Abstract Background & Aims: Toxocariasis or visceral larva migrans syndrome is a disease that appears by attack of extra intestinal animal nematode larvae of Toxocara canis to the human tissues. The present study was performed to evaluate the frequency of Toxocara eggs in public parks of Shiraz /Iran. Methods: A total of 20 parks from different regions of shiraz city were selected, and from dif...

ABSTRACT Nematode control strategies are limited and alternative is demanded. The main aim was to evaluate potential of Hohenbuehelia spp. (Hohenbuehelia mastrucata, barbatula, bullulifera, portegna, petaloides paraguayensis) Trichoderma koningiopsis against Meloidogyne javanica in bean plants greenhouse. parameters evaluated were the number galls egg masses which three root regions: basal, int...

Globodera infestation was evaluated in soils of private farm plots Chernihiv and Kyiv regions Ukraine 2017–2018. Soil samples were taken at 88 farms, 15.02 ha total, 11 settlements 6 districts. The nematode abundance the examined areas graded as follows: less than 1000 eggs + larvae/100 cm3 — low rate infestation; 1000–5000 average rate; more 5000 high rate. 85.4 % study area is infested with g...

The purpose of this study was to evaluate the efficiency Pseudomonas aeruginosa strain Dokkala (OK383444) isolate against cyst nematode Globodera pallida (MZ959187) as a biocontrol agent on potato nematode. test first conducted in vitro with bacterial suspensions at 105, 106, 107 and 108 CFU/mL 100 eggs, second-stage juveniles (J2), 10 cysts G. then vivo variety Desiree infested by greenhouse. ...

Faecal specimens collected in the Kruger National Park from 103 African buffaloes (Syncerus caffer) up to 1 year old and 283 buffaloes older than 1 year were examined for the presence of coccidian oocysts and nematode eggs. Most specimens from animals older than 1 year had negative coccidian oocyst counts. Positive specimens from younger animals had significantly higher coccidian oocyst counts ...

Fergusobia nematodes and Fergusonina flies are mutualists that cause a variety of gall types on myrtaceous plant buds and young leaves. The biology of an isolate of the gall complex was studied in its native range in Australia for possible use in southern Florida as a biological control agent against the invasive broad-leaved paperbark tree, Melaleuca quinquenervia. Timed studies with caged Fer...

Population fluctuations of Heterodera glycines differ in fields with high and low initial population densities. In a field with low initial numbers of nematodes, the numbers of cysts and eggs in soil remained low through 100 days from planting then increased during the remainder of the growing season. In a field with high initial nematode populations, numbers increased at 30 days, decreased to ...

It is known from studies in a wide range of wild and domestic animals, including elephants, that parasites can affect growth, reproduction and health. A total of 458 faecal samples from wild elephants were analysed using a combination of flotation and sedimentation methods. Coccidian oocysts (prevalence 51%), and nematode (77%) and trematode (24%) eggs were found. Species were not identified, t...

A degree-day model was derived to predict egg hatch for Criconemella xenoplax. Eggs collected from gravid females were incubated in distilled water at constant temperatures of 10-35 C. Sixty-six percent of all eggs hatched between 13 and 32 C, and 42% hatched at 10 C. All eggs aborted above 32.5 C. Between 25 and 32 C, 8.5 +/- 0.5 days were required for egg hatch. Degree-day requirement for egg...

Cultures of P. chlamydosporia from infected nematode eggs in soil from different parts of the world have been freeze-dried and retained at Rothamsted Research, prior to use. Eight isolates (five collected from cyst nematode eggs and three from root-knot nematode eggs) were grown on 1.7% corn meal agar (Oxoid, Basingstoke, UK) at 25C prior to use. Chlamydospores used as inoculum were produced in...
