaroos were collected at approximately 6-weekly intervals and blood, faeces and the entire gastrointestinal tract was obtained. The nematodes present were Globocephaloides trifidospicularis, Rugopharynx australis, R. rosemariae, Pharyngostrongylus kappa, Cloacina spp., Strongyloides sp., Macropostrongylus baylisi, Paramacropostrongylus toraliformis, Alocostoma clelandi, Labiostrongylus spp., Macroponema comani and Macropoxyuris. The majority of nematodes had a seasonal fluctuation. Acquisition commenced in late summer and reached a peak in midwinter before declining in spring. G. trifidospicularis caused considerable mortality in juvenile kangaroos and there was a strong relationship between rising numbers of this species and falling plasma protein, haemoglobin concentration and haematocrit values. This species can cause heavy mortality in juvenile kangaroos in enclosed populations when winter feed is depleted and when the small animals with no fat reserves experience maximum cold stress. Other parasites present included Progamotaenia ewersi, P. festiva, P. macropodis, Triplotaenia fimbriata, T. undosa, Eimeria wilcanniensis, E. macropodis, E. hestermani and E. marsupialum.

An attempt was made in the present investigation to study the behaviour problems among children. Sample for the present study consists of thirty (30) parents, both fathers and mothers and their children with problem behavior in Chittoor of Andhra Pradesh State.Achenbach Child Behavior Check List (1991) was designed to empirically assess the behavior problems of children ranging 6-18 ages and 't' tests were used to analyse the data. Findings of the study revealed that gender and locality have significant differences in behaviour problems among children.

All the common species that were easily obtained in this locality, have had names in my collection for many years, but owing to the changes that were being made in the genera and synonymy of species, I was not in a position to follow them up, so that when Mr. Grote's “New Check List” appeared, which I have followed in this, I found that several of my old names had disappeared altogether, and others had been rendered doubtful.
