Understanding Your Kidneys and CKD
It also removes bitterness, makes the vegetables more digestible, more colourful, and sweeter. Veterinarians use ambiguous terms to describe what is happening in your cat's liver and gall bladder. Studies in Modern Jewish Literature. Once your cat has been stabilized and sent back home, it will most likely need a special diet and occasional medications throughout its life. Fish Disease Leaflet Endothermy, though metabolically costly, is thought to provide advantages such as increased muscle strength, higher rates of central nervous system processing, and higher rates of digestion. Pancreatitis can occur only once, or it can reoccur again and again.
The SFPUC claims that chloramine is more effective than chlorine in getting rid of pathogens and lowering possible carcinogens in the water, i. There are other alternatives. Chloramine is an attractive choice because it is easy to make and one of the least expensive disinfectants in a list of 15 EPA options. However, chloramine is a much less effective disinfectant than chlorine.
And unlike chlorine, chloramine itself has not been studied for its human health effects. In industry, it is well known that chloramine is a skin and respiratory irritant. Yet, according to the EPA, NO dermal or inhalant studies on the effects of chloramine as used as a water disinfectant have ever been conducted. Despite the lack of studies, many major water utilities in California and across the country are now using chloramine.
Most have switched only recently. The introduction of chloramine resulted in a number of adverse health reactions to individuals. These reactions revealed the toxicity of the new additive in the water being piped to Bay area households. Many of the individuals affected had no idea that anything new was being introduced into the water. Many people still do not know of the change.
A tiny statement attached to the bottom of a homeowner's water bill was easily missed. Apartment dwellers in a number of cities received no notice at all because they do not pay a separate water bill.
Rash which developed after introduction of chloramine in February Same legs after avoiding tap water beginning September Suddenly, a number of people reported experiencing intense burning and itching of their skin during and after washing or bathing in the newly chloraminated water. Many also developed severe dry skin, rashes, welts and blisters.
When these individuals stopped using their chloraminated tap water and substituted non-chloraminated water sources such as bottled spring water, their symptoms went away. Other people developed respiratory symptoms from exposure to the chloraminated water especially after showering and bathing.
These symptoms ranged from severe sinus congestion, sneezing, coughing, choking and wheezing to severe asthma, breathing difficulties and loss of consciousness from asphyxiation.
The worst respiratory symptoms occurred during or after bathing or showering in chloraminated water. Again when these individuals stopped using the chloraminated water their symptoms cleared up. There were also people who began experiencing severe dry eye, mouth, and throat, excessive peeling and chapping of the lips, and digestive problems.
All these symptoms were alleviated when the chloraminated water was avoided. In addition, there were reports of fish and other aquatic species dying after water mains broke, spilling chloraminated water into streams and other waterways including creeks in areas served by the East Bay Municipal Utilities District, Marin Municipal Water District, and the Lower Mainland of British Columbia in Canada-- see the Assessment Report - Inorganic Chloramine.
Also, there were reports of expensive plumbing damage due to the corrosive effects of chloramine. On June 30, , Denise Johnson-Kula who was severely affected by the chloramine, was joined by eleven other individuals who had also experienced the adverse reactions.
They decided to take action to help those suffering the symptoms. Today, CCAC has hundreds of members and has become an active and strong advocate for the removal of chloramine from the water supply to eliminate the harmful effects of chloramine. Unlike copepods—another group of crustacean fish parasites, such as Lernaea the Anchorworm branchiurans continue to molt periodically even after reaching maturity.
Some chemical control methods see Diagnosis and Management kill the parasite by inhibiting the molting process. While the branchiuran life cycle averages 30 to 60 days, the actual duration depends on the parasite species and the water temperature. All life stages of both sexes are parasitic—unlike the non- parasitic male Anchorworm Lernaea , Argulus adults can survive for several days off the fish host.
After she releases her eggs, the female returns to the fish host. The time required for Argulus eggs to hatch will vary, depending upon the species and temperature. If laid in the fall, eggs are capable of over wintering surviving until the following spring. Disease in Fish Caused by Argulus: Argulus infestations tend to peak in the summer and fall. The lice can be found attached to the skin, gill chamber, and mouth.
Localized inflammation occurs at the contact site because of mechanical damage from hooks and spines on the stylet and appendages, and irritation from digestive enzymes.
In heavy infestations, the fish lice may be seen all over the skin and fins of the fish and in the water column Figures 3 and 4. Fish without visible lice may show non- specific signs of infestation.
These include spot or pinpoint hemorrhages, anemia, fin and scale loss, increased mucus production, lethargy, erratic swimming, reduced feeding, hanging at the surface avoiding swimming into the water column and poor body condition. In some cases, there may be no obvious signs of disease other than presence of the parasite.
Individual adult and late stage juvenile Argulus are easily seen with the unaided eye. Note readily visible oval parasites in throat ventral area of head, as well as others scattered throughout the body.
Although fish may tolerate low and even moderate levels of Argulus with very few signs of disease, localized inflammation and damage at the affected site may lead to secondary infections. Secondary pathogens, such as the bacteria Aeromonas and the water mold Saprolegnia , are often seen concurrently with Argulus infestations. Argulus is also capable of acting as a mechanical vector or intermediate host for several fish diseases. The parasite can carry and transmit spring viremia of carp, a reportable viral disease of Koi, common carp, and goldfish, among other hosts.
Aeromonas salmonicida , an important bacterial pathogen, has been isolated from Argulus coregoni, and experiments demonstrated higher rates of Aeromonas infection when Argulus are present, but direct transmission from louse to fish has not yet been proven.
Argulus can also serve as the intermediate host for several species of nematodes roundworms. Because of their size, older stages of Argulus can be diagnosed with the naked eye.
The parasites are visible moving on the host or swimming in the water. The parasite can also be identified on a wet mount of the affected tissue. Captured fish should be examined quickly because Argulus may rapidly leave the fish once it is disturbed or removed from the water.
Filtering water from the system through a fine mesh net may also help capture free- swimming Argulus adults or juveniles for identification. Adults and juvenile stages which are similar to adults but lack suckers are relatively easy to identify, but their identification should be verified by a fish health professional.
Drug choice and length of treatment for Argulus infections should take into consideration the life cycle of the parasite, which varies from 30 to 60 days depending on temperature and species. Treatment should target all life stages, including eggs, juveniles, and adults, both on the fish and in the environment. Adult parasites can be manually removed from the affected fish, but this is impractical in many situations and is an incomplete solution because eggs, unattached juveniles, and adults will still be present in the environment.
Fish can be moved to a clean tank and treated with the appropriate drugs, while eggs in the original system are eliminated either by cleaning and disinfecting the tank or allowing it to dry completely. However, drying may be difficult in humid areas, and at cooler temperatures eggs can survive much longer time periods.
Optimal water quality should be maintained for the duration of any treatments. It is best to work with a fish health specialist. There are currently no FDA- approved drugs for the treatment and control of Argulus. Diflubenzuron effectively kills both adult and larval stages, but it is a restricted- use pesticide, and applicators must follow label instructions.
