Tetrachlorvinphos was added to the mineral mixture of medicated cattle (n = 13) at the rate of 1.6 mg/day/kg of body weight for a 29-week period beginning May 2, 1975. Data suggest that the level ...

1 The influence of particle size on absorption of digoxin was studied in ten healthy volunteers who received 0.5 mg digoxin as two standard Lanoxin tablets, or tablets containing micronized digoxin or large particle size digoxin. Tablets were given 30 min after 15 mg propantheline, 10 mg metoclopramine or a ...

Medication of broilers with arprinocid [MK-302, 9-(2-chloro-6-fluorbenzyl adenine)] had 3 distinct effects on oocysts; (1) the number of oocysts produced was decreased, (2) fewer of the oocysts sporulated, and (3) those oocysts which did sporulate were less infective than those from unmedicated birds. The drug level necessary to prevent passage ...

A study was made of the effect of monensin on the development of immunity to E. maxima, E. brunetti or E. tenella in chickens given repeated inoculations of oocysts. Birds were inoculated three times weekly with either 1000, 100 or 10 oocysts for a total of 13 inoculations. Faecal oocyst ...

Using lamellar keratectomy as a model, the effect of 5-iodo-2' deoxyuridine (IDU) and dexamethasone on epithelial regeneration and stromal wound healing in rabbits was studied. Under IDU medication, there was a dose-dependent delay in both epithelial and stromal regeneration of the cornea. This negative effect of IDU was considerably intensified ...

Sixteen female and 16 male lambs were used in 4 groups to determine the effect of monensin on naturally occurring and experimentally induced coccidiosis. Determinations of numbers of oocysts discharged, quantities of feces discharged, feed consumption, and weight gain were made for female and male lambs in each group. The ...

Furazolidone and carbadox, as feed additives, were only partially effective for the treatment of experimentally induced infections of Salmonella choleraesuis var kunzendorf in swine. There was little difference in mortality between the medicated exposed and the nonmedicated exposed swine, and medication did not markedly decrease rectal temperature. In experiment I, ...

The addition of the aminoglycosidic antibiotic, G-418, to drinking water at the concentration of 37.5 mg/L for 3 days was effective in treatment of experimentally induced swine dysentery in swine. With this concentration, there was a recession of diarrhea during or immediately after withdrawal of medication. However, the diarrhea recurred ...

The addition of ipronidazole to drinking water at concentrations of 50 and 100 mg/L was effective for treatment of experimentally induced swine dysentery in swine because diarrhea receded in most swine within several days after the drug was added. Medicated swine given these concentrations of drug had fewer days of ...

To evaluate efficacy of Tiamuline in mycoplasmosis of chickens and turkeys under controlled field conditions 2 prophylactical and 3 therapeutical trials were conducted. The compound was administered via drinking water for 3 days in comparison to Tylosin tartrate. In both prophylactical and therapeutical tests, Tiamuline showed a superior efficiacy, as ...

Infections with single species of Eimeria acervulina, E. mivati, E. maxima, E. tenella, E. necatrix, and E. brunetti, and the six species mixed, were utilized in three separate battery experiments to evaluate the anticoccidial efficacy of various levels of salinomycin (AHR-3096), a fermentation product of a strain of Streptomyces albus. ...

A field outbreak of suspected poisoning is recorded from feed medicated with the organophosphorus insecticide trichlorfon. A controlled experiment showed that toxicity could occur when trichlorfon was fed from 3-5 days at levels greater than that recommended. Signs recorded were inappetence, muscle tremor, ataxia and deaths. Attention is drawn to ...

Levels of 20, 30, 40, 60 and 120 parts per million (p.p.m.) of ronidazole in water were evaluated for therapeutic efficacy against histomoniasis. Three experiments were conducted with Broad Breasted Bronze and/or Large White poults four to nine weeks old. All poults except the unexposed controls were each given approximately ...

Seventeen cases of neonatal intestinal obstruction due to inspissated milk curds were seen at this hospital in the 9 years 1964-1972. The obstruction started on the 2nd to 10th day of life. Half the babies passed blood from the rectum and in most the x-rays were diagnostic. All survived, 14 ...

Nasal secretions, leukocytes and preputial or vaginal swabs from a group of 15 captive wild ruminants, comprising six pronghorn antelope (Antilocapra americana), seven fallow deer (Dama dama) and two mule deer (Odocoileus hemionus), and from 50 free-ranging pronghorns in southern Alberta, were examined for viral agents. Captive animals were given ...

Unsporulated oocysts were recovered from the allantoic cavity of 5 chicken embryos inoculated with a single sporozoite of Eimeria tenella; some of these oocysts sporulated. Both macrogametes and microgametes are required for the formation of viable oocysts. The results conclusively demonstrate the bisexual nature of the sporozoite, suggest that sexual ...

Monensin was effective within the range 60-100 p.p.m. in control of coccidiosis in turkey poults in a series of laboratory experiments. Under conditions of heavy infections with Eimeria meleagrimitis and E. adenoides, 100 p.p.m. of monesin was significantly more effective than 60 p.p.m. in protecting weight gains. When light or ...

The role of C. penicillata as a latent focus of rabies in South Africa is discussed. A description of the colony life, feeding and breeding habits and the relationship of the Yellow Mongoose to the Suricate Meerkat and Ground Squirrel is given. Observations on the epidemiology and symptomatology of rabies ...

