5.1 Ringworm (in Cattle) causing fungi

Trichophyton verrucosum

Ringworm is one of the commonest skin diseases in cattle. Ringworm is a transmissible skin infectious disease caused most often by Trichophyton verrucosum, a spore forming fungi. The spores can remain alive for years in a dry environment. Although unsightly, fungal infections cause little permanent damage or economic loss. Direct contact with infected animals is the most common method of spreading the infection.

The symptoms of Ringworm include Lesions with greywhite areas with an ash like surface usually circular in outline and slightly raised that appears on skin. Size of lesions vary and can become very extensive. In calves the infection is most commonly found around eyes, on ears and on back. In adult cattle infection on chest and legs are more common (Fig. 183)

6.1. Aspergillosis disease causing fungi

Aspergillus fumigatus

Aspergillosis is a fungal infection that commonly causes respiratory disease in pet birds. It can infect both upper (nose, sinuses, eye, and trachea) and lower (lung and air sacs-a specialized part of the respiratory tract that birds have) respiratory organs or more broadly distributed systemic infections (Fig. 187).

The Symptoms includes Weight loss, Open-mouth breathing or gasping for breath, Tracheal movement or in-out-in movements in the region of the neck, Tail-bobbing or movement of the bird’s tail up and down while breathing in and out, heavy breathing after flight or exercise, Change in voice and persistent itching or rubbing of cerenares.

7.1. Black Gill Disease (in Shrimps) causing fungi

Fusarium spp

The affected prawns show brown to black spots on the gills. In acute cases gills may completely become brown or black with atrophy and necrosis (Fig. 192).

7.2. Saprolegniasis disease causing fungi

Saprolegnia

Saprolegniasis is a fungal disease of fish and fish eggs, most commonly caused by the Saprolegnia species called “water molds.” They are common in fresh or brackish water. Saprolegnia can grow at temperatures ranging from 0° to 35°C but seem to prefer temperatures of 15° to 30°C. The disease fungus attack an existing injury on the fish and spread to healthy tissue. Poor water quality (for example, water with low circulation, low dissolved oxygen, or high ammonia) and high organic loads, including the presence of dead eggs, are often associated with Saprolegnia infections.

11.1. Pleurotus ostreatus

11.1 Introduction

Ber (also called Indian Jujube, Indian Plum, Chinese Apple and Masau) is an important minor fruit of India. It is most widely cultivated in Punjab, Haryana, Rajasthan, Uttar Pradesh, Madhya Pradesh, Bihar, Gujarat, Maharashtra etc. Fruits are mostly eaten fresh but other forms, such as dried, candied, squash etc. can be prepared from ber. Stem, bark, root and leaves have some medicinal values. Leaves of ber are used as fodder in dry regions.

12.1 Introduction

Aonla (also called Amla, Indian gooseberry) is a tropical and sub-tropical fruit. It is mainly recognized due to its high nutritive, medicinal and therapeutic properties. It contains high amount of vitamin C (500-1500 mg/100 g); it is also rich in pectin, iron, calcium and phosphorus. Dried fruits of aonla are used in curing haemorrhage, diarrhoea, chronic dysentery, diabetes, jaundice, dyspepsia, cough etc. Aonla is the main ingredient of Chavanprash and Triphala powder. The fruit contains gallic acid and leucoanthocyanin which have antioxidant property. Its cultivation is more common and widely grown in Uttar Pradesh, Gujarat, Rajasthan, Madhya Pradesh and Tamil Nadu.

17.1 Introduction

Almond or badam is a high energy nut. Almond kernels contain lipids (52.2%), protein (20%), carbohydrate (20.4%) and water-soluble sugars (4.4%). Irrigation affects almond yield and quality. Almond quality is primarily genotype dependent. Maturity at harvest can also influence kernel quality.

18.1 Introduction

Among nut crops, ‘Walnut’ or ‘Akhrot’ is the most important crop. It has immense commercial importance even in the areas situated in remotes without having good market and transport infrastructure. Because of long storability, growers have opportunity to hold the produce at room temperature for two to three months easily and sell out at intended time. Walnut is rich in protein, fats and vitamins, especially vitamin B6 . The walnut kernel contains about 90% PUFA of which 26% is the Omega-3 fatty acid, alpha-linolenic acid. But the problem with this type of kernel is that higher the percentage of PUFA in it, the more is the chances of getting the oil oxidized and thereby reducing the shelf life of the walnut kernel.

