This study aims to determine the effectiveness of adding salt (NaCl) to ectoparasite Argulus sp. which infested goldfish (seedsCyprinus carpio) from the Gunung Sari Ornamental Fish Market, Surabaya. This research was carried out by taking samples from one of the ornamental fish cultivation sites in Surabaya with a total of 250 goldfish seeds. This study used 25 containers as research media with 10 goldfish seeds each. Each treatment was repeated five times, namely with the salt concentration P1 = 54 grams/liter, P2 = 108 grams/liter, P3 = 162 grams/liter, P4 = the negative group or the untreated group and P5 = positive control using methylene. blue 3 grams/liter. Ectoparasite examination Argulus sp.. conducted at the Parasitology Laboratory, Faculty of Veterinary Medicine, Wijaya Kusuma University, Surabaya. The completely randomized design method (CRD) was used in the study. The results were tested by ANOVA and a significant value of 5% (α 0.05). The test results showed that the treatment with methylene blue was not significantly different from the treatment of the three salt concentrations which had the same effectiveness. So the ANOVA test results show that all treatments are not significantly different.

The present research aims to know Stray cat health status in the Tegalsari sub-district market in Surabaya. This type of research is a descriptive study, experimental animals used were 30 stray cats on the market. Through examination of the liver function SGOT and SGPT. Blood serum Collection  of Stray cat in three markets in central of  Surabaya city, specifically in Tegalsari sub-district, namely the pasar kembang, pasar keputran selatan and pasar keputran utara, each market can take blood serum in 10 cats (Stray cat) as much as 3ml to test the value SGPT and SGOT, Data analysis using Analysis of Variant (ANOVA) the average value SGOT of Stray cat in pasar kembang 43.8+12.9 µ/l, pasar keputran selatan 79.0+ 50.3 µ/l and the pasar keputran utara 47.7+12.3 µ/l and average SGPT value on the Stray cat in the pasar kembang 98.0+48.7 µ/l, pasar keputran selatan 119.9+83.6 µ/l and pasar keputran utara 103,9+40.6 µ/l, especially the SGOT value can be significantly different (P<0.05) while the SGPT value is not significantly different (P>0.05). The value of SGOT and SGPT in pasar keputran selatan is higher compared to the pasar keputran utara and the pasar kembang.

The research aimed to know the degree of infection from egg calculated and increased numbers of white blood cells (eosinophils and lymphocytes) in wild cats (Felis catus). The samples of the research as many as 30 wild cats around the Around of Dukuh Kupang Surabaya . The examination was done by Mc Master method with 100x magnification and the calculated of white blood cells (eosinophil and lymphocytes). The results showed the degree of toxocariasis infection in wild cats (Felis catus) in Surabaya in Dukuh Kupang was seen from the average value of the 468.3 egg examination and the calculated of white blood cells (eosinophilic and lymphocytes) with an average value of eosinophilic 0.73 x103/μl and lymphocytes 10.72 x103/μl. This study used  descriptive method. Toxocariasis infection was included in the degree of moderate infection in wild cats (Felis catus) in Dukuh Kupang Surabaya with moderate degree.

Brucellosis (Keluron disease) is a strategic infectious disease with zoonotic potential, one of which is genus Brucella abortus. This research aims to detect Brucellosis in dairy cattle FH in Pagu District, Kediri Regency. This research uses two serological tests, namely the Rose Bengal Test (RBT) and the Complement Fixation Test  (CFT)  with descriptive analysis method. 30 cattle blood samples were taken from the coccigea vein. The blood was set aside at room temperature to form a serum. The serum that has been obtained is taken to the Department of Food and Livestock of Kediri Regency for  checking  the  RBT. The remaining serum obtained was sent to BBVet Wates for CFT examination. The results obtained show negative results on both tests. But one of the samples with the code S9 had gone through an abortion. This might occur due to other factors such as genetic disorders, the presence of viruses such as BVD, toxic agents and live vaccines during pregnancy.