Subtherapeutic levels of oxytetracycline plus neomycin in animal feeds did not bring about increases in the quantity, prevalence, or shedding of Salmonella typhimurium in swine, calves, or chickens. In fact, the medication generally reduced the proportion of animals carrying S. typhimurium. The medicated groups were fed rations containing oxytetracycline plus ...

Sporulation rates of normal oocysts and oocysts isolated from lambs infected with coccidia and fed Aureo-S-700R for 25 days were studied at different temperatures. The viability and infectivity of the latter were also investigated. Temperatures of 5 and 10 degrees C inhibited sporulation of oocysts, but when the same oocysts ...

Melatonin (12-100 mug/day) administered via subcutaneous Silastic implants prevented or suppressed light-induced testicular recrudescence in adult golden hamsters. In addition, melatonin (150 mug/day) induced marked testicular regression in sexually mature hamsters maintained on photostimulatory long days. These results clearly establish that exogenous melatonin can inhibit gonodal function in adult male ...

Five groups of turkeys received C.U. strain Pasteurella multocida vaccine in the drinking water for one day. One group received the 0.1% level of sulfaquinoxaline feed medication at the time of vaccination, while 4 other groups received the feed medication 1, 2, 3 and 4 days after vaccination, respectively. Two ...

Two experiments were conducted (1) to explore the application of token reinforcement procedures in a maximum security correctional institution for adult male felons and (2) to determine to what extent the reinforcement procedures disrupted the day-to-day lives of inmate participants. In Experiment 1, an expanded reversal design revealed that the ...

Three trials were conducted to evaluate the efficacy of Linco-Spectin (LS) water medication on Mycoplasma synoviae (MS) air-sacculitis in broilers under controlled experimental conditions. Day-old chicks were vaccinated against infectious bronchitis and Newcastle disease virus and exposed to a broth culture of MS by the respiratory route. In each trial, ...

Roxarsone (0.005%) medicated chickens inoculated at seven weeks of age with Eimeria maxima oocysts had significantly higher pigment levels in blood plasma than did unmedicated controls. Unmedicated E. maxima infected birds had significantly lower pigment levels compared to uninoculated controls. Uninoculated roxarsone medicated controls showed no increase in pigment levels ...

Methyl benzoquate at 20 ppm or clopidol at 250 ppm in the diet show true coccidiostatic activity in infections with Eimeria tenella in the chick. Lerbek, a synergistic mixture yielding 8-35 ppm methyl benzoquate and 100 ppm clopidol, produced a partially coccidiocidal effect; relapses following restricted periods of medication were ...

A survey of Oxfordshire dentists showed that most practise prophlaxis of bacterial endocarditis, but that few follow currently recommended regimens. for example, prophylactic antibiotics are started one or more days before the procedure by 72 per cent of dentists, and two or more days before by 25 per cent. Eight-seven ...

New York City (NYC) transport medium was compared with Transgrow and Amies charcoal medium for the recovery of N. gonorrhoeae from clinical material. All three transport media were comparable within one day in transit. None of them consistently preserved N. gonorrhoeae for 3 days. However, for 2 days in transit ...

A case of cerebral metastases is presented in which the initial brain scan did not demonstrate the lesion because steroid medication had been started 18 hr earlier. The lesion was seen after the patient had been off medication for several days. Therefore, brain scans should be performed prior to starting ...

Cells forming rosettes (RFC) with sheep erythrocytes (SRBC) and rabbit erythrocytes (RRBC) were studied during the ontogeny of the bursa of Fabricius of the chicken. The frequency of SRBC-RFC was low but significant in the bursa of 15-day-old embryos, and increased therafter in an approximately linear fashion with the age ...

Feeds supplemented with lincomycin, novobiocin, tylosin and chlortetracycline suppressed experimentally inoculated in vitro sensitive Staphylococcus aureus skin populations on young chickens. The same effects were seen with drinking water medications containing erythromycin and spiramycin. Furazolidone-, bacitracin-, nitrovin- and virginiamycin-containing feeds and single intramuscular injections of macrolide antibiotics did not exert ...

Allergenic contact reaction to glove proteins and residual chemicals increased from 1980 onwards; circumstantial and technical evidence indicates that change from reusable to disposable latex gloves was a causative factor. Several protein fractions are potentially allergenic; if low protein gloves contain a dominant protein fraction, people with sensitivity may still ...

Gloves provide an essential barrier against contamination and are an important item of personal protective equipment. Gloves used in clinical practice do leak although there is no direct evidence that such leaks result in transmission of infection. Double-gloving is recommended in theatre as a means of reducing hand injury during ...

Twenty years ago, the wearing of gloves for non-sterile procedures was viewed as insulting to the patient as it made him/her feel 'unclean'. Today, gloves are worn for all procedures and are often wastefully used. There must be a fine balance between inappropriate and appropriate use of gloves and between ...

Aflatoxins were produced on fresh beef (in which bacterial spoilage was delayed with antibiotics), ham, and bacon inoculated with toxinogenic fungi and stored at 15, 20 and 30 C. Meats stored at 10 C were spoiled by bacteria and yeast before detectable levels of aflatoxins were produced. High levels of ...

Newly hatched chicks were medicated with chlortetracycline at levels of 0, 400, 800 and 1200 mg. per imperial gallon of drinking water, for the first 5 days in the brooders. Coliform microflora of the ceca were counted when the chicks were first removed from the incubator and at 2 and ...