24.1 Introduction

In India, the commercial cultivation of oil palm started during 1970. Today about 16 countries of tropics cultivate oil palm. The palm oil has been safe and nutritious source of edible oil for human consumption for 1000 years. Palm oil and its liquid fraction palmolein is consumed worldwide as cooking oil. Malaysia, Indonesia, Nigeria and Columbia started to grow oil palm in a large scale during 1980. The commercial producing countries are Liberia, Peru, Angola, Senegal, Ghana, etc.

Doppler ultrasound is a non-invasive diagnostic tool being employed in evaluating blood flow in major vessels, veins and arteries. Information regarding perfusion in an organ or an area can also be obtained through Doppler ultrasonography. Doppler ultrasound is an important part of echocardiographic examination in dogs and cats. Its more recent application is in the investigation of the tissue wall motion while evaluating the heart. B-mode ultrasound is used to examine cardiac structures.

Ultrasound has been used to image thyroid and parathyroid glands. It can assist in the diagnosis of hyperthyroidism and hyperparathyroidism in dogs and cats. Recently it has also been used to differentiate cases of primary hypothyroidism or euthyroid syndrome.

Ophthalmic or ocular ultrasound can provide important diagnostic information that is readily not available with other diagnostic techniques. Ocular ultrasound is emerging as an important diagnostic modality in veterinary ophthalmology.

Sonography of the nervous system in dogs dates back to 1972 when it was employed in experimental studies. Thick bony cage of the brain limits the sonographic evaluation of the brain. It has an important place in human paediatric medicine. Sonography of the brain and the nervous system is not very common in veterinary medicine.

Enterobacteria phage ? is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E.coli). It was discovered by Esther Lederberg in 1950. The wild type of this virus has a temperate life cycle that allows it to either reside within the genome of its host through lysogeny or enter into a lytic phase, during which it kills and lyses the cell to produce offspring. Lambda strains, mutated at specific sites, are unable to lysogenize cells; instead, they grow and enter the lytic cycle after superinfecting an already lysogenized cell.

Soil testing identifies various constraints in soil that limit crop production. Fertilizer recommendation and soil management practices to be adopted are based on the soil test report. Soil testing starts with collection of soil samples from the field
and ends with interpretation of soil test results leading to necessary recommendations for increasing crop production.

Soil texture is the relative proportion of sand, silt and clay in soil by weight. As per the classification of the inorganic soil particle by the International Society of Soil Science, diameters of the sand, silt and clay particles vary from 2 to 0.02 mm, 0.02 to 0.002 mm and less than 0.002 mm, respectively. There are 3 broad textural groups i.e sand, loam and clay and each broad textural group is subdivided into different textural classes depending upon the proportion of sand, silt and clay.

Determination of soil texture mainly depends on the complete dispersion of soil aggregates into their individual primary particles without triturating the particles themselves, accurate fractionation of the sample into various separates, sedimentation of different particles in the viscous medium as well as measurement of individual particle by the hydrometer.

In Bray’s method a mixture of ammonium fluoride and hydrochloric acid (NH4F + HCl) act as the extracting agent. It works in two ways, firstly, the hydrogen ions from HCl have a solubilising effect, especially on Ca-P, which makes phosphate get extracted. Secondly, the fluoride ions (from ammonium fluoride) complex with the Al3+ and Fe3+ ions, thereby releasing the Al and Fe bound phosphorous into the extract.

Soil is shaken with 0.15 % CaCl2 solution. Chloride ions displace adsorbed sulphate during extraction. Calcium ions suppress the extraction of soil organic matter and hence eliminate the contamination caused by extractable organic S.

Diethylene tetramine penta acetic acid (DTPA) being a chelating agent is used in the determination of available Fe, Mn, Cu and Zn. When the soil is shaken with a solution of DTPA, it combines with metal ions in the solution and form soluble complexes of Fe++, Mn++, Cu++ and Zn++. The CaCl2 and triethanolamine (TEA) solution slightly raise and buffer the soil pH and mitigates the effect of Ca++ and Mg++.
