Abstract:

SUMMARYThe relationship between faecal examination for egg output and worm burden of Opisthorchis viverrini in man of 181 autopsy cases from Northeast Thailand is described. Diagnosis of the parasite infection by stool examination for the presence of eggs was less sensitive than the worm recovery technique. Using Stoll's dilution and formalin–ether technique, no eggs were detected in the faeces of 20 cases harbouring low worm burdens (< 20 worms). The quantitative faecal egg count by Stoll's dilution technique showed a strikingly close positive correlation with the number of worms recovered

Abstract:

Egg cases from nine skate species occurring in Tasmanian waters were examined and measured. A species-specific identification key is provided for eight of these species. The key was developed primarily from fresh egg cases dissected from the oviduct, although specimens collected from the ocean floor or found dried on the beach were also used to test the key. Egg cases for the ninth species could not be included because the only egg case pair recovered was partially formed. A diagnosis of the posterior end of this egg case is provided.

Abstract:

House Wrens (Troglodytes aedon Vieillot, 1809) regularly add spider egg cases (Arachnida: Araneae) to their nests, which may be an example of heterospecific cleaning. This behavior involves one animal employing another to remove parasites from their nests. In House Wren nests, juvenile spiders hatching from egg cases may facilitate the reduction of mites that feed on nestlings. We tested this ectoparasite reduction hypothesis by monitoring House Wren nests for spider egg cases and by collecting completed nests to compare the number of spider egg cases and Dermanyssus hirundinis (Hermann, 1804)

Abstract:

Eleven egg cases of Beringius marshalli (Dall, 1919) (Gastropoda: Buccinidae: Beringiinae) were found in the northern part of the Okhotsk Sea. Egg cases consist of 2-7 rounded capsules. Largest capsule has 54 mm in height and 31 mm in thickness. Capsule contains 2-3 embryos and numerous nurse eggs. Some egg capsules contained 2-3 young specimens (height 15.8, diameter 7.1 mm), which have well-developed cal- careous shells.

Abstract:

Egg cases for 10 of 11 valid skate species known to occur in the eastern North Pacific (ENP) were identified and are here described. In addition, egg cases of two unidentified skate species were collected from very deep water off central and southern California, USA. Examples of egg cases for all species, except for two, were removed in utero in order to confirm their species specific identification. The egg cases of seven skate species, including egg cases from the two unidentified species, have not previously been described or illustrated from this region. Previous attempts to identify skate

Abstract:

A survey of the cholesterol levels of eggs from White Leghorn hens from across Canada was performed. High-performance liquid chromatography was used for cholesterol analysis. The cholesterol concentrations were found to range from 12 to 15 mg g−1 yolk, and the mean value for all eggs was 13.0 mg g−1 or 221 mg egg−1. Large eggs (35 out of 56) contained an average of 214 mg cholesterol egg−1. The effect of farm on cholesterol concentration (mg g−1 yolk) was significant (P < 0.05) and in most cases sample variation (P < 0.05) was found within each farm. Cholesterol content (mg egg−1) correl

Abstract:

Two experiments were conducted to study the effect of canola-meal-supplemented laying diets on egg size. In diets where canola protein made up half or all of the supplemental protein, egg size was significantly reduced as compared to a corn-soybean control diet. With the canola meal diets, on a percentage basis, feed intake was reduced by a percentage similar to that of egg weight. Reduced egg size was also observed when laying hens were fed corn-soybean meal diets containing 10% canola meal with various dietary supplements. In most cases where smaller egg size was noted, the energy intake of

Abstract:

The pattern of intraclutch egg-size variation in barnacle goose (Branta leucopsis) clutches and its adaptive implications was studied in Svalbard, Norway, from 1989 to 1998. Egg size was measured in relation to laying sequence, egg predation and hatching order were recorded to determine hatching success of eggs in different laying sequences, and the time when incubation started was examined. Egg size showed a rather consistent pattern, with a large second-laid egg and declining egg size for the remainder of the clutch. The first-laid egg was usually smaller than the second one, except in clutc

Abstract:

Belonging to the diverse order Araneae, the black widow spider Latrodectus 4 hesperus produces high-performance silks with a broad range ofbiological functions and mechanical properties. The cob weaver spider spins different fibers by using seven specialized glands located in its abdomen. Egg case silk originates from the tubuliforrn gland and to date, no proteins that participate in the assembly process of egg case silk proteins have been identified. The goal of this project was the expression, purification, and characterization of such protein products. De novo sequencing of peptides from in
